This isn't my first system build, but it's my first one in 3 years. I've got a i7 920 (D0) with stock cooling. I initially used the factory thermal paste, but was getting even higher temps. I just applied Arctic Silver 5 (using their instructions) and i'm still getting temps I consider pretty high compared to all my AMD builds in the past. I'm using a GB UD3R Mobo and my case is an Antec P180 which has pretty good airflow over the CPU. I'm worried I've got a crap CPU? can I exchange it at Microcenter worse case scenario? any suggestions? Thanks! -Bryan p.s. I'm using Real Temp 3.00 to monitor the temp.
