Noctua NH-U9S CPU Cooler Review

Smaller form factor systems keep on becoming more popular. With more and more full-featured smaller motherboards coming out many people are ditching their larger towers for these smaller form factor systems. With a small form factor system you only have a certain amount of space though. This is where the new Noctua NH-U9S comes in. Compared to other larger Noctua coolers that we have tested the NH-U9S has a smaller 95×95 mm footprint so it clears RAM and PCI-Express slots on most Intel and AMD motherboards, including mini-ITX motherboards. The cooler has a height of only 125 mm as well so it makes it very versatile in fitting inside smaller cases. We know Noctua for great performing CPU cooler, will this smaller cooler fit in the same category? Read on as we find out!

Special thanks to Noctua for sending us the NH-U9S CPU Cooler to review.
