Subject: P4 CPU Temperature: 50-77C

I'm running on a Pentium 4, 3.0GHz CPU with some sort of ASUS mobo.

My fan started making different noises, so I downloaded Motherboard Monitor 5. It claims (claims supported by BIOS temperature readings) that my CPU runs upwards of 65 degrees. When I push CPU usage to 100%, the temperature rises to around 67C (though I've seen it run beyond, into mid-70s).

Intel's official site quotes that 45C is pretty hot, life-shorteningly hot. That's about where my CPU sits when idle, 40-45C.

However, the article on this site says that the max varies from 65-78 based on CPU type, and that the CPU slows down automatically as it overheats.

Should I be worried? I only have one fan other then the CPU fan; I'm trying to get a second...

about 45C being too hot - are you sure you haven't confused case temperature with CPU temperature here?

Still, mid-70s might be too high for your CPU. See for more detailed information about the maxium temperature for your specific CPU model.

Not sure which CPU I have ...

Confirmed, Motherboard Monitor labels the CPU temperature sensor as "CPU" (I've verified that it is correct through my BIOS as well). I run my CPU hard (game development), so I need it cool, I don't want my CPU dying in a few months.

It might be possible that my fan is damaged, as well, but I'm not sure how to tell.

Turns out my CPU fan was extremely clogged and virtually non-functional. I added an extra fan as well, which brought my CPU temperature down to about 46 at 100% CPU usage.

Awesome. Thanks guys.
