Hi, John! I dug up this old comment on fan noise on the ten ten reflector:

Don?t know if that helps, but it may help?..

Totally not in the spirit of the original poster's questions.. but I have to
say I do miss Mike Hyder. He and I grew up together in ham radio, and his wit
and personality were suburb.. He was smart as a whip, and did not shy away from
any problems. And funny... geeeeze... He loved CW, and knew that he was always
pushing my limits when he blazed away at 30 wpm back in our youth.. so instead
of telling me he got a new car, he had to tell me he got an Anthracite Grey
Volkswagen ... He was a huge fan of TenTec, and gone way way way to early. RIP
Mike, you and your volkswagen..
