Compact 80mm PWM fan for tight builds

The Corn Electronics 80mm case fan fits small-form-factor cases and confined GPU zones where larger fans cannot mount. Its 4-pin PWM header allows the motherboard to regulate speed automatically based on thermal load. The black, non-LED frame keeps the appearance neutral for any build theme.

12V PWM control range and current draw

The fan operates on a standard 12V rail and draws 0.5A at typical speed, rising to 1.3A when the PWM duty cycle demands maximum airflow. Four-pin control lets the board spin the motor down to near-zero RPM at idle and ramp up only when temperatures climb. No external controller or voltage adapter is required.

Double ball bearing rated to 7000rpm

Double ball bearings support continuous operation at up to 7000rpm, delivering sustained static pressure for restrictive heatsinks or dense mesh panels. At that ceiling the fan moves significant air through 80mm by 38mm frames, but acoustic output rises sharply and bearing life shortens compared to lower-speed running. Builds needing silent idle or higher peak CFM will need a larger-diameter alternative.

Questions about this item

What does the 4Pin PWM connector let the motherboard control on this fan?

The 4Pin PWM connector lets the motherboard vary the fan speed automatically based on system temperature, so the fan only spins as fast as needed.

What does the 10000rpm figure mean when the fan is installed in a case?

The 10000rpm label is the model designation; the manufacturer highlights list a maximum of 7000rpm, so actual speed will not exceed that value.

How does the 4Pin PWM interface affect the maximum speed the fan can reach?

The 4Pin PWM interface allows the motherboard to command speeds up to the highlighted 7000rpm maximum, but the fan will not exceed that limit regardless of the PWM signal.
