Hello,What heatsink/coolers will fit the ASUS M4A89GTD PRO/USB3. Its not very clear on which ones will fit with out restricting the use of all 4 mem slots. The Scythe Mugen looks like it covers the first two mem slots. People say the hyper 212+will fit and do well. What about the Zalman CNPS9900A? Will that fit as well. I myself have the ASUS M4A89GTD PRO/USB3 mobo and have 4 sticks of ripjaws and have been using a cheap rocketfish until the fan died. I was getting a stable 31'c..I intend to OC the AMD 1090T 6x but want to be sure I have a good cooler. Im using a 932 HAF w/ plenty of ventalation. I tried the cheap P.O.C H80 and realy wasnt impressed as it crumbled apart. I haverr spent the past 4 months getting poor advice. Hope you can help
