    Now that people are receiving theirs has anyone tested the high end i7 chip under full load? I'm curious what the temps are and if it can handle it for hours on end for handbrake video encoding?

    The i7 isn’t available until next week but I’m curious if anyone got it early too.

    BTO pre-orders came today. Of all styles. I got my i7 today.

    Idle: Sitting around 47C
    Converting a few random videos in handbrake, CPU usage is at 850%-1100%: Temp seems stable around 59-59.5C

    Update: It's been going for 15 minutes non-stop and we've creeped up to 59.8! This thing is as cool as a cucumber. The air output is significantly higher than on the 2012s and it might be quieter at load as well.

    Update 2: I may have led you all very astray with those obscenely low temps. The app I was monitoring temps with, Fanny, was giving me only the CPU proximity temp, not the core/die temps...

    So, with that being said, at load this baby is getting up to a peak of 100C, though it floats around 92-96 at load. This is using both Mac Fan control and Intel Power Gadget

    Hi, my i7 also came today and has this weird noise resemble an old mechanical drive, here is a video of it:

    No? I can't really hear anything in your video, but mine isn't making any unusual noises.

    sorry for the low quality video, the volume is quite low, but there are some buzzing noise.

    Thanks so much! That's actually much better than I expected!

    It might be coming from the internal speaker, like some sort of interference noise. Try moving it or use a different power outlet, or unplug some devices connected to it?

    Thanks for the reply! did try all that but none have worked. Could it be PSU or SSD?

    Guess that means the i7 has hyper threading?

    Yeah the i7-8700 has hyperthreading still.

    How are Plex Media Server transcodes on the i7? Does it make use of the i7 fully?

    Any thermal throttling after video encoding for long periods of time?

    I didn't notice any throttling after 40 minutes, nor should they be throttling at <60C. These processors should easily handle up to 80C according to the gaming crowd. I think they don't throttle until 100C

    That’s great to hear. I’m also curious what the FPS is like for handbrake when converting h.264 to h.265 1080p Blu-ray rips (if you have any) on like a medium setting. Not using intel quick sync.

    Thanks very much in advance for testing! No worries if you don’t have the time.

    It stays under 60 degrees under heavy load?

    I am sold. Saw RAM upgrade instructions, now this...that’s it. Can’t wait till December.

    I can't believe it stays under 60C full load (i.e. without throttling). I'd wait for further confirmation of this.

    What's the fan noise like at sustained full load?

    I have my i7. This thing runs HOT when in idle, like I would not put my hand on it.

    Yes, same here. The top getting pretty hot even in idle, but I did not feels it gets much hotter when under heavier load. Seems Apple just do not want the fan to run when idle, but I feel it is too hot for me when idle.

    PS:
    By the way, the istat menu helper does not support new Mac mini yet, that there is no sensor readings available yet.

    What’s the cpu temp?

    Hear some buzzing sound like coil whining.

    yeah, I suppose it's the same ssd coil whine issue mbp users have.

    That's unfortunate. Tjunction is 100c though i'm not entirely sure what that is. Perhaps it throttles when it hits that temp?

    Edit - Reading it seems that at tjunction it will throttle the processor. But at tjunction max it will shutdown. I don't know what tjunction max is for this processor.
