    +1. I really don't need fancy GPU at all, just H CPU quiet, light and big battery (with good fan control). A 17" version of the Elektronics U device with H CPU would be wonderful, lol.

    Fan control on Aero has proved to be a problem for me.

    What I dont understand is that TongFang had fan control on the QC7, but it was removed eventually. And then they release newer Aluminium alloy laptops with fan control. Like wtf. I would be glad to donate to someone if they can mod the control center to have fan control, like some others did on other TongFang laptops.

    You forget Intel had a hand in designing these laptop's and on clear Intel fashion, they like to maintain control and give users the least amount of control on their notebook chips.

    Out of desperation, I had a look at Control center source code. It was obfuscated but C# is relatively easy to de-compile.

    Unfortunately it seems fan modes and manual control are disabled, you can set fans at max, but you can't disable them. You can control led bar, PL values. Anyway that is why https://github.com/lKinderBueno/Rev.Center2-FanManager project is not working properly, even if they use same registry addresses and values as older Tongfang laptops.
    Process / Timeout added by Intel to cool off laptop runs somewhere at embedded controller level and can't be disabled in control center (as far as I can see). Maybe there is registry that controls it, but it is difficult to find without documentation.
    I'm not specialist in EC / ACPI programming :/ if @Prema could give some hints I would be happy to make small open source program to control fans. But I'm afraid if we do Intel will block ability in next BIOS release.

    Intel pretty please, let us control threshold temperature up to at min 60C and cool-off time with some reasonable values.

    It would be easier to make simple Arduino project to control fans instead of digging blindly through EC registries. Via Arduino you can set PWM / RPM below factory spec, even if fan dies on me I'm ok to replaces for few $. Then it would be better run one fan constantly at very slow speeds avoiding on/off cycle every few minutes grrrr, both CPU and GPU share heat pipes so one fan is enough.
    Problem is fans are too loud at minimum spec RPM and Intel runs both of them for what ever reason close to idle temps ... Also they didn't managed to soft start fans, they go 0 to 2600 RPM in instant.

    Shame we can't have open bios, I guess next laptop will be ryzen if performance claims are correct and they don't have any strange problems.

    Or we can end up dumping laptop in something like this, with few holes for quiet 200mm noctua fan, power and thunderbolt cable. At lease when I'm in home-office, quite environment.

    I think Intel should have been more open with the development of this machine. All they needed to do is set the max temp limit that they want and just let us control everything else! If we hit the max temp target they set with my settings I'm fine that it throttles to avoid rma and the like but they should have at least:
    1. Left the GPU temp limit at 87C (id be happy with 82C tbh)
    2. Allowed undervolt in bios
    3. Allowed RAM overclocking through XMP (perma says this is possible through XTU with older bios)
    4. Fully working thunderbolt 3 drivers (I understand this might not always be possible but I've never had as many thunderbolt 3 issues as with this machine)
    5. Fan control (No reason to lock is out when they can just easily set a Max temp target. If I hit the target then throttle me to Oblivion and I'll try better settings!)
    6. Working trackpad
    7. Disable windows hello whole laptop screen is closed and docked to external monitor. This should be common sense.

    Hi

    PSA: For those of you having issues with the trackpad after a while that it starts spazzing out and doing 2 or 3 finger gestures while you only have 1 finger on the trackpad (or it not working altogether). I found a way to mitigate this frustration at the expense of some gestures getting disabled

    Search for touchpad settings in windows
    1. Disable pinch to zoom
    2. Disable 3 finger gestures
    3. Disable 4 finger gestures

    Using the above settings I am now able to use my trackpad after it started spazzing out. I also have the trackpad set to high sensitivity and it doesn't seem to make the issues come back or anything so you can play around with the settings. For anyone who actually uses the gestures I feel bad for you since this laptop's trackpad has been garbage since day 1. I love the performance (only while it DOESN'T throttle) but did I give up a lot of basic working features vs my alienware m15.

    Alienware m15 I lost
    1. 100% working trackpad
    2. Numpad
    3. Build quality (m15 is way better built IMO and the screw don't feel like they will break at any minute)
    4. Stable thunderbolt 3 drivers (I can connect my old m15 to my thunderbolt 3 dock and netflix works on external monitor)
    5. Quiet fans (even on max) with fan control

    The only things I gained from switching to mag 15
    1. Lighter weight (very appreciated)
    2. Mechanical keyboard (I enjoy it but not everyone's cup of tea, it DOES feel cheap for a keyboard)
    3. Per key lighting (gimmick but I am eagerly awaiting project aurora support)
    4. Windows hello IR cam (works as one would expect)
    5. More GPU (electroboost) and CPU performance (but they throttle anyways so it kinda cancels out! maybe max q 2080 from other companies with 87C limit are better despite the $400 permium, some of them can even be bought used in mint condition online for way cheaper or AT $1800)
    6. Really good display (I won't lie, no ghosting or flicker is nice on this display and it gets dimmer than other laptops)

    As nice as this laptop is, if I can't find a solution to this throttle and more of these hardware "failures" like the touchpad start showing up I might sell this for a loss and move to another company. Maybe I'll wait for AMD ryzen CPU's as they have integrated vega igpu that supports FREESYNC and can be paired with Nvidia gpus.... even if it's only up to a 2060 max P (maybe they'll release a 2060 with electroboost someday which would be worth it over this intel GARBAGE igpu and bios that seems to do more harm than good).

    Sorry for the rant but as you can tell, I love what I thought I was getting with this laptop (understanding I'd get way less support than dell) and in the end it seems like now we can't even change the GPU thermal limit to 87C in the latest bios.

    My review on this laptop is done with BIOS 0058 and I can confirm that Asus GPU Tweak II still works.

    i don't get it, they allowed for gpu temp limit tweak, why they got it back with some bios update? Can we revert bios so asus gpu tweak will work?

    Has anyone started experiencing the random wake issues again while the laptop lid is closed? Any fix?

    Ah, how do you downgrade a BIOS? I've not upgraded my BIOS because (a) "if it ain't broke.... (b) I don't know how to rollback if the updated BIOS introduces issues I didn't have before.
