1/2 TEC 1/2 water block - Page 2

I have the feeling that you view the water as passing between 2 separate plates (in witch case you are very right)... My idea (though not well ilistrated) was to have the water running though a solid piece of copper between the chip and the TEC unit via river channels... This should be enough for a mild water OC, and still increase quite a bit with the activation of the TEC... My whole goal is to build a system that all I need to do to get extreme OCing is flip a switch, not replace an entire cooler and loop (nor run 800+W of TECs whenever my PC is on)

What OP has proposed is quite interesting. We should encourage innovation.

If I understand correctly, the idea of channels is to increase the contact area(while reducing thermal resistance) between TEC and CPU. On the other hand, the channel limits the flow in between TEC and CPU and reduces the direct thermal exchange between water and TEC.

If designed properly, it will work. rolleyes.gif

I suggest to divide the flow at the block, so the majority of water goes direct passing through the hot side of TEC, while a small portion passes between the CPU and TEC cold side.

More fancier, you could add a electronic valve to selectively open the pass between cpu and TEC. The valve opens when TEC is not enough for the heat load...

I hadddnt thought about dividing the flow... I will try to incorporate that... And you hit what I was going do head on... I was thinking you could use a drill tap with deep threads to gain a little more surface area... Also, my fear with the switch is that (with a high level TEC) the stagnant water would freeze (not to mention I don't know enough code to make it work tongue.gif)... From you sugestion, it would also be possible to have a manual switch the simply reduces flow over one end but keeps enough moving to not let it freeze... When TEC is off, most of the water flows over the entire block... When the TEC is on... The majority bypasses the CPU (with enough flow to keep the water a liquid)... I'm that this would require a prity crazy flow rate and really high head pressure

Sounds like an electronic thermostat of sorts, and maybe an "o ringed" phenolic spacer to seperate the heat transfer in the first post?????

Freezing is not a problem with proper antifreeze (e.g. Ethylene glycol).

hey guys,

sorry about leaving this thread for so long... i have been realy busy... i made a quick sketch up of my idea wile i was gone *hoping it lets me attach it*... i know that the current cooling layout of the top part of the block isnt very good, bit that was just my quick design because it was easy to make... also, with the tubes going through the bottom of the block, they would be ridged in real life, but idk an easy way to make ridges in sketch up, so i left them smooth... the black stuff would be some form of insulation to stop heat transfer between the layers of the block, and (i believe) i included an o-ring up top... the top would be acrylic (i like see through blocks, and i dont want something that would get too hot on the surface)... would this actually work?

i may make one, but its more of just an experiment out of curiosity right now

feel free to steal my ideas and adapt them... i just have one requirement... if you make one (and it works) ship one to me smile.gif
