Graphics Card Fan Not Slowing down after Keyshot is closed

[rossco]

Hi

I've noticed that when I run Keyshot the fan on my NVIDIA QUADRO FX4500 goes at full pelt (sounds like a jumbo jet about to take off).  I assume this is correct but when I close Keyshot down the fan never returns to it's normal steady drone even after a few hours.

Any ideas?

Shouldn't have anything to do with KeyShot. KeyShot is CPU based only. And the GPU effects we have in there will tax the graphics card very little, and only if you enable them.
