I don't think so ,

before 3.18 we had a high cpu utilization (25 to 30%) that was fixed by recent

apple osx 10.10.2 update , ( the problem was solved temporarily by disabling

some gpe ) but there wasn't any fan or heat problem .

After the osx 10.10.2 update ( was during linux 3.18 ) the fan spins up ( very

high rpm )on very little cpu utilization ( watching a video in chrome ) & then

spins down when idling .

on 3.14.33 it's the reverse , the fan doesn't spin up but the temperature rises

to 90 degree celsius ( also while watching videos on chrome ) , which is

harmful to the laptop .

the solution would be something in the middle ,

BUT PLEASE HURRY , MY MACHINE IS FRYING .
