I think I've experienced situations where strong air flow due to fans or whatever cause sound to resonate in ways not heard when fan is off.
Anyhow clearly many things (fans, fuses whatever) CAN affect sound. The important questions are DOES IT in each specific case or how likely in general .
The only thing safe to say probably is that no two cases will be exactly the same, no matter what, so what each person hears in each case is likely different for many different reasons.
Generalizations seldom work out well with hifi sound. Too many variables to take into account many of which may not even be clear or known.
