Hi Daria1996:
It should be fine as long as your computer has good ventilation. If this is a laptop it will use your battery quicker of course.
You should be able to choose how many cores you want the chess engine to use (so using less cores won't heat up the computer as much but will analyze slower).
Recently, I use [scid vs pc] chess program to see 5~6 lines for each move, and it helps me a lot.
But the only problem is CPU usage rate,,
When I run the program, CPU usage rate of my laptop is over 50%..
Do I have to stop using it? or is it not a serious problem?
