Delta 40mm 3.3V DC Fan

The Delta AFB0405HHA is a 40 mm square frame fan built for tight spaces inside servers, network appliances or compact workstations. It runs on 3.3 V DC and draws 0.16 A, making it suitable for low-voltage headers on industrial boards or embedded systems. The black frame and blade assembly contain no lighting.

Dual ball-bearing 3-wire design

Double ball bearings provide longer service life and consistent rotation compared to sleeve alternatives. The three-wire lead delivers power, ground and a tachometer signal so the host can monitor speed in real time. No PWM wire is present, so speed control depends on voltage regulation.

Simple two-screw mounting

Standard 40 mm hole spacing fits most legacy CPU coolers and chassis brackets without adapters. The short 10 mm depth clears low-profile heatsinks but verify clearance against nearby capacitors or VRM heatsinks. Incorrect polarity on the 3.3 V line will prevent spin-up and may damage the motor.

Perguntas sobre este artigo

How much current does the 3.3 V motor draw once installed?

The motor draws 0.16 A at 3.3 V DC, so a standard 3.3 V rail can supply it without extra headroom.

What does the three-wire lead provide compared with a two-wire version?

The third wire carries a tachometer signal so the motherboard can monitor fan speed in real time.

Will the 40 mm square frame and 10 mm thickness fit my existing mounting holes?

The frame measures 40 mm by 40 mm and is 10 mm thick, matching the standard 40 mm fan mounting pattern.
