CPU chladič Noctua NH-U9S – 92 mm ventilátor, 95×68×125 mm chladič, 2000 ot/min, 78.9 m³/h prietok vzduchu

The Noctua NH-U9S is a compact, high-quality quiet CPU cooler in a classic 9cm form factor. It features an asymmetrical heatsink with five heatpipes and a 92mm NF-A9 premium fan, delivering efficient heat dissipation in a small 95×95×125 mm footprint that improves compatibility with RAM modules, PCIe cards and small form-factor cases. The cooler includes Noctua’s SecuFirm2™ multi-socket mounting system, NT-H1 thermal compound and supports automatic fan speed control via PWM; a second optional NF-A9 fan can be installed for increased performance.

Advantages

The NH-U9S combines compact dimensions with strong cooling performance thanks to its five heatpipes and an optimized NF-A9 fan featuring Flow Acceleration Channels and an AAO frame. Its 95×95 mm footprint and 125 mm height provide full compatibility with tall memory modules and PCIe slots on most Intel and AMD motherboards, including µATX and mini‑ITX. PWM support and a Low-Noise Adaptor enable quiet, automatic speed control, and the SecuFirm2™ mounting system ensures secure, long-lasting contact across multiple sockets.

Suitable for

• Compact desktops and small form-factor builds (micro‑ATX, mini‑ITX)
• Systems with tall RAM heatspreaders where clearance is required
• Setups that require PCIe slot access next to the CPU socket
• Quiet workstations and home PCs needing efficient, low-noise cooling

How to use

Install the SecuFirm2™ mounting brackets appropriate for your CPU socket and apply a small, even amount of NT-H1 thermal compound to the CPU heatspreader. Mount the NH-U9S on the socket and fasten according to the included instructions to ensure even contact pressure. Connect the NF-A9 fan to the CPU fan header to enable PWM control; if desired, attach the optional second NF-A9 fan using the supplied mounting clips and a Y-cable to operate both from a single header.

Recommendations

For best results in compact cases, ensure adequate case airflow (intake and exhaust) and consider using the Low-Noise Adaptor if lower acoustic levels are preferred. Use the AM5 offset mounting bars when installing on AM5 to optimize contact with CCD areas for slightly lower CPU temperatures.
