High temperature after 3 years of use
It's not a mystery that large amounts of dust are being accumulated inside the fan, the heat sink and the rear vent.
That said, I want to point out that now my MacBook is working at 65-70ºC with the fan at +4000 RPM with normal use (iTunes, internet, Mail or Microsoft Office), until 1 year ago it usually was at 50-55ºC @ 2000-2800 RPM. with normal use, I can't even just play a game or encode a video, it goes up to 97ºC with the fan at 6000rpm and it freezes, from being working at 70ºC @4000RPM one year ago.
Is this just dust or is something else happening here? How am I supposed to know? I ask because if it's worth it to open the laptop, take out the heat sink and etc. I really don't know how to clean it all up...
Thanks in advance!
Is this a good question?
