Ok, this may be the dumbest question that's been asked in a long time... but it's been bugging me for a while and no one can answer me so far.

------

Can I put a PC in a small refrigerator and run it safely ?
Will it form condensation and fry itself ?
Can I have the PC in a sealed unit inside the fridge ?

-------

I live in a VERY hot country and have to run the Air Con all the time to get a safe working temperature. I bought a decent Lian Li case with loads of fans and the CPU runs at 38-40 degrees Celcius under load. (Athlon XP 2600+)

Running the AC all the time makes for large power bills. So I had the idea about buying a small fridge and putting my puter inside...

Is this idea feasible .. or a load of bollocks ?

Looking forward to some replies !

do you mean your load temp is 40C when air-con is ON?

what about if air-con is OFF?

40C is perfectly OK for a load temp...

Yes, 40C when Air-con is on...

The trouble is having to have it on all the time to keep the room and PC cool. Which is leading to high power bills.

Also I'd like to do a little overclocking at some stage

Most mini fridges are not made to run 24/7 (Or even more then a few minutes)

They are made to removed any added heat to the system, and then insulate it like a cooler.

If you are running a PC then you are adding heat constantly, and the fridge has to run contantly.

There is of course the possiblitiy of condensation shorting out components.

But can it be done: Yes
Has it been done: Yes

Check around the net, it's actualy been done quite a few times before with mixed results.

it would be cheaper going to water cooling system.

I dont think a water cooled system would really help. A water-cooled system in most cases is a rather passive method similar to fans. The concept is the same. Move the heat to where it can be absorbed by cooler air. However if the heat around his computer is hot (as he says it is) this would not help. In response to the refridgerator concept, it would probably cause condensation. In most cases when hot and cold combine it forms condensation (ex. the outside of a cold glass on a hot day.) What might interest you is this item: http://www.frozencpu.com/cgi-b...ncpu...pu/cas-193.html' ">http://www.frozencpu.com/cgi-bin/frozencpu/cas-193.html. This would be useful in an extreme circumstance such as yours, and would most likely even allow you for overclocking as you said you might like to perform. However if this is too expensive for you, an alternative would be a peltier module.

does the processor run stabl without the air con on? if so switch the air con off... you dont need it (unless you ned it yourself... maybe i should have said the computer doesnt need it)

Do you wish me a good morning, or mean that it is a good morning whether I want it or not; or that you feel good this morning; or that it is a morning to be good on?

A dumb answer:

You could keep the heat sink misted with distilled water. If the cpu creates 100W of heat; Heat of Vap. for water at 50degC is about 2.4kJ/g; You would need to evaporate about a cup of water in an hour and a half. Sounds reasonable.

Next you would need to find the surface area for that rate, given temp, pressure, and humidity.

Or maybe just dunk the whole thing in a vat of oil. Like linseed oil.
