Works When Installed Correctly!

I bought this unit in July 2012. In October 2014 the pump failed. Corsair replaced for free with current upgraded model. As of June 2016 it is working perfectly. My only complaint would be the instructions with the new unit. They left out important info as to the orientation of the bracket. I installed it incorrectly and temps went through the roof. I finally figured this was the problem and once correctly installed it worked perfectly(water block was not fully contacting CPU).
