Phenomenal cooling perfomance for AM4 processors

The EKL Super Silent SI consists of an extrusion profile and dissipates the heat of your processor ideally and reliably. With a compact height of only 60mm, this cooler is ideal for all compact PC systems, workstations or even for the common office PC.




Almost inaudibly quiet

The mounted PWM fan has a 4-pin connection and can thus be controlled via the mainboard. This enables an adjustable speed range of 700 - 1600 rpm. Thanks to the existing PWM signal, the fan acts according to the load of the CPU.

In addition, the fan has a hydraulic bearing with a life expectancy (L10) of over 25,000 hours.
