The asymmetrical design with 5 heat pipes allows for both increased cooling performance and better compatibility. With a footprint of 95 x 95 mm, the cooler does not overhang the memory slots or PCIe slots on all Intel and most AMD-based motherboards (including µATX and ITX). Combined with a compact height of 125 mm, this makes the NH-U9S a versatile solution with excellent case, RAM, and PCIe compatibility. The included NF-A9 premium fan ensures outstanding quiet operation, with its speed being fully automatically regulated via PWM. Adding a second NF-A9 fan, available separately, can further enhance cooling performance in a dual-fan setup.
