    media composer making fans noisy

    I have recently puchased a new imac 2017 i7, 24 gigs of ram. Latest media composer makes the fans run really loudly about 2 minutes into a simple three minute sequence!! Arrgg! This was supposed to be dream machine !

    Ant thoughts?

    Re: media composer making fans noisy

    I am thinking of purchasing the same machine, and I've noted lots of comments on the mac forums (macrumour eg) about the fans. What kind of media are you playing back? MP4 uses a lot of CPU (dnx does not) does this impact the fans? Take a look at the CPU page in the activity monitor (in utilities Mac OS) and see how much the CPU is working (there is no measure of gpu in activity monitor)

    i am keen to follow how you go with this machine, it's this or a hackintosh for me!

    This blog is really informative on how to use the video cache and general hardware resources;

    There is a discussion thread for the blog on the forum.

    I'll try and keep you up to date. The thing I have found is if I play the same sequence in the source monitor, the computer has no issues and behaves the way I thought it would. I have no issues with the performance of the machine, its nice and snappy and the interface looks great on the screen. But the fans on record monitor playback is deeply frustrating. The cpu hits 250% and the fans cycle up and down every thirty seconds or so. Its only running DNX 36. I have run much more complicated sequences on an imac much smaller and older.....

    Hi Mark I wonder if you have achieved a quieter edit space? Or are you still editing in the wind?

    is it related to your experience?

    Re: media composer making fans noisy

    So my new machine generally runs fairly quiet.  The fans will speed up for intensive tasks like playing back h264 or transcoding, but otherwise it is a quiet machine.

    Re: media composer making fans noisy

    That good to hear. I had no luck with my machine. It went back to Apple to see if anything was wrong, they said all was well, of course. Plugged it back in my cutting room and same issues. In the end I gave up on it, had a huge argument with Apple who refused to give me my money back as it was passed the grace period. In the end the Apple shop I dealt with honoured the deal, and I swapped it for the mid-range I5, with lots of ram. NO ISSUES. Quiet as a mouse, the fans NEVER spin up that I can hear anyway. It may have been a dodgy unit, but from what I have read online, it seems to me the I7 just runs really hot, so the fans are going to be up and running all the time. I couldnt live with that, as a drama editor. As far as editing is concerned I can feel no difference in performance, I don't need to transcode a great deal, so the 20% less speed is something I can live with after all the time I have already wasted. I am a happy chappie now. If all is working then I am happy for you!

    Re: media composer making fans noisy

    Thanks for reporting back, and good to hear you are sorted. I’m sure an i5 is good.

    I’ve had one day on mine when the fans were up running fast, even when I was barely using the cpu, I relaunched the avid and it sorted itself, (when the fans were running I looked at the activity monitor and there was a huge amount of system cpu activity, after the relaunch there was hardly any system activity, even though I was doing the same edit task).

    So my conclusion is the avid simply got mixed up, and was making a system call that was unnecessary.

    enjoy your quiet edit, Martin
