I just upgraded from a 2014, 13 inch, 16 Gig ram i5 to a 2017 15 inch, 16 gig ram, i7.
I never heard the fan on my 13 inch I had it checked because I thought it might have been broke.
On this machine the fan hasn't stopped. Is this how this laptop is or is it just because I just put my stuff on it and it needs a minute to put everything where and how it should be?

They spin all the time on 15 inch at around 2k rpm. I had the 2017 15 and heard them in a quiet room, too. Slightly annoying when coming from a 13 inch, which has them either off or be running at 1300 rpm and being silent.

Get istat menus or something else that shows rpm. If it's at 2k, then it's the "idle" noise.

Use Activity Monitor (in Utilities) to see if some process is requiring CPU cycles. Spotlight indexing, especially when new, can require cpu cycles, which can require the fan.

Does it still continue even after a reboot? I had one unit that would do something similar. Temps would shoot up to 95-100c and wouldn't stop until it was rebooted. It seemed to do it randomly with no rhyme or reason, but when it did happen, rebooting was the only solution. If that is the case, you might want to exchange the machine. I haven't had the issue repeat with the current one.

The fans on 15" always spin at least 2000 rpm. If it's spinning above this at idle, after machine has had a day to index everything etc, then there may be an issue.

The fan stayed on the first day. Haven't heard it since. Im guessing it was because I loaded all my stuff on it
