  • Accessory TypeCooler
  • DC5V .4A blower fan cools notebook efficiently

Replacement Blower Fan for Notebooks

This 4-wire blower fan operates at DC5V 0.4A and matches the SUNON EG75070S1-C260-S9A part number. It is intended for owners who need to replace a failed or noisy original cooler in a compatible notebook. Each unit is tested before shipping to confirm function.

Four-Wire PWM Control Limitation

The 4-wire interface supports pulse-width modulation speed control and tachometer feedback, but the fan only responds to signals the host notebook provides. If the system firmware does not drive the PWM line, the cooler may run at a fixed speed or not spin at all. No external controller is included.

Direct Swap for Identical Part Numbers

This fan replaces the exact SUNON EG75070S1-C260-S9A blower when the original has worn bearings or reduced airflow. The upgrade is worth it only when the installed cooler shares the same 260 model code and 4-wire pinout; different pin arrangements or voltage ratings will not work.

Questions about this item

Which SUNON blower fan matches my laptop if the original part number is EG75070S1-C260-S9A?

This unit carries the exact EG75070S1-C260-S9A code and a 4-wire PWM connector, so it fits any notebook that originally shipped with that part number.

What does the 0.4 A rating mean for daily cooling performance?

At 0.4 A on a 5 V rail the fan draws 2 W, giving a blower-style airflow that targets the heatsink directly rather than circulating air around the chassis.

How does the 4-wire PWM interface control the fan in practice?

The fourth wire carries a PWM signal from the motherboard, allowing speed to scale from idle to full RPM without voltage changes, so the EC can tune noise and thermals in real time.
