Only the fan is not enough.
Can I immerse the tecs in the water?
Cold is measured with this, Greisinger GTH 175/PTI get -33 degrees celcius
thanks

Do you have any more pictures than the original cooling cube to get a better idea of what you've done so far, and what's going where?

And no you cannot immerse the TECs in water, even if they are the potted type, the water sealing is for protection against the condensation of water, not full immersion in water.

Hi guys

I wanted to thank you for all the input guys.
Work has taken up too much of my spare time as of late, so havent gotten around to tinker and answer on this thread.

I think I will be going for the a tec like you suggested (CTE400), thus keeping my current 2x360 rads for the hot side.

Do any of you live in Europe or have experience where to buy TEC's in Europe ?

I found a similar spec'ed TEC at Wellenctech, a Chinese company, and I might try and get my hands on a couple of samples, since they are half the price of the CTE400.

It's the one called TEC1-19928

Almost the same specs as the CTE400 ... but no graphs of performance, so I wonder if its the same as the eBay tec1 127 clones ...

Cheers Toe

Well the website link was interesting.

I've been refining my CPU overclock playing with Load Line Calibration, Vcore, Hyper Threading Enabled and Disabled, in search of running the lowest stress load temperatures I can run for CPU longevity.

I am settling on daily use of the 7700K at 5.2ghz with Hyper Threading Disabled and Load Line Calibration level 5, which allows a Vcore of 1.380v and Intel Burn test temperatures of 67c, 63c, 71c, 59c, and P95 26.6 temperatures of 58c, 55c, 57c, 57c.

That's not too bad if I may say so. rolleyes.gif

Ryan, how long does it take for your coolant to go from ambient to 10c (or was it 12c?) in Windows idle ?

My temperature controller cut out point is 8.9c and from a 23c ambient it usually takes 20 minutes to reach that cut out point, I have my temperature controller setup to maintain at least a 10c coolant temperature using a cut out at 8.9c and cut in at 10c on the 3rd TEC assembly.

But I don't have to wait that 20 minutes to use my computer because my overclock is web surfing usable at around 18c from a 23c ambient which is 5c below ambient, the operating system is not stress test capable at that temperature but for getting updates like Anti-Virus, Malwarebytes, etc., it is perfectly fine.

When I run stress tests etc. I prefer it to be down to the 10c target zone window, but even gaming doesn't have to be all the way down to the target temperature zone.

I have attempted to convey to others many times that there is CPU overclocking headroom below ambient temperature and above condensation forming, but so many have it in their minds that condensation begins immediately after going below ambient but that is not true.

My 3770K was an excellent solid example of CPU overclocking head room available going below ambient as I was not able to overclock the 3770K to 5ghz using traditional radiator water cooling, keep in mind when I am referring to a 5ghz overclock I am meaning 100% stress test stable, for trusted use on a daily basis.

During the time I was building this setup that this thread covers I had plenty of time to test the overclocking capabilities of the 3770K on radiator water cooling of which I could reach 4.8ghz stress testing rock solid stable with hyper threading enabled but could not reach even 4.9ghz, so the below ambient cooling actually allowed a 200mhz increase in the overclocking back up to 5ghz.

So to say it once more, There is overclocking headroom accessible with below ambient cooling, that is set to run above the condensation forming temperature, which has been proven with not just one but three different CPUs on this cooling setup.

The first CPU that was run on this chilled water cooling solution was a Sandy Bridge 2700K (OCd to 5.3ghz), the 2nd CPU was an Ivy Bridge 3770K (Not Delidded, OCd to 5.0ghz), and the present CPU a Kabylake 7700K (Also Not Delidded, OCd to 5.2ghz).

Thanks for clarifying. It's nice to have something to aim to for.
I'm currently in touch with Wellentech, as posted earlier and huimao, for the TEC1-19928T125.

If you do buy from them keep us informed on their quality, please?

I most surely will.
The huimao, have almost the exact same numbers as the cte400, albeit no performance graphs.

Hoping to get some samples shipped to work ;-)

Cheers
