CPU Temps seem high.

I have a gateway 6400 running 2 1 ghz PIII's. Sandra reports the CPU temps for both CPU's to be around 75 C. is that high? this is the first time i've even bothered to check temps on an intell processor and i'm not sure what normal is.

btw, ambient temp is 27 degrees.
 
That sounds very hot to me.

The Athlon XPs are considered hot running CPUs, and they usually run in the low 50s, sometimes up towards 60C under full load (with good, but air only, cooling my 2200+ runs between 47C and 51C depending upon load, which seems to basically mean how long it's been running 3D graphics - nothing else heats it up much).

Do you have at least 2 case fans - one blowing IN in the front and one blowing OUT in th back? Assuming it's some kind of a tower case, you want the front / intake fan to be positioned low and the back / exhaust fan positioned high (since heat rises). I'm also assuming that you have working HSFs (heat sink fan assemblies) on both CPUs? If they're passive cooling only (heat sinks, but no fans), that would make a huge difference.

And there's always the possibility that the PIIIs just run extremely hot... Another possibility is that you're getting a bogus reading. Does your BIOS support display of the CPU temp? Or any software that came with the motherboard?
 
yeti

check my ambient temp. air flow isn't the issue.

i think it's the internal thermister on the P3 vs the external one that most amd cpus read from.
 
Aye - your ambient is only a little bit high (just over 80F), but extra airflow could still help a bit.

You're right that the older AMDs did have external (motherboard mounted) thermistors to read the temperature, and they did read cooler than an on-chip thermistor, but the newer ones like mine are reading an on-chip.

You do have fans on those CPUs, right? You could pop them off, slap on some good thermal grease, and see if that helps a bit. First though I'd check the temperature some other ways if possible - such as with a different utility or from the BIOS. Also try upgrading your BIOS. Sometimes BIOS upgrades do a better job of reading voltages and temperatures and give more accurate readings.
 
yeti.

ya, i have alpha pals on both of them. should be more than sufficient.

i've been running them like this 24/7 for like 1 yr now. just checked temps for the first time yesterday, so they are probably ok.
