Compatible Toshiba C850 C855 Cooling Fan

This replacement CPU cooling fan fits Toshiba C850, T05B, T03B, C855 and C855D laptop models. It uses the KSB0505HB-BK48 4pin connector for direct motherboard attachment. The part is supplied new and each unit is tested before shipping to confirm it operates correctly.

Drop-In Fit for Existing Heatsink Assembly

The fan connects to the existing 4pin header without rewiring or adapter cables. It reuses the original mounting points on the heatsink, freeing you from sourcing a full cooling module. Installation only requires opening the chassis and swapping the faulty fan unit.

Sustained Operation With Tested Reliability

Every fan is individually verified to spin up and maintain airflow under continuous load. The 9-month warranty period reflects the supplier's confidence in long-term performance. Buyers needing a different connector pin count or a complete heatsink assembly should look elsewhere.
