HP 826379-001 CPU cooling fan is a notebook replacement part intended to cool the processor. It is listed as a fan without a heatsink, so the product is the fan component rather than a combined fan and heatsink assembly.
The fan uses a 4-pin connector. The listing names HP ProBook 430 G3, HP ProBook 430 G2 and HP 240 G5 among compatible models. This makes the part relevant for servicing those notebook models when the CPU fan needs replacement.
