9cm 4-Wire Dual Ball Bearing Fan

The LORDWORLD AFB0912SH is a 12V cooling fan designed for systems requiring a 9cm form factor with PWM control. It suits builders replacing a Delta 9025 or 9225 unit where a 4-wire interface and dual ball bearing construction are specified. The 1A current draw supports standard 12V rail connections in compatible chassis or hardware.

5400RPM Speed and Airflow Headroom

At 5400RPM the fan delivers high airflow for dense component layouts or restricted venting, moving enough air for typical 9cm mount points under load. Headroom exists for PWM speed reduction when thermal demand drops, lowering acoustic output. It runs out in scenarios needing larger diameter blades, higher static pressure than a 9cm frame provides, or voltage rails other than 12V.

Questions about this item

Will the AFB0912SH 4-wire PWM connector work with my older motherboard that only has 3-pin fan headers?

The 4-pin connector fits a 3-pin header; the fan will run at full 12 V speed but PWM control will not be available.

How can I confirm the AFB0912SH is spinning at its rated 5400 RPM after installation?

Check the RPM value reported in BIOS or fan-control software while the fan is powered; it should read 5400 RPM at full speed.
