Access your motherboard by removing whatever cover or panels needed. Not all barebone/chassis/cases are all the same. The examples shown here may not match your system, but the procedure is similar.

  1. Access your System's Motherboard

  2. Remove Air Shroud (if system has it installed)
  3. Remove heat sink off the CPU
  4. Dismount CPU hold-down frame
    There are two clips that hold down the CPU.
