Hey Lavachyste,
Congrats on your new mac.
I would advise that you install a fan control app (I bought iStat Menus), and then set your fan speed to a fairly high setting (if you don't mind the noise).
Macs tend to run hot, because Apple likes to keep them fairly silent. The tradeoff in Apple's approach is that your chips will be unduly strained by the rapid heating and cooling caused by the fan throttling.
My Mac's GPU actually died, from what was likely a combination of thermal strain, and a faulty chip design for my computer model (Macbook Pro 2011). I did get my logic board replaced once, but Apple is no longer stocking logic boards for my mac (so just keep that in mind regarding the longevity of your own device).
On the power user side of applications, if you are interested in automating your filing system, I highly recommend taking a look at Hazel (https://www.noodlesoft.com/).
Respectfully,
Sam
