Air cooler Scythe Fuma 3 12 cm Black 39.44 cfm 114.89 m³/h

The Scythe Fuma 3 is a dual-tower air cooler designed for CPU cooling in desktop systems, offering a compact asymmetrical layout that preserves RAM clearance and makes installation possible even on Mini-ITX motherboards. It uses six 6 mm heatpipes that connect two heatsinks to a nickel-plated copper base and ships with two Kaze Flex II 120 PWM fans. The cooler supports current CPU sockets including Intel LGA1700 and AMD AM5 and measures approximately 138 mm (W) x 128 mm (D) x 154 mm (H), with a 120 mm fan and a total rated airflow of about 114.89 m³/h (39.44 cfm).

Advantages

The asymmetrical twin-tower design increases fin density for improved heat dissipation while maintaining full RAM compatibility and reduced interference with the GPU. Two Kaze Flex II 120 PWM fans use sealed precision FDB bearings and rubberized anti-vibration pads to lower noise and vibration. The reverse airflow (fans rotating in opposite directions) raises static pressure and produces a stable, increased airflow. The H.P.M.S. V mounting system includes a pre-assembled bar and universal backplate for secure, balanced contact and straightforward installation on a wide range of sockets.

Suitable for

• Air cooling for mainstream and high-performance desktop CPUs
• Small form factor builds where RAM clearance and compact dimensions are required (Mini-ITX)
• Systems requiring quiet operation with reliable sealed FDB fans

How to use

Mount the Fuma 3 using the supplied H.P.M.S. V mounting system: fix the universal backplate to the motherboard with the rubberized spacers, position the pre-assembled mounting bar over the CPU, and tighten the spring-loaded screws evenly to achieve balanced contact pressure with the nickel-plated copper base. Attach the two 120 mm fans to the heatsinks in the provided positions, connect their PWM cables to the CPU fan header(s) on the motherboard, and configure fan curves in the BIOS or via software as required.

Recommendations

For optimal cooling and compatibility, verify available clearance above RAM modules and between the cooler and the GPU in your case before installation. Use the motherboard’s PWM control to set fan curves balancing noise and cooling performance; ensure the fans’ airflow direction matches the intended case airflow path.
