System Maintenance

The next way is that you will apply the cleaning method to your GPU. If the CPU has too much dust, it will cause the fan vents to become clogged with dust, and the cooling systems cannot draw in as much air to cool the GPU, leading to heat retention. You should clean the fan vents, removing any dust if possible, to keep the cooling running properly.

1. Prepare a can of compressed air a dust blower and a spray bottle with a small nozzle to remove most of the dust from the fan vents.
2. Thermal resealing with thermal paste can also be a big help in maintaining consistently high temperatures, especially if you're using a high-performance laptop with power-hungry components.
3. However, if you are experiencing extremely high temperatures (around 190 degrees F or more) even when your GPU is idle, it may not be cooled enough. At this point, a thorough system maintenance regimen will be able to fix that.
