A 40 × 40 × 28 mm 12 V axial fan spinning at 5 000 RPM with Maglev bearing for quiet server or case cooling

  • Maglev bearing cuts friction for silent operation
  • 12 V input runs from 4 V to 12 V range
  • 5000 RPM delivers strong airflow in tight spaces
  • 40 x 40 x 28 mm frame fits compact server chassis
  • 8 W draw keeps power budget low

Compact 40 mm server fan

The SUNON GM1204PQV1-8A is a 40x40x28 mm axial case fan built for 12 V server and industrial cooling. Maglev bearing and a 5000 RPM top speed suit dense chassis and rack environments where space is tight and reliability matters.

Voltage range and power draw

Operating range spans 4 V to 12 V with a rated current of 0.230 A and 2.8 W maximum power. Speed scales with voltage, so the fan runs quieter at lower input but cannot exceed the 5000 RPM ceiling or the 2.8 W limit.

Airflow headroom for small enclosures

At full speed the fan moves enough air for single-board computers, network switches and GPU VRM zones. It cannot cool multi-core server CPUs or high-wattage GPUs; those loads need larger fans or liquid solutions.

Questions about this item

How do I choose between the different versions of this 40x40x28mm fan?

Only the GM1204PQV1-8A model is listed, so there are no alternative versions or capacities to select from.

What does the 5000 RPM rating mean for airflow in my system?

At 5000 RPM the fan delivers high-speed cooling in a compact 40x40x28mm frame, suitable for tight server or industrial enclosures.

What power connector does the 12V 2.8W fan use and what does it limit?

The fan operates on a 12 V supply drawing 0.230 A, so the 2.8 W rating caps the maximum power the header must provide.
