I just put together my own computer, with an Intel D865GLC motherboard and a Pentium 4 3GHz with HT technology. But one thing that’s bothering me is Intel Desktop Utilities tells me my CPU is at a temperature of 118F, and when I play games like half-life 2 it sometimes goes up to over 150 (over 60C). Is it overheating? I added an extra case fan but it doesn’t seem to help.
