  • New condition ensures full rated performance from first use

90 mm 4-wire case fan

This 90 mm case fan runs on 12 V and draws 0.90 A through a 4-wire PWM connection. It fits standard 92 mm mounting points and provides speed control for balanced airflow and noise levels. The unit is supplied new and ready for installation in compatible chassis.

Replaces 3-wire 90 mm fans

Upgrading from a 3-wire model adds PWM control so the fan can scale speed with system load instead of running at a fixed rate. The change is worthwhile when the motherboard or fan controller offers a 4-pin header and variable-speed operation is needed. Builders who require larger diameter fans or higher static pressure should look elsewhere.

Questions about this item

What are the mounting hole dimensions for the DS09238T12HP004 90mm fan?

The DS09238T12HP004 uses a standard 90mm frame with mounting holes spaced for 90mm fan positions in typical PC cases.

How do I correctly connect the 4-wire PWM connector on this 12V 0.90A fan?

Align the 4-pin connector key with the motherboard header notch; the fourth wire carries the PWM signal for speed control, so forcing it backwards disables fan regulation.
