Use Master Lu or some other software to test the temperature, and see the temperature change in normal use. Also, do you feel that the notebook is hot after several hours of use? Maybe it's the fan.

Please don't clean up the garbage frequently, too often will cause damage to the hard disk, and then clean it normally for a week when you feel that the capacity of the C disk is large.

4 suggestions: take the virtual memory to the non-C drive, the size is 1.5~2 times the memory. It's just another disk with a large capacity. There are tutorials online, and they are very fast. Tell me about it. Right-click My Computer Properties, Advanced System Settings, Advanced Performance Settings, Advanced Change, set drive C to 0, then select another disk system management size, enter two points with the same value, and confirm the restart.
