Hello, I notice the following with my computer temps: I installed ATI 850XT. When computer is idle, CPU temps are low at 86F, and 91F for the motherboard. After gaming CPU temps increase to 125F and motherboard goes no higher than 95F Im using stock heatsink. But I took off that thermal crap they give you and I applied Artic Silver 5. I applied the thinnest sheet I could without ridges and valleys. Depending on the room temperature. I have seen the temps during gaming go as low as 115F. But when people in the house are cooking and the room heats up, the temps can get as high as 130F during gaming. The temps are similar in both the BIOS and the ASUS Probe application. My CPU is a pentium 4 3.0ghz 800fsb 512L2 cache The video card is the 850xt from ATI. I have one nice sized fan blowing in from the front, one blowing in from the side, one blowing out from the PCI slot, and one blowing out standing over the CPU next to the video card. Are these temps normal , and do I have anything to worry about? I invested alot of money in installing good parts in the box. Last thing I want is anything to be damaged because of heating. I notice the CPU fan speed stays at 2700 RPM and doesn't move even when gaming. I think that should go higher than that. I checked out QFan control in the bios and toggled it to see what would happen, no cigar. Any ideas are appreciated. Thanks.

When running games, 130F is nothing to be concerned about. Also P4s are protected with an internal thermometer switch that will stop the CPU is it gets too hot.

Is your processor prescott? or Northwood? prescott processors are known to heatup, stock heatsink doesnt seem to cut it. So id go with a new heatsink for sure, preferably the XP-120 and 120mm Fan, which so far ive read on forums is the best cooling heatsink for 3ghz+ prescott processors.
