Blæser Inter-Tech RS-041 RGB 12 cm sort

The Inter-Tech RS-041 RGB 12 cm fan is a 120 mm computer cooling fan with integrated RGB lighting. It combines fluid bearing technology for quiet, long-lasting operation with 16 RGB LEDs arranged in two transparent rings to create a uniform lighting effect. Rubberized pads on both sides of the frame reduce vibration and allow installation as either an intake or exhaust fan. The fan connects to the motherboard with a 4‑pin PWM connector for speed control and a 3‑pin 5V RGB header for synchronized lighting with other compatible components.

Advantages

Fluid bearing technology ensures reduced noise and extended service life while the dual-ring arrangement of 16 RGB LEDs provides even, customizable lighting. Corner rubber pads minimize vibration transfer to the case, and the dual connection—4‑pin PWM for fan speed and 3‑pin 5V RGB for lighting—allows independent control of cooling and illumination through compatible motherboards.

Suitable for

• Standard ATX, micro‑ATX and mini‑ITX PC cases supporting 120 mm fans
• Systems where quiet, long‑lasting cooling is required
• Builds that require synchronized 5V RGB lighting with the motherboard
• Use as intake or exhaust fan to improve case airflow

Key specifications

How to use

Mount the fan in a 120 mm slot in your PC case using the provided screws, observing airflow direction indicated on the fan frame. Connect the 4‑pin PWM cable to a motherboard fan header for automatic speed regulation based on system temperature, and attach the 3‑pin 5V RGB cable to a compatible 5V RGB header to enable synchronized lighting. Ensure connectors are aligned and the system is powered off during installation.

Recommendations

Install the fan where it contributes to a balanced airflow—intake at the front or bottom and exhaust at the rear or top—and configure motherboard PWM profiles for a balance between cooling performance and noise. Use compatible 5V RGB headers and software to achieve synchronized lighting effects.
