SilenX EFZ-120HA4 Heatsink Review

The SilenX EFZ-120HA4 heatsink is a full tower cooler, standing 151mm tall and weighing 836 grams. It ships with a single non-PWM 120mm SilenX 'Effizio Series Quiet Fan' mounted to the aluminum fin tower with four rubber vibration absorbing posts. The fan rotates at 800-2000RPM and as is common to this heatsink style, barely fits in place because the company holding the original design credit for this heatsink messed up its dimensions. The fin tower is about 15mm too short to properly mount a 120mm fan. It's oversight we'll talk about in greater detail momentarily.
