Compact 50mm Delta fan for tight builds

The Delta AUB0512L is a 50mm square fan with a 25mm thickness. It runs on 12V and draws 0.12A through a standard three-pin connector. Ball bearings support continuous operation in small form-factor coolers or rackmount chassis.

Suits builds needing a slim 50mm replacement

This unit fits coolers and enclosures designed for a 50 by 25mm footprint and a three-pin header. It is not for builders who need a larger frame, higher airflow, PWM speed control, or integrated lighting.

Simple three-pin swap in most coolers

Installation requires matching the three-pin plug to the motherboard or controller header and securing the fan with standard 50mm mounting holes. The main issue is verifying that the existing cooler accepts a 25mm thick frame and that the header supplies 12V.

Questions about this item

Will this 50mm fan mount on my existing 5025 heatsink?

The fan is a 50 by 25 millimetre square frame, so it matches the standard 5025 mounting holes on compatible coolers.

Can I run the 12V 0.12A three-pin fan on an older motherboard header that only supplies 5V?

At 5V the motor will spin more slowly and may not start reliably; the fan is rated for 12V operation.

How do I confirm the ball-bearing fan is spinning at the correct speed after installation?

Connect the three-pin connector to a motherboard header and monitor the RPM reading in BIOS or fan-control software.
