your laptop might need a good cleaning. dust buildup can mess with fans. maybe try blowing air through the vents. sometimes you can use usb cooling pads to help keep a laptop cool when the fans are not working properly.
I seem to recall that I heard a fan or something spinning in my HP Pavilion 2000 laptop for years. Now, I hear nothing spinning and I notice the laptop gets very hot after a few minutes especially when re-charging the battery. Do laptops have small fans to ventilate the fan and why do I no longer hear a spinning sound? Maybe I heard the Hard Drives spinning?
