I presume you're asking because you want to use your older CPU cooler on a 1366 board, then you might want to see if you can find something that adds 1366 support to your cooler. Like Zalman released new clips for older ones to fit 1366 boards. I don't think choosing a board around a cooler is the best way to go, especially when you consider the price of a 1366 system compared to a cooler or addon.
