CPU usage high even when no apps running

My Macair is running extremely. I updated to Sierra Version 10.3.5. Even when there are no apps running CPU usage is around 70%. System processes account for close to 65% and user about 5%.

Kernel_Task shows 200% CPU usage and rest are less than 1 %.

MacBook, macOS High Sierra (10.13.5)
