Ultra-violent dual-rotor server fan
The SXDOOL IFD04048B12-A01 packs two counter-rotating rotors into a single 40 by 40 by 48 millimetre frame. It is built for 1U server chassis and other tight spaces that demand concentrated airflow from a minimal footprint. The unit draws a maximum of 1.9 amperes at 12 volts, with a measured operating current of 0.8 amperes. PWM control allows the motherboard or fan controller to regulate speed precisely.
Thermals noise and power in normal use
Dual rotors move a high volume of air through the rectangular housing while the PWM circuit keeps RPM proportional to thermal load. At the measured 0.8 ampere draw the fan runs cooler and quieter than its peak rating suggests. The 12 volt supply rail feeds both rotors in parallel through the integrated wiring. Acoustic output scales with the PWM duty cycle, staying restrained at low loads.
Industrial plastic body and short six-pin lead
The moulded industrial plastic frame weighs 89 grams and resists vibration in dense rack mounts. A 3.5 centimetre six-pin plug terminates the parallel-wired leads, so the installer must route the cable immediately adjacent to the fan header. Red and black conductors carry positive and negative respectively. The compact connector suits server backplanes but may require an extension for standard desktop boards.

Questions about this item
How do I install the IFD04048B12-A01 fan in a 1U server and what wiring step is often missed?
Mount the 40×40×48 mm frame with four screws, then connect the 6-pin small plug; the two rotors are already wired in parallel so only one PWM header is needed.
What maintenance will the dual-rotor fan need over time?
The industrial plastic body and dual-rotor assembly run on sealed bearings; periodic dust removal from the blades is the only upkeep required.
At what point does the 12 V 1.9 A PWM fan hit its thermal or current limit during sustained load?
Measured current settles at 0.8 A under normal operation, well below the 1.9 A maximum, so the PWM controller reaches its duty-cycle ceiling before the motor hits its current limit.
