I recently bought a new motherboard for my P4 1.6GHz. I fried the motherboard it was in bfore and I tried it in the new motherboard I bought and it worked. On to the point, the temperature for my CPU is about 19 Degrees Celsius, System is about 26. Theres also a system case fan in it. It says its at 19 Degrees but when I change the CPU Ratio to 13.0x and CPU/DRAM Speed to 133/133 the temperature goes all the way up to 79 degrees celsius and it was barely on for 20 seconds with the settings like that. Any ideas on y??
