phase change and chiller experiment

[joshuaeddy27]

just wondering if neone happened to know what the effect ot converting the mach 2 gts or whatever phase changer is on the market now and adding a fish tank or something around the condensor and all the other cold stuff, filling with a mix of water and antifreeze and a submerged pump, then piping the chilled water to other components

would the evaporator be taxed and not put out the numers by a serious amount, such as an amount less than chilling the entire thing anyway.

just curious what others though t about this.

id love to do a straight phase change with the cpu, but i have a gpu and chipset to worry about

OR

does neone know almost the doing the same thing with industrial refridgerant and equipment only in a large fish tank, filling fish tank with mineral oil or some other low temp dielectric and running copper lines through to chill the water and then pip to gpu and chipset

plz give me thoughts ideas, gripes, complaints, or nething else you might have
and plz remember your speaking to a newb, i have little to no knowledge or any of this except what i have read. all i have ever done is low grade water cooling

ok, hit me upside the head, i realize after saying what i just said that the chiller idea would nto work in the premade phase change coolers, but plz give me some other ideas for a complete solution

welcome to the board

hummm well i can think of a few ideas to chill the gpu, chipset and cpu from one evaporator but you'd have to be quite handy with machine tools to make any of them...

regarding the mineral oil idea, yes you can do that, see the goo cooling article on the front page, but you need an effective way of cooling the oil, and any serious amount of cooling will make the oil stiffen up so much you can't move it (i managed to drop my tank of oil to -27c when it started to get quite thick.

however... what exactly are you trying to achieve? with phase change on the cpu you've immeadiatly removed the main heatsource in the computer meaning the gpu and chipset operate at a lower ambient temperature and no longer need such extreme cooling, you could probably get away with a serious air cooled solution! or at the very worst a secondary water loop, i've not seen any really radical improvements with super chilled graphics cards as yet (but then again not many people do it so maybe we are missing out) again chilling the chipset has never seemed to release any really impressive overclocks, water is the most i would put on it.

check the gallery for dfrancis's lian li, its got phase change and a seperate water loop, it looks crowded but it got nice and cool and some pretty good overclocks :)

i have thought of another easier way to do it that doesnt require quite so much ffort
on the other hand it does rewuire me getting my hands on two window ac units that are about 12000btu and 8000btu. the cpu is evaporated directly onto the cpu like any "old" phas change is. the 8000btu evap is going to be stuck inside of a copper pot that i weld a top onto and then this become my resivior for a water cooling system that is more antifreeze than water. this pot is then suspended inside of another fishtank for the mobo tank resivour to cool it down at the price of a couple degrees to the chilled water.

i dont forsee any problems with this idea except that i am going to have to use one of the industrial shelves i have as a pc case, but i kinda like he idea anyway.

im just on a mission now to find the highestbtu , most effecient window ac or find a cryo fridge that is broken and my dumbass knows how to fix it or where to get spare parts. on the other hand, i want to use very power effecient solution because i want to run this system 24 hrs. I want to do a le manz of overclocking.

any other ideas you may have i would appreciate. and thank you for you insight.

You can cool the GPU and the CPU from the same chiller if you do it right. Run twin pumps in the same reservour where the chiller is. You'll have to use an AC unit that pushes at least 5000bTU.

I used a 5080bTU (115v AC) unit on mine. Worked pretty good. One of the main problems was keeping things dry. Condensation forms between the GPU and the waterblock if you dont seal it off really good.

It would get cold enough that if I had the waterblock off the GPU wtih the base exposed, it would form a thin layer of ice on it after it sat running for a bit.
