Sharkoon VG5-W case has 3 built-in fans but my selected MOBO supports only 2x4 pin fans. Any advice?

Planning to build a new config, but I have a huge problem:

https://en.sharkoon.com/product//VG5-W#desc this case

and

https://www.asus.com/Motherboards/ROG-STRIX-Z370-G-GAMING/specifications/ this mobo

as far as I can tell not compatible at all.

The Mobo has only 2 4pins fan connectors but the case has already 3 built-int, 120 MM fans. How should I fix that problem? Or simply I should change my case to another one?

Sharkroon uses 0.25A LED fans in their cases. I know it because my AMD build (full specs with pics in my sig) sits in this case from Sharkoon,
specs: https://en.sharkoon.com/product/1678/DG7000-G

While you could run all 3x fans from single MoBo header (3x fans total would be 0.75A), you'd need 3-way fan splitter cable. I'd go with 2-way Y-splitters and plug 2x front fans in one header while the rear fan plugs into 2nd fan header.
Y-splitter at amazon: https://www.amazon.com/Noctua-NA-SYC1-Accessory-4-pin-Y-Cables/dp/B00KG8K5CY

This way, you can control the rear fan speed independently from front fans while both front fans would run in sync. Also, you can connect the 3-pin fan to a MoBo's 4-pin header just fine,

It'll be fine. I have six running off one.

Boring bit: mobo fan headers are usually good for 1 amp. Most case fans (3-pin) use around 0.1 amp, so it's okay to run a bunch off each header.

Though, disregard the above statement that most 3-pin fan are using 0.1A. This isn't true since when fan has LED lights, it does consume more power. On average, non-LED fans consume about 0.2A while LED fans, on average, consume 0.3A. This is so with 3-pin and 4-pin fans. Some 3-pin LED fans can consume even more power, e.g Corsair AF120 LED Quiet Edition which consumes 0.4A.

Most MoBo fan headers are rated for 1A (ampere) at 12V (volts) and can support 2-3 fans per header. However, until you don't overpower the 1A rating of common MoBo fan header, you can hook more fans to single fan header. But you must make sure that you don't exceed the 1A rating. Else-ways, you'll fry the fan header and you can also damage your MoBo further.

Hm what if I choose the VG5-V variant (without side-window) and I mount 2 more extra fans on the sides? Will it be better cooling/overall performance? How should I position them? So if I'M correct even with these extra 2 fans (5 total) the power consumption would be enough.

BTW will I be able to control these fans with the asus smart fan technology if they are connected via Y cable?

That depends on what fans you'll install at the side.
Usually, side fans are used as intake fans to bring extra cool air for the GPU and CPU if CPU has top-down cooler (e.g Intel's stock CPU cooler). But when CPU has tower-type cooler (e.g Arctic Freezer i32) then the side intake fan wouldn't do much good.

As far as connecting all 5x fans, you can connect them to the MoBo if the amperage rating isn't reached or use a fan controller. Since Sharkoon case has 2x 5.25" ODD bays, you can use one of them to install a fan controller in.
I'm using 5.25" fan controllers with my Skylake and Haswell builds and i'm also planning to get one for my AMD build. Depending on a fan controller, you can hook 4 - 6 fans to it and control each fan individually. Some fan controllers also support LED strips (like the Thermaltake Commander F6 RGB which i have in my Skylake build) and many have LED touchscreens (like NZXT Sentry 3 which i have in my Haswell build).

Using Y-splitter doesn't remove the fan control method that you can do from BIOS or any 3rd party software (e.g SpeedFan). Though, do note that all fans connected to the single fan header will run in sync and you can't control them individually.

I was looking after these controllers and found : THIS ( SCYTHE KAZE Q Fan Controller 3.5" ) as a heavy budget-oriented option. Is it any good for my purpose or if it's possible then could you please show me / offer more alternatives in / around this price tag?

Also how exactly these gadgets work? Is there anything specific I should look after or need to pay attention to?

There's also hubs like this: https://www.nzxt.com/products/grid

They're a lot cheaper than dedicated controllers, working via software for best (ie quiet) results. I suspect that mobo will have chassis fan control in it's bios, or perhaps it's own fan control software for windows. There's also speedfan, but there's quite a learning curve that seems to put people off.

NZXT GRID doesn't have any control since it's just the regular fan hub that takes the +12V power from PSU and feeds it to all connected fans. What does have software control is the NZXT GRID+ V2 and GRID+ V3 internal fan controllers,
V2 specs: https://www.nzxt.com/products/grid-plus-v2
V3 specs: https://www.nzxt.com/products/grid-plus-v3

Corsair also offers internal fan controllers like NZXT does. Those are Commander Mini and Commander Pro,
Mini specs: http://www.corsair.com/en-us/corsair-commander-mini
Pro specs: http://www.corsair.com/en-gb/corsair-commander-pro

Since the Scythe Kaze Q is 3.5" fan controller, you'd need a 5.25" to 3.5" adapter frame to mount it in your Sharkoon case. Also, since it doesn't have any display, there's no way of telling at which RPM the fans are spinning.

For a nice budget fan controller, the Thermaltake Commander FT is a good choice,
specs: http://www.thermaltake.com/Cooler/Cooling_Accessory_/Fan_Controllor/C_00002651/Commander_FT_Touchscreen_Fan_Controller/design.htm
pcpp: https://pcpartpicker.com/product/XnnG3C/thermaltake-commander-ft-fan-controller-ac-010-b51nan-a1

I did consider getting either this or NZXT Sentry 3 while in the end, i went with NZXT.

Here's a list of many fan controllers that you can consider if you don't like Thermaltake Commander FT,

There are also plenty of tutorial videos in the net on how to operate a fan controller. Here's few of them,
