Summary: I have this totally new build and my first time buying an aftermarket CPU cooler. The thing I like best about the Cooler Master GeminII S524 is the pipes touch the CPU. I noticed the others don't do this. There may be some that do but I didn't see them. The fan is whisper quite.
Summary: This thing is HUGE, but it fits just fine in my Cooler Master 430. My only complaint is that, in my particular case, it is too large to allow a 120mm fan to be attached to the top vents, but that is not the fault of the cooler.
Summary: Pictures and videos don't do this thing justice. It's massive, and even better it came with thermal compound. The only trouble with it is the installation.. it's a little bit awkward but it works and it stays on with no issue.
