"The SilenX brand is most commonly known for their cool and quiet case fans. SilenX, however, does manufacture heatsinks, power supplies, and other goodies. Today SilenX gave us the opportunity to review the SilenX iXtrema IXC-120HA2 Pro Series Heatsink. This vertical fin stack design offers plenty one of SilenX's very own case fans, we actually got two to test out. The features include a fan speed controller, exposed copper heatpipes on the base, and an entirely screw-less design making for an easy and tool-less installation."
