Chassifläkt LogiLink FAN103

The LogiLink FAN103 PC case cooler is a 120×120×25 mm DC brushless fan designed to improve airflow and help maintain stable internal temperatures in desktop computers. It uses sleeve bearings, operates at a rated voltage of DC 12V (operation range DC 9–13V) and draws approximately 0.23 A. The fan delivers up to 75 CFM airflow at a rotation speed of about 2000 RPM and has an expected service life of 30,000–50,000 hours. Its lead wire is a 4‑pin 1007#26# cable, 280 mm long, and the unit weighs 160 g.

Advantages

The FAN103 offers a standard 120 mm form factor compatible with most PC cases, a brushless DC motor for efficient operation, and sleeve bearings for simple, cost-effective reliability. With a maximum airflow of 75 CFM and a moderate noise level of 31.3 dB(A), it balances cooling performance and acoustic comfort. The 4‑pin connector and 280 mm cable provide convenient reach for common motherboard and fan header layouts.

Suitable for

• General desktop PC cooling (case intake or exhaust)
• Office and home computers where quiet, reliable airflow is needed
• Systems with standard 120 mm fan mounts

How to use

Install the fan in a 120 mm mounting position in the PC case, aligning airflow direction according to your cooling layout (intake or exhaust). Secure the fan with appropriate screws and connect the 4‑pin cable to a compatible motherboard fan header or controller. Power the system within the specified voltage range (DC 9–13 V). If PWM speed control is not available, the fan will run at its nominal speed when supplied with rated voltage.

Recommendations

For best results, place the fan to support a clear airflow path through the case, keep dust filters clean, and ensure adequate clearance from cables and components. If quieter operation is required, use a fan controller or motherboard PWM header (if supported) to reduce speed; for maximum cooling, ensure unobstructed intake and exhaust routes.
