Good Night 
My name is Fran and i'm seeking help with a problem I've been struggling to solve by myself for 2 Weeks already but i couldn't
Recently i installed a Pair of 6 Fans to my Chasis
0 Problems with the Installation, but when I started using them the hell began
They used to go really fast for a second and go back to normal, and after that they began to randomly slow down for some reason, and they go back to normal after a second which is really annoying, this happens always even when in idle, and it's very uncomfortable and as I said, annoying
My M/B It's a A520M-H 
My CPU It's a Ryzen 5 3600
My GPU It's a GTX 1600 Super

What make / model fans are they? Are they 4 pin PWM fans?

This may normal behavior for PWM fans, or normal motherboard behavior adjusting the fan curve to the load it is under. Generally you can adjust fan curves in the UEFI BIOS somewhere... 

If the fans ramping up and down disturb you, use a software controlled fan controller such as the Corsair Commander series and adjust the fans to your liking given the load your computer goes through....

What fans? What headers are they plugged into?

Does that mean 12 fans?

No, i'm sorry, 6 fans in total, they're 6 fans in total 
They're 4 Pin PWM Fans
They're connected to the SYS_FAN 1
They're a Chinese brand, they work really fine i mean no troubles with the air-flow
The only problem is that slow down they do for a moment
(I know it will sound dumb but, sorry for my bad english, im from South america hahaha)

I've been trying to use GIGABYTE CONTROL CENTER For fan management, which adjust the fan curve but the problem still appears, they still slow down for a moment and they go back quickly

6 4 Pin PWM Fans, Attached to SYS_FAN 1
(I should mention they're connected to a Fan Hub)

Have you tried changing the fan curve for the sys_fan1 header?

I did, but eventually i end up with the same problem
Im not sure if it's the fact that is a Gigabyte M/B, or the fans, im not really sure
If you want i can send the link of the fans 
Like i said, sometimes they get fast and other times slow, it's really weird
But mostly slow

How often per minute/hour does it alternate? Does it correspond to what you're doing or is it always the same? What fans do you have? How long do they spin down for before returning to normal?

 

Try plugging them directly to motherboard headers and

Set the curves. What happens? If it is corrected, the hub is the problem.  Ask for a replacement. 

I've been using computers since around 1978, started learning programming in 1980 on Apple IIs, started learning about hardware in 1990, ran a BBS from 1990-95, built my first Windows PC around 2000, taught myself malware removal starting in 2005 (also learned on Bleeping Computer), learned web dev starting in 2017, and I think I can fill a thimble with all that knowledge. 😉 I'm not an expert, which is why I keep investigating the answers that others give to try and improve my knowledge, so feel free to double-check the advice I give.

It's random, i tried counting the time between that happening but it's definitely random, and it's always the same except for something, sometimes speed ups, sometimes slows down, and they spin probably for a second, i've been thinking abouut the probability of the hub but, im not sure if that's the problem.

is it possible the fans are coming to a stop? i had an issue with my old NZXT fan controller having too many fans per port. It couldnt provide enough current for like 4 fans plugged into one port at a low speed, so it would stall, and the controller would spin them up to 100% to get them going again, then theyd slowly slow down and stall, and repeat.

It's probably that! Your problem kinda sounds like mine after all, lemme try recounting all to clearify but, sounds really similar to what's happening to me
1) Installed the fans no problem with that
2) In some moment they started to get at 100% And back to normal
3) First problem stopped happening but now they either get fast for a moment or slow for a moment
Considering the fact that the Fan Hub is 100% Chinese (Thank you Aliexpress) It's a posibility! I'll try checking some of the tips given in the post before
But your problem it's actually really similar to mine!

A photo of the hub by the way, maybe it's useful for something

Which temp sensor is the fan rpm responding to? What fan curve are you using?

Have you tried monitoring temps when the fan speeds are ramping up and down?

Does the fan hub have a sata/molex power cable, or is the motherboard powering them all? Does that hub also have ports for RGB?

Like I said to the OP, plug all the fans to the headers and don't use the hub. That would show if what they're describing is from the hub... right?

 

Also, please answer my other questions, which were better stated by @WoodenMarker.

SYS_FAN 1
And yes i tried but i can't keep track of it, happens so fast i can't see it
Right now im trying using Fan Control, this is my curveimage.png.ae9f213331566939ef9d69ab1976cce3.png

Just wondering, why have all those points with about 1% of variation between each, just delete all points and have a flat line up to 80C? And by all means, if it works for you dont listen to me 😅 Just wondering if it makes a difference to you or if it would be easier to manage with less points

 

Also what is your step up and step down %s for your fans on Fan Control?

It wont help with the ramping up and down too much but if you lower the step down percentage by another 1 or 2 it will ramp down slower, both slowing the noise and pitch change and allowing it to cool at a higher RPM for a little longer, other that that and the fan hub stuff im not too sure

If you're using @Rem0o's software, your best bet is to ask them.

1146rpm at 40% is pretty high rpm and is at the bottom of the curve.

Have you figured out what noise level you're okay with? The fan curve should top out at a speed that isn't too loud for you.

 

What temp sensor is the fan curve based off of?

@WoodenMarker you pose a good point, @Frankykujo Whats the max RPM of this fan? Its not 3000RPM is it? The maths says so but unless your using noctuas 3000RPM server fans or something similar thats kind of insanely high for a normal system fan 😅

Come to think about it the max RPM Of this fan is 1800! I never knew there were 3000 RPM Fans, that's a lot of power!
