    So my 10 month old MacbookPro is driving me nuts, Apple tells me it's quite normal for the fan to start spinning the way it does. I took it to their store and they weren't concerned by the noise, of course in a busy store you can hardly hear the fan but in a quiet room it's infuriating. The moment I open Photoshop CC the fan starts to speed up, within seconds it's so annoying I cannot concentrate on editing.
    I've read online that there is software to force a fan to slow down, but there's a warning that this might cause damage.
    Can anyone offer a suggestion other than ditching the computer.

    Many thanks in advance.

    Maybe you're just a little sensitive :D
    The fan should be totally inaudible during non cpu-intensive usage (web, copying files, using Pages).
    It's okay for them speed up when doing photo editing, but if it's like they reach max RPM within ten seconds and stay there, then yeah, something's wrong.

    Get a fan monitor like Macs Fan Control or SmcFanControl and report your temps + RPM when idle and when it's annoying for you.

    Also check your CPU usage in Activity Monitor - when the machine is idle it shouldn't be higher than 1-3% (with occasional spikes) . If it is, there is something other running and burning through cpu cycles.

    You need to check the temps before you start playing with fan speeds

    The activity monitor shows CPU speeds are much higher. The attached screen grab shows Firefox at 14%, at the moment I took that screen grab Firefox and Activity Monitor were the only programs running.
    I'll check out fan controllers thanks.

    It's more important to check in when you are running Photoshop and doing your regular image workflow.

    Also, which computer. 15" units with a dGPU generate a lot of heat because the CPU and dGPU are running hard.

    - Those figures aren't comparable. Toutou was referring to 1-3 % total CPU use. The 14 % you are seeing is 14 % of one CPU thread. A 13" has 4 threads, and a 15" has 8 threads. So that 14 % translates to roughly 1.5-3 % total utilisation.

    Your screenshot is entirely normal.

    Totally this — the dGPU is major source of heat, even idling. When it's powered on, the temps go up a lot.

    I agree.

    If you're utilizing the CPU and/or GPU, they're going to create heat. The fan spins up to move the air to remove the heat.

    If you want a silent computer, the retina MacBook is fanless.

    I imagine it could handle ~50MB RAW files that your camera produces.

    Or you could spend a little more time troubleshooting the problem your having. In the screenshot you posted about a week ago, was the fan making a lot of noise under that load?

    How loud does it get? Maybe there's a mechanical error and it's not spinning correctly or there's something in there causing noise.

    Do you guys think the weaker base gpu in the new macbook pros will run quieter than the stronger ones?

    I cant stand fan noise, but the 13" 2015 macbook pro sorted most of that. It is silent for most things apart from gaming, previous macbooks Ive had the fans kicked up even for video, which made it very annoying.
