Well if you just want something quieter, look at the Cryorig M9i. It won't overlap your RAM so no issues there and it's not very big, and is on par with the Cooler Master Hyper Evo while costing less. A bigger cooler, which will give you a more quiet fan (tho extreme overkill for your CPU) would be a Cryorig H7. It's smaller than the Cooler Master Hyper Evo, cools better, and runs silent. It also does not interfere with the RAM.
