Take proper electrostatic precautions before handling motherboard or processor.

  • Whenever possible, avoid working on a carpeted area, especially in cool, dry areas
  • Dissipate any static electricity by touching a grounded metal object, such as the system metal chassis before working with the system components
  • Use antistatic devices, such as wrist straps before handling any electronic devices

PIB Heatsink / Fan Installation (Initial Installation):

  1. To install the heatsink, place the heatsink on the processor with it centered in the retention frame matching the heatsink clip with the socket mounting lugs (the heatsink should have full contact with the processor). Make sure the retention clip is aligned with the plastic lugs on the retention frame.
  2. Carefully push straight down on the retention clip, one side at a time, until both sides of the clip are hooked to the retention frame lugs. Some force may need to be applied.
  3. Carefully turn the cam lever down.
  4. Connect the fan power lead to the proper connector on the motherboard (refer to your motherboard manual for fan connector location).

Note: Check the installation completely to make sure heatsink is installed correctly before starting the system.

PIB Heatsink / Fan Un-Installation:

  1. Carefully rotate the cam handle (lever) up to relieve force on the spring clip.
  2. Carefully remove spring clip from the frame mounting lug. The spring clip under the cam lever must also be un-hooked.
  3. Gently twist the heatsink back and forth several times to break the seal between the heatsink and processor.

Note: This creates a shear force in the thermal interface. Failure to break the seal between the heatsink and the processor may result in pulling the processor out of the socket, possibly resulting in processor or socket damage.

  1. Gently lift the heatsink away from the processor while continuing to twist back and forth. Unplug the fan power lead from the motherboard.
  2. After removing the heat sink, clean the residual thermal grease from its base using a dry wipe, with the processor still in its socket gently clean the top surface of the processor using an upward rolling motion with a wipe to capture as much grease material as possible. Use care during cleaning to prevent grease contamination from spreading to other components. Change to clean wipes frequently to avoid smearing grease over the processor edge.
  3. When possible, avoid using wet chemicals such as acetone  or alcohol as these chemicals can cause contaminants to flow into the socket area. Look for any remaining grease on the processor edge and remove this grease with a cotton bud or a folded edge of a cleaning wipe.

PIB Heatsink / Fan Re-Installation:

  1. When re-installing the heatsink, re-apply an AMD approved thermal solution to your clean processor. This thermal solution should be applied in a thin uniform layer. AMD has found a 34-35 mm square in a thin layer (approximately 0.06-0.08 mm thick) provides good coverage of the processor lid while not being excessive.

Note: Grease may flow over the edges of the processor and reach the socket if excessive amounts are applied. This is not desirable. For more detailed instructions on thermal grease application, please refer to the instructions provided by the manufacturer of the product you are currently using.

  1. To re-install the heatsink, place the heatsink on the processor with it centered in the retention frame matching the heatsink clip with the socket mounting lugs (the heatsink should have full contact with the processor). Make sure the retention clip is aligned with the plastic lugs on the retention frame.
  2. Carefully push straight down on the retention clip, one side at a time, until both sides of the clip are hooked to the retention frame lugs. Some force might need to be applied.
  3. Carefully turn the cam lever down.
  4. Connect the fan power lead to the proper connector on the motherboard (refer to your motherboard manual for fan connector location).
    Note: Check the installation completely to make sure heatsink is installed correctly before starting the system.
