Lowering water-temp (crazy idea)

Almost next to my PC stands a freezer/refrigerator, if I build water-cooling
would it then be possible to "borrow some cold-ness" from over there ? :D

My very simple plan is to make a 10 liters reservoir connected to the little
reservoir in the PC, (directly or indirectly), and external pump controlled
by a sensor in the little reservoir starting the cold flow when needed

I could imagine that the water temperature hitting the Cooling Block could
be reduced 10-15 deg relatively easy if the project is well done ,....

1. but would the effect in real-world be notice-able ? (Q6600 clocked)

2. how low could I take temp without condense/humidety problems ?

3. Is the hole idea possible or just sick ?

Sorry I had to ask ;)

i'm gonna say that the fridge/freezer is not ment to keep making things cold, it works by making them cold and then keeping them cold with good insulation....

It will work, to a point, how ever u with probly end up burning the condenser out in the fridge....
 
Could work, ive heard whole computers beeing cooled in freezers before without burnout for 24 hours. But fridges can never cope and almost always burn out. Ofcourse the problem with putting water in a freezer is that it may well freeze lol Have to keep the flow rate pretty high to avoid atleast part of it freezing. Condensation would occur at anything much lower than room temperature really.

Try it, if you don't mind risking your freezer, but id get a cheap/free one of free cycle or something first and try that out.
 
hmmm,.. ok :(

It was funny to play with the idea,... but guess I just forgot to eat my pills :rolleyes:
 
grrrr, common myth and completely incorrect. compressors don't burn out if used for a long time, what kills them is constantly turning on and off. but if they are on all the time temp in fridge is , well, way way to low for stuff you keep in the fridge.

because of the temp controll circuitry added to the phase change setup inside a fridge freezer it will turn off if it hits 1-2c, then turn back on maybe 5c. the problem with a pc is instead of turning on for 5 mins, then being off for an hour or two like normal operation , it will turn on, heat up within seconds/minutes, and turn on again. which also gives it no time to return to normal starting conditions, the oil can get in the wrong side, the gas can go where its not supposed to etc, etc.

plenty of people have made 24/7 working water chillers, and even a few people used to turn them into proper direct cpu phase change systems by removing a unit from a freezer and removing temp control circuitry.

phase change systems are well, they only work when they are at a certain level of bulletproofness. if they can work for 5 mins, then can work fine for 365 days 24/7 a year, they just can't turn on and off every 3 minutes. which is similar to most stuff tbh.


So the unit is fine, rip one out of a old freezer and make a chiller, but you'd have to deal with condensation, rip one out, get a massive condensor and radiator, have air con repair guy, do parts of it yourself, get a friend who knows how to bend the pipes, replace the condensor, duct it apart and have a little air conditioning system to cool the computer/room., but don't stick a heat source inside a completely normal fridge/freezer.
 
There are actually a couple of members kicking about who know what they're talking about, so if you really do want to do a ghetto mod I'd suggest having a chat to them first (Fatty1 makes this stuff, both phase and chillers in his spare time, so TBH I wouldn't listen to anyone else!)

It is much quicker/easier to simply buy the appropriate piece of kit ready built, and probably cheaper too. I know Fatty has a couple of chiller units for sale in the MM, but you need a fair few more posts before you can access it - might be worth asking him direct though, he always seems to have kit floating around :)

In a nutshell though, from my limited understanding (an I have run both direct phase and chillers for a couple of years, though don't profess to know much about the internal workings beyond the basics!), the problem is overload. The phase unit (be it direct die or chiller) needs to be able to dissipate the heat generated by the kit. (Hugely simplified) If the unit isn't designed for the load then it becomes overloaded and breaks. A fridge compressor unit isn't designed for the loads produced by your machine - hence it breaks! Usually the older chillers were ripped out of pub beer chillers, but now days they are far better and produced for purpose. Considering that you can pick up an excellent rig for under £100 I'd go for that - then come back and we'll help you with the basics of installing/running etc...
 
could u just leave it the rad infront of an small air con machine then ?
or even better, by a small fridge cut holes so i can blow the chilled air out the front or side on to the rad ?!?

or am i just over thinking this one for him ?!?
 
Fridge would still have to be cooling the air pretty fast to cool air significantly enough to be worth the electricity, which would again probably burn it out.
 
From the sticky:

1) What if I put a reservoir in a mini-fridge?

A) A mini-fridge (even a big fridge or freezer) is designed to take a room temperature item and cool it. Once cooled, it remains cool thanks to the fridge's insulation and minimal cooling. If the reservoir is in the fridge it will be being fed warm water constantly requiring the fridge to run continuously. It is not designed for this and will quickly fail. Even a freezer will have to work harder than it is designed for making it far noisier than simply using a fan on a radiator.

A lot more info there too.

Thanks for the answers, and some interesting links, the phase thing is new
to me, and would likely help my old D 805 chip more than it would a Q6600 ;)
(in one of the links it was taken to 6 Ghz), anyway what I had in mind was
a very simple thing, nothing fancy, I see now that it is not realistic,...
