Hello,
I have a "Macbook Pro 15-Inch Mid-2012 Retina" Model.
It's lagging due to CPU throttling under "heavier loads"(evident by very high kernel_task cpu usage in activity monitor, and high temp to the touch and monitored on SMC fan control).
The only way I can get around this is essentially using the computer for music and web browsing. Anything beyond that doesn't work well unless cooled by an icepack, or perhaps being in a cold environment.
I'd like to fix this, because before this issue started, this computer worked fine for me, and there would be a lot of money lost with minimal utility gained by upgrading to a newer macbook pro, aside from that I can't really afford one anyways.
I've tried a clean install, resetting the SMC and NPRAM, trying to blow some dust out from the outside, but nothing has helped.
At this point, it seems like I will need to open it up, try to remove dust from the fan systems with a air blower + clean the CPU & GPU, re-applying thermal paste on both.
I've never done anything quite this hands on before, (experience limited to GPU/RAM/HD stuff in iMacs/MacPros) but I'm confident I can do it. That being said, I will need to order some parts and commit to risking breaking my laptop, so I'm just looking to get some insight or advice before I do so.
Has anyone had an overheating issue like this on their macbooks pros, and managed to fix it? Is cleaning dust + reapplication of thermal paste likely to fix my laptops issues or is it likely to be something else?
Any other insight into my situation?
Cheers!
