Air -stay away from thermalright. any cooler made by thermalright manufactured or sold without lga2011 on the box itself itself is not supported for 2011. unlike Noctua who adapt their mounts properly and support their coolers routinely on new sockets Thermalright do not. They advertise they do - reviwers tell you they do - but they don't. Not 1 ounce.
Noctua will even send out a new mount at no cost. Thermalright have always charged for this.
They are the worst in the industry because they want you to buy new every time - environmental vandals who provide no genuine support to their customers.
Water - Antec h20's - 3 year warranty - good company who will not leave you in the lurch.
