I live near a river and people here say that copper turns black because of the air. My laptop died recently after 5 years of use and when i opened it, i saw the pipes turned black. Is this bad? Does it effect the cooling power of my laptop? Because i was planning to buy another laptop with 800$. But if this is an serious issue then i would not spend that much money for something that will have broken heat pipes in 2 years. Please help me out. Is this bad for the cooling system? I can't monitor the heat as my laptop is dead. As far as i know it only over heated because of dust. So am I risking my money if i get an expensive (for me at least) laptop? Help please. You can see the photos, almost all of it is black like burnt. Only a little area underneath still has the original color.
