Small square 12V PWM cooling fan with four wires

Fans

Fans 12V 3010 3CM PWM 4 lines Cooling Fan

SKU CH-7AC5-23P0G

12 V PWM case fan with four-wire speed control for 30 mm mounts

  • 12V PWM control for precise speed regulation
  • 4-wire connection enables automatic fan management
  • 3010 form factor fits compact chassis spaces
  • New condition ensures reliable cooling performance

Compact PWM Cooling Fan

The 3010 form-factor fan runs on 12 V power and uses a four-wire PWM interface for precise speed control. It is a direct replacement for the SUNON MC30101V1-D01U-S99 unit in space-constrained chassis or industrial enclosures. Buyers who need a larger frame size or higher airflow rating should look elsewhere.

Sustained Load Behaviour

PWM control lets the fan ramp speed to match continuous thermal demand rather than running at a fixed maximum. The four-line connection feeds real-time tachometer data back to the controller for stable closed-loop operation. Systems that lack a PWM header or require 5 V operation will not be compatible.

Questions about this item

How much noise and heat does the SUNON MC30101V1-D01U-S99 12V 3010 3CM PWM fan produce when running continuously?

The 12V PWM fan uses a 4-wire interface for automatic speed control, which reduces noise and heat output at lower loads compared to fixed-speed models.

What motherboard header is required to connect the 4-wire PWM fan?

A standard 4-pin PWM fan header on the motherboard is needed to power the fan and enable speed control via the fourth wire.
