2. Unscrew the 2 screws from the smaller section of the case and carefully remove it:

4. Unscrew 3 screws from each blower:

6. Remove the 2 small screws securing the sides of the heatsink.

16. Secure the heatsink by tightening the 4 spring-loaded screws in a diagonal pattern, doing only 0.5-1 rotations per screw. Don't worry about overtightening them, they have a mechanical stop, you'll feel it.

20. Reattach the case cover and secure with the 2 screws. Start with the side opposite to where the screws are, it should be a tight fit, putting it in place at an angle helps.

After reassembly, boot the device and monitor temperatures to ensure proper cooling performance. Note that in case of PTM7950 the temperature could improve over the course of several days and multiple burn-ins on max temp are recommended.
