Optimal Cooling Output for socket AM4

EKL Super Silent SI consists of an extrusion profile and dissipates the heat of your processor ideally and reliably. Having a compact height of just 60mm this cooler is ideally suited for any compact PC systems, work stations and also for the common office PC.




Almost Inaudible

The mounted PWM cooler is supplied with a 4-pin connection and so can be controlled via the mainboard. This allows a regulated rpm range of 700 - 1600 rpm. Because of the existing PWM signal the fan acts according to the respective CPU processing load.

Additionally, the fan has a hydraulic bearing with a service life (L10) of more than 25.000 hours.
