Low-profile 54 mm cooler for small AMD builds

The Silverstone SST-KR01 stands 54 mm tall and fits AMD Socket AM4, AM3, AM2, FM2 and FM1 platforms. Two 6 mm copper heat-pipes and aluminium fins move heat into a horizontal 80 mm PWM fan. It targets compact systems that need a capable air cooler within a slim chassis.

95 W TDP ceiling without extra case airflow

The cooler is rated for CPUs up to 95 W when the case supplies efficient airflow; above that figure additional ventilation is required. The 800 to 3,000 RPM PWM fan delivers up to 34.33 CFM at a maximum of 33 dBA, so thermal headroom depends on how well the enclosure exhausts the warm air.

Horizontal fan mount needs RAM and VRM clearance

The fan sits horizontally over the heatsink, so tall memory modules or bulky VRM heatsinks can block installation. Dual ball bearings give the fan a long service life, but the 80 x 80 x 15 mm frame leaves little room for error. Builders should verify motherboard layout before fitting the unit.

Questions about this item

Which CPU sockets does the SST-KR01 support?

The cooler mounts on AMD Socket AM4, AM3, AM2, FM2 and FM1 platforms.

What does the 34.33 CFM maximum airflow mean for my build?

At full 3000 RPM the 80 mm fan moves 34.33 CFM, enough for CPUs up to 95 W in a case with good airflow.

How does the 800–3000 RPM PWM range affect noise and cooling?

PWM control lets the fan spin from 800 RPM for quiet idle up to 3000 RPM for peak load, topping out at 33 dBA.
