Also yes he does
My hardware is certainly not designed from the ground up to be used in servers. Most of it is overclocked, and there are 2 video cards connected (Radeon R9 270's), one with a powered riser, which mine scrypto-coins nonstop. It's in an open computer case cut with a hacksaw, and the whole build is designed more for mining than hosting.
But none of it has actually failed except for the fan one time.
However, the whole CPU fan failure is just as likely to happen in a tower server (if it's not in a datacenter).
