www.cpuwatercool.com used to have it, before they went outa buisness... it was called the direct die injector cooling system (or a combination of those).
They also had one on a pelt, but the results were less than impressive.
I really looked like a swiftech waterblock (with the open inside) with the barbs at a slant, and a large o-ring.
A guy in town who works at my favorite computer store is working on direct die oil cooling. I will tell more once I get more details.
