Laptop moved during operation and the fan made strange noises?

When I moved my laptop during operation, which is normal when you have a mobile PC, the fans made an unhealthy sound, the housing also vibrated, a sound like as if this fan was rotating against something inside the whole time. Would be really good to know why. LG

The high-speed fan, as a gyroscope, opposes the sideways movement. As a result, the fan wheel moves a little in the shaft bearings and the fan blades rub against the air guide nozzle.
