The Cooler Master Hyper N520 Universal CPU Cooler uses twin fans and a mirror finish copper base to achieve maximum cooling capacity. The universal mounting design makes this cooler compatible with all current processors from both Intel and AMD. The unique dual fan cooling solution keeps a consist flow of air running across the cooling fins and a dual plug cable adapter means that one motherboard header can run both fans. Five copper heatpipes extend from the mirror finished copper base to maximize the heat transfer to the wide surface aluminum fins. The Cooler Master Hyper N520 is a powerful cooler designed for powerful processors.

I bought this looking for cooling of overclocking int he future. Works well. Phenom X3 is idling at 35c and a 45c at load. Good buy fro a geed price. liquid cooling is still the most efficient way, but not everyone has the cash to shell out for that type of setup.

Easily mounted on a GA-P55A-UD4P with an i5 750. Had no bracket issues as did the previous reviewer. Maybe that one slipped through quality control? With a mild OC at 2.8Ghz it''s idling @ 28C, load @ 48C. Ran Prime95 for 24 hours...high temp was 61C... well below tJ max. Unbeatable price for a cooler of this quality. Can you get a better performer? Yes...but not at this price. I''ve even seen them $10 cheaper.

mounting hardware for the coolermaster cpu coolers is reverse threaded for the first thread on the screw. That''s probably what your problem was...

Went together without even the smallest problem. Not sure what the other review is talking about. The mounting hardware worked perfectly and held things tight. After using almost every type of cooler made. This one mounts no different. Read the instructions and things should go smoothly for you as well. And for cooling i give this cooler an A+++.

I''ll report on effectiveness after I''ve had this rig up and running a while - the cooler itself has a sweet design - but bolting it down is a bit of a problem.To hold the device to board, CoolerMaster relies on four double-threaded screws driven into one of three or four different plates and attached to the bottom of the cooler - with 4 tiny screws fitting perfectly into a beautifully machined Cu/Al block. But the steel arms for the LGA-1366, and all the other systems, were roughly punched and tapped so badly that, without a set of taps at hand, I ended up enlarging them with a reamer and holding the screws in their permanent position with ''Krazy-Glue'' -it''s like the cooler and the hold-downs were made by two separate companies! A two-fan unit on a 130-watt chip is a Good Idea! But tying together the two tach pins with a Y connector probably isn''t, and will lead to confusion on the part of the fan speed controller. Since I never allow an electronically noisy device like a fan to connect to my motherboard, and I cannot see any reason for running CPU cooling fans at anything less than flat-out, I''ll probably wire the input fan to a controller and the pull-fan to the DC fan bus sans yellow wire. If the pull fan fails, the speed of the push fan should immediately be slowed, giving me ample warning (either that or put in some switches so a four-fan controller can read the tach pins from 8 fans or more, four at a time - 4-pole n-throw where n is the number of fans running flat-out that you want to check the speed of - replace noisy fans with oil-bearing jobs or add a simple pot, or even a fixed resistor to handle speed control. NOTE on cooling I7 chips - Intel says the ENTIRE outer package of the chip has been designed to act as a heat sink. Cooling the whole chip top would be a great thing to do, but a 775-pin design should do fine until the full-surface coolers emerge. Points: 5 for cooler design and finish,0for the brackets to hold it to any chip listed, nothing a file and reamer cannot cure.
