Thanks to the 4 Dual-Heat-Pipes, 37 aluminium cooling fins with a total surface area of more than 3800cm² and soldered joints for optimal heat-transfer, the Noctua NH-U9 achieves superior cooling results that barely fall behind those of its big brother, the NH-U12. Its compact measurements and the utilisation of 92mm fans make the NH-U9 the first choice when mainboard and case compatibility is essential - no matter whether you use it for super-silent or ultra-high-performance cooling!
4 Dual-Heatpipes for optimal heat absorption The 4 u-shaped Dual-Heat-Pipes have a huge contact area with the copper base to efficiently absorb the CPU's heat. They form a total of 8 risers to spread the heat throughout the fins.
37 aluminium cooling fins for optimal heat dissipation Thanks to a surface area of more than 3800cm², the cooling fins dissipate the heat extremely fast. Both the choice of aluminium and the fins' shape and spacing allow for outstanding cooling performance even with silent fans.
Soldered joints for optimal heat-transfer Unlike many other coolers, whose heat-pipes are stuck to the base and the fins, the Noctua NH-U9 possesses high-grade soldered joints to ensure optimal heat transfer.
Screwless fan-mount including anti-vibration strips The choice of fan is all yours: Both 80 and 92mm fans can be used on the NH-U9 and provide excellent results regardless of whether silence or performance is your primary concern. Attaching the fan with the steel clips is a child's play and doesn't even require a screwdriver. The supplied anti-vibration strips minimize vibrations transmitted to the cooler and hence allows for extra quietness.
Universal fit for socket LGA, K8 & AM2 easy installation, thermal paste The NH-U12 fits Intel socket 478 and LGA 775 as well as AMD K8. The mounting mechanism using a backplate and spring-loaded screws is as easy as it is secure thanks to the detailed step-by-step installation guide. In addition to the mounting hardware, the package contains a syringe of high-grade thermal paste.
