## Summary description

Noctua NF19011 HEDGEHOGS is a compact 20x20x36 mm cooling fan designed for CPU coolers, heatsinks and confined spaces. It uses a 3-pin power connector for PWM-compatible motherboards, delivering reliable airflow and quiet operation in tight installations. Suitable for system cooling, small-form-factor builds and targeted hotspot cooling.

## Long description

Noctua NF19011 HEDGEHOGS is a compact 20x20x36 mm cooling fan intended for CPU coolers, heatsinks and other confined spaces where targeted airflow is required. The fan uses a three-pin power connector and is designed to provide reliable airflow and low noise levels in small-form-factor systems and tight installations. Its small size makes it suitable for hotspot cooling and components with limited clearance.
Advantages
The compact dimensions allow installation in cramped spaces where standard fans do not fit, while the axial design provides focused airflow for efficient heat dissipation. The three-pin connector ensures broad compatibility with standard motherboard headers and simple control via voltage-based fan regulation. The fan is engineered for quiet operation, making it suitable for systems that require low acoustic output without sacrificing cooling performance in localized areas.
Suitable for
 Small-form-factor PC builds and mini-ITX systems
 CPU coolers and heatsinks with limited clearance
 Targeted hotspot cooling for VRMs, chipsets and storage devices
 Industrial or embedded equipment with constrained installation space
When it may not be suitable
This fan is not intended as a replacement for full-size case fans where high overall airflow is required; its small frame delivers focused but limited cubic feet per minute compared to larger fans. It may also be unsuitable when PWM-based speed control from a four-pin header is required, since the device uses a three-pin connector and voltage-based speed regulation.
Key specifications
 Dimensions: 20 x 20 x 36 mm
 Connector type: 3-pin analogue fan connector
 Mounting orientation: axial, designed for tight clearance installations
 Application focus: localized / targeted cooling for small components
 Acoustic characteristic: designed for low-noise operation in small form factors
How to use
Install the fan in the available mounting location on the cooler, heatsink or chassis, ensuring correct airflow direction toward the component that requires cooling. Connect the three-pin plug to a compatible motherboard fan header or a voltage-controlled fan hub. Verify secure mounting and cable routing to prevent vibration contact with neighbouring components. Adjust fan speed via motherboard BIOS or fan controller that supports three-pin voltage regulation to balance cooling performance and noise.
What to consider before purchase
 Confirm available clearance and mounting points for a 20x20x36 mm fan
 Ensure your motherboard or controller supports a three-pin analogue fan connection
 Assess whether a small, focused airflow solution meets the cooling needs of your component
 Check compatibility with your cooler or heatsink bracket and any required mounting hardware
Usage recommendations
Use this fan for targeted cooling zones rather than general case ventilation. For optimal results, pair it with appropriate airflow paths and ensure intake and exhaust balance within the enclosure. When replacing an existing fan, match the airflow direction and verify electrical compatibility before powering on.
