I have the problem. Before LCS I had TT Big Typhun which blew that around CPU socket area. I had the folowing max temps: SB 45, NB 50, POWER 36.
After installing LCS I became totally unstable: Linpack, MemTest 3,8, Prime95 gave me errors. Max temps are: SB 51, NB 56, POWER 45. I don`t think +6 degrees to SB and NB make my system unstable. But what about +9 degrees of POWER ? Even IntelBurnTest gives me errors.
To check this, I put fan over motherboard. And now i`m stable. But i don`t want to use additional fan .

So, what do I need? Swiftech MCW-NBMAX or waterblock on top mosfet? or both?
