Ruth's sister

Ruth's sister 3000RPM PWM internal power cable

SKU CH-QQH1-B9TK3

Thin 4-pin PWM chassis fan runs up to 3000 RPM with temperature-based speed control

  • 4-pin PWM connector enables precise speed control
  • 3000 RPM maximum delivers strong airflow for cooling
  • Temperature-based adjustment balances noise and performance
  • Slim chassis design fits tight case spaces

Thin 4-pin PWM fan for chassis cooling

This 4-pin PWM fan fits standard case mounts and spins up to 3000 RPM under thermal control. The thin profile suits compact builds where clearance is tight. Adjustable speed lets the curve match component temperatures automatically.

Practical limits of 4-pin PWM control

PWM duty cycle governs the 3000 RPM ceiling, so the motherboard or controller must supply a clean signal for full range. Minimum speed is set by the fan's own motor characteristics, not the header. Builders needing variable-speed operation on 3-pin voltage headers will not get PWM regulation.

Highlights

  • 4-pin PWM connector enables precise speed control
  • 3000 RPM maximum delivers strong airflow for cooling
  • Temperature-based adjustment balances noise and performance
  • Slim chassis design fits tight case spaces

Questions about this item

Should I choose the 3000RPM version or a lower speed model for my case?

The 3000RPM PWM fan delivers maximum airflow when the system demands it, while the temperature control automatically reduces speed during lighter loads for quieter operation.

What does the 3000RPM figure mean once the fan is installed in my PC?

It represents the peak rotational speed under full PWM duty cycle; actual speed varies in real time based on the temperature sensor input from your motherboard header.
