I just completed a computer build recently using the AM2 socket MSI K9N Neo-F motherboard and 5000+ X2 processor. The cpu installed fine, but the cooler was extremely hard to clip on both sides, and then i couldn't flip the lever. it seemed to be on there pretty solid, as i couldn't move it. Also, the motherboard looked like it was bending in the middle, which scared me a little bit. The computer runs fine, but the cpu idles at 40 C (core temp). Is this normal? Should I upgrade the cpu fan, and if I do, how would I get the stock fan off?
