Scythe Fuma Rev.B Twin Tower CPU Cooler

- Replaces the Scythe Fuma Twin Tower CPU Cooler

Scythe's Fuma features dual heatsinks to provide excellent performance and it's supplied with exceptionally quiet Slim Stream PWM fans.


  1. Twin-Tower-Design
  2. Compact height without loss of cooling performance
  3. Flexible Fan mounting
  4. Equipped with reliable Slip Stream Series fans
  5. Intel and AMD compatible

Tracing its roots back to renowned Mine 2, Fuma was kept smaller without sacrificing performance. Countless hours spent on testing and optimising formed a cooling device measuring 149mm in height. To compensate the smaller surface area, Scythe's researchers put a great deal of effort in tinkering a new baseplate design as well as redrafting the fin structure. They put considerable effort in optimising these two areas, a new twin tower CPU cooler with compact measurements while still providing high-end performance. It ensures reliable cooling to all processors available, whilst still being compatible smaller PC cases. The Revision B update now features full compatibility to current sockets including AMD's AM4 and Intel's LGA 2066 platforms.


The Fuma is made of two towers connected via six heatpipes to the baseplate. The twin-tower structure allows heating of the heatpipes while enhancing heat dissipation to the fins. The Fuma has been designed for ultra-quiet cooling but is an ideal overclocking cooler as well - at a very reasonable price. With its height of only 149mm the Fuma is lower than other high-end coolers currently available. This way, conflicts with side panels are avoided - even with smaller PC cases.

Flexible Fan mounting

It is designed for the use of up to three fans (two supplied). If two fans are used, flexible fan positioning is possible. In this way, the Fuma adapts perfectly to the case airflow. Furthermore, flexible fan mounting increases compatibility making conflicts with memory modules will be avoided.

Equipped with reliable Slip Stream Series fans

Included with the Fuma are two Slip Stream fans, a series valued by its customers for many years. It is characterised by its small fan hub enhancing air flow. With noise levels starting at just 13.0 dBA each, the PWM fans offer the best possible combination of noise level, cooling efficiency and durability.

H.P.M.S. II (Hyper Precision Mounting System II)

The updated Hyper Precision Mounting System II now features full compatibility to current sockets including AMD's AM4 and Intel's LGA 2066 platforms. A convenient mounting bar simplifies the installation process, while spring-loaded screws prevent uneven pressure distribution.

Customer Reviews

Very happy with the purchase, definitely worth the price.


Only gets to around 70-80 Celsius on a quite heavy overclock of 4GHz on my Ryzen 1800x (the highest I can get it to be stable) while my previous cheap CoolerMaster fan was almost 90 Celcius which caused the PC to shut down pretty quickly from overheating.

It's definitely one of the best air coolers on the market.
