SILVERSTONE 40mm ventilátor SST-FTF4010B PWM — 40 mm PWM chladiaci ventilátor

The SILVERSTONE 40mm Fan SST-FTF4010B PWM is a compact 40 mm cooling fan designed for targeted airflow in small form factor PC cases, external enclosures and electronics with limited mounting space. With a 4-pin PWM connector it supports automatic speed regulation according to system load, allowing quieter operation at low demand and increased airflow when temperatures rise. The fan's small footprint and standard mounting pattern make it suitable for confined areas where a reliable cooling solution is required.

Advantages

The fan offers PWM speed control for dynamic performance and noise balance, a compact 40 mm diameter for tight installations, and compatibility with standard 4-pin PWM headers on motherboards and controllers. Its construction focuses on stable airflow in constrained spaces and straightforward installation using common screw positions. The design aims for consistent rotation and cooling efficiency within its size class.

Suitable for

• Small form factor PC cases and mini-ITX builds
• External hard drive enclosures and NAS units with limited space
• Embedded systems, routers and industrial electronics requiring spot cooling
• Graphics card or VRM cooling in custom rigs where space is restricted

Key specifications

• Fan diameter: 40 mm
• Connector: 4-pin PWM header for speed control
• Form factor: compact, low-profile design for confined installations
• Mounting: standard screw holes for 40 mm fans
• Intended use: airflow for electronics and PC components in tight spaces

How to use

Connect the fan to a compatible 4-pin PWM header on the motherboard or a PWM-capable fan controller to allow automatic speed regulation. Mount the fan using the appropriate screws in the available 40 mm mounting points or secure it with suitable brackets or foam pads if standard holes are not accessible. Ensure airflow direction matches the cooling requirement (intake or exhaust) and avoid obstructing the intake or outlet. Verify fan operation in BIOS or monitoring software and confirm PWM control is enabled for dynamic speed adjustment.

Recommendations

For quiet operation, enable firmware or software PWM control and allow the fan to run at lower PWM duty cycles under light loads. When installing in enclosures, maintain minimal clearance around the fan to prevent airflow restriction and periodically inspect for dust accumulation to preserve performance.
