40mm 12V case fan for compact builds

This 4020 form-factor fan fits tight chassis where a 40 mm frame is the only option. It runs on a standard 12 V DC supply and uses a simple two-wire connection for direct motherboard or controller attachment. The low 0.6 W power draw keeps load on small power budgets minimal. It suits embedded systems, slim HTPC cases or GPU shroud replacements.

Ultra-quiet operation at 0.6 W

The HA40201V4-0000-999 model is rated for ultra-quiet running so it adds little audible noise in normal use. At just 0.6 W the thermal contribution to the system is negligible while still moving air through restricted spaces. Two-wire power means speed is voltage-dependent rather than PWM-controlled. Buyers who need variable speed headers or higher static pressure should consider other models.

Questions about this item

How do I connect the 2-wire 12V 0.6W fan to my motherboard or controller?

Plug the two leads into a 12 V DC header or solder them to a 12 V rail, observing polarity; the 0.6 W draw means it will not overload standard fan headers.

What maintenance will the 4020 40mm fan need over time?

Blow dust from the blades and housing every few months; if the sleeve bearing becomes noisy or the 0.6 W motor fails, replace the entire unit as bearings are not user-serviceable.
