I have a overheating problem on my i7 on idle its 50 degrees and ounder heavy load it is 90 degrees and i have not even overclocked it. Before i changed the thermal phaste it was 100 degrees but 90 is still a way too much my brother has the same build and his cpu is maximum 69. can i somehow fix this problem or should i just buy a better cooling system. Me and my brother have the intel heat sink we got with it. !!! PLEASE HELP!!!
