Fans GM1204PQB1-8A 12V 2.6W 40*40*28mm case fan

SKU CH-Y6K8-8AD3N

A 40 mm square server cooling fan delivering 12 V and 2.6 W in a 28 mm thick frame

  • Compact 40 mm frame fits tight server builds
  • 12 V operation matches standard PSU rails
  • 6 W draw keeps power budget low
  • 28 mm thickness suits slim chassis slots

Compact server fan 40 mm

The Fans GM1204PQB1-8A is a 12 V DC case fan built for tight server chassis and industrial enclosures. It draws 2.6 W and fits the 40 x 40 x 28 mm footprint common in 1U and blade systems. Buyers who need a drop-in replacement for a failed OEM blower will find the exact mounting pattern and voltage match.

Upgrade from noisy or failed 40 mm units

The jump is worth it when the original fan has become loud, vibrates or no longer spins at full speed. It replaces any 12 V 40 mm frame with the same 28 mm depth and four-corner screw holes. Builders who require PWM control or a larger frame should look elsewhere because this model is fixed-speed and size-constrained.

Questions about this item

Will the 40 mm square frame and 28 mm depth fit my server chassis?

The fan measures 40 mm by 40 mm with a 28 mm thickness, so verify your chassis has a matching 40 mm mounting pattern and at least 28 mm clearance.

Which wire connects to the 12 V supply on this GM1204PQB1-8A?

Connect the red lead to 12 V and the black lead to ground; reversing them will prevent the fan from spinning.
