Advice on cpu cooler

[paulstung]

Hi guys and gals,Iv,e been having a few heating problems with my cpu.I,m running an I5 3570 at stock,with a prolimatech samuel with a 120mm lepa chopper fan.I'm looking to upgrade to a decent cooler in the new year.My choices so far are the silver arrow,the Alpenfohm K2 mount doom,the bequiet dark rock pro,the phanteks PH-TC14PE or the Phanteks TC14CS.My problem is the height clearance for the ram(venegeance jet black)on an Asus p8z77-lx mobo.Can any body please help with any feedback on the best of the bunch and with the clearance issue please.I was going to invest in a water cooling kit http://www.specialtech.co.uk/spshop...ing-Kit--750-RS-Series-Kit-pid-16427.html,but was told that a higher end air cooler would be a better option?

I'm running a Prolimatech Genesis on a build and it clears the Vengeance (tall) ram nicely, pretty much covers top half of my mobo. As long as you don't use the top PCI-E x1 slot it would be a nice fit...depending on your case width. Just be aware that it does not come with fans but has clip sets for 2 fans, 3 total (120mm or 140mm) can be mounted and extra clip sets are available online for a few bucks.
It made a dramatic diff in my temps all around, and made a noticeable temp diff on my top GPU.
