Hello people of Techspot. As per title, I could really do with some advice regarding my CPU temps. To cut a long story short, I changed back to my NZXT case as the CPU fan (which is screwed in) on my Dell case failed last night. But I just can't get the CPU temps to reduce! I've now tried reseating (and new thermal paste) 3 times, and it seems seated, but just installing ATi drivers for example (pic below) is shooting my CPU temps to almost 100'C. Its idling around 50-60'C, and shooting up at the slightest load on the CPU. Its not thermally throttling though, even when its registering 100'C its still running at maximum speed. I'm using the standard LGA775 Intel fan, and my CPU is a Q8300 core2quad. I'm using HWMonitor for temps, which seems pretty accurate - My BIOS doesn't show me my CPU temps anywhere either, so I can't check them. Everything is the same, except for the new case, and 3 additional fans (2 side, 1 rear, 1 front), so I don't see how that would cause it as airflow should be perfect! Surely its got to be a badly fitting stupid heatsink, or could it be anything else?
