Compatible Sony SVT15 Models

This CPU cooling fan fits the Sony SVT15 series including the SVT15115CXS, SVT151A11L and SVT15112CXS models. It is a new replacement part manufactured by DELTA under model KSB05105HB. The unit uses a four-wire, four-pin connector and operates at DC 5V with a 0.32A current draw.

Direct Replacement for Original Fan

This component replaces the factory-installed cooling fan in the listed Sony laptops. The jump is worth it when the original fan becomes noisy, fails to spin or causes thermal throttling. A 100% factory test confirms the replacement meets the original specifications before it ships.

Cooling Capacity and Headroom

The fan maintains the thermal envelope designed for the SVT15 platform under normal workloads. It runs out of headroom if the heatsink fins are clogged with dust or if the thermal interface material has degraded beyond what the original airflow can compensate for.

Questions about this item

Will the 4-wire 4-pin DC 5V 0.32A connector fit the Sony SVT15 motherboard header?

Yes, the fan uses a 4-wire 4-pin DC 5V 0.32A connector that matches the original Sony SVT15 motherboard header.

Which screw holes line up when replacing the KSB05105HB fan in the SVT15 chassis?

The KSB05105HB is built to the original factory layout, so its mounting holes align with the existing SVT15 screw points — reuse the original screws.

How often should the DELTA KSB05105HB bearing be cleaned or the fan replaced?

Clean dust from the heatsink and fan blades every 6–12 months; replace the unit if bearing noise appears or airflow drops noticeably.
