Features:

  • 15% better in performance to noise ratio, FUMA2 has reached itself to next level. Dual heatsinks and fans accelerate and enhance heat dissipation for top-tier performance. 6 x 6mm heatpipes and copper plate base ensure heat from CPU and drop temps. Ideal for mainstream, gaming PC, even overclocking with high TDP processor(9900k, 9700k, 9600k,3700x, 3800x, 3900x, 3950x).
  • Asymmetrical design allows unrestricted use of any front RAM slot, and cut-out fin design gives clearance(55mm) of rear RAM slot(LGA2011/2066). Standing only 155mm tall, the cooler fits most PC case on the market.
  • Using Kaze Flex 120mm quiet fan(Fluid Dynamic Bearing), FUMA2 use two different thickness(25mm & 15mm) PWM fans rotating in opposite direction. This generates higher static pressure as well as stable airflow thus pushing cooling performance to maximum while keeping silent operation. Addition fan clips is included to add 3rd fan.

get this over noctua

I've owned a Noctua D15 (dual fan version) for awhile now and when I finally saw that Scythe released a version 2 of the fuma I was curious and decided to get it and test it out. It's been years since I last used a Scythe cooler. Before installing the Fuma 2 I ran a thermal benchmark using an absolute worst case unrealistic, brutal load and for that, Prime95 AVX with "Small FFTs" option was the obvious choice. My processor is a Intel I9 9900K with a P1 TDP manually set to 140 watts and a P2 of 175 Watts manually set in the bios. For monitoring I used HWINFO64 and let the test run for 20 minutes. After 20 minutes these where the results: Noctua D15 (dual fan version): Core Max temp: 79C CPU Package temp: 77C Motherboard CPU temp: 67C After installing the Fuma 2 I ran the same benchmark again with the Fuma 2 stock configuration which is having the 15MM slim fan in the front as intake with the 25MM in the center for pull. Here are the results after 20 minutes: Fuma 2 (stock config): Core Max temp: 82C CPU Package temp: 80C Motherboard CPU temp: 70C So the difference between a stock config D15 dual fan version and a stock config Fuma 2 is about 3 - 4C. Which falls in line with the difference between a D15 dual fan version and a D15S with its single fan. That's actually incredibly impressive for the Fuma 2 matching a D15S considering it has a lower surface area heatsink compared to the D15/D15S. The D15 heatsink without fans is: 160MM height 150MM width 135MM depth While the Fuma 2 without fans is: 154MM height 130MM width 131MM depth And its even more impressive that it was only 3 - 4C difference compared to the D15 dual fan version considering the D15 has more surface area along with bigger, stronger fans compared to the Fuma 2. The Fuma 2 fans only offer 0.9 (15mm) and 1.05 (25mm) mmH2O static pressure vs the 1.5 mmH2O of the Noctua NF-A15 PWM fans. That means the Fuma 2 heatsink is incredibly efficient at removing heat. So after initial testing I decided to see how much better the heatsink would be if I swapped the front 15MM fan with a full size 25MM fan. Since I have an extra Noctua NF-A12x25 from my previous project I had as shown in an older pic attached to this review to show my previous D15, I opted to use it. The A12 has a static pressure rating of 2.34 mmH2O so its a nice increase over the 15MM 0.9 mmH2O. I was really curious to see how well it performs with just one on the Fuma 2 because in the past I tried two of the A12's on my D15 and it barely a made difference. Only a 1-2C drop. After another 20 minute test these were the results: Fuma 2 (A12 push, Kaze Flex 25mm pull): Core Max temp: 78C CPU Package temp: 76C Motherboard CPU temp: 65C So with a simple swap of the front 15MM fan with the A12 I saw a nice 3 - 4C drop across the board. Just slightly 1C lower than the D15. So close its within margin of error. This really shows the Fuma 2 actually benefits from having stronger static pressure fans vs the D15. The heat fin system Scythe has going on really does work and isn't a gimmick. So I had another idea to see how well I can push it and decided to take advantage of the extra fan clips Scythe includes by mounting the 15MM fan on the back of the heatsink for a triple fan setup. These were my results: Fuma 2 (Triple fan): Core Max temp: 75C CPU Package temp: 75C Motherboard CPU temp: 63C Pretty impressive but for my daily driving I decided to just keep the dual fan config with the A12 in the front and the Kaze Flex 25mm in the center. It's a much cleaner look. In terms of build quality the Fuma 2 is identical to Noctua. High quality materials, nickleplated copper, 6 heatpipes, amazing heat fin innovation that really does help increase static pressure, and a mounting system nearly identical to Noctua's. I actually prefer Scythes clone of Noctua's mounting system because its mounting hardware feels more durable than Noctua's. Its pressure bar is a lot thicker and heavier and the mounting bar system is thicker and heavier as well. I also like how Scythe added rubber padding underneath the mounting spacers. Noctua doesn't do this so you just have bare, hard plastic pushing against the PCB while the Scythe has the nice rubber to prevent any chance of causing scrapes or scratches against the motherboards PCB. Scythe also includes a much nicer screw driver as well. Its nearly identical to the nice one BeQuiet ships with its coolers. An actual, fully function screw driver. In terms of "defects" I didn't notice any with my Fuma 2. Nothing was bent. Nothing has dents, chips, "black stuff" or anything like that. I know one user here left a review complaining of having a bent heat fin and "black" stuff left over from the Nickle plating process, but mine didn't come like that. Funny thing is, he praised Noctua for "not having that" while my very own D15 actually has that same black stuff on the side of its base plate that was left over from the Nickle plating process, came with bent fins that I could never bent back perfectly, and "chips" on its base plate. Which is nothing major and that's the purpose of thermal paste. To fill in those imperfections. I never dinged that against Noctua because that stuff is normal. None of it affects thermal performance. My $80 Morpheus GPU cooler I have sitting next to me on my desk in its box has the same problems as my D15. Even my ancient Noctua D14 came with bent heat fins and even its heatpipes where bent enough to push the forward heatsink inwards a bit. Overall I'm extremely impressed and happy with the Fuma 2. It has officially replaced my old D15 for me. It's more compact by being smaller, weighs less, doesn't block the first PCI-Express slot, has excellent ram clearance, identical build quality to Noctua, and looks great. Scythe did a fantastic job with it. For $60 you cannot beat this cooler. Stock configuration it competes with a D15S in performance but for $25-$30 less and comes within the ballpark of a D15 dual fan version for $25-$30 less as well. If you have any spare 120x25MM fans laying around and don't populate all 4 ram slots you can replace the 15MM fan with that spare and get practically identical D15 dual fan version performance but for far less. As of right now, I cannot recommend the D15 anymore. The Fuma 2 is the way the go.

