b) On the new board, set the heatsink with CPU assembly down onto the CPU socket.
c) Use a T-30 Torx driver to tighten the four captive nuts that secure the heatsink to the board standoffs.
Alternate tightening the heatsink nuts evenly so that the heatsink remains level while it is lowered. Tighten
the heatsink nuts in the order shown on the heatsink label: 1, 2, 3, 4. The captive nuts must be fully tightened
so that the leaf springs on the CPU socket lie flat.
