Thanks, very much agree.

I took a naive approach to it before having any clue about electronics, just replacing one of the (3) internal fans with a quieter one of the same voltage. Mostly to see if that would work.

While it functioned, the "fan warning" light was then permanently on (with the replacement fan in).

If I still had the gear and were to do it again, I'd investigate properly and figure out a real solution. :)
