## Long description

Gelid FN-SX05-40 is a compact 50×50×15 mm computer case fan designed for spot cooling in small form-factor systems. Operating at 12 V and capable of up to 4000 RPM, this 5 cm fan delivers targeted airflow and static pressure while maintaining low audible output. Its small footprint makes it suitable for cases, heatsinks, and confined spaces where larger fans cannot be installed.
Advantages
The fan features optimized blade geometry that balances airflow and static pressure for effective cooling of radiators, heatsinks and tight vents. With a rated noise level of 23 dB at high speed and a predicted long service life (MTTF of approximately 50,000 hours at 40°C), it supports continuous operation with minimal acoustic impact. Compact dimensions and a choice of black or white finish simplify integration into various builds.
Suitable for
Small form-factor PC cases and mini-ITX builds
Spot cooling for VRMs, chipsets and M.2 slots
Heatsinks and compact radiators with restricted fan clearance
Embedded systems, NAS units and industrial enclosures with limited space

Maximum speed: 4000 RPM
Maximum airflow: 12.9 CFM
Maximum static pressure: 2.8 mmH2O
Noise level (high speed): 23 dB
Available colours: Black or White
Expected reliability: ~50,000 hours MTTF at 40°C
How to use
Install the fan in the intended location using the appropriate mounting holes or brackets for 50 mm fans. Connect to a 12 V fan header on the motherboard or a compatible power source, observing correct polarity. Ensure clear intake and exhaust paths by avoiding obstructing cables or other components. If precise speed control is required, use a compatible fan controller or a motherboard header that supports voltage or PWM-based control methods when available.
Usage recommendations
For optimal cooling and low noise, position the fan to provide direct airflow to the hot component and maintain a short, unobstructed airflow path. Regularly inspect and clean the blades and surrounding area to prevent dust buildup that can reduce airflow and increase noise. When used in systems sensitive to vibration, add rubber grommets or anti-vibration mounts to minimize transmitted noise.
