fans-computer in house

[BuschPilot]

I am thinking of adding a couple fans in my house and am wondering what kind i need. i was looking at some computer fans but they are ac. will that work? thanks again.

I'd get a few from fish house supply. We put 4 of them in our wheel house and it made a world of difference, quiet and very low power consumption.

I have access to a few computer fans, however do you need to run them off of some sort of converter/inverter, or will they work off a regular 12V battery. I am thinking of putting a couple in my perm, but am unsure of the proper way to wire them. I currently run my lights and other fan off my marine battery.

aczr2k - How did you mount the computer fans in your house? I bought one for my wheelhouse. They seem to need a quite a bit of clearance behind the fan for them to push (pull) air down to the floor. I started by mounting it flush to the ceiling - that didn't work at all. Now I am trying to find a productive way to mount with clearance behind the fan. Thanks for the help.

Yes computer fans come from a 120 volt system, but if you look on the fans, most are either 12v or 24v. 1 of the fans I use in mine is 24v and does run on 12v. All 3 of the fans I have use very little juice, and move just enough air to make it very comfy. Each are about .25 Amps per hour. Combined about .75 amps. on a 150 or 200 amp battery,................well you do the math on how long they will run.

All computer fans are DC 12V. They will run faster at a higher DC voltage and slower at a lower DC voltage. The whole point of a PC power supply is to turn your 120V AC into DC +12V, +5V, +3.3V, -5V, and provide a DC ground.

For the not so electrical savy guy, does all this "+,+,+,-,AC/DC" mean a converter is reccomended?

The only AC/DC I really understand is the Band.

Nothing needed. Hook 1 wire to the positive post of the batter and the other to the negative and it will spin. Reverse the leads and it will spin the other way.

Thanks spearchucker,

That is all I needed to know!

For the not electrically savvy the red wire goes to the positive terminal and the black wire goes to the negative.

What I was saying for the computer is that the power has already been converter to essentially battery power where you plug computer fans in (of course most new systems now have more elaborate fan speed control systems to minimize noise, but we won't go there).

I used really long screws when I mounted my fans and put small tubing around the screw between the fan and ceiling as a spacer.
