Once upon a time, home computers were low-powered enough that they barely needed any cooling at all. An Amiga 500 didn’t even have a heatsink on the CPU, while the early Macintosh got by with a single teeny little fan.
Modern smartphones are far more powerful than these ancient machines, packed with multi-core processors running at speeds of many gigahertz. Even still, they’ve generally been able to get by without any active cooling devices. However, as manufacturers continue to push the envelope of performance, they’ve had to scramble for ways to suck heat out of these handheld computers. Vapor chamber cooling has risen as a solution to this problem, using simple physics to keep your handset humming along at maximum speed for longer.
