Most laptops have cooling fans that blow air over heatsinks for CPU and GPU. Over time, dust can collect and reduce cooling. At my former work IT bought a large batch of Thinkpads that were particularly prone to overheating (and crashing) on warm days due to accumulated dust. Fortunately it was relatively easy to remove the keyboard to expose the cooling fan and ducts. A few blasts of canned air would release a cloud of dust and give you a month or two before a repeat was required. Newer Thinkpads didn't suffer from this problem, so perhaps laptop designers have found ways to prevent accumulation of dust.
Mine had fan vents on the bottom and the rear. Having one on its bum meant that you couldn't actually sit the laptop on your lap without blocking a crucial vent. You also have connectors sticking out in stupid places. It makes you wonder what kind of idiot designed it.
