I haven't overclocked the CPU at all, I think when i had first gotten the computer it was running 40 degrees Celsius idle, and 50-60 load, i didn't mess with voltages. it's completely stock. I bought my computer from Ibuypower and yesterday was my first time opening it since i had gotten it in 2010. I had cleaned the stuff off with alcohol then reapplied it. It's either my water cooler is getting old or i applied the heat-sink wrong i think those are the only two possibilities. Another possibility is that I didn't place the attachment good enough on the CPU for good contact but i don't' think that's the case, i didn't take out the CPU when i cleaned it. I had just tried my game now and its hitting 95 degrees to 100 degrees back and forth on all cores with multicore rendering active. with that option clicked off it hits 90 max.
