Alright new idea, what if you take a Corsair H50/H70, use it to cool the hot side, and the put the coldside facing the Apogee GTZ block(Would be using this in line with main CPU loop).

So the sandwich would look like this...
120mm fan(For H50 rad) - H50 <-- Hotside/Coldside --> Apogee GTZ
While the whole CPU loop would be like:
MCP 355 --> Apogee GTZ(TEC)--> EK Supreme HF(CPU) --> MCP 355
Ideas on temps? If they're low then I'll definitely look into it lol.
Better late than never...
 
In terms of an idea, you're describing the basics of a chiller.  But from the specs, it won't work, at least not with any appreaciable load as intended by the blocks.  Heat from sources has to go somewhere and TEC's are limited in what they can pump unless you have many, and if you do make sure the cooler can remove the TEC heat plus whatever is being pumped through. 
 
That's the part people forget: TEC's aren't coolers, they don't replace a heatsink or a radiator, they only pump heat at the cost of running themselves.  If a unit had a Qmax of 50W and was trying to pump 100W from a source, the hotside is dissipating 150W which a cooler has to deal with otherwise the if the hotside gets too warm, then the coldside gets warm.  If instead the source was 150W, forcing 200W to the hotside, same result, the coldside gets warmer than the hotside.  The system must be balanced and many folks don't do the math expecting miracles and blame the TEC for not getting that result, which frustrates me...
 
I'd try your idea differently, say taking two H50/H70's where one should be modified with two waterblocks where one is sandwiching a TEC with another H50/H70 while the second block is on a source.  This ensures the TEC isn't removing all the heat byitself and is allowed to actually cool the fluid upstream of the source.  If you force the TEC to take it all, it isn't going to cool anything.  In terms of this idea, it's best to keep the loads going into the TEC low, i.e. don't assume this setup can now take a 6-core to 5GHz, it won't happen.   Lower the source load, higher chance for lower temps, that how it is with just about any cooler.  Ultimately if you removed the TEC, you just have a LCS with two rads, how much heat can they support? 
 
Be realistic; TEC's may lower temps if done right, but wattage levels aren't going to change except with more radiators.

Whoa.

I think you got ninja'd on tuesday  ;)
 
Welcome leph?!  We haven't seen you in ages?!
 
I am going to spend the day welding and grinding-  The Y axis is completed!!  Now the hard part- the Y.  Once that is done, comes the electronics-but that probably the easy part for me ;)

Thanks guys! I also upped a few other of my records (haven't posted them though), but my ram was being finnicky, so i stopped. Last night i just set up the UD3P with the q6600 i recently bought. Hopefully i can get some nice overclocks out of that too.

So much welding... can't see straight.  Pics tomorrow.

lephron thanks for replying here! That was pretty much my idea, only difference would be I'd add a swiftec 360 as the rad(instead of the modified H70), and use an EK HF Supreme CPU block, with a laing DDC.

A new toy:

 
A metal specific horizontal bandsaw.  That much larger bandsaw that I have is too fast to cut steel, so I just use it for copper & aluminum. 
 
I did lots of grinding and welding yesterday and instead of posting all the pics here, I'll just make a new post on welding in the general forum.  Learned lots of good stuff.

Very nice nateman. That should help I imagine.
 
@ Lephron, here's a picture of what I mean..
 

 
 
Color codes...
 
White = tubing
Black = Swiftec 360 rad
Red = 226W TEC plate
Blue = EK HF supreme
Green = motherboard
Brown = H70 block/pump assembly
Pink = Laing 18W DDC pump
Yellow = H70 Rad
Purple outline/white inside = Swiftec GTZ CPU block on TEC
 
Hotside would face the H70 of course, cold side would face the Swiftec GTZ inline before the EK block

So your looking to chill the water a bit?   Sounds interesting.  Maybe have the tech right before the CPU.

Nate, saw the welding write up you did. Nice job! I can't wait until you finish your CNC, then you can really crank out some pots. (and give the first sets free as testers to the GIC crew)

heh.  The CNC is more for motherboard, video, and CPU blocks.  I got a rotary table for pots-but I need to finish working on the table to get it up and running.  SUCH a job.  biblical.
