Questions about this item

Will the 4-pin connector on this 12 V 0.35 A cable fit the PWM header on my older 1U server board?

The cable uses a standard 4-pin PWM connector that matches the 12 V 0.35 A pinout used by San Ace 4028 fans, so it will seat directly on a legacy 1U header without adapters.

How can I confirm the fan is running at the correct speed after I plug in the cable?

Check the BIOS or hardware-monitoring software for a 12 V 0.35 A fan reporting its RPM through the 4-pin tach signal; a steady reading matching the fan’s rated speed confirms the cable is delivering power and signal correctly.
