To cool your RAM I have been using one of these badboys

Its a Zalman BR123 you can attatch upto 3 fans to it, it fixes onto your PCI screws and doesnt get in the way of anything but a 92mm fan will reach the RAM perfectly

Its what Im using!!

NB: Ive just found an FX53 that I may get, atleast I know that thing will work ok

Such a shame tho, this 90nm malarky is destined to fly!!
