With a requests from many members at the ASUS meet, I am starting this me separate thread.
Below is the link of my Case Build…

http://www.techenclave.com/overclocking-n-modding/new-case-build-157379.html

I am just upgrading the watercooling stuff to support a TEC.
So here is my current PC

Got a TEC from a Friend.

He didn’t know about the wattage of the TEC but sure that it was a 12volt one. So I did some testing.
A test run of 5 sec with a PC PSU and amp meter on 12v line show that this piece draws about 10amps of current , and in just 5 sec of power the cooled side of TEC was chilling.
So it is a 96watts 12volt TEC.. Cool for my i7 2600K..

Now have to do something with this.. first thought of making a Chiller..but 96w is not sufficient to cool the water inside the present loop.
So thought to place it directly on to the CPU and use water cooling for hot side of TEC.
But current CPU block can’t handle 95W of CPU + 96 W of TEC totals to about 200 Watts of thermal load. So need to make a new water block.. worked whole Sunday and made this.. it’s still not complete yet.. just the socket plate have to be finished.

More Update with CPU water block.

Little finishing work and Inlet outlet holes with threading for barbs is still pending..

Just tested it for any leak with 200 psi water pressure.. And this block result no leak...

Working on new reservoir..with more coolant volume
then test it wth TEC..
More Update.
Few acrylic pieces

cutting and bonding together then making threads for the inlet and outlet barbs..

Thanks..
 
Fantastic.

Mate, try to bring some more "compactness/order/arranged/Finished look" into the setup.
 
Incredible stuff as always :)

Nice to see an i7 2600K and a HD5770. What happened to that WC HD4850?

HD 4850 sold to a friend..
 
Good to see stuff like this on an indian forum. Always been a fan of your work. Good luck with this latest project.

Have a question though, If i want to cool the water [not the cpu directly] how should i go about it? i do know a much higher W Peltier is necessary but no idea as to how it all gels together.

Would be great if u can lend some insight.

It would be a huge waste of Power, CPU temps wont improve much even when you use a much beefier TEC......TEC in itself are pretty inefficient, so cooling water which in turn cools the CPU is basically a waste of money.

I know but it will be more fun then waste...

I will sandwich TEC between CPU and Block... When fun is over TEC will be pulled out that's it.

yeah, your Idea is pretty practical man, and which has been done many times before, so you wont be going in blind. And even though if a bit inefficient, you will still be getting decent improvement in temp.
 
@banik, so its not wise to go for a TEC then?

So the only option for chilled cooling is to have a HVAC unit? Not worth the outcome i guess.
 
Looking forward to the final build, and the temperature deltas vs. stock...!

Really nice till now. :)

What Rakesh is doing is comparatively pretty cheap as a project (not for 24/7 usage IMO) and gives decent performance. You can even go till 0 to -10C with the setup of the right mix of water-cooling and a beefier TEC. Just that, you would need to use the cold side of the TEC to cool the CPU directly(ofcourse there should be a flat metal in between the cpu and tec), and the hot side would be cooled by the water cooling setup.

HVAC would give you much more better/impressive results, but I dont think any of us have the skillset to build a HVAC unit and getting it shipped from US/Europe would be mightily costly and has chances of getting stuck on customs because of the gases used.

40% parts are in the house...

Solid copper round bar will be in house by Friday.. Still finalizing the compressor.

Which gas are you planning to use??? If there is a leak and you have to fill gas how would you be doing it??? Do you have equipment for brazing??? Whats your plan for suction line???

If noise is not a concern would suggest a rotary compressor. IMO they give better performance and are a bit cheaper.

Wait.. wait Sir... all your questions will be replied soon..
 
New Update.

Finished reservoir top cover.

Cleaning of reservoir was always a problem since in due time, inner walls of reservoir accumulates water traces and if color die is used in the loop than die traces get collected, and there is no way to reach inner side of the reservoir. So top cover of my reservoir is removable for easy cleaning.

Top cover is sealed via silicon glue which can be easily replaced whenever reservoir needs cleaning.
Final polishing and cleaning of inner side is still to be done. So final product will be cleaner and shinier.
