Maximum Temp for P3 800EB stemping cC0

[petepham]

I recently bought a P3 800EB using the intel supplied heat sink fan. It failed after a couple of days without my knowledge and after heavy CPU usage, the CPU temperature ran up to 64 C where my BIOS shutdown the CPU (I set autoshutdown at this temp). My CPU was running hot (about 40 C) for less than 20 minutes and reached a max of 64 C for only a few mins. I want to ask and see if there would be any long term damage to my CPU or and performance degredation due to an exposure to this high temp. Any help would be appreciated thanks!!!!

Slot or Socket P3?

What heatsink are you using?

What MB and what is your ambient case temp?

I am using P3 Socket 370 800EB cC0 with the retail boxed intel cpu fan and Gigabyte 6VX7-4X+. I don't know how this will help, but i was just curious if my CPU could have sustained permanant damage or performance degredation.

It could potentially.... Do you know your ambient case temp or mb temp?

You might want to also change fans/use thermal grease.

Potephan,

You are really running close to the limit when the P3 runs at 64 C. The absolute limit for for 800EB is 80 C. If you are overclocking, the max temperature should be lower. For example, 1 GHz P3 has a spec of max die tempterature of 70 C. Intel is already overclocking these CPUs, so there is not all that much room for the customers.

To get the thermal specs of Intel CPUs, refer to PDF document that can be downloaded from here:
ftp://download.intel.com/design/PentiumIII/datashts/24526407.pdf
Page 47 of the PDF.

You will notice that the current generation of P3 CPUs are very fragile, with the allowable temperature not leaving much room for error. I wouldn't touch anything over 866 MHz myself, which still allows up to 80 C.

Just for comparison, Athlon CPUs are much more robust, allowing the max die temperature of 90 C, with the latest revision allowing all the way to 95 C.

I am sorry for the confusion. I meant that THE CPU FAN FAILED causing my CPU to run up to 64 C during heavy usage. At this point, the BIOS shutdown the system. Since the CPU FAN STOPPED, my CPU was running hot (about 45-50 C) for less than 20 minutes and reached a max of 64 C for only a few mins. I want to ask and see if there would be any long term damage to my CPU or any performance degredation due to an exposure to this high temp.

I don't think there should be any long term damage if it ran at 64 C for only few minutes. I was under the impression that it was your normal operating temperature, which would be way too high for P3, and over time could cause damage.

Oohhhh!!!

Okay, for a few minutes you're okay... I think p3 max sustained temp is probably in the 50C range.

petepham,since you boughtt the cpu retail & the fan failed, then I suggest you get it replaced(cpu &hsf) under Intel's 3 year warranty for retail boxed cpus!
