Asus TUF FX504 I5-8300H experienced overheating following thermal paste replacement and surface cleaning.
Hello. My laptop has been with me for about two years. About nine months ago I realized it was overheating when it got warm during idle—around 90°C. I checked inside, found the thermal paste missing, cleaned the fans and replaced it with a generic brand. Now everything works fine, and the device stays under 65-70°C even when running heavy tasks. Recently, the same issue resurfaced: it heats up to 85-90°C at startup. I’ve tried a cooler pad, but the problem persists. According to HWMonitor, the GPU stays around 65-70°C during load while the CPU hits 90°C at start. What might be going wrong?
thermal throttling might stem from improper mounting pressure—either too much or too little can disrupt contact between the CPU/GPU and cooling plate. another approach is adjusting the CPU/GPU settings to "performance" instead of quieter modes like "silent" or "balanced," which lowers power delivery and can extend boost time slightly, albeit at a marginally slower clock speed. if these solutions fail, consider undervolting with throttle stop, which often provides significant temperature flexibility.
