Prologue: The Wraith Spire cooler I had with my Ryzen 7 2700 worked well but had large temperature spikes when using the CPU for transcoding. Idle temperatures ranged from 39 - 40 °C (at 22 °C ambient temperature) and peaked at 65 - 70 °C (on Prime95). The Wraith Spire would often crank up the fans to cool the CPU, and it was very noticeable in the sound. I had a Corsair Air 740 case (great for air cooling) but it didn't live up to its potential, so I looked for a new CPU cooler on the market. I looked at many coolers from Noctua, beQuiet and Cooler Master but either the color scheme wasn't my style or the price was too high or the product is not compatible with my large RAM (Corsair Vengeance RGB Pro). I read about Scythe Mugen 5 rev. B and Fuma coolers (I previously had a Scythe cooler during my Phenom II days). But when I searched, I came across the Fuma 2. It didn't have any reviews when I bought it, but I watched a few YouTube previews and it looked promising (dual tower air cooler with thin front fan for maximum RAM compatibility). REAL REVIEW: Packaging: Everything was well packed. Nothing was dangling, all parts listed were included. The cooler came with many Intel and AMD mounts, but I can only vouch for the AM4 as that's what I used it for. The kit even included a very good screwdriver (photo included), long enough to reach the screws on the mounting plate to screw them into the brackets on the motherboard. space for installation. I was able to leave the mainboard in the case and install a cooler. It uses a standard AMD rear bracket. So make sure you still have them if you use them on an AMD build. After screwing the grommets and screws onto the AMD rear bracket, the next part is to install the Fuma 2 onto the CPU. Fuma 2 comes with Universal TIM (Thermal Interface Material); However, I settled on my trusty old Arctic MX4. Once TIM is activated, Fuma 2 is mounted on the processor. The hardest part was screwing the cooler mounting plate to the brackets on the mainboard. If the motherboard was outside the case it would be a lot easier but I was lazy and through trial and error and patience I was able to screw the bracket on. Once the cooler is installed, you can install the 2 included fans (1 x 120mm and 1 x thin 120mm) using the included fan clips. Please note that one of the fan terminals is specifically designed for the thinner 120mm (you can tell by the stickers). They include an extra set of fan clips in case you want to add a separate rear fan or install a regular 120mm fan in the front instead of the included slim fan. Once the fans are installed and connected to the motherboard, the installation is complete. A 4-pin fan splitter is included in the kit in case your motherboard only has 1 CPU fan connector (my motherboard had 2 so I didn't have to use it). Now for the good. Results: Fuma 2 exceeded my expectations. In my prologue I indicated that I had to rule out some coolers due to RAM compatibility (the Corsair Vengeance RGB Pro has some of the tallest heatsinks). With a thinner 120mm front fan and offset radiator, it cleans the RAM slots and PCIe slots very well (photo attached). With the black lid on the cooler, it fits very well in my case. Thermocouples are great too. I've stated that my previous temperatures with the Wraith Spire cooler on my Ryzen 2700 have ranged from 39-40°C (22°C ambient) when idling and peaked at 65-70°C when the fans are at full speed ran and made themselves felt. The Fuma 2 has idle temperatures of 30-33°C and peak temperatures of 55-57°C. Those peak temps are great, if I wanted to overclock more I could. But I chose the 2700 because of its lower power consumption. So with standard voltage I can reach 3.7 GHz on all cores. I'm sure I could probably go over 4.0GHz by increasing the voltage, but I'll leave that to someone else. The thermal upgrades are amazing; The best part, however, is that it operates almost silently, even at peak temperatures. I set the fan curve to very low so it will never reach full speed unless it goes above 65C. I tested the fans at full blast and they are audible but not as loud as the Wraith Spire cooler. Conclusion: If you have an AM4 processor and are still using the stock cooler, the Scythe Fuma 2 is a great option. The price really compares to some comparable Noctuas and BeQuiet coolers. But the form factor, colors, design and compatibility suited me perfectly. And the results match its quality. Once again I'm impressed by Scythe. I hope they get more attention from more YouTube reviewers, but unless you're one of the big cats, great coolers like these go unnoticed.
