High CPU Loud fan and strange noises?

Ap

My CPU is almost always over 90 lately even though I have only just started it up. My fan is also making a loud noise. I've already opened it. It hasn't gotten any better. My laptop is also very, very loud.

If it is important. I own an IdeaPad L340 Gaming from Lenovo with a Geforce GTX and a 9th generation Core i5.

Wasn't there any dust?

After what you say I would suspect the fan is defective.

Can you swap the fan as a test?
