A bit late to this party/thread (came here thru google).
I’ve been running Unreal Engine 4.8 the entire day (warm day) and my fan seems absolutely wasted. (I would even go as far as saying: damaged)
Hadn’t noticed it during the day cause I had music on , but now , in the evening , when all is quiet , my macbook pro seems to have picked up a new (ticking/rotating) sound in the fan. Not sure if it’s temporary.
Just did a reboot and it’s still there.
And, rest assured, my macbook was almost soundless before I started playing around in UE.
Also , when I boot unreal engine , the process eats about 600% of my cpu … especially during lightmass calculations.
So - not sure if I’ll be running UE again on my macbook… seems to put the hardware in too much strain …
