4010 5V Double Ball Bearing Fan

The AD0405HB-G72 is a 40 mm by 10 mm case fan designed for compact enclosures that run on a 5 V supply. Its double ball bearing construction targets builders who need longer service life than sleeve alternatives can provide. The 0.25 A draw keeps power demand low for small-form-factor or embedded systems. It suits anyone replacing a noisy original cooler in tight chassis.

Practical Limits of the 5 V Interface

A 5 V header caps the available current, so the fan cannot reach the airflow of higher-voltage models. The 4010 frame restricts static pressure, making it unsuitable for dense radiators or filters. Buyers who need more cooling capacity or PWM speed control should look elsewhere. The fixed voltage also means speed cannot be modulated by the motherboard.

Questions about this item

Which variant of the AD0405HB-G72 should I pick for a 5 V header?

The AD0405HB-G72 is a single 5 V model drawing 0.25 A, so there is no alternative version to choose from.

What does the 0.25 A rating mean once the fan is installed?

It shows the current the fan pulls from a 5 V header; the double ball bearing keeps noise low during continuous operation.
