Are you using an older model that hasn't been cleaned in a while? I use an early 2013 15" MBP and the only time I ever hear the fans is when I'm doing compilation with 8 threads (100% CPU usage on all four cores).

I've got a 2015 15" mbpr, and it doesn't take much for the fans to reach noisy speeds. one core pegged will do it after a few seconds. I run into this a lot with the new docker daemon. edit: just timed it (yes > /dev/null), it takes about 60 seconds of one core pegged to ramp up the fan to audible. And I'm used to silent so audible is noisy to me. Two cores pegged gets loud.

  Honestly it sounds like you may want to get your fans checked out. Or perhaps you work in a totally silent environment? Loud is of course subjective, but my rMBP has the quietest laptop fans I've ever used.

    Oh, by far this is the quietest laptop I've used. Most of the time. If I'm playing a game or docker pegs a cpu, that changes. It may still be better than other laptops, I don't know anymore, but once the fans get about 3k they start to get pretty loud. Below that I don't really hear them.

  I'll echo you that my 2015 15" mbpr really screams the majority of the time. I probably should do a fresh install with the latest OS but moving files around is such a pain. Maybe we are in quiet environments and notice them more than other people?

    If there's an app causing it then the "Energy" tab in Activity Monitor should show you which one. Google and Adobe apps along with their helper services are particularly poorly behaved even when "idle".

    Here's my anecdote. The fans on my MacbookPro12,1 spin up to annoying levels if I even watch a YouTube video.

I have a 2011 model that I swapped an SSD into a few months back. I cleaned it out at that time as well. The fan's so damn noisy that the OTHER person on Skype can't hear me. The fans are on probably about 70% of the time I'm using the machine, and often I have to just start shutting down programs at random when I'm done until the fan stops, or else it will run like that for hours. Activity Monitor is particularly bad for CPU usage.
