Thermalright Ultra-120 Low Noise Heatsink

The tower-sized Ultra-120 heatsink is sold without a fan, and is intended to be used with 120mm fans. Virtually all Thermalright heatsinks are sold without fans, so in effect the company is allowing the end-user to make the heatsink as quiet or as loud as they wish by incorporating a suitable fan for their personal noise requirements. Anti-vibration rubber strips are used along the leading edges of the fins to prevent vibration noises from occurring where the fan and heatsink meet. The Ultra-120 heatsink design is based upon copper heatpipes, a large array of aluminum fins and a small copper base plate; all of which have been nickel plated and soldered together. The Ultra-120 heatsink weighs 745grams without a fan installed and retails for in the region of $55CDN ($48USD).
