Idea/project chilled water cooling FITS

[Skitzo]

well at that rate we just need to figure out the fluids...

ethanol seems to be the best choice.

 

[Skitzo]

just based on the tables i'd go with Propylene Glycol / Water Mixtures because it'll boil not flash. Eventually the dice will be gone so what ya gonna do when the temp rises. you would need a constant supply of dice. we are talking major oc and heat right? it would depend on the thermal properties though

EDIT: Ok i just realized you're prolly not looking for full time cooling with this, I get carried away sometimes.

EDIT: we need to get BLKhogan here, he works with heating and cooling.

her's some more info... http://www.dow.com/heattrans/fsa/silicone.htm#Anchor-Inhibited-47857

attention plz!

im gonna be posting a ton here in the next hour.

 

[Fitseries3]

ok...

here's what i have for the build. i'll be taking the fan off of the rad.

and the hardware...

 

[Fitseries3]

ok... i used a few 2" screws to elevate the rad from the bottom of the cooler to allow good flow.

place the RAD at an angle if you can to improve/promote the convective aspect of cooling

still waiting........

spongebob FTW!

 

[Fitseries3]

rad in cooler...

 

[Fitseries3]

built the loop... filled and filling ice

 

[Fitseries3]

and results so far...

This would be a good idea. The a/c system would need to be matched (BTU's) to the amount of water or other cooling liquid used. The evaporator setting in a properly sized pool of water would be like runing a small "chiller" unit. Using copper cooling lines would further increase the abiltiy to cool. The coil on an average a/c window unit runs at around 32 to 40 (to insure no freeze ups) degree coil temp depending on abient suroundings. You can "starve" the coil to potentualy get lower coil temp. This will cause the coil to start to freeze, but in a pool of liquid it would transfer the temp drop to the liquid.
You have to remember that all things in nature flow from hot to cold. A substance will always "migrate" to the coldest point of a system. Its getting the substance to exit the coldest point is the other factor in a cooling system.
If I were to do a solution of liquid for cooling I would use a Propylene Glycol set up, but with DICE it will tend to start to gel if droped to real xtream temps. Most of your bar "beer" coolers with "tap" servers will run a Propylene Glycol cooling system along with the beer lines leading to the tap. Beer is usualy served at 31 to 34 degrees at the tap.

after it chilled down for a bit i ran a full load test.

 

[dark2099]

Are you just using 1 core for testing?

no. this chips got a funny temp sensor.

 

[dark2099]

Ah that could do it. Looks promising now.

 

[Fitseries3]

rad temp....

 

[Fitseries3]

this is a totally usefull way to cool your cpu for OCing and benching. i've been running this for almost an hour now and temps are still the same. i only put in half a bag of ice and half a gallon of water.

idle temps on this setup are as cool as my TEC block. load temps on the TEC are only a few degrees higher then idle though. that has to do with the fact that the TEC is direct die cooling.

 

[intel igent]

try tilting the RAD on an angle to see if it make's a difference

i gave it a cool 10 min try and nothing different.

 

[DanishDevil]

What you need is an underwater pump blowing through the rad's fins ^^

 

[Skitzo]

circulation makes sense, got it on the pc side of the cooling system.
That makes me wonder about putting the rad in a fountain.

WARNING!!!

you MUST insulate your board for any type of cooling that will bring temps below room temp. condensation WILL OCCUR and your motherboard, cpu, etc. may be damaged.

this should prolly be at the begining

I hope your not saying you've had a problem...


EDIT: Blkhogan are there any fluids that won't cause condensation in the pc loop using the same equipment?

lol

well kinda but not really.

after only an hour of use i had a nice puddle of water on my cpu when i pulled the block off.

i just blew it off with the air compressor and it boot right up again. no problems.
