Cooling Fans Question

[Crumm]

What kind of voltage do computer cooling fans run on? I have read about installing low draw fans in my camper to prevent water line freezing but I am not so sure they come in 12V. Do they?

A computer power supply usually only provides 5v and 12v (there are exceptions)

You should be able to get 12v fans pretty easily from a computer supply place, or radioshack

I use a 12v one to create a draft in my trailer refridgerator vent.

most chassis fans are 12V.

i bought about 8 from radio shack last year to use for the movement of air in the rv to help with cooling things and air flow to prevent condensation
work great.
cost about 10 a piece

How much do they draw?

crumm-

don;t neglect the case fans, they are 120V too.

12V-depends on the vintage and quality. iirc they are somewhere about 8-10 watts each. so at 12V, that is about .75-1A. that wattage i remember from having to do heat loads calcs once, so its propably pretty conservative and actual draw is way less.
