80 mm double-ball PWM fan

The SXDOOL 80 mm case fan uses a double ball bearing rated for 50000 hours at 25 C and 45 to 85 percent humidity. It draws 3.84 A at 12 V through a standard four-pin PWM connector. The 38 mm thick frame suits servers or workstations that need high-volume airflow in a compact slot. Buyers who need larger diameter fans or RGB lighting should look elsewhere.

Four-pin PWM current limits

The fan requires a motherboard header capable of supplying 3.84 A at 12 V, which exceeds many consumer four-pin headers rated around 1 A. If the header cannot deliver that current the fan may run at reduced speed or fail to start. A three-pin header will power the fan but removes PWM control so speed cannot be regulated by the board. Builders without a high-current header must use a dedicated fan controller or powered hub.

38 mm depth and screw alignment

The 38 mm thickness is deeper than standard 25 mm case fans so verify clearance against side panels, cable routing and CPU cooler overhang before mounting. Four corner holes accept standard M3 screws; overtightening can crack the plastic frame. Because the bearing is not user-serviceable, any grinding noise after installation usually means the fan must be replaced rather than lubricated.

Questions about this item

Which 80 mm version should I choose for a 12 V PWM header?

The fan is an 80 x 80 x 38 mm unit with a 4-pin PWM connector, rated at 12 V and 3.84 A, so it fits any standard 4-pin motherboard header.

What does the 3.84 A current rating mean once the fan is installed?

At full PWM duty the fan draws 3.84 A from the 12 V rail, delivering the maximum airflow and pressure the double-ball bearing motor can produce.

What does the 4-pin PWM interface cap in practice?

The 4-pin PWM interface allows the motherboard to vary speed from minimum to maximum while reporting real-time RPM through the tachometer wire.
