A quick way to test for your Min/Max CPU operating temps.

[HAL9000]

I installed the Asus probe on my bench machine today, mainly because I have never really looked at the software. A quick peek at the CPU temp saw it running at 54'C which I thought, kinda high, but it's also not an overly large heat sink that I'm running on it. Then it hit me, the RC5-64 client was running which means the CPU is running at 100% capacity. So I paused the client and within 10 seconds, the temp had dropped to 35'C. Started it up again, and once again, the temp popped up to a steady 54'C.

So there you go, install the RC5-64 client from distributed.net and get your min/max operating temps in less than 30 seconds.

Nice tip Hal... my maximum temp has hit 40c running "UD" (Cancer Research) on a hot day, 36c at the moment, its a cooler day today.

Normal idle temp is 27c. Don't you just love them "HedgeHog" HSF's. :D

[HAL9000]

I can't say that I've ever tried one of those heatsink/fans, but looking at your temps, it's obviously doing a fine job!

[muckshifter]

I can't fault it Hal, I was getting temps around 55c with "UD" running and I just had to get 'em down. :D

It is one of the all copper types, got it from Overclock.UK, well worth £46.

I wonder if I can get my temp a little bit lower.just surfing the net my cpu is at 38c / 100f plus when gaming it get much hotter . I am using a heavy duty HS and ball bearing fan any suggestions .

[HAL9000]

38'C for an idle temp is fine, I wouldn't be concerned about it. I just have the standard Intel HS/Fan on my PIII 800E and running full load it's sitting at the 50'C mark.

Ok i feel better, but can we run cooler yet.iam just curious is too how cold i can keep it since i do game for houres at a time.check out the link and let me if thare is a better heatsink and fan
thanks ....bob

Ok i did some research ,and i ordered a Vantec FCE-62540D heatsink and fan & Arctic Silver II compound. hopefully this will make temps lower when gamming.

[HAL9000]

Couldn't hurt anyway :D

HAL9000- did you get your temp down at all.when I use probe I noticed if you disable fan control it runs a little cooler.i think the fans are running at max all the time when its off.two of my case fans have thermal sensors on them and I am not sure how or if fan control affects them

[HAL9000]

I wasn't concerned about the max temp as this was only on my bench machine at work which gets dismantled continuously. Under a full load, while 54'C may be hot, it's not so hot that I'm going to be concerned about it. If it were running 54'C while idle, or under a light load, then I would be concerned, but since it is 100% load, it's not going to get any hotter. My home machines which are using QDI boards show a max temp of about 51'C. Again, I'm not really concerned. Should the day come that I wish to crank these processors up, then I will chase down some Arctic Silver and some heat sinks that fit (there are some capacitors closer to the socket that they really should be).

Ok now that I reread every thing over again I under stand what your saying about max tempatures.Its a test you ran . what's the maximum themperature for a copper mine 1 Ghz with out frying it.i looked up the RC5-64 at distributed .net
but could not find the download for it not unless I over looked it.could you leave a link please.

[HAL9000]

Intel processors can take a LOT of abuse without frying. I forgot to plug in the fan on a Celeron 733Mhz at work and ran it in excess of 84'C for a week with no noticable harm to the CPU. I would have to look it up again, but I do believe that both Intel and AMD list critical temperatures at 90'C. 50'C and below is just a nice place to shoot for and leave plenty of margin so not to bake a CPU. The distributed client does a good job of working your CPU to the max, so you know you're within safe limits.

I agree. I was running an Intel Celeron 366 with a Peltier Unit on it. However the peltier unit died, and I didn't know it for about a month. I effectively had a big block of ceramic on top of a warm processor for a month. No wonder it wouldn't overclock stably for the longest time. Works like a charm with it's partner in my BP6 both at 550 after all that. :)
