Bit of a noob here! Why a torque screwdriver? Do the newer hp servers not use cpu latches or are we talking about amd stuff?
Yep, os in the older E5 world the cpu’s went into the socket (in the case of HP they have a plastic guide attached to the cpu to assist) then lock the latches down, then screw down the heatsink onto the whole lot.
In scalable world the cpu gets assembled as a unit with the heatsink, then you place the whole thing on the board (posts and guides) and torque screw the whole assembly down.
I prefer the new way generally as you can easily leave the cpu and heatsink as a single unit, so swapping cpu means no messing around with heat transfer paste.
