It's been a while since I had a good old mess around inside my PC. But I thought I'd check today how hot the CPU is getting and it was getting up to 78c on full load! (using prime95) The safe temp is 62c, according to AMD. The HSF I'm using is a Cooler Master Hyper TX-2 and I'm running at stock values, not overclocked at all. So, I took the side off, vacuumed all the dust off everything, cleaned the CPU and heatsink with TIM cleaner, re-applied MX-4 paste, re-seated HSF and tidied up the wiring as best I could to get better airflow. I've even undervolted the CPU in BIOS! (1.264v now, according to CPU-Z) But the best I'm getting is 35-40c idle and then it hovers around 61c at full load, still far to high for my liking. Is it likely that the cooler here is to blame? I was thinking of getting an Arctic Cooling A30 to see if that helps but would like any advice before I shell out another £25!
