Post Rad Chiller Concept

It really depends on the C rise from ambient that the heatsink has, and how much air is being passed through it but I'd say the temp would be atleast 10C higher than water more likely 15-20C. I suppose that really depends on heatsink surface area and volume of air blown.

If he did not cut down the heatsink, it should deliver better than .04 C/W with good airflow (1100 LFPM or better). That's not quite as good as the best water rig. You will see a 10C rise for each 250W. The better rads will show 5C for 250W (.02 C/W) with good fans and flow rates.
