Compact 5 V blower for notebook cooling

This 5 V blower draws 0.14 A and carries the UDQFNKH01 3507 designation. It fits tight notebook chassis where a radial airflow path is required. The small form factor targets service technicians and DIY upgraders who need a direct replacement for an original cooling module. Buyers who need a larger case fan or a PWM-controlled model should look elsewhere.

Low power draw and focused airflow

At 5 V and 0.14 A the fan consumes minimal power from the notebook supply. The blower wheel pushes air through a narrow exhaust slot, concentrating cooling on heat-pipe fins rather than dispersing it inside the chassis. Acoustic output stays modest because the motor runs at low current. No separate power connector or speed-control header is required.

Questions about this item

How do I connect the 5V 0.14A UDQFNKH01 blower to the motherboard header?

Plug the two-wire lead into a 5 V system-fan header; the red wire goes to the 5 V pin and the black wire to ground.

When should I replace the 3507 blower?

Replace the fan when bearing noise becomes audible or airflow drops enough that component temperatures rise under load.