Great Cooler With Plenty of Room to Spare

Prologue: The Wraith Spire cooler I had with my Ryzen 7 2700 was doing okay, but it would have big spikes in temps whenever the CPU was used to transcode. The temps would idle at 39-40C (22C Ambient) and peak at 65-70C (on Prime95). The Wraith Spire would frequently spin up its fans to cool the CPU, and it was very noticeable sound-wise. I had a Corsair Air 740 case (great for air cooling), but it was not reaching it's potential, so I was in the market for a new CPU cooler. I had looked at the numerous Noctua, beQuiet, and Cooler Master coolers, but either the color scheme was not my style, the price was too high, or the product wouldn't be compatible with my tall RAM (Corsair Vengeance RGB Pro). I had read about the Scythe Mugen 5 rev. B and the Fuma coolers (had previously had a Scythe cooler during my Phenom II days). But upon searching, I happened upon the Fuma 2. It had no reviews when I bought it, but I watched some YouTube previews of it, and it looked promising (Dual Tower air cooler with a slim front fan for max RAM compatibility). THE REAL REVIEW: The Packaging: Everything was packaged together nicely. Nothing was loose and all the parts that are listed were included. The cooler came with many brackets for Intel and AMD, but I can only vouch for AM4 since that is what I was using it for. The even included a very nice screwdriver (pic included), one that is long enough to reach the screws on the mount plate to screw it into the brackets on the motherboard. Installation: My case is the Corsair Air 740, so there was plenty of room for installation. I was able to keep the motherboard in the case and install the cooler. It utilizes the stock AMD rear bracket, so make sure you still have that if you're using this for an AMD build. Once you screw the mounts with the spacers and screws onto the AMD rear bracket, the next part is installing the Fuma 2 on the CPU. The Fuma 2 came with a generic TIM (Thermal Interface Material); however, I opted to use my trusty old Arctic MX4. Once the TIM is on, the Fuma 2 mounts on top of the CPU. Now the toughest part was screwing the cooler's mount plate onto the mounts on the motherboard. If the motherboard was out of the case, then it would have been much simpler, but I am lazy and was able to screw the mount in with some trial and error and some patience. Once the cooler is mounted, you can mount the 2 included fans (1x 120mm and 1x thin 120mm) with the included fan clips. Pay attention, because one of the fan clips is specifically meant for the thinner 120mm (it is made apparent with stickers). They do include an extra set of fan clips in the case you would either like to add a separate rear fan or install a regular sized 120mm in the front instead of the thin one that is included. Once the fans are mounted and plugged into the motherboard, the installation is done. There is an included 4pin fan splitter in case your motherboard only has 1 CPU fan header (my motherboard had 2, so I did not have to use it). Now on to the good stuff... Results: The Fuma 2 exceeded my expectations. I had stated in my prologue that I had to rule out some coolers due to RAM compatibility (the Corsair Vengeance RGB Pro has some of the tallest heatsinks around). With the thinner 120mm front fan, and the offset the cooler has, it clears the RAM slots and the PCIe slots perfectly fine (pics included). With the black top on the cooler, it blends into my case pretty well. Thermals are great as well. I had stated my previous temps with the Wraith Spire cooler on my Ryzen 2700 was idle at 39-40C (22C Ambient) and peak at 65-70C where the fans would be full speed and would make itself known with its loudness. With the Fuma 2, my idle temps are 30C-33C and my peaks are 55-57C. Those peaks temps are great, if I wanted to overclock more, I could. But I chose the 2700 for its lower power draw. So at stock volts, I am able to get to 3.7GHz on all cores. I'm sure I could probably go over 4.0GHz if I upped the voltage, but I will leave that to someone else. The thermals improvements are beyond great; however, the best thing about it, is the near silent operation, even during those peak temps. I set a very low fan curve, so unless it goes above 65C it will never reach full speed. I have tested the fans at full tilt, and it is audible, but not as loud as the Wraith Spire cooler. Conclusion: If you have an AM4 CPU and are still utilizing the stock cooler, the Scythe Fuma 2 is a great option. The price does pit it against some comparable Noctuas and beQuiet coolers. But the form factor, color scheme, design, and compatibility were perfect for me. And the results match it's quality. I am impressed again by Scythe. I hope that they will get more attention from more of the YouTube reviewers, but unless you are one of the big cats, great coolers like this go under the radar.

