Pelt Cold Plate

[Silver]

Well, I went ahead and ordered the power supply (Pyramid PS36KX - $118 shipped) and a 226 watt tech. The question is what thickness on the cold plate? I really have no idea. 1/4, 1/8 seems a little thin. Input please.

Assuming your cold plate is copper....1/4 inch would be
fine, but 3/8 inch would be optimal. Any thicker buys
you nothing.

I'd vote for 3/8" myself also. That's what I've ordered for my new blocks (on the way from my friendly local machinist/pal).

Another vote for 3/8". 1/4-1/2" is ok to.

Recognizing the level of expertise exhibited here, I am off to purchase the cold plate. 3/8 it is. Thanks guys.

Done, metals on line for $13. 3.25x2x3/8. Thanks again. Hoot, if you see this, it is going on the maze2 with a 226 watt tech.

why dont u just get the maze2-1?

You can always add a coldplate to the Maze2 just like a 2-1. I took a Maze2 and drilled 4 holes with my drill press in the same place as the mounting holes were on the 2-1. Everything was fine until I got to threading the second hole. I broke my tap leaving it in the block. To bad because it would have been exactly like a 2-1 after the modd. I have a Maze2-1 and I didn't end up using that block on the system I was moding it for so no harm done. I think I'll have to get some of that 3/8" copper now. I used my coldplate for the waterblock I made Stompah.

that really sucks..
im gonna chance my like with the new cpufx Silver plated 1/2" Z4.. looks awesome..

How about skipping the threading all together and drilling straight through and using a screw through the entire block. Should work and will make the block useful once again.

Bought it off of here and besides, I knew that the 1/8 maze 2/1 plate did not give me much in reserve on the plate. This is to say that with a 220 watt I knew they were using thicker plates, just did not know how thick.

Plate thickness should not depend on TEC power unless the high-power TECs are bigger in size.

Thermal drop through a metal is linear. There will be an optimal plate thickness and it will be the same for all wattages.

Of course, you'll still get a bigger thermal drop for higher wattages. That's the price you pay.
