My Coolermaster DP5-6h51 socket A fan stops blowing every 20-30 minutes for a few seconds. Temperatures rise during this phase. Is this just a crappy fan, or is there a reason for this? My 750 tbird is currently running at almost 60c, because I'm waiting on my case fans, but the processor fan seems like a problem anyway. Is there a way to stop it's moody behavior, or just go buy a Globalwin?
