CPU temperature

I 'm using pc probe to measure the temperature of the Cpu.
I'm using cubase as a vst host (i have a second computer with Logic as a sequenser)
and the cpu performance is about 30 -40% (pent 3 800). The pulsar mixer when the surface is open "eats" alot of cpu performance and the temperature gets at 90 degrees which is my threshold in Pc probe-
what temperature is safe for the Cpu?

If this is degrees centigrade, it is way to much, check you heatsink/fan for correct seating and working. If its fahrenheit, don't worry.

Don't you know that those dsp cards do not use cpu power, they free the cpu of its burden, making is available for all other purpose! (sarcastic mode)

i ãm talking about the pentium - i have enough knowledge to use my pulsar-

Well i 'm using my pentium III for 1 year with a broken fan!
the temperature was always at 70-80 degrees celsium
But everything is working alright. I 'm going to change it tomorrow -
anyone knows if the processor is damaged due to overheating? how can i be sure?

This is an interesting thread.

What CPU coolers are you all using? Is there one that is clearly better than another? Does the use of thermal compound make a difference?

Anyone using RAM coolers? Anyone using water cooling? Anyone tried IC cooling on Pulsar/Scope (besides a fan)? If so does it make a difference in stability?

I'm using a Socket 478 IC btw.

If it is still working after all that time, it is most probably not damaged. But it can have an influence on the total lifetime of the cpu. Normally, the damage zone is around 90°C.

Now the older cpu's can stand heat better than the newer, due to being made with larger geometries.

As for coolers, always use them with some form of compound/grease or phase-change stuff. Otherwise it can be worse than no cooler. RAM coolers, don't know. My DDR run quite cool. And the sharks run also cool so why add coolers to them.

The only things that get extra cooling in my pc are the 10000 rpm scsiU160 disks. Just an extra fan blowing over them at low speed. This makes the difference from hot (>50°C) to case temp (low 30°C).

First of all. ram heatsinks are a scam! you totally do not need them.

as for temperature, the rule of thumb is at temperatures up to "burning out" for every 10degrees celcius operating temperature you loose 1/2 the life of the component.
P3s are designed to run nonstop for something like 12 years though, they will turn themselves off if they get too hot.

btw. if you suddenly start experiencing random craches and blue screens-of death, your processor might very well be burnt out.
I was building a pc for my brother from old components a while back and I just couldn't get the thing working without it craching constantly and I was on the verge of throwing it out the window, when I noticed that only one of the fans on the P2 was working which had burnt out the processor.

got the fan and the temperature is 45-54 degrees celsium-the pentium is Ok -(it have worked at 80 degrees for about a year!
