    For all the MacBook Pro with Touchbar, my 15" has ALWAYS the fan on, even if in the lowest speed. I can barely hear it, but is always on. Is it normal?

    The fan will always be on, as it needs to constantly cool the computer. Get a utility like iStat Menus and you can see what the speed of the fan is. That way you can see if its an issue or not.

    Still it is a little annoying. The 13'' stops the fan completely and the 12'' doesn't even have a fan.

    In a quiet room it is definitely audible.

    Interesting. I have the 2016 MacBook Pro and have yet to hear the fan come on one time; unless it's so quiet I cannot discern the sound. I have had it get very warm once or twice though.

    It's just to get used to it. I'm coming from a Macbook (12") that is completely silent and a rMBP that for light browsing was silent while with light gaming or something a bit more intensive was super noisy.
    So now, with a macbook almost silent even with something intense, is a good thing.

    quick question, i have the 15in and i use macsfancontrol because i would rather have a cooler machine than a quiet machine. is it bad for the fans to run at max for extended periods of time?

    Fans on the 15 inch TBMBP are always on but that fans are so quiet that it's hard to tell. Press your ear to the keyboard and you'll hear it whirring away, even if idle.

    is it safe to run them at max while gaming?

    Probably not bad other than maybe they'll get louder with more bearing wear over (a long) time, but totally unnecessary to do what you're doing. Just let the computer handle this by itself, there is absolutely no benefit to cranking the fans up manually all the time.

    100% yes. Don't run them at max with light/regular tasks though.

    Right. I don't run them at max 100% of the time. But I do use macsfancontrol to have them ramp up sooner to keep my system cooler rather that let it get really hot first to keep it quiet

    Had the same issue with my Touchbar MacBook 15. Did a restore and an internet restore, fan stayed on the entire time.

    Took it to the Apple store, bad sensor, logic board needs to be replaced. It should not be running all of the time.

    I'm kinda confused now. Was under the impression, that fan should be always on on the 15" tbMPB.

    It *is* quiet. Unless you're using the machine in a particularly quiet environment, you won't probably hear them without actually bringing your ears unnaturally close to air vents. I haven't personally found a place where I could clearly discern that sound. Maybe there would be a chance for it in a traditional cottage middle of nowhere, on a quiet day. Anyway, the sound of using the keyboard will completely overpower that hiss.

    Not possible if Idle is 2160/2000. You can go higher. Not lower.

    Apartment in the middle of the city, windows closed. You can easily hear the fans.

    It's not that it is loud, but it is a clear step backwards from the silent 13'' (idle) or 12'' (always).

    I couldn't really tell the difference between ambient noise (which consists mostly of ventilation and relatively low traffic noise in the distance) and fan noise on this laptop. I feel it's satisfactorily low when idle - especially in comparison with the keyboard.

    I agree. Compared to any other non-Apple laptop I've heard it is still quiet.

    As for the keyboard it's really loud, but after a few days I think I got used to needing less force to actuate keys and it's gotten quieter. Or I'm just imagining stuff...
