I cannot believe these are genuinely overheating even if the fan is broken.. it would take longer than 5 minutes to bake the SoC, just not enough thermal energy to saturate the block of aluminum within that time. I’m going to assume that the SoC is around 5watt TDP.. it’s actually probably less like 2.5Watt TDP... but even at 5 watts it wouldn’t be enough thermal energy to saturate that block within 2-5 minutes...
That is unless... the ESCs are thermally connected to the same HeatSink.. than yes that would saturate the block way more rapidly I could see even with a functioning fan that may be too much at that point to last an entire battery.l before overheating. but if the SoC and the ESCs are not thermally connected, it shouldn’t be baking the SoC.. infact the air intake is behind the gimbal which acts as a bit of a scoop that should be enough air flow at speed to cool it off without a fan.. the fan is there in same way a modern car has a fan on radiator.. mostly there when there is no air flow such as stationary or in slow traffic.. doesn’t need to run all the time and likely won’t as long as the temps are sustainable. My gaming computer does this too, as long as everything is cool enough all the fans stop, and has a very quiet fab curve.. infact I can game on my GPU for a good 5 minutes at 4K high settings before the fan comes on because that’s how long takes me to pass thermal threshold.
So long story short, something really wrong... either ESCs are thermally connected to the SoC... the app is misreading tempatures and shutting the drone off, the drone is misreading tempatures ir there is no thermal paste between the heatsink and the SoC and surrounding parts and heatsink cannot absorb any thermal energy because of that.
