Wait, why would the device get warm during suspend? Or do you mean a different kind of sleep mode? I'm thinking of the state where it just refreshes DRAM to keep its contents (this does not produce much heat at all) and everything else is off: that definitely does not require the cpu fan to run because the cpu is not processing any instructions during that state.
- detaro 5y agoI assume not get warm, still is warm from running beforehand.
- lucb1e 5y agoHmm if that were necessary, then all power states should keep the fan on for a while after running, so a device that was shut down would also keep the fans on and there would be no need to put in a requirements document that the fans must turn off to give the illusion of having shut down? To my understanding though, if no new heat is created (usually mainly by processors like CPU or GPU), keeping the fans on is not necessary in regular laptops or desktops.
