Small square 40mm black case fan with transparent blades and two-pin connector

SXDOOL

SXDOOL 4010 40mm 12V 1.8W 8500rpm 2-pin case fan

SKU CH-E91D-4YKZM

A 40 mm maglev case fan moving 9.5 CFM at 8,500 rpm with a 2-pin connector and 32 dBA noise

  • Fan size40 mm
  • Power input connector2 Pin
  • Maglev bearing cuts friction for longer life
  • 8500 rpm delivers 9.5 cfm airflow for tight spaces
  • 32 dBA keeps noise low at full speed
  • 5–13.8 V range fits varied 12 V headers
  • 40×40×10 mm frame drops into standard 4010 mounts

Compact 40 mm maglev case fan

The SXDOOL 4010 measures 40 by 40 by 10 millimetres and uses a maglev motor with a two-pin power connector. It suits small-form-factor builds, server trays or tight GPU brackets where a standard 120 mm frame cannot fit. Buyers who need higher static pressure for dense radiators or larger airflow for full-tower cases should look elsewhere.

Thermals and power in daily use

Rated at 12 volts with a 4.5 to 13.8 volt operating range, the fan draws 0.15 amps for 1.8 watts and spins at 8500 rpm. It delivers 9.5 cfm of air volume while producing 32 dBA of noise. The wide voltage window lets it run from motherboard headers or fan controllers without exceeding its power envelope.

Build quality and mounting implications

The frame is glass-fibre reinforced plastic with a PBT shell and PA blades, meeting environmental protection certification. Maglev bearing construction removes physical contact at speed, reducing wear and keeping vibration low over time. Two-pin wiring provides power and ground only, so speed reporting or PWM control is not available.

Questions about this item

How do I install the 4010 fan and which step is often missed?

Mount the 40x40x10 mm frame with four screws, then connect the 2-pin plug to a 12 V header; the step often missed is checking that the motherboard header supplies 4.5–13.8 V so the maglev motor starts reliably.

What maintenance or replacement will the maglev motor need later?

The maglev motor has no physical contact bearings to wear out, so no routine lubrication or bearing swap is required; only clean dust from the PA blades periodically to keep the 9.5 cfm airflow at 8500 rpm.

What limit appears first during sustained 8500 rpm operation?

The 1.8 W power draw at 0.15 A is the first constraint; if the 2-pin header or wiring cannot deliver steady current the fan will throttle before heat or noise (32 dBA) becomes an issue.
