I am using an old laptop and doing heavy processing that needs high CPU usage for a long time (~30mins - 2hours). When the process puts heavy load on CPU for a long time, CPU overheats and computer shuts down. I don't want to use a cooler/stand because I am carrying this laptop around and working outside home.
Is there a way/application that I can limit CPU usage of a process in Windows?
Note: Setting the priority of the process from task manager does not work.
Note 2: Fans are clean.
