Conclusion
Performance
The Noctua NH-D9L and NH-U9S coolers both performed admirably in testing at stock speeds, maintaining Noctua's high standards of superior performance with minimal noise. Overclocked-based performance was trickier for both coolers, especially with the Intel Haswell CPU. Neither cooler could maintain system speed and stability expectations in stock configurations with the NH-D9L only able to keep the system stable with dual fans. The Haswell-E CPU seemed better paired with the NH-U9S with its greater radiator surface area more optimized to handle the larger CPU die in comparison to the dual radiator design of the NH-D9L.

Conclusion
The Noctua NH-D9L and NH-U9S CPU coolers provide an interesting comparison to the normal super high-end air coolers we've seen from the vendor. Both feature the standard stunning aesthetics common to Noctua coolers – chromed bodies with tan and brown fans. They also feature all of the design aspects we've come to expect from Noctua – nickel-plated copper base plate and heat pipe assemblies, aluminum radiators, and attention to detail with respect to their construction. At stock, both coolers perform admirably as expected. Its under CPU overclocking conditions that shows the Achilles heel of both coolers. As discussed previously, the NH-D9L seems better designed to accommodate the smaller, hotter die size of the Haswell processor. The NH-U9S seems better equipped to dissipate the larger die-sized Haswell-E. For a small form factor build, or a build where space is at a premium, the Noctua x9x series coolers definitely fit the bill.

I feel I should point out that the phanteks PH-TC14PE is on sale for 60 dollars after rebate till the end of the month on newegg.

It always freaks me out how heavy those big heatsinks are. I’d rather go with an AiO or smaller air cooler just to avoid that weight on my motherboard.

I found this review really useful. I feel like too much of a noobie to go with water cooling so I like fan reviews.

Considering moving to one of these from a 1200mm AIO. Not many tower coolers will fit in my case (Ncase M1), and top-down would need a new motherboard with the socket further from the PCI-E slot, which I’m not willing to do until Broadwell/Skylake arrive with new chipsets. Staying inside the keepout area avoids the compatibility problems, and can get below the pump noise-floor of the AIO even with the smaller fan.

Noctua… the completely unrealistic cooler for any use in the real world, unless you don’t plan to install any PCI cards or RAM whatsoever.
