I searched everywhere and tryed everything from reversing the fan on the side to adding 2 fans to the heatsink and it screamed like a banshee because I was getting such high temps such as 51c idle/58c full load with prime95.... and I was like WTF i have the second best Heatsink on the market... then in the end... in the back...i reversed the 2 panaflo H1As in the back from being exhaust to being intakes and my CPU temps dropped from 51c idle/58c full load to 38c idle/45c full load... amazing a 13c temperature drop in idle mode and 13c temperature drop in full load mode.... also my case temps full load dropped from 33c to 24c... a 9c case temp drop....i also put my computer under the air conditioner in the ceiling... this is so the cool air gets blown down to the two intake fans..so for those people who are getting awfully high cpu and case temps try reversing the fans in the back and side...intake is more important i found out..this is because the cold air in the rear blows in and my cpu/heatsink/hs-fan is right there and it gets the cold air being blow in and swallows it.. that produces such low temps... my current fan setup is 1 Panaflo L1A 120mm intake/ 1 80mm Power Logic exhaust in side and top/ 2 Panaflo H1As intake in back
