Yes, it runs so hot and will cause burnt components.?
No. Just no.
Your computer will shut down on its own if it ever comes close to damaging itself with heat. You have nothing at all to worry about.
Hot to your touch doesn't mean it's too hot for a MACHINE (remember, your computer is just that, a machine).
I'll give you a short excerpt from the Wikipedia article on thermal burns:
The minimum temperature where it can suffer burn in a finite amount of time is 44 °C (111 °F). From 44° to 51 °C (111° to 124 °F), the rate of burn increases by a factor of approximately four with each Celsius degree risen or twice per Fahrenheit degree risen, from six hours down to six seconds. The burn would develop in less than a second if the exposure temperature is at least 70 °C (160 °F)
51 C is pretty much idle temperature for your computer, that is, the insides are sitting at that temperature when it's doing absolutely nothing. Like what you're so afraid of.
These computers will run up to 105C before throttling themselves to keep heat production down, if that doesn't work and temps keep climbing, they'll shut down and refuse to boot back up until things have cooled, plain and simple. THAT, is a computer that has overheated.
Having it sit on your desk doing nothing will not, ever, cause that. You can leave it there until the end of time, and it still won't overheat.
