    hey guys i just did a quick heat test rendering a 4k file with premier pro. The temp never got higher than 98 degrees and fan speeds stayed under 2300 rpm.

    Check the video i uploaded:

    I've done some more tests with 4k files and it really doesnt get over 98 degrees.

    Because this was mainly a CPU test, there's no sign of throttling in GPU. Would be interesting to know what happens when both are fully utilized.

    How is the fan speed at evening when it is low RPM (1200)? Can you hear it well in a silent room at evening?

    The fans are normally very quiet, they only seem to kick in when I render 4k videos.

    doesn't this cpu throttle at 100 degrees to prevent meltdown? 98 degrees is quite hot.

    Hello all,

    I just used my i5/M395X machine for 11 hours straight with 100 % CPU and 100 % GPU usage.
    I have some logs (GPU-Z and Afterburner) for you in my Dropbox, and it's really telling.

    The CPU temperature reaches 100 degrees Celsius one time and the GPU never goes beyond 94 degrees Celsius.

    So much for the "overheating troubles" many folks are shouting around.

    I edited a short 3 min video again and the cpu got up to 100 degrees, have to test if the cpu speed goes down due to this.

    What were you using? And was it during actual encoding or while you were just editing the chip? Did the fans kick in? Thanks

    During the editing and playing back at full the fans kicked in and the temp was around 94 and it took me about 15-20 mins to edit and then encoding took about 8 mins and during that the cpu touched 100 many times and stayed around 95-99 with fans going crazy. I think this machine would not be good for editing large 4K files. And my video had only 60mb bit rate imagine if it was 100mb then how would this computer handle that.

    Sorry - in lay terms is this operating without overheating?
