Pros: Quiet even at full speed. Easily overclocks my I5-3570k to 4.2ghz [idle 32C/load 56C]. Installed with no problems. Kudos to the manufacturer. Well worth the money.

Cons: None.

Overall Review: Distances. You'll want a case with about 180-190mm minimum from motherboard mounting plate to sidepanel. This is a huge heatsink. You'll want the extra distance over the 160-170mm incase you need to shift fans up to clear taller ram. There's about 29-32mm clearance for RAM to bottom of the fan with the fans splitting difference for top bottom on the heatsink. Bottom of the heatsink to top of the motherboard seems to be about 51mm. A decent safe maximum RAM height is about 35mm. You might be able to scrape 38mm with some fiddling. I'd guess with the fans all the way up an absolute maximum RAM height of 40mm might be possible, but keep in mind there's a good chance the heatsink will be resting on top of the ram. You'll also need an extra wide case for this to work, or you'll have to move a fan to a pull position on the otherside of the heatsink. Hope this helps... be well everyone.
