Summary: Fits on Asus Maxiumus VI GENE, was worried about VRM heatsinks/RAM but it fits like a glove.
Pros: Lowered temps on i5 4670K by 20C over stock cooler.
Cons: Directions seem to assume that the user is installing on a basic motherboard, I had to skip the loading ring on my install due to clearance issues w/ existing loading plate on my board. No biggie but some people might not feel comfortable messing around with their hardware like that.
Summary: Overall a great cooler I have a small Micro atx case and didnt have much clearence under the power supply so I went with this cooler on my FX 8350 OC'd to 4.3. Running prime95 my temps dont ever go over 50.
Pros: Low Profile
Cons: For some MB's its girth will block some ram slots.
Beautiful and effective, but terrible installation fittings

Pros: The Zalman CNPS8900 is an extremely pretty product that indeed seems to work well as a fan in a semi-low profile environment. It comes with everything you need, including enough thermal paste for a single application (not advertised anywhere), and indeed is whisper quiet.
Cons: The fittings for this fan leave much to be desired.
Summary: If you are building a HTPC, this is the way to go. Just dont expect a full tower sized heatsink performance and you will be satisfied.
Pros: Don't be fooled by its small size. This thing can cool very well. It's very low profile and fits in my SG-05. On 1200 RPM it keeps my I7-4771 around 28-30C on idle and around 40-45C during gameplay. It was very easy to install. Backplate ensures solid installation.
Summary: In my case (Cooler Master Elite 130, with ASROCK Z87E-ITX motherboard), the installation of this cooler would actually force the removal of the included side 80mm chassis fan. Otherwise, fits my purpose well.
Pros: Clearance above the DIMM well designed, low profile (comparable to stock cooler) to fit in small m-ITX case. Quiet on low settings.
Cons: The diameters of the fins-heatsink are larger than the base plate holes, meaning if the CPU socket is close to the edge of motherboard the heatsink extends beyond the edge, which can be a problem in certain case. Also if the RPM is hight (e.g. 1500 rpm) the noise is fairly audible. Below 1000 rpm it is fairly quiet.
Summary: Seriously worth it for the Impact as it actually fits.
Pros: Small, well built and decently quiet. It barely fits on the Maximus VI impact though it does touch the VRM heatsink. I had to pull the heatspreader off the ram closest to the HSF. 78C on a 4770k @ 4.4ghz.
Cons: Uses a funky adaptor on the fan wire, having this does allow you to thread the wire through the heatpipe but it also gives you something to lose.
Summary: Was rebuilding a micro atx case unit and wanted better cooling. Old unit was in the 50s and 60s with an i5 ivy bridge with stock cooler and Arctic Silver 5. Switched to a Lian Li case (V351B) with a micro ATX mobo. Switched to MX-2 thermal grease. Great temps. So far range from 26 to 40. Was worried about fit but made it with room to spare and memory with heat spreader installed as well. Would buy again.
Pros: Easy to install. Superior cooling. Very quiet.
Cons: So far I have not found anything to complain about.
Summary: This heatsink is a no go for ASRock's new ITX motherboard.
Pros: Nice build quality. Does fit in the Silverstone FT03 Mini.
Cons: This cooler needs to be oriented correctly so the heatpipes follow the cpu die. On an ASRock Z87 ITX board, the heatsink hits even low profile memory. It will fit the other way, but with the heatpipes not covering enough of the die, it is not an effective cooler.
Pros: Quiet, nice low profile. I don't have an unlocked CPU, but I wanted a quiet replacement for the stock fan. This definitely works as advertised. I've set the fan speeds so that it remains at the lowest setting and my cpu hardly reaches 50 C, even under heavy load in a small, hot case.
