Thoughts on a possible TEC setup

post #1 of 67
Thread Starter 
Considering I am already pre-wired/plumbed for a TEC (2 heatercores, etc.) I think a move to a TEC would be prudent considering I am hovering well over 45C.

First- I would only use a TEC once I had my waterblock built that I know would be able to cool it effectively...My little Storm can't handle that type of heat load. I am in the process of designing a waterblock that can handle the size of a 437W pelt, the standard one...

Any ideas? Pinhead, can you give me some suggestions as to what you did to create your variable PSU?

I'm interested in this as well for my folding rig. Is there a TEC/WC block combo I can simply swap out with my existing CPU waterblock?

ATM, there are few blocks that handle such a heat load- I am in the process of designing some, which when I purchase advertising space from admin I'll be able to talk about some more....Until then, choices are limited- There used to be a good one, the Dominator Pro.

Oh, and Pinhead, I wouldn't like to go below ambient- Just want to cool things down some.

There is a Waterblock/TEC in one type of thing. The best one I can think of is the Swiftech 6002 which uses a 226 watt peltier.

I'm excited to see your custom TEC Burn =D

After giving it some thought: I want to get down to around 22C- That is right around 72F, or the hottest my room will ever get. I am guessing I'll need to get the voltage just right so that I can maintain the right range..Any variable PSU suggestions?

I found my PSU

Meanwell MS-300A, model 2F.
http://www.switching-powersupplies.c...es/ms-300.html

Adjustable from 13.2-16.8 V DC, and throws out 23A at peak.

Using this TEC undervolting chart, I figured that I would use, at absolute maximum, 20A- Below the maximum current of this power supply. It is able to provide 23A peak for a 30% duty cycle, or 20 seconds for every 60 seconds used...I hope that I stay well below the max current. More likely, according to the charts, the 18-14 amp range....Between 12 and 15 volts DC.

And 98 bucks! Steal!

Edit- Found out the rated current is 20A from the user's manual on meanwell.com.

Sorry I didn't reply sooner. I don't really have a variable PSU unless I take it all apart again. I built the "more reliable" one that I posted (sticky in the TEC secion). To make it variable, you basically have to be lucky enough to find three PSU's that have voltage adjusting pots on their circuitboards.

My 437w Arctic Web was able to cool right to 28°C full load, 5V to the peltier on my X2 3800+ at 2.5Ghz and 1.5v. If you don't want subzero temps, just hook the peltier to the 12v output of a spare ATX PSU. That should give you the temps you desire (assuming your block/cooling is working as it should).

If you're interested, I have the email for the guy that made these. He's still around, and does have some inventory left.

You know how to contact Devin?? Do you know why they quit selling them? The Arctic Web was the only high performance TEC on the market, and the only one even worth buying!!
