Laptop fan vibrating

Hey guys i need help i have an hp laptop and today i turned it on and the fan is not making normal like noises at all its not even loud like some would expect but its making a noise that goes like " a fan starting up then ends up with a weird vibration sound " it sound exactly like a strong loud vibrating phone sound any ideas or anyone ever experienced something like this ?

I dont know if tge fan is dying and needs to be replaced or if it needs cleaning even though i checked the back of the lqptop and the fan does not look that much dusty like even a strongly dusty fan wouldnt mqke a qound like that it would just be loud or idk if needs lubrificant hit me up with a solution asap !🙏🙏🙏
