There are things you can do to get the Pi to run cooler . First use Putty to SCP in to the Pi . After running as pi then password max2play you should be given a command line .
Type in sudo apt update
Then press return .
When it stops reading the updates it should tell you how many files it can update .
Then again on the command line type sudo apt upgrade . It will then read and compile the update and ask if you want to go ahead Y/N pres yes and this should start the update process . Once this finishes and the screen has reurned to command line type
Once the Pi has renooted this should have updated the kernal and all files and it will run not as hot as before. I would also suggest that you buy something like the flirc case for the Pi 4 as this is very effective at getting the Pi 4 to run cooler .
