The NH-D15 might seem expensive, but for LGA2011 owners especially, it performs as well as all the top-end all-in-one liquid coolers out there so in cooling terms it justifies its price. Even on LGA1155, which is easier to tame, it's still extremely potent, matching the 4th best result on test. Perhaps the biggest plus point for those looking to get rid of a small, whiny cooler in time for warmer summer months, the NH-D15 is also very quiet, especially so when used with the included low noise adaptors.
