To help with the noise try replacing the fans with high quality ones. I threw some nocturnas into an old managed dell switch and it quieted down immensely.

Just be aware that sometimes they change the pins around from the standard pinout, I blew out one of the fans before discovering this. Fan still works, just lost the rpm monitoring :(

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. :)

Server fans are not cheap, they’re smaller and faster. Look at current and CFM rating. They might look insane from DIY market figures.
