    I investigated now the manuals of other Lenovo laptops (y50 and Ideapad 700) and realized, that the depicted sketch/outlines of the laptop are very close to reality, which means: there is indeed a bigger and a smaller fan in the Ideapad 720.

    In comparison to that both fans of the Lenovo 700 and Y50 were or could have been similar in size. Although they look different in size (because of the different enclosures), the actual diameters of both fan engines seem identical. If the engines are identical, the engine noise would be identical. It's definitely different in the Ideapad 720, which clearly shows a different diameter in the second fan engine. A different engine means different engine noise. I kinda expect something like this (photo) - that small black fan next to the standard sized fan... which s#cks...

    I wished the N580 was not that expensive here (in german speaking countries)... the cheapest available version here starts with 1.400€ (TN only), which is the i7/16gb version. They just don't sell the i5/8gb version, which would be ~1000€ (prices from Netherlands, Belgium, Poland). In comparison to that, the Lenovo Ideapad 720 only costs 800€...o_O
    So currently it's like paying +600€ more for the Asus, which is ridiculous. I hope Asus comes to their senses and offers the cheaper version. That additional price tag is just too much...

    Wait 1400 euros? That's the price of the ZenBook Pro UX550. Can you get that instead? Or the last gen UX501VW

    The UX550 is in a range between 1.600-1.800€. The UX501 still costs 1.300€ (and has worse hardware). Also a disadvantage of the Zenbook is, that it has no ethernet port. I often need one (and hate dongles). Regardless, the Asus laptops look like overpriced jokes at this point. I guess I have to wait for "better times" or bite into the sour apple (either high price for Asus or possibly annoying fans for the Lenovo)...

    1300 for the 501 is fine, it launched at 1600 IIRC. 1600 for the 550 is also normal pricing.

    I get the need for a port but the good part is that the Wi-Fi adapters in these machines is actually surprisingly good.

    As for the 6700HQ - it's 10% behind the 7700HQ and the 960M is about 30% behind the 1050. It's definitely usable.

    I had the version of the Ideapad 720 with dual core for a short period of time (a day) so I can give you some feedback on it.
    The build quality is not bad, altough it has prominent drawback with sharp edges, not only on a palm rest but even at the bottom (it seems that the notebook is made up of two metal parts and their connection is not so polished as it could be). Fans didn't seem to be annoying (but I don't know if I could hear the issue you might have with them) and they are not active all the time (small tasks like youtube video doesn't seem to be a bother to activate them, altough they were barely hearable during installation process).
    The reasason why I sent it back was due to backlight bleed in the upper part of the screen. It didn't seem to be due to screen itself but the hard plastic that is around it putted some heavy pressure on it in one place (putting some pressure from the behind released the tension and the bleeding dissapeared). I believe that it was just mine faulty unit.

    If you want to know more about the notebook, I was able to find one review of it, albeit in bulgarian. But you can google translate it.

    Thanks, every information is welcome :)

    I must let off some steam here btw...WARNING... wall of /rant incoming:

    Tbh the only thing which really turns me off this laptop is the AMD Radeon Graphics. I have still a Radeon GPU in my current laptop (and also had before), but due to the enormous heat and sucky driver support I have sworn to myself to never buy a laptop with Radeon again.

    Nevertheless I'm impressed with AMD as they are able to compete with Nvidia in mobile gpus again. Again after so many years... the last couple of years the mobile mainstream Radeons were much worse than anything from Nvidia. The last time I remember Radeon being able to compete with Nvidia was when I bought my laptop 6-8 years ago. Back at that time I also had the choice between Ati/Radeon and Nvidia, but chose Radeon. Now I'm almost in the same situation. I'm seeing "oh, Radeon has become strong again... will I take it?", and funnily enough there is a risk of making the same mistake again...

    What mistake?
    - The heat. Radeons are producing and "radiating" enormous heat ... even now when I look benchmarks and see the temperature between mainstrem Nvidia vs Radeon, there is 10°C difference on average. I doubt it will be much different on laptops.
    - If you ever install Linux and use 3d, you will hate everything Radeon. It was this way in the past, and it is still now. Although I thought this has changed meanwhile (somewhere in the last years I have read how AMD and Vulkan will step up and it will own in Linux) - it hasn't happened that much. I've recently read on the Phoronix website about the RX460/560 experience... and it was deterring. The performance is still so much worse than Nvidia...
    - Video rendering support? Nvidia CUDA is the way to go.
    - Gaming? Nvidia seems to offer smoother and more stable framerates, even if lower fps.
    - Driver support in Windows? Now here is a funny story... It's the same shjt as 8 years ago: go to the AMD website and look for RX560 notebookdrivers. There's a menu where you can select "Notebook drivers"... but there is no RX460/560 model listed. Instead the RX is only listed on "Desktop drivers". The real joke is, that it was the same many years ago! AMD offered no notebook drivers on their website. Instead you were stuck with the one single driver installed by the notebook manufacturer. Back at that time I was forced to use "hacked" Radeon desktop drivers to use the updated driver on the notebook. It's like history repeats itself... Seriously, it makes me mad. If the RX460/560 is already neglected at this point and in such an obvious way, I expect nothing but issues, and being stuck forever with driver errors from the first and only driver release.

    But when you go to Nvidia... there it is: neatly listed drivers for both desktop and notebook GPUs, even the newest mobile chips like the MX150, including multiple driver versions for selection... as it should be.

    It's sad, because I like the Ideapad model. If it had a Geforce 1050 I'd buy it in an instant. But Lenovo obviously thought that Ideapad users shouldn't get an Nvidia, and only the Yoga should get one... wtf

    /rant end :bigconfused:

    May I offer an offset to your concerns with my own experience? :)

    I've owned an 860M, 970M and prior to that, a desktop R9 280. Now, the desktop drivers I won't be discussing too much but those have never caused me any headaches aside from one single unstable driver several years ago. (The desktop is still in somewhat active use)

    As for the laptop drivers - get ready, this will be fun.

    So where do I begin? Well, my 860M machine (a older Y50) totally crapped itself on an OS level - about a month after first install. Reason? GeForceExperience messed with the NTFS system registry and tried to do some weird ****. Any driver beside the one on the Lenovo's site would produce issues of varying severity from simple artifacting in Blizzard games to VRAM leaks and other. There were also, at one point, several drivers that would literally kill the laptop display outright (I think it was mainly on Dell machines without Optimus where the dGPU controls the screen directly). I kid you not. My 970M has been stable so far but ONLY when GeForce Experience and all the other bloatware (yes, it's practically useless) is removed. I also dare not update drivers frequently because, well, lets just say I don't want to lose my University thesis in case the driver decides it doesn't like system32.exe again.

    As for heat - previous AMD mobile GPUs were worse (mainly talking about 6000 series and the R9 200 mobile stuff - the 5000 and 7000 mobile series were in line with Kepler at the time)

    Linux - yeah, that's really a place where Nvidia drivers require less tuning but I don't really know much about the OS to offer a proper opinion.

    Video editing - depends on the software. Adobe loves CUDA, Sony Vegas and Final Cut love OpenCL. I'm serios. testing 2 reasonably equal cards from both OEMs in Sony Vegas makes Nvidia GPUs seem...oddly slow. Image taken from Anandtech

    As for gaming - that depends on the game engine mostly. I've had inconsistent behaviour in CS:GO on my 970M laptop but the 280 desktop (it has a Haswell i5 - should not be too different from the 6700HQ) doesn't fluctuate as much. Haven't tested other games since I do play more CS or at least did until recently.
