SKU CH-MWMA-JAXA8

80 mm PWM case fan with 4-wire speed control and 12 V, 0.65 A rating

  • PWM control enables precise speed regulation
  • 12V 0.65A power draw suits standard headers
  • 4-wire design supports motherboard monitoring
  • NMB 8025 build for reliable cooling performance

Compact 4-wire PWM case fan

The Fans 3110RL-04W-B86 is a 12 V, 0.65 A case fan designed for system builders who need a standard 4-pin PWM connection for motherboard-controlled speed regulation. Its thermostat function allows automatic adjustment based on internal temperatures, making it suitable for general chassis airflow tasks.

0.65 A current draw with thermostat control

At 0.65 A the fan draws modest power from a 12 V header, providing enough headroom for typical case ventilation without overloading standard fan connectors. It runs out of capacity in high-static-pressure scenarios such as dense radiator stacks or restrictive dust filters where higher airflow or pressure ratings would be required.

Questions about this item

Will the 4 wire PWM connector on this 3110RL-04W-B86 fan work with a motherboard that only has 3 pin headers?

Yes, the 4 wire PWM plug fits a 3 pin header; the fan will run at full 12 V speed without speed control.

How can I confirm the 3110RL-04W-B86 is spinning at the correct speed after installation?

Check the fan RPM in BIOS or monitoring software; the PWM signal should vary the speed according to temperature.
