360° View - Asus Silent Knight II Information on Frostytech's test methodology is available here.
The 25x92x92mm fan is illuminated with a pair of blue LEDs. Power is supplied by a 4-pin motherboard fan header. The Asus Silent Knight II heatsink stands 140mm tall, so it should easily fit within most computer cases. If you're not careful it's easy for the fan cable to get tangled in the impeller, so watch out for that when installing the Silent Knight II.
Two 40mm wide sections of cooling fin form the basis of the Asus Silent Knight II heatsink. With the 92mm PWM fan set in between, both intake and exhaust airflow is put to use cooling the processor. The six copper heatpipes are 6mm in diameter, and soldered at the joint and base plate. The base is 4mm thick copper. Each copper fin is 0.15mm thick and spaced 4mm apart at its widest.
The copper base plate measures 38x39mm in size. It has a smooth sanded texture that is generally flat in both axis. The bulk of the Asus Silent Knight II heatsink is 45m above the base, so there is some clearance for adjacent motherboard components.
