Noctua NH-L9x65 chromax.black Low-Profile CPU Cooler with 4 Heatpipes — Black Coated Heatsink, NF-A9x14 HS-PWM Fan, SecuFirm2 Mounting for Intel & AMD, 65mm Height, Ultra-Quiet

General Information

• Type: Premium low-profile air CPU cooler
• Designed For: Small form factor (SFF) builds, HTPCs, and compact systems
• Use Case: Offers strong cooling performance in tight spaces while maintaining full compatibility with tall RAM and PCIe components
• Color: All-black edition – ideal for stealthy or themed PC builds
• Warranty: 6 years – standard for Noctua coolers

Heatsink & Cooling Performance

• Total Height: 65 mm (including fan) – compact enough for most SFF cases
• Footprint: 95 x 95 mm – ensures full clearance for RAM and PCIe slots
• Heatpipes: 4 x 6mm nickel-plated copper heatpipes – efficient heat transfer
• Base Material: Nickel-plated copper base with black aluminum fins
• Thermal Performance: Significantly better than ultra-low-profile coolers like the NH-L9i
• Design: Optimized for use in ITX chassis and other space-limited environments

Included Fan: NF-A9x14 HS-PWM chromax.black
