Hi,
If you check the notebook reviews, all of the laptops currently are in the same category. They are loud on high performance, no workaround. Whoever says other brands are better, thats a lie.
In fact, if you see the reviews, other laptops like dell's alienware even gets hot also, not just loud. And they cost more.
I bought yesterday a GL503VS, it is certainly loud, I will try to do something about it as well, but it was not even getting warm! The GPU were below 80C with performance settings on fan speed.
The quality of this particular laptop is VERY good, and the screen looks awesome (putting aside of the TERRIBLE Backlight bleed that is atrocious to be honest, I don't understand how Asus and all other brands wont push the IPS market to fix this damned issue).
I was thinking about buying HP omen for similar (even cheaper) price than this laptop, however for that laptop the screen kind of crap, low brightness, worse quality IPS, and a LOT of heating, for similar loudness.
I'm telling you, stick to your Asus, you get good service, replacement in case you get issues later.
I agree, not perfect and I blame all the brands out there, the Max-Q design should be completely standard now, mid-range budget should already have that design, yet they still not implementing it on wide range of models but only on high-end machines that cost a fortune.
