WHAT'S IN THE BOX?

In an all-Scythe fashion, the new Fuma 3 comes in a similar packaging like most Scythe coolers in recent years, a bit of imagery and some specs. Once everything is removed from the box, we will be left with the following items:

  • Scythe Fuma 3 Heatsink
  • Scythe Kaze Flex II Slim Fan
  • Scythe Kaze Flex II Fan
  • Installation Hardware AMD & Intel
  • PWM Splitter
  • Thermal Paste
  • Screwdriver
  • Manual

Down below you will also find a short summary of the coolers' specs:

COMPATIBILITY

As part of this update, Scythe updated their standardized Hyper Precision Mounting System to version 5. From a compatibility and usage point of view, we do not see any significant changes. The most notable change would be that the mounting brackets are now a straight piece of aluminum instead of having multiple edges and grooves. Down below you will find the full compatibility list:

Intel AMD
LGA1700 AM5
LGA1200 AM4
LGA115x  
LGA 2011-3  
LGA 2066  

INDIVIDUAL COMPONENTS

FAN

Compared to the Fuma 2 rev.B, the fans did not see any update at all.

In the center of the cooler, we still have Scythe's Kaze Flex II 25mm thick 120mm sized fan spinning at up to 1500RPM whilst pushing 67.62CFM at up to 1.5mm/H2O. 

Attached to the right heatsink, the slim 15mm spinning at the same 1500RPM whilst pushing 39.44CFM at .96mm/H2O found another home.

Both fans can be controlled using a PWM connection and combined to use a single header by using the included PWM splitter.

 

scyhte-fuma-3-fan

 

Although there hasn't been any update regarding the fans, we do not see this as an issue. The fans previously used are still relatively new, perform quite well, and didn't cause any quality concerns. Therefore, as long as they are still able to squeeze more performance out of the updated cooler, they can be a perfect fit.

HEATSINK

The component that got the biggest update is definitely the heatsink.

Even if it is still a dual tower design with 6 heat pipes, almost everything about it is new.

Instead of a very spacious design, the new Fuma 3 is a lot denser providing the fans with 52FPI instead of the previous 49. The X-pattern of the fins is also gone, creating a straight block design.

 

scyhte-fuma-3-heatsin

 

In the bottom of the heatsink, we still have 6 heavily bent heat pipes that allow the right block to be pushed back enough to not create any RAM compatibility issues whatsoever.

 

scyhte-fuma-3-heatsink

 

Although the cooler remains 154mm high, the sizes of each tower have changed. While the right (thin) heatsink sink became thinner, the left one got substantially thicker creating more overall fin area.

We attribute this change to the denser heatsink. Although the 15mm thick fan might have been strong enough to push the air through the old Fuma 2 spacious design, it might have not been enough to get through the new and denser heatsink. Hence the re-distribution.

BASE

scyhte-fuma-3-base

 

Another quickly missed change is the nickel-plated copper heatsink. Although the design remains the same, the base is now slightly wider, creating more contact area for both the CPU and heat pipes.

APPEARANCE

Design-wise, the Fuma 3 looks like a Fuma 2, but in the design of Scythe's recently released Kotetsu Mark 3. Similarly to the Kotetsu re-design, we have a blocky-looking dual tower design with 2 plastic covers hiding the top fins.

 

scyhte-fuma-3-dfesign

 

Usually, we are not the biggest fans of covers added to coolers due to the added noise potential that they create. However, similarly to the Kotetsu, Scythe made sure to add additional slits on the inner side of the covers to allow the air to travel through them instead of hitting them resulting in noise.

 

scyhte-fuma-3-design

 

Overall, we are quite happy with the re-design. The Fuma 3 still looks powerful while remaining simple and easy to integrate into existing builds. 

The two plastic covers on the top add to the simplistic design by being painted in a Matt-Black finish with two Scythe Logos stamped into each of them at the very center.

BENCHMARK

We benchmarked the cooler using our new CPU Cooler Benchmark Machine featuring 3 different Workloads at 320, 250, and 120W. For the Scythe Fuma 3, the 120W and 250W workloads apply as the cooler was unable to keep the CPU below Thermal Throttling once the 320W mode was being used. But that shouldn't be counted as a negative as there has not been a single air cooler capable of keeping up 320W permanently.

120W

scyhte-fuma-3-benchmark

 

Allowing the Scythe Fuma 3's fans to spin at their max speed at 120W kept the CPU at 35.2°C above ambient. Being 1°C colder than the Fuma 2, the update from Fuma 2 to Fuma 3 seems to have been fruitful.

 

scyhte-fuma-3-benchmark

 

After slowly lowering the fan speed in 10% steps, we were able to observe that this performance benefit applies all across the board. From start to finish, the Fuma 3 was slightly in front of the Fuma 2. 

250W

scyhte-fuma-3-benchmark

 

Upping the workload to a staggering 250W showed that the difference between the Fuma 2 and Fuma 3 is substantially bigger once the workload becomes higher. At 68.2°C, the Fuma 3 managed to land in between the Arctic Liquid Freezer II 240 and Gamdias Boreas P1.

Compared to the last-gen Fuma 2 rev.B, the difference has now become 3.8°C, a difference truly worthy to be called an update.

 

scyhte-fuma-3-benchmark

 

On the Noise-to-Performance graph, the Fuma 3 is now capable of creating a real line, something that the Fuma 2 was barely capable of doing.
Although the difference to the Fuma 2 is substantial at this wattage, the Fuma 3 is still quite behind the iconic Noctua NH-D15.

CONCLUSION

scyhte-fuma-3-design

 

Concentrating solely on the Benchmarks, the Fuma 3 is definitely a worthy successor to the Fuma 2 rev.B. Whilst running a lower workload, the difference between a Fuma 2 and 3 might be small, but once the heat is turned up, the Fuma 3's superiority becomes bigger and bigger.

Overall, the Fuma 3's performance is solid. It might not be the Noctua NH-D15 killer, but compared to other dual tower air coolers, it is solid to say the least, especially its noise-to-performance ratio.

 

scyhte-fuma-3-design

 

Design-wise, the Fuma 3 makes a solid impression. It looks clean, and powerful, while the new plastic covers keep the design modest while keeping it modern.

 

But one of the most important aspects of the Fuma 3 is the price. Currently (27/09/23), we are able to get a Fuma 3 for as little as 52€, a price which is incredibly hard to beat.

 

scyhte-fuma-3-design

 

As a whole, we are very happy with the changes Scythe implemented for the Fuma 3 compared to the older version. The performance was upgraded, and the design was refreshed to 2023 standards. Definitely the type of updates we like to see.

 

Due to the Fuma 3's solid performance paired with its excellent price, are can absolutely recommend the cooler for combinations up to Ryzen 7 or Intel I7 (7800X3D/13700K)