Scythe has a winner here.

Great cooler, from my testing appears on par with Noctua NH-U14S or NH-D15S. It is also about as easy to install, the mounting system is good and it comes with a nice screwdriver that is useful for other things. Does not interfere with RAM slots at all. I think Scythe will be my go-to CPU cooler from now on for performance and value, knocks everything else out of the park. I believe this cooler could be even better with higher RPM fans, but it would likely hurt its silent aspects. The only negative I have is that the fins are rather sharp compared to others but they won’t cut you unless you are completely careless.

Awesome air cooler for 3900x!

I was using the Wraith RGB that came with my 3900x on my Aorus Elite WIFI for about a week. It's nice and compact. The RGB visuals are nice well, but jeez that fan at higher rpm is loud. Given that my case is against my desk, I can't see the lights on the cooler so I figured I would try something a bit better as far as noise and cooling. I decided on this Fuma 2 based on recommendations online and boy was I disappointed at first. I turned on my computer after installing it and immediately ran CPUZ stress test against 24 threads. I was using hwmonitor to track my temps and they immediately jumped to 95c. With the Wraith I was getting 84c after settling for a few minutes. I was puzzled to say the least. I ran it a few times and got the same result. I was about to just pack everything up and do a return and removed the heatsink...then I noticed I forgot to take the sticker off the mounting surface...doh! This made my hopeful again and reapplied the provided paste and reran the stress test. With this cooler the stress test settled at 74C. That's a good 10C drop and it's quiet at 100% load across all cores. I'm very happy with this cooler as I don't like the idea of liquid being near my computer with AIO cooling. Installation is simple for AM4, which I'm glad about since I had to remove the cooler because of my dumb mistake. I'm now a Scythe fan. The value and performance of this cooler is great. The one thing I noticed is that my idle temps were lower and consistent with my Wraith RGB at 45C, but this one fluctuates between 44C and 51C. I'm not entirely sure what causes that though. It could be due to the fact that I'm using the splitter on the two fans so the PWM control is acting weird. DON'T FORGET THE STICKER ON THE MOUNTING SURFACE LIKE I DID.

Great mid-price cooler with high-end performance!

