Laptop platforms with built-in cooling fans are also sold.
That said, it can’t hurt, but I’m not saying it’s something that all laptops need.
My almost-five-year-old laptop runs hot, and I’ve never done anything special to keep it cool – just made sure that the vents are unobstructed and the fan is running.
(Then again, a relative who bought the same model at the same time had his fail two years ago…)
