Sorry I was short on my answers but had little time. To further the direct die the main point it fails is lack of surface area. With die becoming smaller the heat density gets worst. The same amount of heat in a smaller package makes cooling it harder. This is one reason heat spreaders were added and for the same reason a good water block is better than direct die. The more surface area you have to cool the better. Spread the heat through a water block or heatsink and you can get more coolant contact.
Them main reason I dropped direct cooling the IHS is there is the heat spreader is not bonded to the cores. So if there is not pressure on the heat spreader then the heat spreader is not contacting the die(s) well and thermal transfer is fubar.
Another reason to avoid it is damaging parts. to many failure points. If you are on a budget that is not something you want to work on.
Now back to radiators. I still see no reason to get a PC specific one. They are just as cheap as a heater core if not cheaper and better designed for lower pressure fans that we use. Black Ice Pro $27.95.
