Low profile cooler?

Hi, I am thinking of buying an aftermarket cooler, in an attempt to overclock my phenom 9950.

I am thinking of the Sunbeam Core Contact Freezer high profile cooler, although i may have some trouble getting it to fit on my motherboard with the RAM modules pretty close to the cpu (the cpu cooler fan would push air from the RAM modules side of the cooler to the rear of the case).

If it did manage to fit the fan would be more or less touching the RAM modules, and i was wondering if would be better off with a low profile cooler such as the AVC Z7U7414001 (http://www.frostytech.com/articleview.cfm?articleID=196...), which frostytech report as 4 degrees hotter than the Sunbeam at 125W thermal test.

Does the RAM give off much heat, and would you expect it to increase the temps of the cpu by around 4 degrees anyway if it is more or less touching?

Cheers
