100% you should never run a computer without a cooler on the CPU. Even with a cooler CPUs can easily get over 60 degrees Celsius very quickly. Without a cooler it’s probably reaching unsafe temperatures (90+ degrees Celsius) almost immediately because it has nothing to dissipate the heat.
Please, leave it turned off until you get the cooler on there so you don’t damage your CPU. 😭
Yeah. What else would I do after work?
