    I’ve got the trick

    When the latop stress tested on a table, it’s 85C CPU 78C GPU When I lift the far edge by 5cm (put a book) it’s 81C CPU 73C GPU, 5C drop!

    Really laptop suffers so much from the lack of fresh air intake, not only it makes awful whistling air sound but also the temps increased by 5C

    Acer low qualified engineers must be fired without any farewell bonuses they did such a poor job, why they just didn’t put a huge grill on the half of bottom like does lenovo or msi

    Just a such unforgiving stupid mistake

    well obviously you will have worse cooling possibilities 

    but another issue is still there and it is related with the poor case design near the cpu fan (initially plastic one) because this one is inverted one so it gets most of the air from inside of case and due to some interference on the side where the case cover
    it makes it to produce awful sound with air whistling and you can easily indentify it if you cover vent grid above cpu fan by a hand, only then laptop will be quiet as it must be and as most of other laptops with proper made design do
    Belik do you think it would be possible to find a replacement for the "inverted' fan, one that is in a normal position to remove all the weird sound it makes, or a way to mod-tweak the already existing fan and place it in the way it was meant, not inverted.

    Also, when making my own fan curve in NBFC, I'm setting it up according to the CPU temperatures, and according to that the GPU fans spin too. Is it possible to "separate" the two fans and kinda make a curve only for the CPU fans and another one for the GPU because this way the GPU fans are always spinning faster + lounder for no reason (Let's say I wanna put the CPU fans to 1500 RPM and the GPU fans automatically go 2000 RPM, which is not needed at that point). Just trying to clear that out. Thanks
    It may work, I’m going to use fans from Lenovo and orient it properly Their fans a head better than delta scum by Acer

    Nbfc is not a solution coz each poll to EC generate huge latency spikes

    Yeah the latency is quite bad but I've been using NBFC in spite of that. I ordered a plastic fan to replace the aeroblade on the gpu and then I might stay away from the NBFC in case that reduces the GPU fan volume, otherwise having the GPU fan run at like 2500RPM almost all the time is way too loud, combined with it's buzzing. 
    If and when you get the lenovo fan installed in your laptop, could you share the model of the fans and how is the system performing in general.

    I wanted to ask whether you installed the Lenovo fan in place of the inverted CPU fan and if so, does it work properly?
    Thanks.
