The EKL 22225 consists of an extrusion profile and reliably dissipates heat from your processor. With a compact height of just 55 mm, this cooler is ideal for all compact PC systems, workstations or even normal office PCs. The built-in fan has a 4-pin connection and can therefore be controlled manually via the mainboard. This enables an adjustable speed range of 500 - 2200 rpm. Thanks to the existing PWM signal, the fan operates depending on the utilisation of the CPU.
