I’ve noticed that the laptop’s fan only works for the first few minutes during startup, after which it doesn’t turn on anymore (it probably stops working after the first computer sleep, s2idle). Even though the device gets hot, the cooling remains passive. Sometimes, however, they continue to run even during sleep (s2idle). No difference using different kernels (at least with the last 3 available). Doing a search online, it seems to be a common issue on Linux.
