The Fan on the GPU ought to be on.....at all times... unless the rig is out in the open at the north pole, but , even then the fan ought to be working. The gpu fans are not designed to go completely off, they are designed to spin up with a rise in temps....
Don't do anything first, just get the fan on the gpu replaced or replace the entire gpu.....
Check and see if the cyclic freezing still happens.....although I have my doubts that it will continue... but it's worth the try.
