Hey guys, I spent like 6 hrs getting my computer together... By that I mean searching up and down the house for the missing parts. I haven't completely finished but here's what I've got finished right now.



Tomorrow I need to hookup the aux PSU, fill it with coolant and hook up the HDDs. At some point I'll have to go to Home Depot to fix the chiller to the top of the case and put the case upright. It doesn't need to be upright to test the cooler though so I'll have some results for you guys with the Phenom II x6 1090T.

The project is looking really good, it's time for results!
BTW, I remember your plan was four TECs, but in picture I only see two of them...

Ok guys, here's the results! I only performed a 30 min prime95 test for this. Anymore than that and it's not needed. Mindchill decided on 10 mins at one point to reach saturation. Anyway

I did away with the reservior cause it leaked more than my grandpa when he takes a water pill. It has been like that from day one because of their glue job on the threads. I tightened it time and time again but at one point the thread stripped and pretty much was done at that point. I tried to fix it but it wasn't worth the effort. So I switched to a fill port style.


I didn't actually realize the motherboard would hang on to my last overclock so I was like "Why is it so high?" The 17°C that is. Then I found out I was already at 4GHz.


Moving left to right are the 10 minute intervals. The fans were on maximum for this and they are definitely loud. The most annoying part in my opinion is the Meanwell PSU fan. When I get a new Aux PSU, I'm going to hook up Mindchills TEC controller and then I'll be able to PWM control the fans with the motherboard.


Here's the details of the environment:
Ambient was aimed at the floor to show the coolest possible air being in taken by the heatsinks, but it was pretty even whether it be taken from the ceiling or floor. The next is the hot air coming off of the cooler through the fan grill. I'll definitely get an "exact" temp of the hotside when I'm finished.


And heres a 1 minute cooldown after I shut off Prime95. Took be a few secs to actually turn it off after taking the picture.
On the left is the start, on the right is the finish after 1 minute.


And here's a picture of the broken AMD CPU sensor. Also I should note, since the sensor is crap, there's an offset of 11°C in the positive that's applied to make temperatures read closer to true. Otherwise my CPU runs at 16°C on stock heatsink at idle when room temperature is 27°C.


I'm currently running a torture test of 4.2GHz on the chiller at 1.44V and I'll chime in when that's done. It use to overclock higher but I guess that just happens over time. Hope you all enjoyed!

Here's the torture test results. 40 min prime test. 4.2GHz @ 1.44V (Stock: 3.2GHz @ 1.32V). Ambient air being pulled in was about 23°C and hotside temps were about 39°C



EDIT: Ugg forgot to get a CPUz shot! BRB!

Very nice temps !

Just to clarify, you are using 4 9 amps TEC right?

These are the TECs I'm using. They should be running at about 7.5A in the worst case. 6.5A in a normal run.

You can resurrect that res by using MEK solvent cement ( methyl ethyl ketone ) . It will seal and weld the plastic together but be careful not to get it on anything else that is plastic, also have everything ready and work quickly. Keep on the great work, will be posting my build in the next two weeks just waiting on another TEC and two water blocks. cheers.gif

I don't know how to relate AMD core temp to Intel's. But nice results Krow!
Do you have a sensor measuring the water temperature?

Not right now. Thinking of shoving Mindchills transistor sensor down the fill port hole to intercept the waterflow. He sent me one for inline measurement but it only results in a zero on the display. The tubing doesn't feel much cooler than room temp after 30 mins though.

AMD CPUs don't like to be above 63°C. That's that unsafe zone. When I was using the H70, I was getting about 50°C when playing BF3 which like to use almost all of your CPU. Nearly impossible to find prime95 temps on a well watercooled AMD machine, however when I used US2's dual 50mm TEC Block, the size of it was unable to efficiently cool my CPU and it would sit around 48°C at about 22V with 2 thick triple radiators. Granted though, it was a whole lot quieter.

I turned down the fans to 50% duty cycle (~4.3k RPM) and then fans were quite a bit quieter than the Meanwell fan. Heres the actual results of a 30 min prime95. Ambient temps were the same from yesterday.



When you compare CPU Socket temperature to CPU Core temperature you can definitely tell that a water block is much more efficient at transferring the heat correctly. Very little is going through the CPU. So much so that at idle, I've only ever seen it as low as 16°C. When I used US2s block, it was sitting around 8 - 11°C at all times until the CPU got really warm.

I see. Is it two or four TECs? The picture only shows two.

I agree that water block is more efficient than TEC baseplate in terms of heat transferring. In my test I see at lease 5C difference for Intel's CPU.
I guess your water temperature during prime95 is around 23-25C. I dig out my old results for comparison. IIRC I used the same CPU and motherboard. The water was at 19C during prime95 in the test. https://lh5.googleusercontent.com/-hrvjoVqG0cI/TmP4sJPR0yI/AAAAAAAAA_Y/2nufDwblwLQ/s1600/TEC1.JPG

Nice project and test thumb.gif I always want to do this as you did but never got enough time.
