!!!!!! They're extremely hot. The CPU idle temp for laptops is less than 40 C, for GPU is less than 50 C (if both CPU and GPU share the same heat pipes) and HDD is around 35 C. When mobile CPU(s) exceed over 90-95 C, the system will crash itself and restart. Gaming would be horrible in this system. Something is seriously wrong. Is this a new laptop? Are you using it after a long time?
Dis-assembling laptop might void warranty. Are you blocking the vents under/side of the laptop? Almost all laptops take air in from the under and the CPU/GPU fan pushes them through side ways. Never use laptop on a surface which has no room for air to move between that surface and the downside of the laptop.
If you're using in the correct way and still get high temperatures, claim for the repair/replacement under warranty..
