SXDOOL 12 V 9.81 W 4-wire case fan

This SXDOOL fan is a 12 V DC case fan rated at 9.81 W with a 4-wire PWM connector. It fits server and laptop cooling roles where a compact, powered fan is required. Builders needing a different voltage or a 3-pin connector should look elsewhere.

Thermals noise and power draw

At 9.81 W the fan draws modest power from a 12 V rail while delivering airflow for server or laptop chassis. The 4-wire interface allows speed control to balance cooling and acoustic output. No further thermal or acoustic specifications are provided.

Questions about this item

How do I connect the 4-wire connector to a 12V motherboard header?

Align the keyed 4-wire plug with the 12V fan header and press straight down; the common mistake is forcing it offset by one pin, which leaves the tachometer wire unconnected.

When should I replace the EFB0151S1-C010-S99 fan?

Replace it when bearing noise appears, airflow drops noticeably, or the 9.81W motor no longer spins at full speed on a 12V supply.
