Has the fan been running? If the fan never runs on your laptop, it's a problem. Most laptop fans run more than the users would like, especially the noisy ones, but no fan at all usually means dead fan and overheating laptop.
The higher the laptop quality, the more likely they use a high quality fan and run it at the lowest RPMs possible to reduce noise. But if your laptop is overheating and you never hear the fan and can't detect any air circulation at the vents, either the fan is dead or there's something wrong with the controller.
If you don't replace the fan or get it working again, you are going to shorten the life of your laptop.
