Mac AMD HD 7950 Fan

(moderation:
After I got my 2012 Mac Pro outfitted with a AMD HD 7950 so I could run Mojave I noticed that Einstein@Home was driving the GPU hard enough to run the 7950's cooling fan constantly. I was able to find a Mac temperature monitor that could tell me the temp of the 7950. It was running around 160 F which was considered by many on the net as acceptable. Recently I noticed the fan had stopped running. I could no longer find a temperature monitor that supported the 7950 so I was left with the question of whether Einstein@Home had somehow reduced its load on the GPU or maybe the fan had failed. No knowing how to determine which it was I have stopped running Einstein@Home. It was the only BOINC application I was using. I regret shutting it down and had no choice as the possible destruction of 7950 would have been catastrophic for me. Does anyone have any information on the situation? Thanks.

I've got no experience with Macs but I assume this is a desktop computer and not a laptop as you've upgraded the graphics card.
An easy way to determine if the fan is working would be to remove the side cover and visually look at the fan whilst running. It might also be a good time to chase away any dust bunnies lingering about (turn off and unplug first!), compressed air would be preferable but a vacuum would also do the trick. Just be careful not to spin fans to fast or shorting something out.
If you've gone from running Gamma-ray work to Gravity wave work on the GPU then the load will be less and thus the heat output, so the fan should probably not have to work as hard.
