Krell KSA 50 (fan?) noise?

Also, fans are super cheap, and thanks to the PC industry, a lot of them are a lot quieter.

While you may be able to service it, you may also wish to just buy new. Make sure you match voltage and cubic feet per minute (CFM), then try to find the quietest one you can.

Best,

Replace the fan it's over 30 years old, but don’t get sucked into buying expensive roller bearing type they are noisy, use good quality bronze sleeve bush type, these are the quietest.
