Is this a safe temp to run a Celeron 800 at?

[Tom Langton]

I have a Celeron 800@952 and I'm wondering wether 31-34 deg C is a safe idle temperature. These temperatures were recorded by the Sandra utility. I would also like to know how much of a temperature increase running it at full load would be. If it runs at 34 deg C idle would it run at over 45 deg C under a full load?

idle temps are worthless. Load temps are what matters. Run a good stress program like Prime95, Seti, Folding, Sisoft burn-in and take a temperature reading then. You are not going to damage the chip, it will crash before that happens and according to tom you can pull the heatsink off the chip and its ok.

Idle is not important as William said as its very common for everyone to get idle temps of 25-30...

Load temps are what overclockers to look for as they compare that temp to the dangerzone.

Download what William stated and download Motherboard Monitor, setup all the sensors.

The temperature you end up after about 1 hour is your full load temperature.

45-50 is what you aim for.

50+ is a danger zone.

So can a check the temperature while running the burn in program in sisoft? Or do I just check the temperture after running it?

[Yodums]

You let it run for about an hour and check the temperature after an hour while its still running.

Thanks. Sorry for being such a newbie but I thought I should ask, just to make sure I was getting the right temperture reading.

I have a similiar setup an personally don't like seeing temps in the 40's ever. I guess I would be coming close if it weren't for a couple of case fans and a alpha. But with my cel 800@1.2 gig i get full loads max temps of 28-29 range never at the 30 but I got a sweet cpu. Ways to help drop the temp I have found that for starters with what you already have availible try lapping the heatsink with finnishing paper or the finest sand paper. Then use the scotch tape trick to put on your paste. that tape trick dropped my cpu on my old rig a good 2-3 degrees seems too much or to little and uneven can affect temps. As for your load temps jumping say 32 idle to like 45 thats quite a leap so it sounds like you need to get some of that hot air out of your case.What is the sspecs of your 800?

I missed something. "Scotch tape trick?" Could ya let me know where to look? I'll do the work. Thanks.

OK, here's what you do. Take two pieces of Scotch tape long enough to fit across your heatsink, and put them on two edges opposite each other (I'd recommend you use 4 and put one piece on every edge of your heatsink). Then, put some Arctic Silver or whatever interface compound you use in the middle of the heatsink. Find a straightedge, something stong enough to spread your compound (a scrap piece of cardboard works nicely), then run it across your heatsink in a pattern in which it will evenly distribute the interface compound, making sure that the edges never leave contact with the tape. This should distribute the compound into a layer about the same as the thickness of the tape, which is the optimal thickness of the compound.

If you use this method, it'll ensure that you have enough thermal compound to cover any roughnesses in the CPU core or the heatsink material, but not so much that it keeps heat from conducting well. Hope this helps.

If you get MBM you set it up to put the temps on the bottum of your screen all the time

Jazztrumpet216-thanks, bud. I have to laugh at myself sometimes. I always think about how to get an even thickness on the sink. At the right thickness. The trick is perfect. "why didn't I think of that?" It's the old "2 heads" deals. ) Rooster_cruiser, I've tried every monitor software I could find when I was putting my sensor together and MBM was the one I chose. Worked best for me. Had features that are important to me. I have it on all my boxes tied in with "Shutdown." Thanks for the replies.
