Here is a used Noctua NH-U12S CPU cooler which I just pulled from a system with an Intel Core i7 6700.  This was designed thinner than most tall CPU coolers, to avoid blocking tall memory modules.

Noctua states that this is adequate for cooling processors that draw up to 129W TDP or less.  This cooler uses five heatpipes, a radiator and an almost silent 120mm fan that is rated at only 22.4dB.   I include the mounting bracket that fits the four holes in an Intel socket 1156, 1155 1150, or 1151, motherboard . I do not have the AMD mounting bracket which originally came with this.

I offer a 30 day return privilege and free shipping to any U.S. zip code.
