Heatsink and Fan compatibilty question

[pimptovimto]

Hi,

Ordered my kit but not decided on Heatsink fan options yet.

I am looking at either the OcUK Tech Labs - Prolimatech Megahalems Rev.C "Ultra Silent Edition"

or the Corsair Hydro H80 High Performance Liquid CPU Cooler

I have this memory on the way Corsair Vengeance Blue http://www.overclockers.co.uk/showproduct.php?prodid=MY-300-CS&groupid=701&catid=8&subcat=1390

First question is compatibilty with the Ram, will the Megahalems clear the high profile ram?

also If I decied to go for the H80, the fans seem to get a bad rep for noise, would these be a good quieter replacement fan option for the H80
Prolimatech Blue Vortex Blue Wings 120mm Fan

Also I am not going to overclock the system from the off as I have no experience of this, but it is something I want to do in the future, would both these collers do the job when it comes to overclocking

Thanks a mill
