This idea is way out there. You have been warned!

Look at the following links:

See the graphic at the bottem.

So maybe one can combine Blomgren's cooling effect with De Seversky's wind effect to silently cool a radiator used to watercool a computer! Might even get slightly sub ambiant water temps according to Blomgren!

The problem is that the according to De Seversky's wind effect the radiator would have to be negativly charged with a PD of 30KV. This would cause havoc inside the computer!

I am thinking that one could have a seperate enclosure with a course mesh, 30KV negative screen mounted at the right distance from the earthed radiator. The negatively charged air would then rush towards the radiator causing an airflow and also disloging the positively charged, boundry layer, air on the radiator, increasing efficiency.

I would also have the radiator mounted horizontally with the - charged screen below it, to work with the natural law of Convection.

Its a crazy idea, but then so was flying once. :D

This is commonly mentioned as peltier cooling. It is not uncommon to use it for extreme overclocking. It does work fine, there is just a few problems.

1. Heat is transfered a very small distance, so the benefit is not enourmous, even though it does help a lot anyway. You still need something to move the heat further away, like watercooling.

2. It uses heaps of power to move the heat. Too get heaps of power you need a very powerfull PSU or possibly an extra PSU. The PSU itself needs to be cooled (usually with a fan).

Do a search for "peltier", especially at overclocker forums you will find plenty of information.
