Pros: Super fast with great compatibility. I really like the Corsair RAM.

Cons: After building three computers using Corsair RAM this is the first time I have had an Issue. The Heat Sinks on the RAM make the sticks about 1/4-1/2 inch taller resulting in not being able to use my Noctura NH-C12P fan. (the RAM is too tall and the cooler wont fit). Aside from 1 of 4 sticks being bad this is good RAM, though a bit bulky.

Overall Review: I was pretty disappointed about not being able to use my cooler. The bad stick is a hassle to replace by mail. Though its a great product.
