40mm 12V case fan with double ball bearing

The Fans MGT4012ZB-W20 is a 40mm case fan that runs on 12 volts and draws 0.22 amps. Its double ball bearing construction supports continuous operation in tight chassis locations. The four-wire lead allows speed monitoring and PWM control where the motherboard header provides it.

Suited for compact builds needing a 40mm replacement

This fan fits small-form-factor cases and legacy coolers that require a 40mm frame. Builders who need higher airflow, larger frame sizes or different voltage ratings should look at alternative cooling options.

Questions about this item

What voltage header does the MGT4012ZB-W20 need on my motherboard?

It runs on a 12 V fan header, so the board must supply 12 V.

Will the 4-wire connector on this 4020 fan work with my older 3-pin fan headers?

Yes, the 4-pin plug fits a 3-pin header; the fan will run at full speed without PWM control.
