## Summary description

AIREN RPM Clever 3-pin to PWM function with RPM control is a computer cooling fan designed to integrate 3-pin power connectors with PWM-like speed management and real-time RPM monitoring. It allows adjustment of fan speed and provides RPM feedback for system control. Suitable for PC cases, CPU coolers and custom cooling setups where controlled airflow and RPM reporting are required.

## Long description

AIREN RPM Clever converts a 3‑pin fan connector to a 4‑pin PWM‑style connection and enables manual or automatic control of fan rotational speed with RPM feedback. The device includes a temperature sensor that can stop the fan when the measured temperature falls below 20°C, reducing unnecessary noise. It is compact and lightweight, intended for use with PC case fans, CPU coolers and custom cooling configurations where controlled airflow and RPM reporting are required.
Advantages
The adapter provides both manual and automatic speed adjustment, offers RPM monitoring for system control, and supports automatic fan stop below 20°C to reduce noise. It is small (57 × 22 × 20 mm), lightweight (10 g) and easy to install, converting a 3‑pin connector to a 4‑pin PWM interface on the motherboard without additional components.
Suitable for
PC case fans
CPU coolers with 3‑pin fans
Custom cooling setups requiring RPM feedback
Systems where noise reduction at low temperatures is desired

How to use
Connect the 3‑pin fan connector to the device and plug the 4‑pin connector into the motherboard PWM header. Select manual or automatic mode according to your cooling needs. The built‑in temperature sensor will automatically stop the fan if the measured temperature drops below 20°C. Ensure the connected fan does not exceed the specified optimal load (12 W).
Usage recommendations
For reliable operation, use with fans within the specified voltage and load range and place the temperature sensor where it can accurately reflect the area you want to control. Avoid exceeding the 12 W load and verify proper seating of connectors during installation.
