70×70×20mm 12V PWM case fan

The NDLIULEI DV07020B12U is a 70×70×20mm case fan that runs on 12V and draws .70A. It uses PWM temperature control to adjust speed based on system heat. The compact frame suits small-form-factor builds and replacement scenarios.

Builders with 70mm mounting points

This fan fits chassis or heatsinks that accept a 70×70×20mm footprint and a 12V PWM header. It is not suited for builds that require larger frame sizes or higher current ratings. Buyers without a 4-pin PWM header cannot use the temperature-control function.

.70A current draw at 12V

The .70A rating determines whether the motherboard header or fan controller can supply enough power. Exceeding the header limit risks instability or damage. Check the header specification before installing.

Questions about this item

Will the 70×70×20 mm frame fit my chassis fan slots?

The fan measures 70 mm square by 20 mm thick, so it matches standard 7020 mounting holes.

How do I connect the PWM lead for temperature control?

Plug the four-pin connector into a 12 V PWM header on the motherboard; the board then varies speed automatically.

When should I expect to replace the 0.70 A fan?

Plan a swap when bearing noise appears or airflow no longer keeps component temperatures in check.
