Compact 40 mm DC fan for targeted cooling

The NIDEC 4020 TA150DC is a square 40 mm frame fan designed for spot cooling on small-form-factor boards or replacement in legacy coolers. It suits builders who need a direct 12 V DC source with a three-wire lead. Buyers who want PWM control or a larger airflow envelope should look elsewhere.

Simple three-wire mounting

The unit uses a standard three-wire connector that plugs into a 12 V header; polarity is fixed by the housing so misconnection is unlikely. Ball-bearing construction tolerates any orientation without leakage risk. No screws are included, so verify hole spacing against your bracket before ordering.

Steady airflow under continuous duty

Rated at 12 V and 0.27 A, the motor draws consistent current during prolonged operation without thermal throttling. Ball bearings maintain rotational stability over long periods better than sleeve alternatives. The lack of speed reporting means the host cannot confirm rpm under load.

Questions about this item

How can I confirm the 40mm NIDEC 4020 TA150DC fan is spinning correctly after installation?

Connect the 3-wire lead to a 12V header, power the system and verify the tachometer signal reports RPM in BIOS or monitoring software; the ball bearing should run without grinding noise.

What comes with the C34792-33 unit and what must I source separately?

The box contains the black 40mm fan with pre-attached 3-wire cable; mounting screws, fan grill or PWM adapter are not included and must be purchased if your chassis needs them.

Which specification distinguishes the available versions of this NIDEC 4020 cooler?

The model C34792-33 is a single 12V 0.27A 3-wire variant with ball bearing and no LED; no alternative voltage, connector or bearing options are offered for this MPN.
