Playing with TECs. *pics* - Overclock.net

**Mootsfox** · 04-21-08

As some of you know, I recently bought a couple hundred TECs. Heres me playing around with one of them.

Using this setup at the moment, 650w server PSU which I had to mod in a molex connector. Works great, but the twin 40mm fans are LOUD.

Power usage

Sadly it only draws about 45-50w (PSU by itself pulls almost 20). However...

...It can still freeze a small amount of water. This mounting setup only has a center center of maybe 8mm radius contacting the plate I use to cool. A better mounting system should show better results. Notice how close the hot side comes to not fitting.

Lastly, just a shot showing how it's mounted.

Any comments, suggestions? I want to buy higher powered TECs and do the same thing as I have here. I also need a better cold side mounting plate. Any ideas or product suggestions would be GREAT.

How much did each cost?

Very, very little.

The TECs aren't insulated? They are open junctions? Be careful of condensation between the junctions then.

I was a bit worried about that myself. When I was cleaning some of them, there was thermal paste all up in there. What is a good way to insulate the TECs?

I've seen neoprene used to insulate the TECs. I have yet to play with one, but I am getting interested!

wont work very well theres no cold plate and no pressure applied to the TEC via it

well there doesn't look like there is a cold plate it could be frosted up in the pic

still it's all good

I see the junctions exposed in that picture though... are sure they are insulated or filled? It's gonna suck if those junctions shorted.

There is plenty of pressure where it contacts. Like I said, only that circle in the center actually makes contact though.

They are open. I plan on using some neoprene like ericeod mentioned.

Neoprene around the TEC won't help the junctions inside? Fill it with thermal paste....
