Other than that you can upgrade the blade SSD Sostituzione SSD MacBook Pro 15" Retina Display versione metà 2015.
As far as cleaning and applying fresh thermal paste I would hold off doing that. Instead I would first monitor the systems temps using a app like TG Pro to see where things are with what you are doing. Then after awhile then review if its needed or not. I often find people are too eager and if there haven’t done it before end up messing up the logic board and besides the heat sink maybe bad Vs the need to refresh the paste. You’ll want the full version to gain the logging.
