I've just measured up a temperature of my laptop's CPU and was a little bit shoked. It is really hot! As hot as I can roast eggs on it :(. Now I’m going to disassemble it and find out why it heats. Hope I will be able to manage with it.
UPD: I fixed it. The reason of heating was in stripes of pressed dust on a radiator. These stripes were blocking internal air from going outside of the laptop. Now (after whole night + half a day of work the temperature of CPU is 44 degrees only.
