high cpu/gpu temerature after installing nvidia drivers
By John Parsons •
I'm running Kubuntu 20.04 on a laptop with an Intel i7-4700mq and a Nvidia GTX 770m.
After the fresh installation , everything worked with the Nouveau driver.
After installing the proprietary drivers Nvidia 390(recommended) the CPU started to overheat. While using nouveau driver the idle temeperature would be 47 , but with nvidia 390 driver idle temperature is around 61.
I tried to switch to Intel via nvidia-settings prime profiles , and via prime-select , but it doesn't work.
The result of ps auxc | grep -i therm

Yep. If you use a more powerful processor, the temperature will go up, as per the Second Law of Thermodynamics.
Intel has no problem with anything under 100C as per
