hi im new to watercooling but i have been reading on these forums for a couple of years and have built a few pc's myself, well heres an idea im toying with just want some feedback, rite i was wondering if it would be feasable to put a radiator inside a mini fridge whether it be a standard rad or passive? i know there are many ideas of mini fridges floating around but i dont think i have ever seen this idea b4! if i was to try this would condensation be a factor to consider?
 
Then you would have to mess around with R134 freon. Read up on refridgeration as it isnt the same as water cooling. Think about how much sense that question made. How would water make the air around it 40 degrees?
 
Why whould you have to mess with freon? What he is sugesting is simple, a standard water cooling setup with the rad placed in the fridge. Drill 2 holes in the door where there is no other crap just insulation. Run your lines through and your done.
 
Not that much cooling benefit, and you will overstress the compressor on the mini fridge. Mini fridges are not made to handle a constant heat output from a computer, so the compressor would be running all the time which it was not designed to do.

You are better off taking a window AC unit and modifying it to act as a true water chiller.
 
Sorry, I thought he meant he wanted to use the minifridge's cooler and then run it to his PC waterblock or something. Really sorry, I should have paid more attention. It could drop the temps a few degrees. If you have extra money laying around, go for it.
 
I was contemplating doing something similar with a mini fridge, but after reading up about it, like was previously said, the mini fridge's compressor isn't designed to remove that kind of heat constantly. They are designed to remove heat only periodically (the food in your fridge doesn't warm itself up after it is cooled), and would put too much stress on the mini fridge's compressor. Last thing you'd want is for your cooling system to fail.
 
Just get a cheap/old etc. window AC unit, and as was posted previously, modify the coldplate to circulate air through the radiator.
 
Supercricket with Ghetto Lanparty has quite abit of experience with using a window AC unit to cool a computer. Over the last two Quakecons he has had his fishtank computer there using the AC unit to cool antifreeze going thru the cooling blocks on the motherboard submerged in mineral oil.
 
There is no such thing as "R134 freon"

There is freon, and there is R134a, two very different substances.

Well, you could make a blend of CFC gases and R134a.:D It would just be illegal.
 
its pointless to just sit a radiator inside a mini fridge. it may work for a few minutes, but then the temp inside the fridge will just go up (to above room temp)

this has been tested many times.

the easiest way to use a minifridge, with the best results, is to actually bend the fridge's evaporator so it sits in a tub of water/antifreeze. like so:

here's a setup i ran back in 2002

this is the best way to use watercool w/ a mini-fridge without going directly to a phase-change setup.
 
Helped a friend with a mod like is posted above (evap in a container of water). Worked ok for awhile, except, as noted before, refridgerators are not designed to run 100% duty cycle. We ended up having to mount 4x80mm fans to the exterior condensor on the fridge to keep it cool. Really more trouble than it is worth.

I think I mean R-12. Isnt R-134a the fake refridgerent?

Yes, your household refrigerators, windowshakers, and car a/c are all fake. Those epa bastards!

Although modding the minifridge's condenser is a way to allow the compressor to handle the added load. The compressors themselves are more than capable of handling the load. Heat buildup is the problem, as most small minifridges have the condenser built into the exterior wall of the fridge. Actively cooling the entire minifridge is probably more trouble than its worth, as stated before.
