To begin with I have a big *** 120V case fan in front 176mm mucho flow in. temps in the thirtys no problems OK problem. The position of psu in case is direcjly above proc sock, now this is snug fit enermax internal fan draws air away from proc while HSF fan trys to go the other way this didnt seem to efect temps too much till BA fan in front DIED!!??!! IDLE was 30-31c now with no BA fan Idle is 36-38c arghhh BTW HS is lapped ASilver is applied. Should i turn HSF around to draw air instead of fighting PSU fan Getting new BA fan today HOPEFULLY?????????
