Acceptable CPU temp?

Hi,

I've been experiencing random spontaneous reboots for some time now, and I'm
trying to eliminate problems one at a time.

I'm using an AN78 Deluxe rev 2.0 board, with and Atlhon XP2800+, 2x512Mb of
Crucial PC3200 Ram and 7 hard disks.

Obviously this generates a fair amount of heat, but I have two case fans at
the front blowing air in, two at the back drawing air out and 4 fans on the
PSU. I'm using the Silverado CPU cooler and fan.

Checking the BIOS gives a CPU temperature of around 59 degrees C. Is this
too hot? Could that be the cause of my problems?

Any other advice appreciated.

Dan.

If using thermal paste I'd re-do it, after my 3rd try of putting paste
on my Barton 3200+ the die temp dropped 10C, I was either putting too
much paste on or the HS wasn't really sitting flat on the CPU, not sure,
but whatever I did it runs a lot cooler. :)

Motherboard Monitor can read the cpu die temp on the A7N8X/A7N8X Dlx in
windows and log the data to a file. If CPU die temp is hitting 70C or
more under load then I'd say you need to re-do/fix your CPU cooling
setup. I've seen my die temp hit 65C (before I redid paste), but it
never crashed.

7 hard discs, hope you have a big enough PSU. :)

Dan,

At the risk of sounding like a stoopid Intel guy, those temps shouldn't even
take a P4 down as they (generally) hit the wall somewhere around 70C. I've
read that the XP2800 flakes and reboots only at about 80C.

That said, having a case that breathes well along with a good cooler and
fresh cleaning and reapp of artic silver are a big help.

I would expect that chip to idle somewhere mid to upper 40's.....sounds like
it needs air.

Oh, interesting. Will have a look at that, ta.

470W, four cooling fans on the PSU :-)

Well that's what I thought. Leaves Windows as the prime suspect. Again.

Hmm, perhaps I'll get another CPU fan. I have four case fans already. Any
more and the sodding thing is going to take off!
 
I recently had an A7N8X with 2800+ that started doing this.
Also had some other things start to go wrong (ethernet
wouldn't work at full speed, some other things got flaky).

Fixed it by simply cleaning the accumulated dust off the
motherboard. I had a Volcano 9 blowing pretty hard
and it caused a lot of dust to adhere to the board. All
problems went away when cleaned.

You temps, by the way, while higher than average, are
not a problem. My 2800+ ran at about 60C, 70C under
load for a year with only the above problem (and it was
overclocked). If not oc'ing, it should stay stable to 85C.

Yes, that's too hot for a CPU. AND, what size and brand of power supply
unit are you using to run all that hardware???

Dan,

I know the feeling. Recently moved my modest rig (P4 2.0A in an Antec SX830
case) upstairs where idle temps were running 34-36C (high for this machine)
and neared 50C after gaming for short periods.

I snapped in another (2) 80mm fans and brought the temps down 4-6C.

I now have (4) 80mm's, 2 front and 2 rear, the fanned display adapter, and a
5200rpm AVC cooler on the chip.

Keep small animals and children away from the front bezel :)

470W Super Flower 4 fan PSU.

To be honest, I don't think the PSU is the problem. Until recently I used to
have a 350W in there and now that I have fitted the bigger PSU it's not
crashing any less.

I think CPU temp may be the way to go. I noticed that ever since I
uninstalled the United Devices grid computing screensaver (the one that uses
100% of your CPU when it runs), it's more stable, but it's still not
perfect.

My P4 2.8 runs quite happily full bore at ~60 degrees C (usually around 53
but it is getting warmer in the Great White North). However I did run into
problems as my hard drives were running hot.....They were stacked on top of
each other, had a case fan drawing air over top of them, but eventually they
got so hot I was getting random lock-ups, no boots, file errors, etc. So hot
even the plastic cover on the bottom was scorched. Too hot to touch.
You say you have 7. Are they stacked on top of each other? I mounted a hard
drive cooler to the bottom of each. Something like:

They seem a lot happier now.
