yeah, somewhere on the fan it will tell u what are the power requirements

u r better off using a power supply, for running 1 single fan u can find PSUs as cheap as 20 bucks or maybe even cheaper online. or just salvage one from an old computer case.

or u can find the power requirements and use a matching 3rd party adapter u may have laying around the house to hook it up directly to the wall outlet.

just dont connect it to the plug without proper power managment! that will ruin your freebie and make a bad smell!
flyingimam Reviewed by flyingimam on . Computer fan question I got this cpu fan free from work. Its from a large electrical circuit panel. Its got a metal casing and fan blade and its heavier than any other cpu fan I've seen so it seems to be "heavy duty" I guess you could say. It says 230v and 50/60Hz. My question is how much power does it need to operate at max cfm? 12v? Thanks for any info!!:jointsmile: Rating: 5
