Targeted Switch Cooling

This 40x40x20mm DC12V case fan is built for H3C 3600 5600 S5500 network switches. It draws 0.15A through a 3-wire power connector and uses a 2-ball bearing for reliable airflow in rack-mount chassis.

Direct Delta 4020 Replacement

The EFB0412HHD R00 matches the Delta 4CM 4020 form factor and pin-out, so it slots into the original mounting points without adapters. The jump is worth it when the stock fan develops bearing noise or fails to spin up at 12V.

Compact 3-Wire Integration

The 40mm square frame fits tight switch bays and leaves adjacent slots free for cabling. The 3-wire lead reports speed to the chassis monitor while the 2-ball bearing reduces maintenance compared with sleeve alternatives.

Domande su questo articolo

Will the 40×40×20 mm frame fit the H3C 3600 5600 S5500 switch chassis?

The 40×40×20 mm dimensions match the Delta 4020 form factor specified for H3C 3600 5600 S5500 switches.

How do I connect the three-wire lead to the switch fan header?

Align the keyed 3-wire connector with the switch fan header pins — red to 12 V, black to ground, yellow to tach — and press straight in.

When should the dual-ball bearing fan be replaced in continuous operation?

Dual-ball bearings typically run 50 000 hours at 40 °C; plan replacement once airflow drops or bearing noise appears.
