    Dell inspirion 15 7570 fan not spinning at full speed

    Hi

    I have recently installed Ubuntu 18.04.1 LTS. the fan won't spin at full speed causing the system to reach 90C or above. I didn't had this problem with windows. I am also new to linux, please anyone tell me how can I fix it.

    thanks

    The fan speed is controlled by the BIOS. Adjust your settings there if you want a more aggressive fan curve.

    Otherwise you can install lm-sensors and fancontrol if you want to set your own thresholds in software.

    Also the i5-8250u never goes above 2.7Ghz even on light load
