Step-by-Step DIY Guide
Follow these steps carefully. Take photos at each stage for reference during reassembly.
Power off and open the laptop
Shut down your ASUS ROG Strix G16, unplug it, and remove the bottom panel. Disconnect the battery.
Remove the heatsink
Unscrew the heatsink in the reverse order indicated by the numbered screws (usually 4–6 screws over the CPU and GPU). Disconnect the fan cable if it is attached to the heatsink assembly.
Clean old thermal paste
Use a lint-free cloth with 90%+ isopropyl alcohol to wipe both the CPU/GPU dies and the heatsink contact surfaces until they are shiny and residue-free. Do not use paper towels — they leave fibers.
Apply fresh paste and reinstall
Apply a rice-grain-sized dot of quality paste (e.g., Thermal Grizzly Kryonaut, Noctua NT-H1) to each die center. Do not spread it — the heatsink pressure will do that. Reinstall the heatsink, tightening screws in the numbered order in a cross pattern.
Test temperatures
Reconnect the battery, boot up, and run a stress test (Prime95, Cinebench). Monitor temps with HWInfo or iStat Menus. Expect 10–20°C improvement over dried-out factory paste. Idle should be under 50°C and full load under 90°C.
