Compatible HP ProBook Models

This replacement CPU fan fits HP ProBook 6555B, 6550B, 6455B, 6450B, 6440B, 6540B, 6445B and 6545B laptops. It is designed for owners of those specific models who need to replace a worn or noisy cooling unit. The part matches original specifications GB0506PGV1-A, KSB05105HB, AB88 and 613349-001. Buyers with other notebook series cannot use this cooler.

Single Fan Cooling Limit

The accessory provides one fan to draw heat away from the processor. A single fan can only move a finite volume of air, so sustained heavy workloads may still raise temperatures. The unit does not add extra heat pipes or a larger heatsink beyond the original design. Users expecting desktop-class thermal headroom will find the improvement modest.

Verify Exact Part Number

Before ordering, compare the part numbers on your existing fan with GB0506PGV1-A, KSB05105HB, AB88 and 613349-001. Connector orientation and mounting screw positions must match the original exactly. The supplier notes that fans may come from Forcecon, ADDA, Sunon, Kipo or other manufacturers depending on stock. If the labels differ, contact the seller to confirm fit.
