Consider a normal after market heat sink for a CPU. Costing about 30, 40 dollars. It is medium in size and has only 3 U shaped copper heat pipes with aluminum fins. With a normal fan, this heat sink can probably lower the CPU temperatures from 80 at Load to about 65 or so at load assuming no over clocking.
Now Think of a liquid cooling water block for the CPU. the mounting system is similar to that of a normal air cooled heat sink. But the liquid cooling block is really just a leak proof little compartment where water flows through. These cost anywhere from 40 dollars for a cheap one, and 90 plus for a more expensive one. Without nozzles or anything else that it requires to work.
Air is a less conductive substance than water. Also water requires much more energy to have its temperature raised thus absorbing more heat from the CPU.
If you have seen pictures of the inside of a water block, it is basically raise thin fins that water flows through. These would absolutely fail if they were used as air coolers.
Now, since air coolers are designed so that even they are able to lower temperatures using a much less effective method of cooling, then they in fact must be more efficient at transferring heat. Which brings me to my idea/point. If you can make a little box, similar to a reservoir around the fins of a air cooler heat sink, then have water running through that constantly, would that not make a better cooler than a normal water block? Assuming you have the time, tools, and materials to make such a thing, I believe you can make this and make it even more effective than a normal water block, based on my previous assumptions are true.
I would love to try this, but it requires lots of money, something that I don't have.
