Laptop is getting hot in sleep mode.

In Windows I set power button for sleep mode. So, I send my laptop to sleep and display is off but I hear that vents keep working. So even after night I feel that laptop is warm. Couple times when I put my laptop in backpack and get it out of there I felt that laptop is so hot that I even can’t touch it, so it could be burnt.

Windows, drivers and Razer apps are updated to latest versions. Windows power troubleshoothing doesn’t help.
