Noctua is an established player in the CPU cooler space, offering high quality solutions that cool your processors without killing your eardrums. Their U-series coolers combine unrivaled cooling performance with an innovative design to ensure quiet operation and motherboard compatibility. The flagship product of this line, the NH-U14S, is composed of a single aluminum-finned radiator with six embedded, nickel-plated copper heat pipes running through a copper base plate. For performance testing of the NH-U14S cooler, we put it up against other high-performance liquid and air-based coolers. With a retail MSRP of $75.99, the NH-U14S CPU cooler has a premium price to match its premium size and cooling potential.

Noctua built the NH-U14S cooler to transfer as much heat as possible from the processor to its massive 150mm wide radiator. They integrated six heat pipes into the copper base plate, terminating on opposite side of the aluminum-finned radiator for optimal transfer of heat from the copper heat pipes to the air medium. To facilitate this transfer, Noctua paired the NH-U14S with their NF-A15 140mm, 1500RPM fan. The fan features rubber cover plates on all four corners to minimize fan vibration and vibration transfer to the radiator, further reducing fan noise. The CPU base plate is seamless and polished to a mirror finish, ensuring an optimal mating surface.

Noctua bundles SecureFirm2™ mounting kits for using the NH-U14S with any current AMD and Intel socket motherboard. Also included are the Noctua-branded NF-A15 150mm 1500RPM fan, NT-H1 thermal paste, a PWM power splitter cable, and two sets of fan mounts (four mounts total) for use with up to two fans with the unit.
