Depends on the old fan. If it's noisy because it's filthy, or because the mech is worn out, it could be making quite a bit more noise than a new larger fan would make.

It's all depending. Maker, type of bearing, fan blades.....there's no general rules really, but I meant that generaly a 120VAC powered fan that is new and has the same size as a comparable 12VDC fan is noisier because it's more powerful.

Can't argue that... but his fan is 25 years old and ran in a filthy environment for a lot of that time. I agree with you that he should just swap it. Any replaceable part like that, if you have any question, just swap it. No sense in doing all this work and cheaping on a $15 part.

As I said, they are not cheap and certainly not 15 bucks.
Since my cockpit is in "service" right now anyway I just removed the fan to have a look.
This is the fan in my machine, I know for sure that it's original because it's dated 6-3-1983:
Rotron Whisper Model nr. WR2M1
50/60Hz 115VAC 6,8W
Strangely no CFM indication.
But the amazing thing is that it's still in production. The company is now Comair Rotron and here it is:

Amazingly it's a sleeve bearing fan. Ball bearing fans are known to be more silent and reliable so it might be better to find a ball bearing equivalent.

Uhhhhh, that is, not sure it's still in production, just found this:

Weird that their site is still fully functional then......maybe they did a re-start ?
[Edit] Mmmmmm, looks like they were bought by a Chinese company as their headquarters are now in China:

Which makes me want to look for a Papst equivalent really.......Best known brand.
