Installation Notes

Questions about this item

How do I confirm the fan is spinning correctly after installing it in my HP 840 G1?

Enter the BIOS hardware monitor or use HP's built-in diagnostics to verify the CPU fan RPM reads above zero and rises under load.

What comes in the package and do I need a separate heatsink or thermal paste for the ZBook 14 G2?

The box contains only the CPU cooling fan assembly; the existing heatsink is reused and fresh thermal compound must be supplied by the installer.
