  • Two-pin connector simplifies motherboard installation
  • SUNON-built motor delivers reliable cooling for critical hardware

Compact 40 mm server fan

The CAFELE GM1204PQV1-8A is a 40×40×28 mm case fan built for tight server and industrial chassis. It runs on a 12 V supply and draws 2.8 W through a two-pin connector. The slim profile fits 40 mm mounting holes where larger fans cannot be installed.

Replaces worn 4028 two-pin units

This model directly substitutes a failed or noisy 4028-size fan with the same 12 V, 2.8 W rating and two-pin interface. The swap is worthwhile when the original fan has seized, developed bearing rattle or no longer moves enough air for the enclosure. No wiring changes are needed if the header matches.

Handles restricted airflow paths

The 28 mm thickness and 2.8 W motor deliver steady airflow through dense heatsinks or narrow ducts in 1U and embedded systems. It reaches its limit when the chassis demands higher static pressure or greater volumetric flow than a 40 mm frame can provide. Builders needing more cooling capacity must look to larger frame sizes.

Questions about this item

Will the 40×40×28 mm frame and 2-pin connector fit my 12 V fan header?

The fan measures 40 mm square by 28 mm thick and uses a standard 2-pin plug for a 12 V header.

What is the correct way to mount the GM1204PQV1-8A and which step is often missed?

Align the four corner holes with the chassis mounts, secure with four screws, then attach the 2-pin connector to the 12 V header.

When should I plan to replace the 12 V 2.8 W unit?

Replace the fan if bearing noise appears, airflow drops noticeably, or the 2-pin connector becomes loose.