This is a terrific midrange cooler with high-end performance! This thing will hang with a Noctua NH-D15. The only spot the Noctua may best the Fuma is at very high fan speeds. If your CPU ever reaches 80-90 degrees, (which it shouldn't be) the Noctua will probably net you 2-3 degrees lower. And even that will be highly dependent on the airflow in your case. Simply put, I don't think there are, currently, many air coolers that can compete with the price to performance offered by the Fuma 2. It's very quiet, though you will hear it a little bit at the highest of RPM, which is most coolers. The included fans are great and run very well, although, I swapped mine out with an even quieter model for the middle fan and an LL series fan from Corsair to match the rest of my build. Keep in mind that the slim fan will likely fit on the front of the cooler and not interfere with any of your four RAM slots, however, if you want to use a normal size fan on the front, such as an RGB fan, it'll likely block your first ram slot, unless you mount the fan higher on the cooler and closer to your case's side panel which will make the cooler not look as flush and streamline. I had four 8GB sticks of RAM and ended up removing two and just going with two 8GB sticks so I could keep the fan flush and perfectly inline with the cooler. My LL Corsair fan blocks the first RAM slot. This cooler is very large but looks so aggressive and imposing, once in your build. Other than that, mounting was as easy as it could be for a large air cooler. All mounting hardware is included as well as instructions. I'm currently running an Intel 8700k overclocked to 4.8ghz on all cores and when running an AIDA64 CPU stress test, my temps never go above 70°. I'm also using a thermal pad and not paste and it works amazing. If you're someone who prefers paste, you could probably bring your temps even lower than mine with some nice Thermal Grizzly Kryonaut or something similar. At the end of the day, this is one of the best bang for your buck coolers avail, with great performance and a terrific look. Highly recommend!

Makes Distributed Computation (folding@home) Feasible

This air cooler saved my computer and let me continue to run folding@home 24/7. I recently started running my stock computer 24/7 with the distributed computation software called folding@home as part of a community of hundreds of thousand computers helping scientists calculate protein folding of the virus that causes COVID-19. I was pleased to be able to help out with my 7-year old computer. (Fractal Design Define R4 midtower case, Intel i5-3570 CPU, 4 x 4 GB RAM, 3 intake fans and 1 exhaust fan and Intel stock air cooler).. Everything started out OK but after a few hours the CPU’s temperature climbed to 90 C at 100% utilization. I adjusted folding@home to the medium power setting so CPU usage dropped to 65%. I reseated the stock cooler and used new thermal paste as the old paste was 7 years old. The CPU temperature dropped to 85 C but my hard drive was no longer recognized by the computer. Thinking the 2-year old HDD had failed, I installed a new SSD. After 1 day the SSD was no longer recognized by the computer. I shut down the computer overnight and the next morning the SSD worked fine, with no loss of data. My theory is that the CPU overheated enough to cutoff one SSD (I use 2 other internal SSDs and 2 external HDDs) without shutting off the computer. I purchased the Scythe Forma 2, installed it and resumed running folding@home at its medium power setting. After an hour with the CPU running at 65% utilization the CPU temperature never exceeded 65 C and the computer remained whisper quiet, with the two air cooler fans running at 350 rpm (1200 rpm max). I couldn't be happier. The directions were pretty clear except for the guidance on which direction to place the fans so they push air from front to back. However, there were excellent video directions on YouTube. The air cooler has dual towers and dual 120 mm fans so the cooling capacity increased dramatically from Intel's stock cooler. I have to say that until I started using folding@home there had been no problem with the CPU temperature. I don't use the computer for gaming but I often use several programs at the same time such as Adobe Photoshop Elements, Family Tree Maker, Microsoft Excel, and Outlook. When I upgrade to a new computer I will be able to take the Scythe Forma 2 air cooler with me since it can be used with either Intel or AMD CPUs. I will just put back the stock Intel cooler and donate a functional computer. I reinstalled the HDD to see if the CPU temperature was the problem.. The HDD workEd fine, with no loss of data. After 24 hours of continuously running folding@home at medium power the CPU did not exceed 65 C. My CPU has a 77 W TDP. I am now able to run the CPU at 65% utilization 24/7 so I am back to helping scientists calculate in their research of COVID-19. Very pleased with the noise level, price and ease of installation. There was no need to remove the motherboard, the RAM, or the GPU. This was the first time I installed an aftermarket air cooler on a computer and there were no disasters.

Good quality cooler, but not as clean looking as more premium brands

Like others have said, the performance of the Fuma 2 (and Scythe's lineup as a whole) seems comparable to premium brands like Noctua, maybe off by only a few degrees under heavy load. However, the presentation is somewhat lacking. I received a cooler with large scratches on the baseplate and slight marks that looked like previous use (separate from the large scratches which didn't line up with the corners of the possibly previous mounting), and the fans had some cosmetic damage on the labels and fins. The accessories seemed new, so it's hard to say whether this was used but sold as new, or just accidental damage from QC testing before being sent out for distribution. Got a replacement from Amazon which still had scratches on the baseplate and minor cosmetic damage on the fans, but the baseplate scratches were much lighter compared to the first. Cosmetic imperfections shouldn't affect performance (unless scratches happen to be deep enough to affect the thermal paste's ability to fill in gaps) so this cooler is still highly recommended for anybody looking for top-quality air cooling at a less than premium price. Just be aware that the cooler will likely come with some minor cosmetic damage, which may matter to people that wish to keep their systems looking pristine. (For comparison, previous Noctua coolers I've bought came looking mostly perfect, with smooth mirror-finish baseplates and very new looking fans. Again, this is not likely to affect performance, but just something to keep in mind if aesthetics matter to you.)

