Restoring a Star Trek SOS and the rear door fan is so loud. Sounds like an airplane taking off. I have also used in the past some new ones for a San Fran Rush The Rock etc, and they were by no means quiet either. Does a less noisy brand exist or is that par for the course with these 110v ?
 
I looked into this too for my Turbo and just decided to leave it out like a lot of other owners do. Only way I can think of is to get a Notcua fan and decide how to run it with the lower voltage requirement.
 
The noise (dB) will vary with factors such as the speed of the fan (rpm), size of the fan (mm), and rated air flow (CFM). The power draw will also vary.

I don't know what size was used in Star Trek, but 120mm tends to be commonly used.

116 choices in stock at Digikey at the moment:

Note that CFM can vary anywhere from 21 to 164, and dB from 20 to 60.

My favorite 120mm cabinet cooling fan that provides a balance between air flow and noise is this one:

In applications where I need less air flow and a smaller fan, I'll use something like this 92mm unit:

Wow, very helpful post. Thanks for the contribution!

Thanks for the suggestions. Buying a couple of new fans for SW and Afterburner has been on my to do list, and I dread picking something out, will go with one of your picks.
 
Does it have to be 110V?

You may have more silent options using 5 or 12VDC computer case fans, I did this on a Track & Field cocktail that sounded like a Harrier jet taking off that's completely silent now.
 
Depends upon the situation and what convenient power sources you have to tap into inside a cabinet. For a fan that is blowing cool air into a cabinet or exhausting warm air from a cabinet, I prefer AC.

In classic Atari games where I want an internal cooling fan blowing over some component, I'll use a quiet 80mm 12VDC fan. I'll connect it to the unregulated DC voltage (which usually runs around 11 VDC) on the A/R board.

A larger diameter, lower RPM fan will be quieter than a small diameter higher RPM fan.

I wouldn't recommend connecting a 5VDC fan to the 5 volt supply in a cabinet - just because that's running all your game logic. Don't usually want to add any unnecessary load to it.
