I have a Radeon Pro WX 5100 GPU, which is running at near enough full load. Here is a sample line from /usr/sbin/radeontop:

gpu 85.83%, ee 0.00%, vgt 0.00%, ta 85.00%, sx 0.00%, sh 0.00%, spi 85.83%, sc 0.00%, pa 0.00%, db 0.83%, cb 0.83%, vram 15.32% 1251.52mb

Is it possible to throttle the load on the GPU to reduce the heat? It's running at 84C, which is not excessive in itself but the case fans don't like it. I've seen threads on sharing the GPU between two tasks, but I want the converse.

This is a Gentoo Linux box - not windows!

Not that I know of. GPUs are designed to display output in real time so there's no type of way to run at 50% all the time. You can only run at 100% then 0, then 100%, etc. Some people use TThrottle from the same maker as BOINCTasks to keep temps in check by controlling usage.
