Okay i have Intel Core i3-2100 Sandy Bridge @ 3.10GHz, it was in a computer i bought about 3 days ago. When i first got it the idle temps were i say cool around 30-32 on both cores now 1 core idles between 28-32 and the other is 36-40. Any ideas whats wrong or is it normal? It has the stock HSF. It literally just started happening, also i DIDN'T install the CPU. If you guys need more specs just ask. Just curious on whats going on also if it needs it i don't have time to re apply thermal paste also i never done it before.
