I actually think to stop cracking.....

But, I am asking myself if it's my heatsink/fan setup.....

The fact is that I personnally put the heatsink compound on the heatsink's base and it wasn't that easy. At work, when testing larger heatsink for electric motor, I had to apply thermal grease and the grease was easy to apply in thin coat. But with my CPU heatsink it is another story...

The thermal grease is coming from Krex computer (they sold it with heatsink) and has a granular texture and is more gray than white. (I was thinking that all thermal grease were white...)

So, when I tried to put a thin coat of thermal grease on my heatsink I had a bad surprise : it was almost impossible...I know that too much thermal grease is not good so I had to make a non uniform thin coat of thermal grease....

And the result is 17 celsius iddle and 71 celsius when cracking RC5. And my probe is supposed to be up to date : a cubx with ASUS probe v2.11...

Anyone have any idea to reduce this...the max Tcore from Intel web site for a PIII850Mhz is 80 celsius...I dont want to fry my hole new CPU...

Thanks for your help

I know that this may sound silly but have you installed your hsf correctly? it may be on the wrong way! (I'm assuming that the fan is working!)

The latest version of Asus probe is 2.12.09. You can get the latest version from Asus' website, or from here. Do you have the latest version of the CUBX bios? Is the heatsink sitting flush with the cpu?

RC5 doesn't do anything special, it just runs your processor at full load. Thus, UT or Q3A or other processor demanding software will also cause it to run around 71 C (if that's correct). I think you'll need to do more than just stop RC5 if the temperature is correct. :)

bacillus, the fan was already mounted on the hsf and there is only 1 way to install a hsf on a socket 370, i guess. And the fan is working :)

Smbu, I also have a PIII700 socket 370 with a hsf and the difference with the 2 is that the one with the 700 has a kind of slot for the cpu core so that the heatsink can touch both cpu core and the rest of the processor unit and the one for the 850 dont have this "slot" so there is only the cpu core that can touch the heatsink.

I will dl both asus probe latest version and CUBX bios...

Does anyone have a PIII850 so I can compare these data ?

Thanks again guys

[Edit] Also , when I look at the data with asus probe, the temperature is going from 17 to 71 almost instantaneously and when I close RC5 the temperature is going back to 17 is less than 5 seconds.... [/Edit]

Since you're getting a fast-drop from 71C to 17C and the corresponding fast-rise it would appear that one of 2 problems are happening:

A) The heatsink is not making good contact with the CPU. This could be due to too much grease, heatsink not made for flipchip socket-370, or any other number or issues. It could also be that the heatsink isn't good enough for your CPU.

B) The CUBX may have problematic temp reading. Have you tried Motherboard Monitor?

First, the problem is probably solved....I removed the heatsink and put new thermal grease (twice the quantity I had) and now the load temperature is 50 C.

Also, I flashed my bios to revision 1006.

Then I tried to install asus probe latest version but with no success in both WinNT40 and in Win2k...

Now, I will try to install motherboard monitor to see what is happening with my cpu temperature.

Is 50C too much, BTW ?

50C seems a little high since my 700@980 @ 1.75v rarely goes above the low 40s under full load with a cheap Coolermaster heatsink (same thing with a Gorb).

I will try to reinstall it ASAP and I will try to find a better hsf....

Thanks for the info guys
