Wondering how it performs when you keep the radiator in the loop.

Replaced them TEC's with 3x120W running @ 12V.

Specs:
123,2W

1 x 40 x 40 x 3,6mm peltier elementen

Imax= 8A
VMax= 15,4V
QcMax= 71
Tmax= 67
(127 couples)

afmetingen: 40 x 40 x 3,6mm (L1,L2,H)

35 gram

No improvement!

TEC draws +6A @ 11,9V during at start, makes 71,4W or more.
Then temps start to drop, after a approx 2 minutes I have 5,19A @ 11,92V: 61,9W.
After 5 minutes I have 5,12A @ 11,92V: 61W.

well it seems CoolIT already found a balance regarding what TECs to use, more doesn't mean better in this case

I'm not sure what to think as one of the TEC's has died on me today and I'm not aware of what killed it. Hot side temp? Without the pump powered on the blocks freeze tight in just few minutes so I know these other two are still functioning well :)

overheating on hot side could be the cause

CoolIT TEC's test: 10,82V and 1,93A makes 20,90Watt per TEC, tested on dedicated PSU.

Another interesting fact:
no-name TEC tested on Xigmatek Thor's Hammer cpu cooler, actively cooled we got 11,93V and 7,55A: 90,07W. Passive cooling gives 11,93V and 6,73A: 80,28W.
