Questions about this item

How can I confirm the EG60070S1-C080-S99 fan is spinning correctly after fitting it to my Lenovo B50-30?

Enter the BIOS hardware monitor or use a system utility to verify the CPU fan RPM reads a steady value above zero and no fan error appears on boot.

What is included with the EG60070S1-C080-S99 cooler and do I need a separate mounting bracket for a B40-70?

The package contains the original CPU fan with its heatsink and pre-applied thermal interface; the proprietary mounting screws match Lenovo B40, B40-30, B40-45, B40-70, B50-30, B50 and E50 chassis so nothing extra is required.
