Compact 40 mm Case Fan
The SXDOOL 40 mm axial fan fits tight chassis bays and connects via a standard three‑pin motherboard header. It runs on 12 V power, drawing 6.8 W at a rated speed of 8500 RPM. The dual‑ball bearing design supports continuous operation in industrial or custom small‑form‑factor builds.
Suited For & Not Suited For
This fan serves builders who need targeted airflow in a 40 mm mounting footprint and accept a fixed three‑pin connection. It is not suited for installations that require a four‑pin PWM header for automatic speed curves or for cases that only provide larger fan apertures. The non‑LED black finish keeps the appearance neutral.
Deciding Specification
The 40 mm frame size combined with a three‑pin 12 V interface determines fit; verify that your chassis has a matching 40 mm cut‑out and that the motherboard or fan controller supplies a three‑pin header before ordering.

Questions about this item
Does my motherboard need a three-pin header to run this 12 V 6.8 W fan?
Yes, it uses a standard three-pin connector and draws 0.57 A at 12 V, so a matching motherboard header is required.
Will the 40 mm frame and 28 mm depth fit in the same mounting holes as my older 40 mm fans?
The fan measures 40×40×28 mm, matching the common 40 mm mounting pattern used by many legacy coolers and chassis.
How can I confirm the fan is spinning at the rated 8500 RPM after installation?
Check the RPM reading in BIOS or a monitoring utility; it should report around 8500 RPM when the header supplies full 12 V.
