Product: HP EliteBook Revolve 810 G2 Tablet
Operating System: Microsoft Windows 10 (64-bit)

Fan made bad noises upon startup. Shut it down and rebooted. Same thing. After about 4 min fan stopped all together. (I never got an actual error code). I replaced fan and heatsink as one unit with OEM part.  Upon start up after replacing it I now get a 90b error.  I find nothing online other than referencing dirty fan as the cause. There's no dirt here. Connections all seated well and I see nothing obvious to be the cause. I'm stuck.
