The cooler’s installation requires an unobstructed space of 151mm(L), 132mm(W), and 155mm(H), with the CPU as a central reference point. Please check if components such as ODD, VGA and PSU protrude into the required space. If the RAM memory’s height is over 40mm after inserting into the RAM slot, then 1 RAM slot cannot be used due to obstruction.

Powerful Cooling Performance
Optimally designed aluminum fins disperse heat away from the CPU via 6 of high performance heatpipes by utilizing I.H.D technology, while the high capacity 120mm Triple fans quickly cools the heatsink for stable operation of high performance CPUs.
? I.H.D : Interactive Heat pipe transfer Design
Ultra Quiet Triple Blue LED FAN
Switching noise eliminated 120mm Triple Fans incorporated for ultra quiet operation and blue LEDs for cool aesthetics.
? ‘Switching noise’ is the high frequency harmonic noise that can result from voltage regulation.
VFP Dual Heatsink
Optimized dual heatsink, applying V.F.P(Variable Fin Profile) technology, maximized it’s performance through dual air-intake structure that increase Air Flow.
As applying W-DTH(Whole-Direct Touch Heatpipes) technology, heatpipes in the Base Cover touch the CPU directly and transfer the CPU’s heat directly to heatpipes, thereby minimizing heat resistance and maximizing cooling performance in a short time.
Composite Heatpipe applied
By utilizing Composite Heatpipes, the heat transfer capacity enhanced by 50% compared to the ordinary Sintered-type Heatpipes.
? Composite Heatpipe : Featuring a ‘Sintered Metal’ type wick, resulting in outstanding capillary pumping performance, and a high thermal conductive design of ‘Axial Grooves’ which increases the heat transfer rate.
Black-Pearl Nickel Plating
The entire heatsink of CNPS12X is plated with ‘Black-Pearl’ Nickel for a long-term corrosion resistance, while the deep “Black-Pearl” tone along with the high intensity Blue LEDs reinforce its powerful aesthetics.
CNPS12X accommodates a broad range of sockets including Intel’s upcoming socket LGA2011 as well as AMD’s sockets.
Moreover, thanks to highly optimized heatsink design, CNPS12X is able to be compatible with a Mid -Tower Case with its width is 180mm or wider.
High Performance Super Thermal Grease ZM-STG2
The included all new high performance thermal grease ZM-STG2 maximizes heat transfer from the CPU to the base of CNPS12X for intensified cooling performance.
Middle Case Support
The cooler’s height is 154mm, and it can be installed in Middle Cases which measures 180mm in width.

Got this on sale. It keeps my LGA2011 CPU quite quiet and cool. Installation was very difficult though since it covers the first slot of each DIMM bank. I had to trim my Mushkins a bit to get it to fit. If you do get this, I recommend only buying low profile RAM sticks.
I bought it for my son new build but i couldn't use it cause he got high heatsink RAM sticks. The only way to be able to use it would have been to put an 'X' on dual channel by using the two far slots for ram (don't give me dual channel on is Asus M5A97 r2.0)
I'm keeping it for my own next rig . wooooo
The looseness really bugs me and the size is troublesome. Installation was somewhat difficult, though as I haven't done a build since LGA775 that may be common to 1155. Temperatures seem great, on an i5-3570K at 4.2GHz I get 30-35C idle and 60-65C load with MX-4 paste; keep in mind Ivy runs hot, and I don't know how well other coolers do--this is the only one I've actually owned for this CPU.
