@elixwhitetail, not everyone have a brand new computer, I got a laptop that is about 6 years old. I got 4GB of ram, and a core i3. My cooler is not that good, so yes, it can be harmful.
It is not because today we have skilled computers that we have to insult other ones.
My CPU's a Pentium D 925. That's the last gasping days of the NetBurst microarchitecture, which predates Core 2. I built this machine from parts made in 2006. IT'S FUCKING FINE.
Clean your laptop's air vents with a can of compressed air if heat is an issue. If you have inadequate cooling, you're failing to maintain proper operating conditions to start with, so it's your fault.
