i help my fren build a rig. using Thor's Hammer pair with E8400, i clocked it at 9x450=4050mhz 1.26vcore. when i use linx to test the system stability. cpu temperature went up to 87c (non-aircon room). i double checked the cooler , installed correctly. but when stress with linx , i touch the heat pipe of thor hammer, didnt feel hot at all,but when stop stressing ,after 30 second went back to 40c, is this consider normal?
