Superb RAM. Fit perfectly in a cooler BIG! It was impossible for me to upgrade my pc with the cooler that I own because it is huge (takes the place of a Slot RAM) But I wanted to change it because it has very good performance so I took that RAM module saying bah we'll see. But ultimately disappointed the contrary. I even had room to put a temperature probe between it and the underside of the cooler. Works perfectly with Corsair 4GB DDR3 other three 1600Mhz but with "Vengeance XL" sinks that ultimately slightly lower temperature performance. Conclusion: I am happy and I advise.
