    I'll answer these questions for you tomorrow. So far I haven't heard any coil whine. I think the speakers sound similar, but I'll queue up a movie or some music and test it out (both sound pretty terrible fyi).

    I got mine yesterday. I haven't had too much time with it. Just setting up.
    PUBG at stock got between 60-90 fps on the lowest settings, except high textures.
    Ive since found the GPU can take a +200 MHz overclock easily so I'll do some real tests + revisit PUBG later. Additionally the game should benefit if you go dual channel on the memory.
    I also tested Killing Floor 2 at max settings with a +200 OC and was surprised to see it getting triple digits in the fps.
    The machine is a silent as heck but I've got a wimpy 7300 so that was expected. Clocks only hold at 3.1ghz on 4 cores and temps are in the low 60s max. I'm going to fiddle around with Throttlestop more to see what I can do, mainly because the CPU parks itself too much and it's not as snappy as I'd hoped. I think that can be mitigated at the expense of battery - but get to know Throttlestop gents and you can also have a battery profile too if you swing that way.
    The screen unfortunately is a LG so OCing it is a waste of time. I've got a 120hz TN on the way which will hopefully also get rid of Optimus once installed. No backlight bleed on the LG panel, its fine and looks decent enough - just I can't do 60hz.

    For under $1000 it's a pretty decent little unit and it's perfect for what I need. I wish it had a better bezel as I do with most modern laptops.
    The palm rest is excellent and very nice to the touch in aluminum.
    Dell didn't really need to go for max Q 1060 as there is so much overhead. Even with the OC it sits in the low 60s. So I'll just be having it start up every time with the OC and it's probably about as good as a stock laptop 1060.

    The video review shows a noise of 47-48db while gaming. This (or this) was the fan noise from 7567 and should be around that 47-50db range.

    If that's the case it's not so silent... Is your system behaving better?

    Considering the low temps I don't think they're properly configured... Some redditors are also reporting that the fans are not only loud but they also stay on for 10-15 mins after you stopped playing games. No matter if temps are cool again earlier than that.

    Let's hope a bios update improve things. BTW, Max-q was supposed to stay below the 40db level... I'd called it a 1050Ti(2).:D

    Just gave it a fair test in PUBG. Yeah you do definitely hear them. In this example it's the CPU fan. The GPU doesn't really go beyond 60w and basically sits at 60 degrees. The 40db thing is with quiet mode enabled from what I've heard.

    Anyway, the anemic 7300hq BGA can't really cut the mustard in PUBG. For this title the game is CPU limited rather than GPU limited. The machine runs perfectly cool. That's not to say the cooling is anything to brag about though. It's only got about 20w to deal with.

    Strange you can't see the pics - it really tells the story. I can see them from my phone - have a try in a different browser if you can. I'll try and do that once I'm home for you.
    Yeah it can totally handle a 1060. The CPU would be fine with a 7700HQ provided Dell managed to do a decent paste job.
    A part of me wishes I got the 7700HQ only because PUBG hammers the 7300 and it's clearly the bottleneck, but for $300 more with a 1060 Max Q it's not worth it. I'd sooner get a Tornado 5 and be done with it. However, the 7577 handles everything else like a champ. Hopefully PUBG had some CPU optimization coming its way and I'll be super content.

    So here is some temp logs playing witcher 3 on ultra settings (typically around 50-60 fps)...

    First I played it completely stock and it ran great. The fans spun up, but they were anything but really loud, I was still comfortable gaming with the volume at ~25%. The max fan speed was 5400rpm:

    Then I turned on my undervolt (-.165v) and overclocked the GPU by 200mhz on the core and 250mhz on the ram. Max fan speed was 4800rpm:
    Witcher temps undervolt+OC.PNG

    Over all it did great. The highest ambient temp was 74C. The GPU and CPU stayed at max clocks and I had no throttling.

    Here are answers to some of the previous questions in red:

    1) Thunderbolt 3 port it is x2 or x4 pcie lanes?
    2) Name/ID display panel?
