alright I just built my first computer. I've been inside one before but this is the first time building from scratch. I actually posted on here awhile ago about a problem I had turned out to be a bad power button. Anyway got a replacement from newegg and built it all no problems. It turns on all fans start up except my cpu fan. it twitches a little as if it's about to start and then stops. what's the problem? I was under the impression that it ran nonstop even with a temp sensor on it (which I believe it has). Any suggestions?
