overworking my processor

[teckachick]

problem,
I bought a laptop to install linux. it has a good processor,core 2 quad, good memory, 4gb and a good hard drive. I installed zorin and everytime i run it, the fan in my processor is non-stop and there was alot of heat. the other day I put the original drive into the laptop with windows 7. the processor ran cool and the fan wasn't non-stop. it ran idle for a while and didn't overheat. to rule out the hard drive I installed Mint on the old drive it came with. it ran hot again.

tell me is there some setting in linux that overworks the processor? if not what's wrong?

Pop up a terminal and type top. This will tell you what the top running process is and how much CPU it is using. What are the top running processes when you run Linux?
