it's an innovative idea, but magnetic fields in your rig is no good, and for the price (€400, a dutch etailer was the first to sell it) you can buy a kickass water setup. Which cools waaayy better than this.
Electic charges only have the capibility to warm things up. A possibility would be a concept equal to the fridge, which would cause one side to be warm and the other to be cold... It's already in use by extreme overclockers, but the beer keeps me from remembering the name of it.
