DBTLAP Laptop CPU Cooling Fan

This replacement cooling fan is designed for laptops using the EF60070S1-C140-G9A K5703G part number. It operates at 5V with a rated power of 1.90W to dissipate heat from the processor. The unit is supplied new and individually tested before dispatch. It serves as a direct swap for a worn or noisy original fan.

Suitable for owners matching the exact part number

This fan suits repairers or owners who have confirmed their laptop requires the EF60070S1-C140-G9A K5703G model. It is not for buyers who cannot verify the part number against their existing hardware. Users needing a different voltage, connector layout, or mounting screw pattern should look elsewhere. Compatibility cannot be assumed across similar-looking units.

Critical specification: 5V 1.90W rating

The 5V 1.90W electrical rating is the single figure that determines whether this fan matches the laptop's thermal design and motherboard header. A different voltage or wattage will not run correctly and may cause damage. Verify this value on the original fan label before ordering. No other specification overrides this requirement.

Questions about this item

How do I install the EF60070S1-C140-G9A K5703G fan and what step is often missed?

Compare the connector and screw holes to the photos before fitting; the most common mistake is ordering without verifying the part number matches your laptop exactly.

What maintenance will this DC5V 1.90W cooling fan need later?

Periodically clean dust from the blades and vents with compressed air; the fan itself has no user-serviceable parts and runs until bearing wear eventually requires a full replacement.

What limit appears first when this 5V 1.90W fan runs under sustained load?

The 1.90 W power ceiling caps maximum airflow, so thermal headroom hits its limit before the 5 V supply or mechanical speed ceiling becomes the bottleneck.
