You literally gave us NO info beside being a notebook and having an Intel CPU with integrated graphics.
If it's old, it might be time for new thermal paste and a thorough cleaning. If it's new, you might have got a crappy cooling solution as almost all notebooks have. If it's a new symptom, you need to clean it as well.
When buying a new notebook most people only care about the CPU, GPU, RAM and Storage brand, model and performance. Not many care to look for info about its cooling system.
As dotas1 mention already, notebooks (new, old, cheap or even many expensive ones) usually come with a crappy cooling solution. A solution which at best, will allow you to keep the cpu and gpu from metling down the rest of the system. And of course always at the cost of high fan noise.
