Replacement Blower Fan for B3510X05B

This 5 V DC blower fan is built to fit the B3510X05B laptop cooling pad. It draws .15 A and measures 35 x 35 x 10 mm, matching the original 3.5 cm form factor. The unit suits owners who need a direct swap for a worn or noisy stock fan.

Thermals and Power in Normal Use

Rated at 5 V and .15 A, the fan runs from the pad’s existing USB or header supply without extra adapters. The blower layout pushes air through the heatsink channels to lower surface temperatures during typical workloads. Each unit is tested before dispatch to confirm it spins up correctly and delivers the expected airflow.

Build Quality and Daily Implications

The package contains one fan sourced from Forcecon, ADDA, Sunon, Kipo or an equivalent maker depending on stock. Buyers must compare the photos with their original part because connector pinout and mounting tab positions can differ between revisions. This item is not for users who need a complete cooling pad assembly or a larger 100 mm case fan.

Questions about this item

How do I install the 35x35x10mm blower fan and which step is often missed?

Align the screw holes of the 35x35x10mm fan with the laptop chassis, connect the 5V .15A power lead to the motherboard header, and secure the screws evenly — the step often missed is verifying the blower exhaust direction matches the original airflow path before tightening.

What maintenance will the B3510X05B cooling fan need later?

The 3.5cm blower fan should be cleaned with compressed air every few months to remove dust from the impeller and heatsink fins; the sleeve or ball bearing is not user-serviceable, so plan to replace the entire unit if noise or vibration increases.

What limit appears first when the 5V .15A fan runs continuously under load?

The 5V .15A power budget caps the maximum airflow, so sustained high temperatures will hit the thermal limit of the blower design before the electrical limit, reducing cooling effectiveness until the laptop throttles.
