Macbook always overheats when closed using external display
Is there any way of stopping the macbook overheating and throttling performance when closed using an external display?
Is it possible to turn off the laptop display when an external display is plugged in?
After 1-2 hours of using the laptop closed the fans start to spin up and the processor is throttled so badly that typing in a terminal is slow and any application takes several seconds to respond to clicks. I unplug from my display and use the laptop open and it stops spinning and performance goes back to normal using the same applications.
I either need to be able to run with the laptop open but the screen not in operation so that no application open to there or for a way to prevent this overheating which seems to be a massive design flaw. I can even point a fan at the laptop but this is still not sufficient to cool the device with the lid down.
