I was up at 3 am and it took a while to get home like 3 hrs then all the testing. Figured the pic was the quickest way to reply until I could sum up well more like a sub total lol.

Yes it is indeed pulling the cores down sub ambient under 100% load. I haven't tried to lower the vcore yet. Running 4.2 GHZ prime stable at 1v would be interesting. Hyper Threading ON yielded an average core temp of 25.5c. This run (HT OFF) yielded 19c or less depending on which software you want to look at. In the end it's 6c lower hottest core or average of the cores which is why I said the average is of more importance to me. That one core can spike 2c for 2 seconds in a 30 min run. So depending on which system you want to use it is at least 4c under ambient.

I am happy with the fact that the TEC's can run off a single 600w Mean Well @23v. Wasn't positive it would work but it does and does so well. This allows me to continue easily onto the next part where I make the chiller and try that which can now be run off of the newly spare Mean Well. The plates are flat but fortunately I have 2 dead TEC's to test mount with. So the second set of CT TEC's will be used in the chiller.

So I really need to get the AMD rig up and running to replace the rig in my sig as my 24/7 rig well and it kills me to see it just sit there. I am going to have to get it it's own dedicated cooling. SO the 2 pumps I mentioned will be used for that. I will be using 2 of these instead to pump the chilled water from the cold side:
Swiftech MCP600's since I have them layin about.
Technical specifications
Nominal voltage
12 V DC
Nominal power
9 W
Motor type Brushless, microprocessor controlled
Maximum head
3.2m 10.5 ft
Maximum discharge
700 L/HR - 185 GPH
Rotational speed
3000 RPM
Connection size
½" barbs
Electrical connector
Molex 4 pin
Weight
1.4 Lb (650 gr)
Motor casing material Aluminum
Insulation
E Class
Our noise measurement (non lab environment) 31 ~ 34 dbA in a quiet room @ 1', after 48 hrs of operations

As I promised Krow your pics will be up tonight when I get home. Battery in the camera went dead yesterday. But to answer your question yes it should make a fairly even layer across the entire IHS/bottom of the block. Like I said I needed to remount anyway so I can reapply the torque to the screws if needed. I may just pull it apart and get the TEC's perfectly centered and/or swap the second set in there for testing. *Shrugs* we'll see how motivated I feel.

*Note* Lapping the CPU in this application would most likely show a slight decrease in temps. Anywhere from 3 to 6c maybe more depends on your lapping skills.

Feel free to ask for whatever information anyone may want (not specifically directed at Zip) I'll do my best to answer any questions as well as run whatever tests people may want run. OCCT is a favorite as it gives all kinds of charts at the end. If I can't answer it I will point you toward Zip or Ultra as neither one will answer my questions at this point

Technically there is not a whole lot different from a specification standpoint.

Hebei TEC's

263 couples 300 Qmax 31.5V max Input 16 amp max draw max temp 225c. Made in china.

Custom Thermoelectric

263 couples 331 Qmax 31.5v max input 17 amp max draw max temp 125c. Made in USA.

Now I really can't say much more about the Hebei TEC's because I never really had a working set to test and the chart looks like it was written with a bloody chicken foot TBH.

Lastly, the CT TEC's are drawing cumulatively less than 25 amps at 23v which I figured would be about 11 each or 22 amps combined or so. I really need to borrow an ammeter from work. If they pulled any more than that it wouldn't be possible to run them off a single 600w 24v 25 amp Mean Well. As it is there is no noticeable signs of strain on the mean Well while doing this. No hissing no squealing and the temps on the discharge of the fan are not all that warm all indications of a non issue rudimentary as they may be.

Now on another note. I test mounted the chiller with two dead Hebei TEC's. Works fine. TIM spread looked good. There are only 6 screws for this but they are larger than M4 and are 8/32 (6/32 being the closest non metric equivalent to M4) I used around 5 pounds of torque per screw. I need to dig more...I needed to square away a friend across the pond today so that I can now move on with the mounting and testing of the CT TEC's.

Lemme guess you are from Germany? Nope says you are from USA. Why would you want to test this on such a low flow system? Just curious you may have a valid reason for asking
