Had a few thoughts, related to watercooling, but using some pelts in there too, let me know if any of them make sense.

Thought 1 :

Before the CPU waterblock, water goes through a block mounted on the cold side of a low powered ( 40-80W ) peltier, hotside aircooled.

Would this drop the temp of the water by say 2-3 degrees, just before it enters the block? If so, wouldn't this give better temps, and be reasonably simple to implement?

I know that a peltier in this range, if mounted directly onto the CPU, would be a disaster, its not powerfull enough.

As I see it, the main advantage of this system would be that the pelt would be very easy to power, probably enough to use the PC's own PSU, if it was a good one.

Thought 2 :

A slight modification of the above idea, but with a more powerful peltier ( 176W or so )

The water would go over the cold side just before entering the CPU block, and the hotside of the pelt would be cooled by the water coming out of the CPU block, before it went back to the radiator.

Basically, a waterchiller, but using only one loop. Condensation wouldn't be an issue, the water wouldn't be cold enough, and again, it would be very simple to implement, 2 standard maze blocks would be prefect, and it would be a very simple matter to get enough clamping pressure to run the peltier in a very efficient way.

Would either idea actually work?

[EDIT] Rayman2K has already posted the first thought, so ignore first Thought above. [/EDIT]
