Following up on the success of Thermalright's immensely popular XP-120 and XP-90 the company's engineers were asked to go a step further and do for Socket 775 what Thermalright's fabulous twosome have already done for Intel's P4s and AMD's K8s.As both heatsinks already meet and surpass Intel's standards for Socket 775 cooling solutions Thermalright's engineers only needed to develop a two piece frame that would not only accommodate Thermalright's XP-120 and XP-90 heatsinks, but would be also able to negate any infringement of the no, no component zone around the socket itself.If you're one of those people, who may be concerned with the weight of the XP-120 and an accompanying 120mm fan (normally more than 150g); Thermalright has included its own metal backplate for additional support and to prevent any flexing of the motherboard due to the weight of your heatsink of choice.Your socket 775 CPU will thank you, with improved performance!
