Like the last time we reviewed the Scythe Mugen cooler, the essence of the upgrade reasoning was to offer new hardware for LGA1700 support, and it seems Mugen wasn’t the only one to receive this treatment. Scythe also submitted their most recent FUMA iteration for testing, and while the main concept is that they’ve provided updated hardware, there’s a lot going on that you might not realize right away. Even though the overall design hasn’t replaced much, there are parts of a dozen important little points that only the sharpest eyes would notice.
Over time, things want to change, and while FUMA loses LGA775 on the newer model, Scythe has taken a close look at FUMA 2 and made some minor but vital changes. First, we are now cooling the tower with a pair of Kaze Flex II PWM fans, any of which supply more airflow and use Reverse Jet Flow to further increase fan functionality. This newer example is also slightly thinner than its predecessor, as the main fan is thinner and cuts two millimeters intensity between the cooler and RAM for more free space. Sure, there’s more under the hood, but digging into the details at this point would make this introduction too long so early in the game.
To bombard you with all the little details, let us introduce you to the newest FUMA ever to hit the market, the Scythe FUMA 2 Rev. B. At first glance, it’s easy to assume this is the same cooler with the LGA1700 hardware in the box, and while that’s not entirely wrong in this review, we think Scythe has done a lot to deserve your attention in what could be the next dual-turn CPU air cooler for its next build.
We combined the previously discovered specifications of what was presented on the box and the product page. In it we can see that the Scythian FUMA 2 Rev. B is also known as SCFM-2100, and the latter is vital to verify to make sure you are getting the newest version. The CPU socket has been expanded, but it is no longer the LGA775 in favor of the LGA1700, which is a fair industry while all existing HEDT and non-unusual sockets. With AMD, it’s returning to the FM1 and AM2 sockets, adding everything since then.
As for the size, the FUMA 2 Rev. B is 137 mm wide, from one fan clip to another, the intensity is reduced this time to 129 mm and the tower rises to 154. 4 mm. With enthusiasts included, once installed, the FUMA 2 Rev. B will weigh 1000 grams, but provides unlimited free space for RAM versus this tower cooler. Behind, concessions were made to the fins, leaving users with 55mm of memory area to the left of the socket.
We also see mention of the six 6mm diameter heat pipes used in the chiller structure, and also that the base plate is made of copper, which is nickel-plated, which is the same for heat pipes. What is not disputed is that the fins are made of aluminum and there are forty-nine stacked.
Cooling of the towers is provided through a couple of enthusiasts delivered in the box, both editions of Kaze Flex II enthusiasts from PWM. Both have a length of 120 mm, but the front fan has a thickness of 15 mm, while the fan at the moment has a thickness of 25 mm. The slim fan has 1500 rpm as maximum speed, delivers 39. 44 CFM airflow, 0. 91 mmH2O static voltage and operates at 23. 8 dB(A). The 25mm edition also rotates at 1500 rpm, but will generate a noise of 67. 62 CFM, 1. 5 mmH2O and 28. 6 dB(A) sealed precision fluid dynamic bearings. As always, it all comes down to the load. However, while many refrigerators this way charge close to $100 or even more, Scythe has selected a more affordable route.
Looking around, we found the SCFM-2100 listed on Amazon for only $65. 99, which turns out to be a big deal, as only a few chosen coolers arrived here with double-turn designs, being affordable, but without failing in performance, or is it a bummer to install. However, we think that with everything Scythe has put into the new FUMA 2 Rev. B, this is possibly enough to convince you to join their team and grab one of those coolers for use.
Like Scythe, they opt for a matte black background, where we place the compatibility and the call and the Scythe logo at the top. In the middle is a near-life-size symbol of the FUMA 2 Rev. B discovered inside the box, and we also saw mentions of Kaze Flex II enthusiasts in use. Other than that, there’s a cooler ninja-like character who calls and room number.
