I’m running a Early 2013 Macbook Pro Retina 15”. It has already had the old thermal paste taken off and replaced with new paste. I have also opened up the back of the Macbook and sprayed out all of the dust particles I could see with a compressed gas duster. The only possible fix that I could think of at this point is replacing the heatsink, but I came here because I do not know enough to say whether or not that would possibly fix this issue. In addition to running much hotter than any Macbook Pro Retina I have ever seen or owned (which has been at least 5), the fans go on full blast when it hits around 85-90°C. I know this may not be considered running too hot, but the macOS considers it to be so (and I have seen the fans start to kick in around these temperatures on other similar or same Retina models when the computer is putting out a lot of processing power). The odd part about all of this (if it didn’t already seem off) is that it happens almost immediately after starting up my Mac. Ever since I did a complete uninstall and reinstall of the macOS (since I bought it used), it has done this. So I’m sure it’s not a virus issue or anything else along those lines. I do not use this laptop for much more than browsing the net or watching videos, but I would say about 95 percent of the time it’s used to navigate Google Chrome. Any advice or suggestions based on experience or knowledge pertaining to this matter would be greatly appreciated!
Lets get a better idea on what you have for thermals, install this great app! TG Pro with a cold system snap a snapshot of the Apps main window making sure all of the sensors are visible (you may need to adjust the window size so the ones at the bottom are visible in the snapshot). Take a second when you’ve run a hard running program as well post both here for us to see Adding images to an existing question You may also want to run your systems onboard diagnostics.
