Also if you add a neutral wire you could probably run a 120V fan.
I'm giving this compressor to someone. I realize people are saying that I'm over-complicating it with a fan. The part I'd like to keep simple is not having to change out the factory plug and cord. It came with a 6-20P and I know he's got two 6-20 receptacles in his garage.
While in some respects adding a neutral wire makes a lot of things more logical and straightforward, it would also require him to put in a 125/250V receptacle/circuit. (which I know he probably won't want to do)
Find a real fan , how much cooling you think an amp of 12v is going to do? This is already way complicated. All a substitute for a decent comp in the first place.
This isn't directed at you sberry, regarding the 12v fan comments, this is the fan I'm referring to:

A 12v 150mm 300cfm fan is very different than a 12v 30a 2500cfm fan. I have a pile of those computer CPU fans so was thinking of something small and quiet out of the pile I already have.
I've got welding wire, paint and copper I had on hand into this so it's still basically free.
sberry, yes I know it's a substitute for something decent. It'll be his first compressor and it'll be a LOT better than the craftsman oil-less I had as my first.
240V muffin fans are available, cut out all unnecessary **** & run them on line voltage, remember KISS.
It'll be fine to tap it into a 20A 240V circuit? If yes that'll be very simple/quick/easy.
What amazes me even more is the quality endorsement for some of these ideas. Most of them are not dangerous but lots of them don't have much value or they have a chain reaction that new guys to this type of thing read of them, think they got to have em not realizing they are a waste of time if it's not a total hobby which is a different issue.
I get it. This is a hobby for me. If I was a contractor this would be a perfect jobsite compressor for daily abuse. Also if I were a contractor I'd be a "time is money" guy and would never put this much time into a hobby, I'd buy some junk from the big-box and replace it in a year. I don't value my free time like someone in a trade does. If you want to hire me for work that's different but this is fun/relaxing for me.
I'm going over the top with this compressor because it's going to be a gift and he doesn't have the room for anything bigger. Also it'll be his first compressor so he won't know any better. I shoved over 50 feet of 1/2" copper into an aftercooler so that plus the dryers should get fairly dry air down to his loading stations and the pneumatic loader I'm also building for him. It'll be the gift that keeps giving. We own a bunch of same/similar firearms. I don't have the room he does for loading stations, etc but this way all I have to do is collect my brass.
We'll see. A 300cfm fan will be plenty fine to cool an aftercooler and supplimental compressor cooling.
