Proc at 58 degrees???

I installed speedfan in my server (low volume, idle most of the day) and it is showing ~58 degrees for the processor (Opteron 185 dual core).

A few minutes after boot it is down to ~52-53.

What is a healthy range for this? My other Opteron (dual 280 dual core procs) is more like the mid 40's.

There is a thermaltake cooler on the proc and the fins of the heat sink look like they have a lot of dust on them.

Thoughts?

You answered your own question. Dust acts as an insulator when on HS thus preventing it from doing its job.
If you are too lazy to

remove HS and clean it you could just remove fan and use a dust buster while its still mounted on CPU.

Dont forget to clean fan too, and while you are at it you could change TIM as well.
And yes, those are high temps, actually too high considering that your CPU is never @100% load.

Is cool'n'quiet enabled?

Blew some air through the heat sink last night and got the temps back down to ~48.

Can't use powernow because the BIOS is unstable with that enabled (Tyan 2865). That is a project for this weekend, again.

Try RMClock and ChrystalCPUID with relaxed timings. (RMClock: Advanced)

I think I finally found a way to get the right BIOS (3.03) running on this board so that I can support PowerNow.

Cleaning out the fan and running PowerNow (proc now varies between 1 and 2.6gHz) has really made an impact. The temperature is 39c ambient and 39c on the proc.

No more flame icons in speedfan.
