Lenovo laptops, and laptops in general, are prone to overheating due to their cramped construction. When running many programs on the laptop, the CPU becomes very hot, which can cause the laptop to shut down. Some newer Lenovo laptops have adjustable fan control, which means the CPU fan speeds vary directly with the CPU temperatures. However, if you want to keep your fan speed at 100% all of the time, you can do so by changing settings in the BIOS.
