I don't think overheating laptops has ever popped up in any conversation I've had but recently, 3 different people talked about it on 2 consecutive days. Weird. A friend puts a thin book under her laptop to remove the laptop's contact with the table surface, and hopefully improve air circulation to cool down the machine. Another friend spoke about space balls, which I thought referred to the spoof Star Wars movie but were actually tiny spherical props (patented in Singapore too). What this boiled down to is paranoia on my part, so I'm now typing on my elevated laptop, which I'm propping up with believe it or not, pill boxes.
