Replacement Fan for Delta BSB05505HP

This DC 5V 0.4A cooling fan is built to match the original Delta BSB05505HP CT02 part number. It connects through a four-line motherboard header for direct power and speed control. The unit is supplied new and individually tested before dispatch. It serves as a direct swap for a worn or noisy laptop cooler.

Fits Delta BSB05505HP CT02 only

Buyers must confirm the exact part number printed on their existing fan before ordering. The four-line connector and voltage rating are specific to this Delta model and will not fit other laptops or generic coolers. Technicians who cannot verify the part number should seek confirmation first. This item is not a universal cooling pad or an upgrade kit.

Four-line 5V 0.4A connector

The electrical interface is a four-pin header delivering 5V at 0.4A, which determines both compatibility and control behaviour. Matching this connector layout and current draw is the single specification that decides whether the fan will operate correctly. No other voltage or pin arrangement is supported by this part.

Questions about this item

How do I install the BSB05505HP CT02 fan and what step do people often miss?

Match the 4-line connector to the motherboard header exactly as shown in the photos; the step many miss is verifying the part number against the old fan before fitting.

What maintenance or replacement will the DC 5V 0.4A cooler need later?

The fan is a single moving part tested before shipping; expect to replace the whole unit when bearing noise or airflow drops noticeably.

What limit appears first on the Delta BSB05505HP CT02 under sustained use?

Continuous operation at 5 V 0.4 A will eventually hit bearing wear, so the thermal limit shows up as reduced RPM before outright failure.
