I have built a new micro atx system using an Apevia micro atx case, a 550w power supply, amd fx-6100 6 core cpu, an asus m5a88-m mobo. and 4gb of ram..I have it oc'ed to 4ghz right now and decided to run prime last night..Prime has been woke up this morning expecting my system to have rebooted, but surprisingly prime is still running !!!!! Using cpuid and the mobos on monitoring software, its showing temps have gotten to the high 70's(celsius)..don't know whats the safe limit for the fx series cpus is, but was wondering if I put in the H60 water cooler would my temps be lower.??? Right now I'm using an old heatsink/fan I pulled from a system I built over 2 years-heck I didnt even see a brand on it..If you dont think temps would drop any, i will just leave it the way it is because i would have to modify the case to put in the H60 anyway(wouldnt be too hard though)
