Conclusion: First thing’s first, the Noctua NH-D14 SE2011 is a pretty big CPU cooler, as in 160mm tall and 158mm wide, so make sure your motherboard supports the girth. Once you ensure that the area around the NH-D14 SE2011 is adequate, you need to ensure that the ram modules you’re planning to put aren’t more than 44mm. Height specifications are something you can easily check on a manufacturer’s page before buying the ram you’re interested in.
Conclusion: Worries about its size aside, let’s see the NH-D14 in more detail. The base and fins are all made of copper, while the cooling fins are created from aluminum. Two fans provide the actual cooling, with one 120mm fan attached on the outside of the heatsink, and one 140mm fan in the middle of the two heatsinks.
Excerpt: When we tested Noctua’s tower-style NH-U12P in August 2009, its performance was excellent, making it a close second to our then-champion Thermalright Ultra-120 eXtreme . Given the success of coolers with one fan and one set of cooling fins, it’s logical to think that, hey, maybe two sets of fins and two fans would be even better! Thus (probably) was born the Noctua NH-D14, with its two pounds, 12 ounces of cooling power.
Conclusion: Back in the days, when AMD's Athlon 64 ruled the enthusiast market and single core processors were still the norm, South Korean-based computer cooling manufacturer Zalman manufactured some of the most popular CPU heatsink/fans around. Their signature flower design, in conjunction with a very generous use of copper, demonstrated groundbreaking performance across the board at every review website.