On the right side of the packaging, we have the features indexed. The first talks about the counter-rotation enthusiasts used or the inverted jet. Then comes the improved compatibility with Kaze Flex II PWM enthusiasts and the asymmetrical design. Finally, Scythe promises that if you missed the icon on the front, this tower supports the LGA1700 with the hardware in the box.
On the back, we locate Scythian addresses around the world, to the left of a couple of barcodes. The back of the box is the only position where we found that the canopy guarantees the information, it would probably be on site, but if it is, it buries itself deeply. However, with the FUMA 2 Rev. B, warranty situations cover its use for two years from the date of purchase.
The specifications cover the last panel of the case. The most sensible are the dimensional representations that show the enthusiasts and the tower, with the best main points measured and shown. A condensed list of specifications for the tower and enthusiasts is as follows, but provides the POS visitor with a smart concept whether the FUMA 2 Rev. B will fulfill their wishes or at a glance.
Packed identically to FUMA 2, our FUMA 2 Rev. B is enclosed in a layer of cardboard. The thin fan rests on the most sensitive part as we have it, away from the other parts. The tower is located in the middle, with foam added for extra protection, while the 25mm fan passes between the towers as shipped.
The bottom box contains all the hardware and equipment you need to get started. A final step to keep the cooler in the best conditions for our photographs is that the base of the tower is supported by cardboard so that the tactile surface arrives in good condition and without damage. .
From the front of the FUMA 2 Rev. B, we see forty-nine aluminum fins, some smaller, some wider. Under the pile of fins, we see very compact elbows to orient the pipes well at the front of the cooler.
In this asymmetrical design, the front of the tower moves away from the RAM but is pushed back so much that it now sits atop the mounting hardware. The cooler timing part has the 8 lower fins trimmed to allow the 55mm h8 RAM to have compatibility underneath. We also saw how comfortable the corners are at the moment with the set of ailerons in the front section.
From the rear, the view is similar to that of the front, but the flat edges of the 8 lower fins contrast with the sawtooth trend that occurs on the fins above. The six heat pipes are well spaced in the tower and even so, we can I still have to assemble the equipment.
If you look closely, you can see that the smaller fins are tilted on either tower, restricting airflow as you move the fin arrays. Also see the notches, one row on the front of the front die and two on the moment stack, where cable fan clips hold enthusiasts to the cooler.
The fins are thicker at the edges, just before touching the edges that help the fans. All other fins are flat on their faces, while the opposite ones are irregular, but the intensity is uniform in the valley. In addition to the other tricks at play here, this is another one to help take advantage of the limited airflow produced by those fans.
The base of the FUMA 2 Rev. B is a two-component aluminum block with a copper plate underneath. The aluminum component is cut into a finned precooler, but the center is cut to accommodate the crossbar and spring mounting bracket. Mounting screws loaded. Like copper tubes, the touch surface is nickel-plated to improve appearance and oxidation.
We do not find symptoms of thermal paste or solder at the base of the heat pipes, we are sure that it is more likely to be paste. See a bit of the slot that allows access to mounting fixtures, but we have a better view ahead.
We have already commented that the touch surface is nickel-plated, and after cutting the protective sticker, we can see the circular marks that remain from the device. Located in front of a ruler, we locate the convex base, which increases the assembly tension and standardizes contact with the IHS.
The most sensitive of the FUMA 2 Rev. B keeps the fin arrangements in the shape of a dog bone, but the butt gives 3 channels. The middle one is intended for the factory to install the crossbar, while the two near the sides are used to mount screws with a screwdriver provided through Scythe. The tips of the tubes aren’t that pretty, but the logo stamped in the middle of the paintings is a fantastic but sophisticated extra touch.
On the left we have the LGA1700 brackets that are used in particular for those who have this system. The rest of the main users would possibly want the backplate; at least, Intel users will. The bolts are adjustable, but you want to remove the rubber insulation covers to replace them with plug brackets. The brackets on the right are universal for all other plugs. AMD and Intel users will use those media unless you fall under the LGA1700 category.
