Topic: cooling projects

ok, so im making the move to liquid cooling.  

i have a sweet idea with using a very power peltier in stead of a standard radiator setup most normal people use. how a peltier works is basically when you apply current to it, one side gets very hot and the other side gets very cold, the colder you make the "hot" side the colder the "cold" side gets. so the idea here is to attach a water cooling block to the cold side and a heat sink to the hot side (to cool off the peltier). the water block side will be in the water loop that connects to the water block that cools the CPU. i did something similar at home already and this thing got ice cold in seconds.  but the only problem with that is condensation. so im deciding to build a unit out side the computer to reduce condensation inside my pc.

my shopping list is below and the project will cost just under $200. which is about the cost of a standard water cooling setup. so i will be getting hopefully sub 0c temps for about the same price. and most likely be able to run my quad @ 4.0Ghz or higher if the chip is from a good wafer. yes thats 16Ghz of processing power!

hopefully i will be able to acquire these items in the next few months, pictures will follow along with better 3Dmark06 scores.

you are still gonna have to provide the cpu area around the m/b.front and rear.anytime you add cold to heat you get condensation.you should also insulate the tubing as it will also sweat.also you may need a standalone powersupply for the pelter.click on your link for the pelt and at the bottom of the page where "Customers Also Bought " and think about getting what they got.

If you care to shop around, might I recommend this pump instead.

I had a guy in my dorm last year with a whole Swiftech setup...and the thing was eerily quiet thanks to this pump. Also, these things can apparently take a lot of crap, which is something you might want to consider in a custom setup.

thanks Darth, i am going to use a variable resistor to control the voltage to the plet and the fan that cools it so i don't freeze the area around my CPU. as long as the liquid is just above room temp i can run it 24/7 with no condensation issues. the sub 0c temps i would only be for benching and not a every day thing.

and to Dave, i was going to get that pump. but.... the other one im looking at is a AC powered one, has way higher specs and makes less noise. the AC part is really good to because that will save all the current for the mammoth pelt im gonna use on a dedicated power supply. the PS im going to use is my old BFG one it still works and kicks out 14.2-14.8v @ 20amps and 5.5-6.2 @ 58amps. just not on all the plugs lol  . i think one of the rails went out on it and that why it wouldn't power my mobo. but still kicks out some serious power.

but as i said im not getting this stuff tomorrow so i will still be looking around for more reviews on other pumps. the only thing im dead set on is those water blocks.... they look sick!

this lil thing, with 2 wires can do subzero cooling  wat da... man that is just weird... how are you going to do that??? 

seems a vry nice project though
also. what is the quad you got??? Q6600??? QX9775  4GHz is crazy...

*EDIT*

is that phase change coolin? 
lol i,m so lost

It's Peltier (TEC Coldplate) cooling. Most Peltier air cooling systems work better than air cooling, but not as well as conventional liquid cooling. A custom liquid Peltier setup should be the best thing you can get this side of oil submersion or liquid nitrogen cooling. 

[LC0g]

ok so water cooling will have better perf than Peltier... and again another question: the peltier takes the heat from the CPU to the other side of the ''block''. then the other side of the block is cooled. Is that it?

no, water cant reach ultra low temps just by being air cooled. a pelt on the other hand can create ice just by having a 12 volts and a heatsink, so the idea is to combine the 2 ideas for a quite super cooling system.

yes, the way most ppl do it is they place the plet right on the CPU and use water cooling to cool the pelt. the way im going to do it is kinda like a standard water setup, only i will be replacing the radiator with the peltand air cooing the pelt. this way i still have something thermally conductive attached to the CPU in case anything dumb happens. peilters are not very thermally conductive when they fail or are under powered. but in the event of a failure the pump will still be pumping liquid thru the CPU water block and still continue to cool off the CPU for a period of time. plus i think the unit will be more efficient as heat will be dissipated thru the hoses before they even make it to the pelt. the hard part is going to be getting the liquid to stay just above room temp to avoid condensation. that will be the key to having a system thats usable all day every day verses having a bench mark machine that can only be run for short periods of time.

ok so the peltier bolck will cool the water.

where can I get liquid nitrogen cooling?

thats the idea. ill hook a water block to the pelt and use it to cool the "water" in stead of a radiator.

It's a two-way street, though. You'll also have to worry about the cooled liquid warming back up a little before it reaches the CPU block. And of course, with half of the liquid coolant tubing running COOLER than room temperature before it hits the CPU water block, that whole stretch of tubing is liable to cause condensation, as opposed to a little area around the cold-side of a direct CPU peltier block.

where can I get liquid nitrogen cooling?

You probably need to have connections with a lab or some kind of chemistry faculty on a university campus.

ok soinstead of a radiator and fans, you'll put a peltier block... is that it?? 

would it be better to put the cold side of the peltier on the cpu and cool the other side with water?? like that your CPU will run colder and there will be no condensation...

*EDIT*

wich will give you a cooling system like this

[anomaly]

yes thats it.

no, i don't want to do it that way cuz im not trying to void my mobo waranty buy making it condensation proof. thats why i want to do it the way ive stated. and the kit you linked me to is very nice but costs just as much as a phase change unit.

its a lot harder to manage temps right off the pelt it self (when seated right on top of the CPU) as temp changes are drastic. where as the delay of the water changing temp will be more gradual and make room for more error so i can manage the temp with the variable resistor to maintain temps just above room temp to avoid condensation.

by having it in a cooling loop im taking a lot of the dangers outside of the case
