My MacBook Pro running on macOS Catalina is really slow and the kernel task is using 1000% of the CPU !!

I tried all the solutions suggested in MUF How to Fix Your Mac’s “kernel_task” High CPU Usage Bug. I still have the same problem.There is only one solution that I was not able to do exactly like it was mentioned, it is the one suggested by Victor Petterson in How to fix kernel_task CPU usage on Yosemite.

It involves removing the « model identifier ».plist file. I was not able to find the file with my model identifier so I removed all the files in : ../ACPI_SMC_PlatformPlugin.kext/Contents/Resources

After removing the .plist files I have restarted my MacBook and re-enabled the SIP. Now the files are removed and the kernel task still using 70% of the CPU with a maximum speed of fans.

Does anyone have the same problem and was able to find a solution to the kernel task issue which is different from the ones mentioned above ?
