Turning Off Ampex MM1100 Fan

I'm in a pretty small room with my tape machine pretty close to my mix area. I moved the machine out of the room, but didn't like having it out of site. Would it be possible to temporarily turn off the top three fans that cool's the upper portion of the machine while recording? I'd put a switch on the machine to do this. Most of the time, the machine sits idle/on and I mix through it's electronics and back to my mixer.

Thanks,

Rather than turn all of them off, consider replacing them with quite fans.

Messing with the cooling system on ANYTHING is usually a bad idea.

Look at websites that build PCs from scratch, usually they have fans that are super quiet.

Right, I completely understand that the cooling is important to keeping things from overheating. Just trying to quiet the machine down a little.

I'm going to check out Fry's this weekend to see what they have. The fans on my machine are rated at 115vac with a noise rating of 33dba and 56 c.f.m. output. I couldn't find any like that on their website, but maybe they have them in the store.

Thanks again,
Nate

Get quieter, more efficient fans and try reducing the voltage going to the fans so it spins at a lower rpm. MCI JH24's used to do this. IIRC, they ran their fans at about 90-95v
