High CPU temps on my Nitro 5

lowrecruit

I'm currently using a nitro 5 an515-43r19v laptop, with a ryzen 7 graphics card and a radeon rx560x graphics card. For a while now i have been noticing that my PC temps were quite high, sitting around 65 celsius or even 70 when idle, and peaking at 83 degrees while running chrome and charging at the same time. While gaming whilst charging, its consistently around 90-95 degrees with the nitrosense auto fan setting and dropping to around 80 with the max fan settings and coolboost on. I visually inspected the air outlets but there doesn't seem to be significant dust buildup. Is there any reason why my temps are so high and is there any way to fix it? Thank you in advance

Just so you know, I have no experience with systems such as yours, but I think the advice I'm going to give would serve just the same: Replace the stuff that sits between the cooling solution and the parts that generate the heat, commonly known as reapplying thermal paste or repasting.

During manufacturing, while things tend to be produced as flat as possible if analyzed under a microscope there'd be peaks and valleys. To ensure proper thermal conductivity between the CPU die (for example) and the copper pipe-vapor chamber situation above it a thermal compound is used. Some sort of grease (or pads for some parts) that connect the two filling those peaks and valleys and help take the heat off of the CPU and onto the cooling solution.

The sooner that happens, the better, because the cooler the CPU, GPU, etc. will be running.

The thing is that the factory stuff is sub-par compared to aftermarket thermal compounds, in other words they conduct heat slower. Replacing that grease for a high end thermal compound, or even liquid metal (an allow with gallium, it's liquid at ambient temps.) will make it so much effective. The only thing you need to know is that some thermal compounds are electrically conductive, so they need not spill to other areas. You'll find plenty of videos on how to properly apply the stuff you choose in YouTube for sure.

That's what's going to make the biggest different in temperatures both idling and under load.

Another option is using software to tweak the parameters of the CPU & GPU so they run at lower voltages or make the fans spin faster at lower temperatures, etc. ThrottleStop is an example of one such program, but the biggest difference comes by far when you replace the thermal grease interfacing the hot components with the cooling solution.

Another thing that comes to mind, firmware upgrade, sometimes they tweak the fan tables in subsequent firmware upgrades to mitigate things like that, you could also verify you're running on the latest one and upgrade if not.
