And adding a fan onto the cab itself won't help, as the inside is so large that airflow will disperse and won't be strong enough. The only reason arcades had bare mobos mounted on the cab was that they weren't very processor intensive, and the chips never got very hot.

Well... I obtained a Hang-On cab that has a fan mounted at the very top most position around the back. I got this cab sans monitor, but there is clear evidence it got too hot inside since the smoked acrylic is warped right where the monitor should be. (I haven't tested the fan yet. Too low on priority list.)

IRT to OP

I don't know how your cab is designed, but other solutions to try (along with regulating the fan speed).

Use a larger fan, look for one with baffles or a silencing design. A small fan spinning at a high RPM is going to sound a lot louder than a much bigger fan spinning at a low RPM while pushing the same, or greater, amount of air.

Visualize slicing the cab in half and look at how air might flow through the cab. Is there a shelf that might trap hot air?

One idea I've never really had the chance to try. If the sound comes from the fan vibrating too much (at that point I replace it, but meh) try deadening the sound using rubber stand-offs to absorb the vibrations. Commonly used with noisy HDD's. Another is to line the inside of the cab with sound baffling, like the foam "egg cartons" used in studios. I don't know how this will affect heat trappings, which is why I never really applied it to anything noisy (not a cab yet). I also don't know about any static electricity that might be generated by the foam.

deadkenndys1105:

Before buying a fan controller try taking off the fan if your PC doesn't really need and is in a cool spot.  If you need the fans just get those rubber spacers they make for them.  They will sometimes cut down a lot of noise.  I need to take my fans out of my mame cabinet because they are a bit loud and there really not needed because I have it really opened up.

RayB:

Has anyone tried lining the cab sides (interior) with 1" foam? (spongey kind).  Or even egg crate style foam.  In theory it should really dampen noise.


Joystick Jerk:

True, but that would really only dampen the sound actually coming from within the cab. If it's a fan mounted on the side of the cab, it would be just as noisy with or without internal sound dampening.

Echo that.

Really.  There's an echo in here.

The guys on the forums over there know more about quieting a computer than anybody, anywhere.  If you really want to silence the thing, that's who to talk to.
