Thanks! BTW any similar priced alternatives for the pure base 500 available? With window kit or so? Fucking retailer took more than 3 weeks to deliver it and there isn't even a delivery date. Need a new case >:O

price is ok, nothing to call a real schnäppchen but decent. board will do its job, but nothing more.
look for fractal design define r6, a little "bit" more expansive than the pure base though. its a nice case, i good the non kiddie / non glass version last year

Ehm.. little "bit" more expensive at 129€ vs 54€(incl. shipping! Well ok, it ain't a deal if you never get your item I guess...) ?

Fuck this shit. If I don't turn on the case fans, the CPU fan will run on 100% in idle in windows. WTF is going on? Is there some setting that I can enable so tha this lunatic CPU will not try to randomly overclock to 4.5Ghz when I'm doing NOTHING?!

Use ryzen balanced power setting in windows, do you have latest chipset drivers installed?. Sounds like you have some aggressive temp based fan profile on for CPU in bios. I have personally controlled all my fans with corsair commander, hate bios settings for fans.

@Breezer: Apparently the Ryzen Power Settings are now in the regular balanced power setting. So I chose that one and the system runs much more evenly. Thank you!
Also I replaced one of the fans with a DC controllable one and the difference in noise is very audible.
Now I am no electrical engineer and a noob when it comes to this kind of stuff, but I want to try out something and maybe get an opinion from you guys.
Let's say your typical 120mm fan takes 0.12A at 12V for a total power draw of 1.44W. Let's round it up to 1.5W. Now for whatever ominous reason let's assume that the fan will draw 2.5W additionally at 5V.
I have 4 of these fans and they are connected to a control board which has a 4-Pin Molex connector for power delivery. The fans a total of .5A on 12V and 2A on the 5V rail of the 4-Pin Molex that comes directly from the PSU. And because of this, the fans work at 100% ALL THE FUCKING TIME!
4-Pin Molex:
[O-O-O-O]
12V-ground-ground-5V
My B450 Tomahawk Max has 4 SYS_FAN connectors, all 4-Pin and they can be seperately switched to either DC or PWM. SO I would switch one of them to DC to regulate the voltage of the fans.
Apparently motherboard SYS_FAN connectors are specified up to 1A, but I read that you shouldn't necessarily max these out and rather stay around %75 max usage (basically below .75A).
SYS_FAN
[I-I-I-I]
(up to)12V-ground-Sensor-PWM
This would mean that I can safely attach all 4 Fans to one SYS_FAN and expect it to deliver the desired voltage to regulate the speed and required amps to power the fan, right?
But the ARGB part of the FANs will need to stay on the PSUs 5V rail.
Where do I get the RED outlined cables/parts/connectors? And will this work?

...the smoke effects will probably be very very real? 
If I'm reading your diagram right I don't think it's a very good idea to connect two "different" 12V/5V sources to whatever that PWR thing is

Well I would assume that PWR thing feeds the ARGB part of the fans with pure 5v goodness and delivers 12v to the dc motor in the fans 
And there was apparently one thing that I didn't really account for... Yes, SYS_FAN can deliver up to 1A BUT at 12V! Now I calculated that 4 fans at 0.125A will only need .5A on SYS_FAN, but if I reduce them to 6V, they will draw 1A and that might be just a little bit too much 
I have a friend who has a degree in electrical engineering offered me to build something out of some old fan cables... We'll give it a shot next year
