Nathan Willis :
I believe he wants a CPU cooler not RAM? LOL
If you see humor here, I can only conclude that you are not aware but RAM height is a critical factor in which CPU coolers will fit. OP said was using Vengeance but did not qualify which set.... that kinda matters. In order to intelligently answer the OP's question, it is critical to know which of the two types was in use. As was clearly stated in my my message....
-If OP has low profile Vengeance RAM as shown in the 1st link, it will work with just about any cooler and his choices are wide.
-If OP has the Vengeance with the tall heat sinks, as shown in the 2nd link, the selection is more problematic and his choices are limited.
Kinda like you are buying a new CPU for a existing motherboard .... only way to answer would be to say qualify it by saying "well if ya have socket ...."

Yeah I have the second ones with the things that "look cool" Lol I didn't realize when I bought them that would cause a problem.
Yes, back in the ole days of DDR2, they actually were useful.... but DDR3 runs so cool, they are unnecessary at rated speeds. Most coolers will clear the lower profile memory which if memory serves is 40mm.
Might like this one ... works well .... but on 1155/1156

The AIOs are a workable solution but frankly, I'm not a fan as they too noise.... however the H110 performs just as well as the Noctua DH-14 and almost as good as the Phanteks.
