Would it be possible to take apart a dorm fridge and hook up the parts to the intake of a computer to cool it?

Yes, technically, but they don't have sufficent cooling capacity. What you can do is run a metal waterpipe through the refrigerator's coolant loops with a slow flowrate pump. Then just cool the CPU or something. Or you could just go water cooling, drill a hole in the fridge, stuff a radiator in the fridge, seal the hole with clay...

I believe the fridge with the radiator inside would have sufficent cooling capacity to cool an AthlonXP 1700+ or an AthlonXP 1800+, keep it at around 40C.

I wouldn't suggest trying to cool everything with a refrigerator, you'll overload it. Open up your powersupply, (Be careful, and after you disconnect the power press the power switch to make sure the capicators are drained) take out old fan, put in vantec silencer, cool the AthlonXP with passive cooling from the radiator in fridge (You can stuff the resivour and pump in the fridge too and just use a water block outside the fridge)

A word of advice, if you go with radiator in fridge approach, put it in the bottom of the fridge, as heat rises.

you would be better off with a fish tank pump and drill two holes through a large heatsink and recirc the water with that.... i think the condensation from the fridge would mess stuff up because it gets too cold... just my thoughts.

What? Are you insane? Any dorm fridge that still works should be filled with beer!

Anybody try cooling with beer? :)

And, why not just put the whole computer in the fridge as is with the panels removed?

Had this whole discussion over on OCWorkbench just a little while ago.

Upshot is, if you open the fridge to get out the cold beer in it, then you get warm air in there which condenses on the board and has unfortunate consequences.

So you can either use a water-cooled system and run the water through the fridge to your external pc, thus preserving your beer-cooling ability, or you can seal the fridge with the board in it, thus relegating yourself to luke-warm beer in a styrofoam icechest with little pieces of ice and beer labels floating around in it.

Choice is easy, No?

Berr HAS to go in the FRIDGE!

Condensation is a main concern. What you could do is setup a water cool system and uses your toilet water tank for coolant.

The mini-frig cooling has been tried and debated ad nausium hard forums and Overclockers.com.

Setup 1: You simply run air intake thru the mini-frig.
Result: nothing.. the frig cant keep up (as previously stated)

Setup2: You set up a water cooling system, and run your tubes thru the frig
result: nothing, water is moving too fast to get sufficiently cooled (also prev. stated)

setup3: You set up a water cooling rig and put your radiator inside the frig
result: 2-3 degrees cooler.

setup 4: you put 15+ feet of winding copper tube in the frig and run it thru your water cooling rig. The idea being more tubing means the water is circulated thru the frig for a longer period of time.
result: 3-4 degrees cooler. Sometimes nothing, it depends on how high the frig is rated and the thickness of your copper and the water temp going in

setup5: You air cool your radiator and then pass the water thru the frig which either has winding tubes or another radiator (in the freezer section)..
result: a few degrees cooler

POINT!!! You need a large deep freeze cooler in order to do what your thinking. Even then, you will need to set up a water cooling rig, not an air cooled one. Some folks have had modest success by running a tube straight from an air conditioning vent into their PC. Usually lowers temps by 8+ degrees. If you live up north, you can vent outside (filtered) air into the PC. One guy got below 32F doing that.
For all the scenarios that drop below ambient temp, you will need to insulate the socket to prevent condensation..( I know, it depends on the dewpoint.. but lets not go there)

In short: Nope, it wont work
