i fitted the same configuration as you last night and it was a little tricky. In fact very! Had to take one exhaust fan off and put at the back and install heatsink vertically with only one fan near the back. If using a second one, youd have to take out the other exhaust fan and move your ram about. So now mine draws in at the back and then in through heatsink fan and then out through second fan! Its the only way but this is better than going for the hyper 212 plus as this is the latest tech from Coolermaster. Good luck
