From the description of the noise that the fan on your KPA-100 is making, I'd guess you have a defective fan. I never hear the fan on my KPA-100. I have a pretty quiet shack, and operate with the volume fairly low on the K2 and I have only noticed the fan running a few times.

Whizzer - what a good name. It actually startled me when it came on and the noise interfered a bit with copy of the weak station I was working. I may have to go to closed headphones. The MEs here at work tell me similar things. Some of the pads are better than grease. Good, grease is a PITN (neck) to work with. I'm also glad to hear the pad reflows when it gets hot the first time. That answers a concern I had that maybe things just aren't tight enough yet. I have a few muffin fans left over from a PC build-up. I think I'll set something up. The 60 deg air in my basement plus some fan-action should keep the whizzer under control ...
