1, your notebook is of high quality. The reason why you detected such a high temperature is because Master Lu can't detect the real heat of the dual graphics notebook at all, so you don't have to worry.
As far as I know, the cooling function of your notebook is quite good. If you are worried that the notebook temperature is too high, you can add a cooling fan under the notebook, which can be bought in 30 yuan.
3. I suggest you use Tencent Computer Manager-Toolbox-Hardware Detection to check your computer. Personally, I think it is better than Master Lu, who is out of date.
If you are not satisfied with my answer, you can continue to ask questions or make valuable suggestions. Thank you.
