Nvidia Backend using a LOT of CPU.

I really don't think 50% to 80% CPU usage is normal when my laptop is on idle.

Here's an example:

The fan is constantly running at full speed and the laptop is getting hot, need a fix for this please.

Not sure why you posted under this section because it is very typical for the geforce experience to use that much of your processors resources because you are most likely not fulling exiting out of it. When it just sits there in the task bar it pretty much just sits there checking for updates etc and keeping your gaming profiles and what not. But when you actually open it then that is when the usage from it gets really nasty I have noticed on all of my own person systems. Just make sure that you fully exit out of it each time that you start it. Also make sure you don't have it in your MSCONFIG start up list. So the cpu usage is typical for that applications.
