SKU CH-Z3E8-QA42P

A 12 V DC case fan measuring 80 by 80 by 25 mm with a 3-pin connector and 1.7 W power draw

  • 12 V DC power for efficient low-energy cooling
  • 7 W draw keeps system power budget low
  • 80 mm square frame fits standard 80 × 80 mm mounts
  • 3-pin connector enables direct motherboard speed control

EE80251S1-D170-F99 80 mm case fan

This 80 mm square fan runs on 12 V DC and draws 1.7 W through a 3-pin connector. It is built for server and workstation chassis that require a slim 25 mm profile. The unit suits builders who need a direct replacement for an 80x80x25 mm slot.

1.7 W power draw and 3-pin control

At 1.7 W the motor delivers steady airflow for moderate component densities. The 3-pin interface provides basic voltage regulation but no PWM speed curve. It will not satisfy builds that demand PWM control or higher static pressure for restrictive heatsinks.

Questions about this item

Will the 3-pin connector on this 80 mm fan work with the 4-pin header on my older motherboard?

Yes, the 3-pin plug fits a 4-pin header; the fourth pin simply remains unused and the fan runs at full 12 V speed.

How can I confirm the EE80251S1-D170-F99 is spinning correctly after installation?

Check the BIOS hardware monitor or a fan-control utility — it should report an RPM value for the 3-pin header once the system boots.
