Noctua NH-U9 DX-4189 92mm Premium CPU Cooler

Noctua NH-U9 DX-4189 92mm Premium CPU Cooler

Noctua’s DX line CPU coolers have become a default choice in premium grade quiet cooling solutions for Intel Xeon processors. The NH-U9 DX-4189 features a larger, custom-designed contact surface for LGA4189 platforms. Based on the proven, 92mm size NH-U9 heatsink and equipped with two of Noctua’s award-winning, PWM controlled NF-A9 92mm fans, it combines strong performance with excellent compatibility for 4U systems and other space-restricted applications. The NH-U9’s direction of airflow is perpendicular to the long axis of the LGA4189 socket, so it is ideal for workstation builds where the top PCIe slot must not be blocked and this orientation is required for having the cooler exhausts towards the I/O panel. Topped off with the professional SecuFirm2™ mounting system and pre-applied NT-H1 thermal compound, the NH-U9 DX-4189 forms a complete premium quality package for quietly cooling LGA4189 based Xeon workstations and servers.

DX series for Intel Xeon
First introduced in 2008, Noctua’s DX line CPU coolers have become a standard choice when it comes to quiet, premium grade air cooling solutions for Intel Xeon processors. Thanks to their superior acoustic efficiency, they are ideal for workstations and servers that run in noise sensitive environments (e.g. audio/video production, content creation, engineering, etc.).

Customised for LGA4189
The new DX-4189 line coolers are dedicated, customised solutions for Intel’s professional LGA4189 platform (Whitley), which makes them an ideal fit for both Ice Lake-SP based 3rd generation Xeon Scalable CPUs (Platinum, Gold, Silver or Bronze) and W-3300 series Xeon processors for workstations (Ice Lake-64L).

Enlarged contact surface
At 70x56mm, the heatsink’s copper contact surface is more than double the size of the standard model. Tailored to fit the enormous integrated heat-spreaders (IHS) of Intel’s LGA4189-based processors, this customised design allows for an optimal heat flow from the CPU over the base to the heatpipes and on to the cooling fins.

Airflow perpendicular to the long axis of the socket
The NH-U9’s direction of airflow is perpendicular to the long axis of the LGA4189 socket, so it is ideal for workstation builds where the top PCIe slot must not be blocked and this orientation is required for having the cooler exhausts towards the I/O panel.

Dual NF-A9 PWM fans
The NH-U9 DX-4189 is equipped with two of Noctua’s award-winning NF-A9 92mm fans. This push/pull dual fan configuration makes it possible to achieve a level of cooling performance that is remarkable for such a compact cooler and comes close to the bigger NH-U12S DX-4189.

PWM support and y-cable
The NF-A9 premium fans supplied with the NH-U9 DX-4189 support PWM for convenient automatic speed control through the motherboard, which allows them to run near silent at lighter loads and to speed up only when necessary. The supplied y-cable makes it possible to power and control both fans simultaneously from a single motherboard fan header.

Pre-applied NT-H1 thermal compound
Noctua’s much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance and outstanding long-term stability. Having the paste pre-applied to the heatsink base ensures optimal bond-line thickness and saves precious time in installation. Ideal for system integrators!

6-year manufacturer’s warranty
Noctua products are renowned for their impeccable quality and outstanding longevity. True to this legacy, the NH-U9 DX-4189 heatsink is built to last, and like all Noctua fans, the supplied NF-A9 units feature an MTTF rating of more than 150,000 hours. The entire package comes with a full 6-year manufacturer’s warranty.
