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.
Is It Worth Repairing?

Frequently Asked Questions
How much does thermal paste replacement cost for a ASUS ROG Strix G16?
DIY parts run $10–$20. An independent shop charges $49–$89 including labor. Official ASUS service costs $79–$129. The DIY route saves the most but you take on the risk of further damage; shops are the middle ground; official is the safest if warranty matters.
How often does thermal paste actually need to be replaced?
Stock thermal paste typically degrades after 3–5 years of moderate use, faster under heavy gaming or compute loads. Symptoms: CPU temperatures climbing 10–20°C above normal under load, fans constantly at max RPM, throttling under workloads that used to run cool. Premium pastes (Arctic MX-6, Noctua NT-H2) last 5+ years; budget pastes degrade faster.
How long does thermal paste replacement take and how hard is it?
Plan on about 45 minutes for the work itself, rated Moderate (6/10). First-time DIY attempts typically take 50–100% longer because of unfamiliar parts and tools. At this difficulty, take your time and plan to do it in good lighting — small parts are easy to lose.
What warranty options come with each repair path?
DIY: no labor warranty — the parts carry their own (usually 30–90 days from the supplier). Independent shops typically offer 30 days on parts and labor. ASUS official service comes with 90 days. If keeping the manufacturer warranty intact matters to you, the official route is the only one that does that — third-party work generally voids any remaining manufacturer coverage.
Is repairing my ASUS ROG Strix G16 worth it vs replacing it?
Your ASUS ROG Strix G16 is worth roughly $1,300. A shop thermal paste replacement costs $49–$89, which is about 5% of device value. At this ratio, repair is the clear winner — you save more than 65% vs replacement.
