I just overclocked my CPU a little bit for the first time last night. I'm running a Pentium 4 (Northwood) 3.0GHz and i have it oc'd to 3.46GHz. I'm using the stock heatsink/fan but it actually seems like a decent (maybe not by your guys' standards lol) heatsink as it has a copper core that contacts the CPU and then it spreads out to the dome-shaped aluminum fins. The processor is known to run hot and it always has for me, but now that I have the sucker overclocked, it seems to idle from about 52-56C and when I put a load on it (Counter-Strike: Source), it seems to go up to about 68-73C. Is this too hot for the CPU, even if it does run hot? As I said before, I'm pretty sure the these temperatures weren't much lower even without overclocking.