The black spacers on the left are used with AMD installations as spacers. Then comes a set of knurled nuts that attach the brackets to the HEDT spacers to the right or at the most sensitive point of the backplate bolts. AMD users receive a set of screws that are screwed into the factory backplate to attach the bracket to those plates.
As we said, Scythe includes a screwdriver, just for mounting the basic hardware on the motherboard, but it’s also long enough to go through the tower slots to connect the cooler to your hardware. Scythe also includes a 4-pin Y-cable splitter that monitors PWM on the black male head but only powers the white male head from either the motherboard fan head.
Although Scythe sends a huge tube of thermal grease, there is enough for 3 attempts to apply it inside. Above, we find a couple of fan clips intended for the 120 Slim fan, however, it is quite simple to see that the other 4 fan clips have longer intermediate sections to accommodate thicker fans.
Of the two fans, it is the Kaze Flex II PWM Slim fan, with a thickness of 15 mm. It has the component number KFS1212FD-P, which will have to constitute either functionality or pressure, at least in our heads. Continuing, everything In this fan is black, the frame, the rubber, the nine blades, even the sticker. According to this theme, the 4-pin PWM cable is lined and black to help hide it.
Beyond the sheathed cable coming out the other side of the fan, it is the thicker of the two, as the component number KFS1225FD15-P escapes. Again, everything is black, it’s just a thicker frame with wider blades, and this fan rotates in the opposite direction to the 15mm thick we just saw.
Of course, you want some commands to install FUMA 2 Rev. B, and Scythe provided this folded sheet of paper for compatibility in the box. Once unfolded, there are wonderful renderings to follow, a full list of pieces, and even text to help you through the process. No matter what socket you support, it shouldn’t take more than a few minutes to install that CPU cooler and be fit to act. Even an amateur can set up this one.
When our AMD system, we had to remove the most sensitive plastic clips from our board and set them aside, as well as factory screws. Then we installed the black plastic spacers that have compatibility on the protruding parts of the AMD backplate. Once they were in place, we placed the brackets on the spacers and the screws provided in the box; We ran them until they almost noticed.
The next thing I needed to do was remove the label from the base of the cooler, apply the thermal paste on the processor, and place the cooler on top. As mentioned, for the mounting screws of the cooler, you will need to put the screwdriver in the slot. on the front of the FUMA 2 Rev. B. Switch between the two until the screws cannot rotate, then we can slide the enthusiasts into position.
Despite the fact that the thin fan turns out to rise in height in the tower, we divide the difference in the fin net, and the ends of the pipes are still the highest point of the cooler. The fan lives in the most sensitive part of RAM as we have it, but for those who need extra VRM cooling, it can slide enthusiasts down to blow air under the cooler.
We unplug the front fan to see the hole between the RAM and the fan. Switching from a 17mm thick fan to a 15mm fan is a wise decision, as access is now completely free, allowing core users to access any RAM.
Taking a step back, the amount of area required for FUMA 2 Rev. B can have drawbacks. Here we can see that the 8-pin connector is limited and there is a ceiling at the height of the RAM for HEDT users, but the area on the back leaves enough free space from the rear I/O cover.
Once on the bench, we see that the RAM view has been changed to a component leak of the rear I/O cache, and on some motherboards, this is a loss of visual illumination. However, the overall view blends more with the construction than the lacheck iteration of this cooler.
To see our method and know what happens in the creation of our charts, see our article CPU Cooler Methodology and Testing 2020 for more information.
Seeing that bright red line in the third part of the graph doesn’t sound so good, but let’s get a little bit of perspective. First of all, this is the seventh most productive air cooler we’ve tested with this existing system, which is a smart achievement for any CPU cooler. At 59. 6°C, the FUMA 2 Rev. B is 3. 2 degrees the SE-207-XT Advanced, the most productive of the bunch, but Scythe beats many of the fan favorites on our chart.
By switching inventory to our overclocked profile, we provided more tension and warmth to the cooler, and the FUMA 2 Rev. B didn’t seem to care much. Going from 7 to 5 in CPU air coolers is a wonderful way to display in this chart. With a temperature now of 65. 8°C, Scythe is just 2. 2 degrees ahead of any CPU air cooler seen.
