I'm at 1725 with a crap power supply (Enermax 301P-VB) and a Swiffy 462-A with the Delta 68.5cfm monster. I've gotten it to run higher (as high as 1840) but this supply can't hold the vCore over 2.00, and I'm sure the RAM voltage is dipping too low to keep it stable at the higher FSBs. Once I get a 465P-VE in here, it ought to be 1800+ with air. I can only imagine what some Vapochill could accomplish...
