Today I will be reviewing the Nocua NH-U9S CPU cooler brought to us by Noctua. I recently reviewed another 92mm cooler from Noctua and was surprisingly pleased with the results. As always Noctua has made the option to run dual-fans easy breezy. Noctua has hit the mark on designing every cooler with the option of adding a second fan which is a huge cooling benefit. At 92mm, that does not sound like much but when the temperatures rise and the fans begin to hum the NH-U9S cooling capabilities will come to life. I noticed on the last cooler from Noctua that I tested with an optional second fan I seen an increase of 10% cooling performance. Noctua has a strong name in CPU cooling all stemming from the Behemoth NH-D15.  Noctua has graciously sent us the NH-D15 in the past, so not only do we get to compare the NH-U9S with various other coolers, but we get to see a head-to-head battle with Noctua's best. The NH-U9S is loaded with heat-pipes. There are a total of 5 heat-pipes running through the base and extending out and up each side throughout the cooling fins. This design alone looks like a cooling machine. I can not wait any longer to see the cooling capablilties of NH-U9S!

Continuing the renowned legacy of Noctua's award-winning NH-U9 series, the NH-U9S is a premium quality quiet CPU cooler in classic 9cm size. Its asymmetrical design with 5 heatpipes not only provides even better cooling performance than the previous generation but also improves compatibility: Thanks to its 95x95mm footprint, the NH-U9S clears the RAM and PCIe slots on all Intel and most AMD based mainboards, including µATX and ITX. Combined with its 125mm height, this makes the NH-U9S a highly versatile solution with excellent case, RAM and PCIe compatibility. The included NF-A9 premium fan supports automatic speed control via PWM for outstanding quietness of operation and a second, optional NF-A9 fan can be added for further improved performance in dual fan mode. Topped off with the trusted, pro-grade SecuFirm2? multi-socket mounting system, Noctua's proven NT-H1 thermal compound and full 6 years manufacturer's warranty, the NH-U9S is a deluxe choice through and through.