Cools R9 3900x super well - better than stock cooler experience with a R7 3700x

Used on a ryzen R9 3900x and msi x570 gaming edge with wifi. All memory banks are full with 32gb corsair sticks 128GB total). The cooler is in a corsair 200r case so I was limited to 160mm high - eliminating many options. First, Installation was straight forward - but also provided a visual challenge aligning with the cpu. I had to redo three times (along with cleaning off old and applying new thermal paste - fortunately I had ordered extra) until the thermals [without fans] were behaving [yes it was the paste. First time all was on one side, next time the heatstack flipped back unexpectedly while I grabbed the screw driver... Next, was fans. I was worried about heat after reading 3900x reviews (all great but most noted the heat as a limiting element). So I used different fans (a noctua af 12-15 on the front [max rpm 1850 vs 1200], and two corsair sp120 fans (2350 max) for the middle and rear. (I had tried the noctua af12-25 (up to 2000) on the rear but the fuma2 clips dont work very well with noctua 25mm fans and the the corsair fans worked great). Note: I used this fan arrangement after watching a youtube head to head challenge between the fuma2 and noctua D15, where the fuma 2 with three fans cooled a few degrees lower than the d15. OK - in the end, I love the result. After tweaking the fan curve in the bios, I idle around 43C [cpu at 3.8 mhz] and under load it operates between 60 and 65C [cpu at 4.3-4.6 MHz]]. [So far i have run pass mark memory checker, and cinabench render tests ... without going over 69C; my next test is rendering an 8K file in Premiere];. [Ps. This is better than my R7-3700x build performed with its stock wraith cooler - even though the 3700X has a lower 65w tdp - although the stock cooler rgb it looked much nicer than my 'franken-fan' black & tan setup does.]

Huge improvement over stock Spire cooler.

This cooler did a great job of cooling down my Ryzen 5 2600x. With the Spire cooler I was already hitting 75C + before I shut down the stress test. This was without me even overclocking the Ryzen. With a mild overclock at 3900MHz the Fuma 2 cooler held the Ryzen under 60C on Cinebench 15. Other than stock I have only used the Noctua NH-U12S Chromax which is on my son's gaming pc. The price is of course more but the build quality on the Noctua feels slightly better. I did have to straighten out a couple of the cooling fins on the Fuma 2 and the black top plate is just as fragile but in all honesty I may of been the one who bent them. Handle with care. A tip when mounting the brackets with AMD. Just put one rubber spacer and a bracket screw into the backplate to hold it in place. Install one bracket as instructed. Once the first bracket in on it will also hold the backplate in place and you can install the 2nd bracket. I did not remove my motherboard to install the cooler. I installed the fans onto the cooler first before mounting the cooler to the motherboard. I did need a flashlight to make sure I aligned with the screwdriver with the mounting screws since the channel cut into the fins has enough room in it to actually miss the screws with the screwdriver. I did order an optional Kaze Flex fan to add additional airflow ( probably overkill). The fans are so incredibly quiet. I do wish the splitter cable was just a bit longer. Overall this was a great purchase and does an excellent job of cooling. Definitely recommend.

Great product for mid size build

My Ryzen 3600 was getting hot with the stock cooler with a 100mm fan. A friend gave me a compact after market cooler with a 120 mm fan and it was only a slight improvement. I was still getting idle temps of 50c and gaming at 75c My problem is that I decided to use the Phanteks 350x mid size case, and it specs a max cooler height of 160 mm. That rules out all 140 mm air coolers and most 120 mm coolers. I checked some reviews and website and found the Fuma 2 with a unique design, and decided to try it out. The mounting bracket and mounting the tower was straight forward and easy. However, it was more difficult to place the fans and get all of the cables routed. I do not fault the Fuma 2, but the fact I choose a mid tower and the Fuma 2 fills the case. The good news is that it works exactly at advertised. The offset design and 15mm front fan is 100% clear of all memory slots. The unit has additional thermal cooling capacity then stock coolers so the fans run slower and much quieter. My average temps have dropped down to 35c idle and 60 gaming. I am very happy.
