Ai chihuahua, how hot, to say it needs an aftermarket cooler is a slight understatement, i know they run hot but jeebus.When the core voltage was improved to 1.2V, Core i5-750 can achieve 3.6GHz (200MHz*18), but the core temperature was around 90℃, so this is not ideal for a long-term run. It’s essential for overclockers to change for the third-party cooler.
