want to get TEC
 

can some one post a good page that shows the basics and all the information of soemthing like this.. thanks

Hi,

We have tutorials on our website.. We're still working on them but there is still a lot of information there. We can also answer any questions you may have.

We have simplified the peltier installation process by powering the device from a standard ATX power supply. An Enermax ATX PSU is capable of powering both the TEC and the computer components. Alternatively a second ATX PSU may be used to power the TECs alone. In this case an ATX starter cable is added which ensures the second power supply (and TEC) is powered only when the computer is switched-on. Check-out the tutorials at:

I read it, you forgot to mention to w/proof the pins on the back side of the mobo!

And only 130W TECs - bit weak for an overclocked cpu, expecially with newer cpus hittings 100+W stock.

Here is alot of info and projects: http://www.overclockers.com/topiclis...1.asp#PELTIERS

thanks for everyones input... i think i pretty much know how everything works.. kinda...

i was thinking about gettin this PSU.. http://www.excaliberpc.com/product_i...oducts_id=1998

i wanna run 2 pelts.. one for CPU and GPU... what 2 pelts you think i shoud use?? prolly going to go with the 2.4c or 3.0c CPU and 9800 pro for the video card....

you think that PSU will be good enough? is there any cheaper ones i could get?

also i was just going to go with water cooling my system.. until i came across this site.... so i already had water blocks for my cpu, video, and chipset... my question is since im going to be cooling the pelts now should i also watercool the chipset? or is the water going to heat up the chipset? im going to be using the black ice extreme radiator with 300gph...

any suggestion? thanks everyone

Get a dedicated 12V supply for your TECs - it'll work out cheaper than an ATX.
CPU - 172W or higher.
GPU - 80W or higher.

I'd skip the chipset - you'll want the water flowing as fast as possible with the sort of heat two TECs dump in the loop.

where can i get a PSU from?? can anyone suggest one to me?.. i was thinking about getting the 236 or 226W pelt for the cpu...

The cheapest place to get a PSU is from E-Bay. Look for an appropriately sized PSU for your TEC (i.e. a 12V 30A Meanwell, or a 24V 15A Meanwell, etc...). Pick the PSU based upon your TEC, of course. You should know what the voltage and amperage are from the sale literature. If it is a the 226W pelt that Dangerden sells, it lists it as a 24A 15.2V(max) device. Run it at 80% of V(max) which is about 12VDC. The Meanwell S-320-12 supplies 25A at 12VDC which should be enough, and Dangerden sells it for about $118. You can probably get it for cheaper on EBay, but you it's more risky (Dangerden isn't going to stiff you or give you an abused product).

The reason not to go above the V(max) voltage is because the resistive heat generated starts to become more of a burden than the extra cooling you get from the extra power. There is a curve where the maximum power is moved and it drops off on both sides. Most TEC companies seem to recommend about 80% of V(max) for maximum power moved.

Now, that's all stuff I've gotten from sales and engineering literature. I am not a TEC tester.

Good luck!

Max power moved at at or just above Vmax, most TEC companies recommend 75-85% due to much greater efficiency at these voltages. In many cases you get a colder coldside at 80% than 100% due to less load on the cooling system.

What you have to look for in a PSU for a 226W TEC is Amperage (+12V @28A or more), not only Watts or Volts, since these suckers do swallow a lot of juice. The pelt I have in my system, a 226W pulls a steady 15-16 Amps when measured directly, add to this another 10 Amps from other computer hardware, and you will get a figure of what you need.

Presently I am using a little gem of an ATX PSU, the Sparkle Power 550W, rated at +12V @ 36Amps, that is powering everything except the water pump.

Edit: Needless to say that if you use an under rated PSU (Amperage) you will burn it in a tizzy, and probably damage other components of your computer in the process. I know this by first hand experience!!

With graphics cards and cpus getting very power hungry, I'd really recommend a separate PSU for a TEC.

sparkle psu sounds pretty good... with the 2 pelts im going separate psu...

another question.. how do i make sure i only run %80??

thanks everyone!

80% of Vmax gives roughly 80% power. So for a typical Vmax = 15.4V TEC, you'd want 12.3V.
