I saw that design some months back: the guy who runs the website came here for a while.
It does work, but it is limited. You have to remember first of all that if a pelt is air cooled, then its max rating will be around 80 watts, and that just doesn't cut it anymore.
Even though pelts are rated for power, you have to remember that the heat transfer is not very efficient, so the pelt should be rated for at least 50% more than your heat source, so that leaves that little 80 watt pelt to cool a 53 Watt heat source. Also, because applying power to a pelt becomes inneficient above 85% of the max rating, you don't actually use it for 80 Watts worth, it's more like 68Watts, which would only be good for a 45 Watt source.
The latest AMD CPU is rated for about 70 Watts, with no overvoltage or overclock.
So if you use a pelt that is rated higher, you have to watercool it.
I thought about using this gizmo in a loop, but it would still have to have a radiator, and since the gizmo would bring the temp down, it would also decrease the efficiency of the rad, so it's really no good at all.
