Small square black 4010 case fan 40 by 40 by 10 mm

SXDOOL

SXDOOL 4010 5V 40x40x10mm 43mm case fan

SKU CH-WCN1-NFET0

A 40 mm square, 10 mm thick case fan running at 5 V with a 43 mm impeller and 31 mm hole spacing

  • 5 V operation suits low-voltage builds
  • 40 x 40 x 10 mm frame fits tight spaces
  • 43 mm impeller diameter moves air in compact chassis
  • 44 mm diagonal mounting holes match standard 40 mm fan patterns
  • 31 mm adjacent hole spacing allows secure four-screw installation

Compact 5 V 4010 fan for tight builds

This 40 mm square frame measures 10 mm thick and carries a 43 mm diameter impeller. It runs on a 5 V supply, making it suitable for graphics-card coolers, small-form-factor cases or custom loops where space is limited. Mounting holes sit on a 44 mm diagonal with 31 mm spacing between adjacent holes.

Thermals, noise and power in daily use

The 5 V input keeps current draw low for a fan of this footprint. No RPM, airflow or decibel figures are provided, so exact thermal capacity and acoustic profile cannot be stated. Expect modest cooling suited to low-heat components rather than high-TDP loads.

Mounting hardware and software impact

No screws, adapters or control software are mentioned in the data. The fixed hole pattern determines compatibility; builders must verify the 44 mm diagonal and 31 mm pitch match their device. Without bundled accessories, installation relies on existing fasteners or separately sourced hardware.

Questions about this item

How do I mount the 4010 fan using the 44 mm diagonal hole spacing?

Align the fan with the 44 mm diagonal mounting holes on your graphics card or heatsink, insert screws through the 31 mm adjacent holes, and tighten evenly; the step most people miss is checking the 31 mm centre-to-centre distance before drilling or tapping.

What maintenance will the 4010 fan need over time?

Clean dust from the blades and intake every few months with compressed air; the sleeve bearing is not user-serviceable, so plan to replace the entire 40 mm unit when noise or vibration increases.

What is the first limit reached during continuous 5 V operation?

The sleeve bearing’s thermal tolerance is the first limit; sustained load raises internal temperature until lubricant degrades, causing rising noise and reduced airflow before the motor itself fails.
