Award-winning NH-L9i cooler
Tens of thousands of enthusiast users all over the world swear by the NH-L9i’s quality and performance. Recommended by more than 150 international hardware websites and magazines, it is renowned as being one of the best low-profile coolers on the market.

100% compatibility with PCIe cards on mini-ITX
Some mini-ITX motherboards have the PCIe slot sitting close to the 95x95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95mm sized NH-L9i provides full compatibility with PCIe cards.

Soldered interface between heatpipes and fins
With many heatsinks, the fins are press-fitted to the heatpipes. Due to the different thermal expansion coefficients of copper and aluminium, this fit can loosen over years of thermal cycling, which may lead to reduced performance. By contrast, the NH-L9i’s fins are soldered to the heatpipes in order to guarantee a superior thermal interface that doesn’t deteriorate even after many years of usage.
