Pros: Keeps my overclocked 4770K cool and is very quiet.

Cons: It is huge, which may block slots depending on your MB and/or case. It blocks a PCI x-16 in my ASUS Maximus Hero.

Overall Review: As a CPU cooler it performs its functions flawlessly. My main qualm is that if I can't use a second video card for SLI, since this CPU cooler blocks the closest PCI x-16 slot in my Maximus Hero VI (in a Corsair 500R Carbide case) I currently have no plans for an SLI setup, but if I ever go that route I will have to replace the Cooler Master GeminII S524with a smaller CPU cooler.
