Linux – ATI Temperature Monitoring

I've heard it stated that you don't want to get your GPU above 70 degrees Celsius or so, and that even in the 60s you're starting to push it. At that point, you may start to do damage to the card itself. I don't know about minimum temps but the 40s are fine for operating temperatures.

I would start re-evaluating my cooling strategy if I'm going over mid-60s regularly.

Having it up in the 90s is out of the picture. That's way too high of a temperature to be considered safe. You'll likely cause permanent damage or shorten the life of the card with such high temps.

I had to do two things to monitor my FX8350: Turn on IOMMU in my BIOS and load the it87 module.

I have an Asus board, and it has the IOMMU options in the BIOS under Advanced --> Northbridge, I believe.

sudo modprobe it87 should take care of the rest. Of course, you'll want to add a line to /etc/modules, so it87 will load on boot. If you run sudo sensors-detect it will offer to add the option to /etc/modules for you.
