300mm electric car radiator fan testing for use in a PC

Testing a 12" (300mm) 800CFM car radiator fan to see if it can be made quiet enough to work inside a PC.

cool ive had a high out 12" on my computer runing off a 13A 12v power supply.when i was testing it i got my finger cought in the blades and about got it cut off.VERY sharp blades but a rediculus amount of air flow 3TB hard drive 3.7ghz processor 8gb of ram 2X 4gb sticks.dont use it any more, upgraded to a lap top

What power supply do I need to run this?

I have a graphics card and a few fans running. but I can take most of the fans out if I'm gonna use this...

My power supply is 730V

@TmRCng I know what you're going through.. :P

the car fan pulls a bit over 100A when starting it and it pulls about 35-40A on its full speed.makes you think about the electricity bill and it makes ridiculously loud noise and when its on full speed and if you dont have it attached to your pc case well,it can easily pull itself off from the case or blow all the stuff in the pc apart or away or so.

I wanna fit this into my laptop ;D

@TheCrazyFinn Condensation occurs when a component is at any lower temperature than the ambient air, and the air an AC expells is well below that. And I've never seen a conventional case that is airtight, so allows ambient air to penetrate it.

Anyway, I think an AC is too loud for viable use as everyday computer cooling. The sound gets quite annoying after a moment, and I have to turn mine off when watching videos because I can't hear anything.

@armorfid Condensation only occurs when warmer air comes to contact with cooler components. AC can't cool the components to a lower temperature than the air it expels. If all the air passing through the system comes from the AC, there will be no condensation inside the PC. Outside may be a different story... ;)

[armorfid]

@TheCrazyFinn Not on the warm components, but anything that the AC is able to cool down enough will condense water, such as the casing.

[TheCrazyFinn]

@armorfid Anyways, moisture from cool air doesn't condense on warm surfaces. So moisture from the cool air coming from the AC system wouldn't condence on the warm PC components.

@TheCrazyFinn cool air exhaust, forgot to specify.
