That would depend solely on the block that you buy.
I am aware there are universal blocks, but these require alternate methods to cool the memory and vrm, don't they? This is why so often full blocks are recommended, isn't it? I'm not totally adverse to the idea, but you have to admit there is a cost associated.
As it so happens, I got impatient and just bought an XFX 290 w/BF4 from Newegg with the 5% off code. $379, plus I will resell the code. The saving, plus the cash for the code will almost pay for the Arctic cooler when they come back in stock, if necessary. I guess I will find out for myself how loud the cooler actually is.
