Summary: UPDATE 12/1/12 I ended up returning the cooler for a refund. This thing cools like the best of em' and it works great if you can get past the grinding noise it makes. Sounds like a dying hard drive. I feel terrible for customer service dealing with the complaints on this bad boy and they handled it well. UPDATE 10/1/12 "Corsair needs to improve QC" I am returning this cooling system.
Summary: I really wanted to like this, but I have mixed feelings about it. Directions-I realize that with thousands of combinations of motherboards and cases, it's impossible to write specific directions. But just a series of pictures? After it was mounted, from the moment I turned it on, the pump has growled. The web is full of this happening. Put the case on it's side, and the noise goes away. This is just unacceptable.
Summary: The fan controller does not work out of the box. The pump still works and I am getting good cpu temperatures just by putting the radiator near the 200mm case fans on my HAF-X. I am waiting for my RMA to get a fully functional system. Hopefully that will have even better temps. Corsair seems to have a couple of bad batches of these.
Summary: If you are concerned about noise then do a search on google for "H100 pump noise". You will see that lots of people are having noise issues with this. While corsair will do a rma on it this means you either dish out the full price on your credit card until the return gets there or you are stuck without your computer or with the stock cooler until you get the rma processed.
