And I was worried id steal focus in this thread...

It takes 350W @ water traveling 1.5gpm for it to change 1C.

So it takes a signficant amount of wattage to pull this thing off. :T
Still don't agree with what you are saying here, there are too many other variables.

Its concerns me that you seem to have done proper testing that shows such poor results.

What do you do as a job?

Despite all this, I still think it is possible. Cathar had a good attempt at it a few years back and I've seen a few other had limited success.


I recently set up a small, very crude, testing setup I had one of these peltiers ata little over 8w cooled by a basic heat sink. On the other side I had a poor water block and a pump rated at 27w but that i measured to draw more like 20w.

I know not all 20w of the pumps heat went into the water, but people generally reckon 60-90% will, and when I put the pump alone in a small loop with a reservoir the temp rose at a rate to suggest it was dumping around 16w.

After all this the water leveled off at 1-2c under ambient. Now, I may well have missed something and all you concerns worry me, but how can I have managed results like this in such a poorly optimised test platform?
