I've been dreaming this thing up for a while now. It will probably take even longer to dream up the funds. I'm planning on purchasing a new Full Tower Case and using all of my existing parts from the Unicorn Project and building a peltier system. My idea is to get the case temps down to around 50 degrees F, by Using a peltier and running a water block and radiator on the hot side and a water block on the cold side recirculating water from the res to the pelt and back into the res. I'll do this with a high flow pump. I'll then draw water off of the res via a low flow pump, through an internal rad and have it blowing into the case at low flow. My thinking is that the high flow pump will pass the coolant over the pelt about twice as fast as the pump cooling the radiator, for even cooler temps in the case.

WHY????? I don't want to get into sealing the mobo and components and I'm not looking for super cool temps. Just pretty cool in more ways thasn one. I'll use low noise fans and with the right case, there will be an intake fan on the bottom of the case and the one exhaust fan feeding the Hot side rad some cool air. Again, I'm new to this and I'd like to design a system that has either not been done, or rarely been done and is effective.

Check out the design and let me know if this thing will even work. All I have for design is MS Paint, so sorry for the sucky pic.

By the looks of it, it seems you want to cool Air with it, Correct? Its a cool idea, but dont forget the power requirements of the pelt. Wouldnt it be easier to have a Heatsink to disipate cold air instead of a water cooling system?

I was thinking about the surface area. It would have to be a pretty big heat sink to be as effective. I don't think it would move nearly as much air either. I'll have to think on that one for a while. Somewhere in this mix will be a second PSU just for the pelt and possibly the pumps.
Thanks for the thought!

I don't think it will be effective or efficient. For under a $120 you can
buy a small window AC unit and duct Cold Air into it. Plus you'd look
like a "Mad Scientist" :-)

You'll need at least a 400 watt pelt just to cool the cpu heat heat load that way,triple it for the entire system.
Also you'll need to seal and insulate your case to make it efficiant

I tried this with a water loop and 4 - 80 watt pelts it lowered the temps 4 degrees
Its just so terribly inefficient,but it can be made to work.

Heres some commercial peltier airconditioners.
They start around $1000.00 for an 800Watt dually
Thats the minimum you'd need to effectively cool a singe Gpu system down to 50f (Maybe)

That sucks! I guess I'll move the machine to the bedroom where my window unit is and go w/Slaymate's option. Thanks for the input though. NEXT DESIGN PLEASE!

Well how about this: Mount the pelt over the CPU fan (the cold side) so when the fan sucks air inward, it will be sucking cold air.

But why???
Your just adding another step into the equation,and totally ruining the allready poor efficiency.
Also it'll frost up the pelt and condensation will drip off eventually.

If your gonna go pelts, they belong directly on the chips with water cooling to take away the heatload.

I tested it, and though it does have some merit, the money would be better spent towards a good watercooling system.

I tried to get them to make a few changes on the original version , and if they would have followed my ideas more closely on the newer version, it might have been kick ass...but they only went halfway, ending up with a mediocre product.

If you are serious about doing this, let me know...

Yup, I bought a thermaltake air cooled Cpu pelt much like that a couple years ago.
It uses an add in card / powersupply that draws 110volt power from the wall socket.






I wasnt at all impressed with it.

It did work but...
I ended up running a tornado fan on it and relocating the temperature sensing thermocouple then it was much cooler.
But never more than 10f below ambient

But after hearing stories of fused thermocouples and Roasted cpu's i took it off
So into the drawer of useless pc junk it went.

Hmm wonder if I could get this onto a GPU ...

I was dead serious about doing this setup. I'm having to wait a while and take care of some financial matters, but I was hoping to get started in October. After hearing the input, I just don't hink I can afford the setup it would take. I had figured on around doing this for just under 500 bucks.
Case - 50
Pumps - 150
Pelt - 50
2nd PSU - 50
Res- 35
Rads - 80
Fans- 50

Seems like a waste now that I really look at it. I just did not want to get into a pelt system and all of the insulating that goes with it. Thank you though!

Heh, I had bought one of those about 3 years back. The fan on that POS stopped functioning after a few weeks and fried my 2.4C, I came back and found it practically melted the socket to the chip.

I got into a system surronding this matter a littlewhile back, but i got it to work efficiently, even with high airflow through my case

I used my already running water loop, added a copper block, then added my TEC (80w), then to run cold air off the TEC i ran a small pentium stock cooler with a somwhat quiet fan (30db max)

after testing a few different ways, and running a transformer type power for it, the transformer needed cooling or it would overheat and cause the TEC to fail, so after putting the transformer into my WC loop case for the airflow to cool it, it took about a week to set up

i got inbetween 1C -5C drop in ambient, now when the room air was in the lower 70's it worked better and the air getting higher up to the 90s (summer came) the temp difference was minimal

Now i have lots of MSpaint Drawings that could work with alot of help and design, but couldnt be effective after all is thought out and done

one quite well performer was the acrticweb cooler but sadly the company making it went under, but not only was it good but it needed a 437w TEC to work really well

With my 2 TEC's i plan on cooling my CPU and cooling the TEC with a water loop thats chilled to get some bench results, but having that system you said would also add condensation to the res meaning the nicce insulation is needed, but you biggest miss on that solution was the meanwell, and the 500w+ TEC

Im pretty sure you were looking at the TEC that frozenCPU sells thats 437w, best off buying about three of them and three meanwells to power them, then just getting a custom heatsink made to mount across the bottom of the case, and adding a few lowspeed fans to circulate the cold air, but even then youd need a massive waterblock and alot of cooling power foritself to cool all three of the TECs

to quote a fewi've talked to about TECs

"TECs are a PITA"

And by the time you buy all that hardware, you could have almost bought a phase change set up and had some REAL cold CPU temps...being "Different" is expensive, lol
