Compact 70 mm server fan for tight builds

This 70x70x15 mm cooler runs on 12 V DC and draws 0.17 A, making it suitable for small-form-factor servers and workstation chassis where space is limited. The three-wire connection provides tachometer feedback so the system can monitor rotational speed. It is intended for builders who need a direct replacement for the Cooler Master A7015-33RB-3AN-P1 unit.

Three-wire monitoring with no bundled extras

The fan ships as a standalone component without mounting screws, adapters or control software, so installers must supply their own hardware and configure fan curves in the motherboard BIOS or a separate controller. Buyers who require PWM speed control or a four-pin connector will need a different model.

Highlights

  • Fits 70 × 70 mm mounts for direct replacement
  • 12 V DC input matches standard server rails
  • 17 A draw keeps power budget low
  • Three-wire connector enables speed monitoring

Questions about this item

How often will the sleeve bearing in this 7015 fan need replacement?

Sleeve-bearing fans typically run for several years before noise increases; the 12 V .17 A motor draws little current, so bearing wear is slow under normal server airflow.

What thermal limit appears first when this 70×70×15 mm cooler runs continuously?

The 33 RB motor rating caps sustained speed; once the 12 V supply hits its .17 A ceiling the fan cannot spin faster, so airflow plateaus before the frame overheats.
