High-Speed 120 mm Case Fan

The SXDOOL DF1203812B2FN is a 120 mm by 38 mm case fan built for high-static-pressure airflow. It spins between 6000 and 6499 RPM using a dual-ball bearing and draws 4.50 A from a standard 4-pin PWM header. The black, non-LED frame suits industrial or mining rigs that need maximum air movement through dense heatsinks or restricted chassis.

Suited For High-Resistance Cooling

This fan targets builders who must push air through thick radiators, tightly stacked drives or custom mining enclosures. The high current draw and speed range make it effective where standard 120 mm fans stall. Buyers who need quiet operation, low power consumption or RGB lighting should look elsewhere, as the dual-ball bearing and 4.50 A rating prioritise raw airflow over acoustics or aesthetics.

4.50 A Current Draw Decides Fit

The single specification that determines compatibility is the 4.50 A rating on the 4-pin connector. Most consumer motherboard headers are rated for 1 A to 2 A, so this fan will trip protection or damage the header if plugged directly into a typical board. It requires a dedicated high-current fan controller, a powered hub or a server-class header rated for at least 5 A continuous output.

商品問答

How loud and hot does the DF1203812B2FN run at 6000-6499 RPM all day?

At 6000-6499 RPM this 120 mm fan moves a lot of air, so expect noticeable noise and a 4.50 A draw on the 12 V rail; ensure your case airflow can exhaust the heat it pushes.

What connector and voltage does the 4-pin DF1203812B2FN need to start spinning?

It requires a standard 4-pin PWM header supplying 12 V DC; the motherboard or fan controller must be able to deliver 4.50 A for full speed.

Will the 38 mm thick DF1203812B2FN fit in the same 120 mm holes as my older 2-ball bearing fans?

The mounting holes match the 120 mm pattern, but the 38 mm depth is thicker than many older fans, so check chassis and radiator clearance first.
