Basically I built a new PC, and I'm trying to figure how exactly I should setup the fans. I currently have a 3700x housed in a Lian Li Dynamic PC-O11, cooled by a h150i pro and 6 intake fans on the side and bottom.

I understand the new Ryzen runs hot as I'm getting idles of 30-50c and maximum of 85c on prime. Although it's gone up to 94c AIDA64, averaged around 82-83c. Anyway I feel the setup is fine, or correct me obviously but I'm struggling with the noise of the fans despite altering their speed. Basically slightest increase on the temp puts one of the fans on sudden full speed. What I've done is basically populated all the fan headers on the motherboard. Is there a better way to do this where they are all working in conjunction and if somebody has advise in setting these up.

For further information: motherboard is the x570 aorus pro and fans are ml120

ML120 RGB lists current as 0.219A peak. So you should be able to run 3-4 off of one fan header using splitters.

Alternatively you could get a bigger splitter such as an XSPC 8-way:

This will take a single control signal and distribute it to 8+ fans.

That said, I'd look at why your temps are poor. Is the case well ventilated? Does warm air build up inside it? Feel the panels and roof.

Is the thermal paste application good? Is the cooler mounting and pressure ok? Try a repaste and remount.

How are the temperatures from core to core? Maybe the cold plate isn't suitable for Ryzen 3000?
 
Ambient temp is fine but maybe thermal paste application is incorrect. I simply used the pea method. Also for the hub it only controls one fan right??
 
Got the hub and running everything via single fan speed. Resitted the cooler, now I'm getting roughly 78-83 with stability test on aida64. Is this a more reasonable temp for the h150i pro?

I think I've figured it out, if I'm doing benchmark for CPU only it maxes around 63c. When I do the full stability test it goes all the way to 80c
