Setup: MSI 770-C45 Mobo Thermaltake Extreme Spirit II with 2 small neoprene rubber washers as balance for contact AMD Phenom II X4 810 w/ stock cooler Diamon ATI Radeon 4890 Corsair CMX DDR3 1333 4gigs Windows XP SP3 250 WesternD HD Thermaltake 600w PSU Cheapy Apevia computer case w/ 4 antec 80mm fans for intake and 1 antec 120mm exhaust So i've been researching and people have their Northbridge temperature at like 30c-38c- degrees on idle and 45c on full load. That's not reality for me though haha. My Northbridge goes from 46c idle to 52c on full load! And thats with the Thermaltake Extreme Spirit II Northbridge cooler installed. I made sure that the cooler comes in contact w/ the thermal paste on the chipset so I can't determine the problem myself. I know for sure after I post this thread though, i'm going to further tighten the cooler just a tad bit to see if that helps. I hope you guys can give me some insight on how to lower my Northbridge temperatures. I don't know if this is important information but the CPU runs around the same temperature as the NB and sometimes even more to about the 54c range. Please help me guys.
