OC Newbie is correct. Condensation is not an issue here, unless the fridge is not sealed properly. If the door seals are damaged etc. or if for example the route taken by the power and other cables is allowing external room-air into the fridge then yes there will be a massive problem with condensation. Expanding foam and or silicone may help here.
Also, do not open the door (unless absolutely necessary) once the system is going as this also will allow air in which will hit due-point once it is cooled... unless you're using a frost-free system. Air in a properly sealed fridge or freezer is very dry.
Regarding the compressor being overloaded... it might be an idea to use a) a larger fridge or b) a freezer instead of a fridge but with its thermostat set to say just above freezing.

due-point
Looks like someone is "dew" for a trip back to english class.

The original concept of the 'PC-Fridge' was to provide a quiet, efficient and REASONABLE cooling solution for a PC.

Yea I could chuck a PC into a deep freezer or outside if I lived in near the arctic circle but is that reasonable and/or efficient for the average user? No.

Point is, the original concept does not work. It's been said millions of times. A refrigerator compressor cannot run 24/7 to cool a constant heat source and therefore cannot keep a PC cool for any reasonable amount of time.

refridgerating a pc works fine. great in fact. all you have to do is refridgerate it in an air sealed compartment pressurized with an inert gas. My personal preference is helium. It is non conductive, cheep, readily available, not to mention the fact that helium molecules are less than a quarter the size of a nitrogen molecule which allows for quicker heat dissapation. it is only necessary to pressurize to maby a quarter pound or so just enough to eliminate native moisture in the air. and there ya go problem solved...

as we speak about condensation I would like to add in 2 cents.

A fridge is designed to cool food and keep it cool. The fridge only comes on when it needs to cool the inside back down to a certain temp. And airconditioner dies the opposite.

Thus the refridgerator will die or the computer first.

Inert gases has nothing to do with cooling or condensation.

Pressurization has nothing to do with cooling here.

Virtually all gases are non-conductive (for our needs). Air is cheap and easier to work with than helium.

Molecular size alone does not determine thermal condutivity.
Helium: 0.1513 W/m·K
Nitrogen: 0.02583 W/m·K


You still have not addressed the actual method of cooling.
Once again...

Allow me to correct some thinking here...
This is wrong .

You're right in suggesting that condensation would occur if the PC components were lower in temperature than the fridge's ambient temp, BUT, condensation will ALSO occur if the AMBIENT TEMPS are lower than that of the hardware! - which is so obviously a possibility, if not a DEFINATE.

Hardware components produce heat! - and the air of the fridge will be cooler.


It has been said here MANY times - but this theory is bound to fail if certain things arent seen to.
But to summize - IF the fridge isnt an industrial one (as my friend below said), then the compressor WILL NOT COPE.

I would however like to think - that designing ways of routing the fridge's internal components to cool specific PC hardware components may be a better option.
But I doubt that would see the compressor gaining any lifetime extension under those conditions.

at btw - at least leave the PSU out of the cooling box

what are you guys talking about! this works just fine! for about 15 sec! seesh. now give me a sec to look in my picture folder for the epic fail pic. hmmm. cant find it. the shipment of fail must due.
the reason this does not work is because the system is not tuned to handle a 300w+ heat load that a chill box would need, that and the compressor is to weak and the condensor used would be a bit to weak. anyway. if you would want to use this concept, get a medium powered window airconditioner(7500-10000btu would be perfect) and have it blow into a condenation proffed box. you could see temps as low as -10c.

I have been waiting to get to use this pic!

This topic has been tried and failed over and over on here. Its a bummer but you would be better off using an AC unit then a fridge.

I would like to shift the direction of this conversation. Do you think that It would be possible to retrofit the cooling system from the small refrigerator as a peltier like cooling system.
