NH-L9x65
As I have previously mentioned, stock coolers sport fans that directs air flow downward and usually cannot be reversed. These fans/coolers typically have faults: the fan has no special blade design to reduce fan turbulence, there is little in vibration reduction, and the fan speed need to be high to generate more air flow across the dissipation fins to keep the CPU cool. As evident from the temperature charts on the previous page, the stock heatsink cooler/fan provide the same cooling performance, but these faults typically mean blade and vibration noise that can detract from the stock cooler aesthetics. Aftermarket manufacturers avoid these faults by separating the fan and cooler, then adding features to enhance their version of (for example) a low-profile cooler. Noctua has addressed these issues with the NH-L9x65 L-Type low-profile cooler by eliminating an enclosure to hold the fan to the heatsink, and using the NF-A9x14 premium fan. This fan has special design features in the blades and casing to reduce air flow turbulence as well as reduce vibration transfer. With a maximum 2500 (+/- 10%) RPM speed, this fan pushes over 33 cubic feet of air per hour and is very quiet during operation.
"All of these features add up to an exceptional heatsink cooler that will help make your HTPC or SFF system operate at peak performance." (Marvin Purdy, Neoseeker.com)
