  7. Scrape the thermal compound application from the heatsink using a plastic putty knife. Scrape the thermal compound parallel to the machined grain, as shown. Scrape the thermal compound parallel to the machined grain, as shown.
    • Scrape the thermal compound application from the heatsink using a plastic putty knife.

    • Scrape the thermal compound parallel to the machined grain, as shown.

  8. Wipe the remaining thermal compound off of the heatsink with an ispropyl alcohol pad. Wipe the thermal compound parallel to the machined grain, as shown. Continue this process until no thermal compound residue remains on the heatsink.
    • Wipe the remaining thermal compound off of the heatsink with an ispropyl alcohol pad.

    • Wipe the thermal compound parallel to the machined grain, as shown.

    • Continue this process until no thermal compound residue remains on the heatsink.

  9. Unlatch (2) CPU retention release levers Unlatch the 'unlock' retention lock first. Unlatch the 'lock' retention lock second.
    • Unlatch (2) CPU retention release levers

    • Unlatch the 'unlock' retention lock first.

    • Unlatch the 'lock' retention lock second.

    • Press the retention rods down and push them towards the CPU. Allow the retention rods to slowly lift.

    • CPU retention release levers are spring loaded. Apply slight pressure as they lift to avoid injury and damage.

  10. Lift the CPU retention bracket.
    • Lift the CPU retention bracket.

    • Allow the CPU retention bracket to pivot, and let stand vertically.

  11. Grasp the CPU by its sides.
    • Grasp the CPU by its sides.

    • Lift the CPU from its socket.

  12. Wipe the top of the CPU with an ispropyl alcohol pad to remove the thermal compound residue. Multiple passes may be needed. Continue until all the thermal compound residue has been removed. Multiple passes may be needed. Continue until all the thermal compound residue has been removed.
    • Wipe the top of the CPU with an ispropyl alcohol pad to remove the thermal compound residue.

    • Multiple passes may be needed. Continue until all the thermal compound residue has been removed.

  13. Orientate the CPU so that the arrow printed on the CPU aligns with the arrow printed on the CPU retention housing, as shown. Orientate the CPU so that the arrow printed on the CPU aligns with the arrow printed on the CPU retention housing, as shown.
    • Orientate the CPU so that the arrow printed on the CPU aligns with the arrow printed on the CPU retention housing, as shown.

  14. Lower the CPU directly onto its socket, as shown. Lower the CPU directly onto its socket, as shown.
    • Lower the CPU directly onto its socket, as shown.

  15. Close the CPU retention gate. Ensure the 'lock' CPU retention lever is on top of the CPU retention gate lip, as shown.
    • Close the CPU retention gate.

    • Ensure the 'lock' CPU retention lever is on top of the CPU retention gate lip, as shown.

  16. Lock the CPU in its socket. Close both retention levers. Close the 'lock retention lever first, and then the 'unlock' retention lever.
    • Lock the CPU in its socket.

    • Close both retention levers. Close the 'lock retention lever first, and then the 'unlock' retention lever.

  17. Apply thermal compound to the top of the CPU using the 5-dot method. Place 0.2 grams of thermal compound on each CPU corner. Drag residue towards the center of the CPU. Place 0.2 grams of thermal compound on the center of the CPU.
    • Apply thermal compound to the top of the CPU using the 5-dot method.

    • Place 0.2 grams of thermal compound on each CPU corner. Drag residue towards the center of the CPU.

    • Place 0.2 grams of thermal compound on the center of the CPU.

    • 0.2 grams is 'about' 1 hash mark tick on the 1 gram CPU thermal compound syringe. Click here for more syringe tips and information.

  18. Align the rear (2) heatsink screw posts with the CPU retention post holes, as shown. Align the rear (2) heatsink screw posts with the CPU retention post holes, as shown.
    • Align the rear (2) heatsink screw posts with the CPU retention post holes, as shown.

  19. Lower the heatsink onto the CPU. Pivot the heatsink forward so that the front two screw posts mate with the CPU retention post holes, as shown. Pivot the heatsink forward so that the front two screw posts mate with the CPU retention post holes, as shown.
    • Lower the heatsink onto the CPU.
