| + | ::: |
| + | |
| + | #### Tools Required |
| + | - PTM7950 (30x30mm, 0.2-0.25 mm thick) or Noctua NT-H2 (or something similar, don't go lower) |
| + | - Phillips-head screwdriver (small and small-ish) |
| + | - Isopropyl alcohol (90%+ recommended, 70% is okay) |
| + | - Lint-free cloth or coffee filter |
| + | - Optional: electrical tape, 0.5 mm thermal pads (Gelid GP Ultimate or better) |
| + | |
| + | #### Safety Precautions |
| + | - Ensure device is powered off and power cable is disconnected |
| + | - Work on a static-free surface |
| + | - Keep track of all screws - consider using a tray |
| + | |
| + | ### Step-by-Step Instructions |
| + | |
| + | #### Disassembly |
| + | 1. Turn the device upside down and remove both rubber feet. |
| + | 2. Unscrew the 4 screws from the larger section of the case and carefully remove it. |
| + | 3. Locate and remove the tape sealing the heatsink to the blowers. |
| + | |
| + | #### Blower Removal |
| + | 4. Unscrew 3 screws from each blower. |
| + | 5. Gently move the blowers to the sides (no need to disconnect them). |
| + | |
| + | #### Heatsink Removal |
| + | 6. Remove the 2 small screws securing the sides of the heatsink. |
| + | 7. **IMPORTANT**: Gradually loosen the 4 spring-loaded screws holding the heatsink in a cross pattern (diagonal sequence), turning each screw only 1-2 rotations at a time. |
| + | 8. Once all screws are loose, **gently** rock the heatsink side to side to break the thermal paste seal. |
| + | 9. Carefully lift the heatsink straight up and away from the APU. |
| + | |
| + | #### Cleaning and Preparation |
| + | 10. Clean the old thermal paste from the APU using isopropyl alcohol and a lint-free cloth. |
| + | 11. **CAUTION**: Be extremely careful around the small capacitors near the APU - avoid excessive cleaning in these areas, it's okay if there is still some thermal paste there. |
| + | 12. Allow the APU to dry completely (a couple of minutes). |
| + | |
| + | #### Applying New Thermal Solution |
| + | 13. Apply your new thermal interface: |

| + | 14. Verify all thermal pads for RAM and VRMs are present and properly positioned. Optionally replace RAM thermal pads as well. |
| + | |
| + | #### Reassembly |
| + | 15. Carefully align and place the heatsink back onto the APU. |
| + | 16. Secure the heatsink by tightening the 4 spring-loaded screws in a diagonal pattern, doing only 1-2 rotations per screw until all are equally tight. |
| + | 17. Reattach the 2 small screws on the sides of the heatsink. |
| + | 18. Return the blowers to their original positions and secure with their 6 screws. |
| + | 19. Replace the sealing tape between the heatsink and blowers (if it's too damaged, electrical tape is fine). |
| + | 20. Reattach the case cover and secure with the 4 screws. |
| + | 21. Replace the rubber feet. |
| + | |
| + | ### Testing |
| + | After reassembly, boot the device and monitor temperatures to ensure proper cooling performance. |