To allow the FUMA 2 Rev. B to show us everything it has to give, we put the enthusiasts at 12V and let it eat. Scythe manages to raise its rating with a result of 62. 7 ° C. Not only have we lowered the temperature through 3. 1 degrees relative to the PWM curve, but the FUMA 2 Rev. B is in the current place, 1. 2 degrees the SE-207-XT Advanced.
Although not an exceptional result, the FUMA 2 Rev. B operated with the original parameters with only 27 dB as the maximum amount of noise coming from the cooler. Achieving this result, the slim fan spins at 904 rpm, while the 25 mm fan works. at 1110 rpm. Virtually inaudible in maximum conditions and quieter than the SE-207-XT Advanced, which is something to think about when looking into the previous trio of cards.
The overclocking app made enthusiasts spin faster, but the overall noise point remained somewhat limited. Most users with 33 dB noise in busy scenarios would probably be gaming, working, or out while the PC transcodes or renders and probably won’t bother them. through CPU fan noise. The slim fan ran at 1154 rpm this time, while the thicker fan reached 1134 rpm.
Although we allowed enthusiasts to make as much noise as they could, we were very happy to see that we only reached 48 dB. Yes, of course, it’s an audible level, but in many other double-turn designs in this painting. , Scythe did well. Since the thin fan is now at 1506 rpm and the thick fan is at 1540 rpm, we expected more noise and with the headphones, you can run the cooler at full speed and not disturb everyone in the house.
There is no doubt that we have continued to communicate about the SE-207-XT Advanced, and that is because, currently, it is the leader of the class. However, this does not mean that this is the end of the discussion. The 207 makes concessions for nothing, really. This is a giant two-tower design with rugged fans and while functionality is key, we expect it to have cool low-profile RAM, as ID-Cooling felt it wasn’t that bad. This is where a cooler like the FUMA 2 Rev. B stands out. It can work close to the competition, but it also makes concessions to clear RAM and attenuates the noise emitted in the ears.
Considering the 207 had the thrill of taking in the air from a pair of 25mm fans, it’s easy to see where the thermal merit comes from, but overall, we think the Scythe FUMA 2 Rev. B is the apparent selection of both. . For the more sensitive, their load is almost identical, so it is large and cumbersome, or large, but pleasant, passes the call.
With that out of the way, we can transfer to the style, which is the same as before with the FUMA 2, but this time the rubber of the enthusiasts has been replaced by black for the Rev. B. Otherwise, without seeing any more media in the hardware box, they are identical. We enjoyed it then and now, yet the saying “if it doesn’t break, don’t fix it” applies. We are looking for a refreshment or an additional appeal like pipe tip covers, a chrome logo, the so-called Scythe painted on it, something. To be honest, we can’t complain about our use and the effects we’ve achieved by using it.
The installation is undeniable and everything you want is in the box, making things much less difficult for the customer. The curtains are undeniable to order and the tips contained in the commands answer any questions that may arise. Once installed, the functionality is higher than average and it’s among the ten smartest CPU air coolers in our charts, the seven smartest in fact, and that increases as we go along.
Even with the number of thermal functions Scythe was able to produce, they didn’t cause our ears to bleed like they did. There are CPU coolers that make less noise, and there are coolers that work better thermally, but Scythe has found a great combination of everything. necessary for a wonderful addition to the CPU cooling market.
Because it can take on the big ones on the charts, do it with less noise and offer it globally for a similar cost, it shows how well Scythe idea through what they did. At first glance, it’s hard to see all the magic happens, but everything is revealed once in your hands and connected to a processor.
The biggest boost here is coming with LGA1700 support, but at $65. 99, Scythe makes it tricky for us, as we don’t see why this isn’t compared to many of its competitors. That said, if you like air coolers and not AIO to cool your power-hungry processors, Scythe deserves a thorough review and is something we can recommend to many customers in the long run.
