Eh, if its taken from inside the fridge, perhaps not. But, if you're blowing air from inside the fridge, the air in there would have to be replaced. Where would the new air come from? Would you create an intake hole as well? I think the supply of cold air inside would run out after a short time of cycling. The new air would also need to be dried, as you suggest.

I've seen people use local (portable) AC units for similar activities. Condensation can be an issue, particularly over an extended period of time.

One solution (if you're serious) might be to run a water cooling system and place the radiator in the fridge. This would cool the coolant, not the ambient air. Plus, it would give you a closed loop system.

Just a thought.

Not a bad idea, although consider this.

If the returning coolant is anywhere near the temperature of the fridge (and if the air within the case isn't run through a dryer of some type) the return tubes will still develope condensation. :?

It's hard to run such a cool running setup without condensation.

Might consider building upside down so any condensation drips away from the board, make a leak container below. Hmm, got mushrooms at dinner last night again :lol:

provided that the air and temperature inside the case are consistent, the only condensation issues will be on the outside of the casing itself.

I did a quick experiment involving condensation... which btw you can see here: http://www.motherboards.org/forums/view ... sc&start=0

The only solution I came up (with regards to my experiment... I think...) is to install a temp sensor that will measure the water temp and in turn the sensor will turn on and off the peltier when temp settings hit their marks... :?

Rather than use a refridgerator and have to worry about "drying" the air, why not utilize a device in your house that already does this...

Your A/C!!

You can use some PVC piping and reroute the air into your computer's intake fans. Unless you're doing some SERIOUS overclocking, you wont notice any change in the temperature of your room (maybe a degree or two at most).

If you're on a budget, you could do what I did a few years ago and make your own...

If you don't want the unsightliness of PVC or lots of duct tape nearby, consider creating a reverse heatsink. Stick a large amount of copper tubes/pipes into the fridge, and run them BEHIND your computer's intake fans. Cold air from your fridge will travel through the metal, where your fans will then blow the chilled air around the metal through your computer case.




Perhaps I should've asked this first:
Are you looking for a budget smart solution, a no-holds-barred solution, or something in between?

Why not get a small apartment sized refrigerator and put the entire pc case inside, then run the cables out the back and put the monitor and keyboard on top of the refrigerator. Doing it this way will put all of the condensation out side of the refrigerator where it will be dried by the condenser fan.

You may also have some room for a brewski or two.......

the computer would create to much heat and it wouldn't work ...
