Software stress testing Hardware?

I found glxgears will consume one entire core 100% per copy running. Running two copies for a good length of time produces a temp of 50c. Right now I am running three instances of glxgears and seeing a temp of 54.5c to 55c that is at 89% to 90% of the CPU according to “system monitor”. “Supposedly” the CPU is supposed to throttle itself back if it is too hot.There is no way I would count on that though.

My test that I settled on was running eight copies of hina.swf at the same time CPU got up to 57c. As AMD says 62c max I am OK with the stock Heat Sink. My actual top temp has been around 47c. Usually it runs around 37c to 39c. The ambient temp in here is around 26c max so I am safe with the Heat Sink I have.

The unixbnech script has one test it runs where it runs 16 scripts at once. That is the only test that comes anywhere close to loading the CPU 100% on all 4 cores. I got some insane Dhrystone number. I remember using a VAX 11/780 system and it seems fast at the time. Now it would seems slow.

Isn’t that one of the very first VAXes from the late 70s? I suspect
even a 486DX2 would be running rings around it.

That is what one Dhrystone equals the computing power of a 11/780.
That was a later machine.

I forgot to add this bit I found that easily made my CPU run 89% to 90%. I rant three instances of glxgears which managed to use three cores at 100% and heat the CPU right up.

This left me wondering if “cool and quiet” CPU throttling or safe thermal shutdown was well implemented and active on my install. I nver got close to 62c and my BIOS is set to shut the system down at 60c.
