Which rgb fans are silent?

No fan is silent at full speed. That's the crux here.

You can, however, lower a non-PWM fan's speed with voltage control if your motherboard/fan controller supports it; ableit they won't be able to go as low in speed as a PWM fan. This could be a way to lower your current sound levels without replacing fans.
 
So for context i have currently
These fans

EZDIY-FAB RGB Dual Ring 120mm Case Fans,5V Motherboard Sync,Speed Adjustable,RGB Sync Fan with Fan Hub X and Remote-3 Pack​


I will check the bios again but im pretty sure that these fans are not controllable speed wise except using the remote controller provided.
 
I think it's likely you are just running them too fast. All fans are quite noisy above 1000rpm. Do you really need them to go that fast?

What are they installed in? Are they in push mode? In pull, all fans are much louder.
So what do u mean by push or pull mode?
Is that referring to which way the fans are facing?

They all face the good way lol
So that the rgb lights look best

The fans' speeds can be controlled via PWM or via voltage. Any fan will rotate slower with less voltage applied. It's more so whether your motherboard supports that functionality.

Edit: just popped into my head: you can get voltage reducers that go from 12V to 5V. Still cheaper than buying new fans.

So ive seen the voltage thing in the bios before but these fans I have do not plug into the motherboard directly. I need to revisit the bios again to confirm

What kinda voltage reducers? How will they benefit me?

Yes, which way they are facing. The back is where the label is and the struts that support the motor. Fans move air from the front to the back. Depending which way round they are, they are pushing air through a radiator or filter, or pulling. When they are pulling air through, then the thing they are pulling it through should not be close to the fan, or the fan makes a lot more noise. Noctua make a spacer for pull mode fans to reduce their noise.

Anyway, I guess all you need in this is to tweak the fan curve in the BIOS or buy some reducers for the fans. Noctua make some (Noctua NA-SRC7). A pack of three for around £8. Or you could buy a manual fan controller. Or in the extreme you could buy a software controlled fan controller. All of these solutions are cheaper than buying new fans.

so the bios is only picking up the speed of the CPU fan and it looks like the 3 x RGB fans are uncontrollable for sure even in DC mode.

now tell me about these reducers how will they help?.. I also don't believe they will work on my current fan setup - still not the end of the world I might wait for a SSD or NVME drive to come down in price and open the PC case with new RGB fans then no rush

The CPU fan is going to be a 4-pin connector which has a PWM pin. PWM is required to report fan speed as well as control it via PWM.

The lower voltage will definitely be reducing the fan speed; that's simply how electricity works. You won't see the fan speed change in the BIOS when doing this as there is no PWM on those fans to report fan speed.
As a test, you can set the speed to 0, which should stop the fans from rotating entirely. That will tell you if the voltage control is working quite easily.
 
to be honest I don't think it is working at all ie the speed of the three RGB fans does not change unless I use the remote control but they are set to the lowest already.

I need to revisit the BIOS to retest - I understand your point about the RPM not being visible now

I know I asked this on another thread but current fan setup is not PWM but there was mention of an adapter on here Noctua NA-SRC7 unsure they will work as my current fans are plugged into a hub that I assume is also functioning my remote control. I don't mind losing the remote control stuff it would be nice if the current fans would plug into the mobo - then I got a good chance of controlling speed but their connectors that go into the hub don't look standard..

Pretty much any fans running below 1200rpm will be silent. I've used some EZDIY fans, some corsair fans, Jonsbo fans, thermalright, noctua...
I would probably would suggest to get the fans with bigger impeller size. the problem with Ring fans or LEDs being around the perimeter of the fan - it reduces the impeller size and as the result amount of air it can move.

Ditch the controller, connect the fans directly to the board. Setup a fan curve in the BIOS. Can you post a picture of the fan headers?

No need for a fan controller with a remote. Is this 1999?
 
Ah, that looks like those 6-pin connectors that have RGB and fan power in one connector. I'm not sure if conversion cables exist for those but, if they don't, it's likely time for new fans.

You could depin them and install 4 cables into some new 4 pin headers but not sure whether this is within your skill set or not. It's an option.

So are we not looking at the power cables only?

As the RGB fans have another cable that iirc connects to the motherboard itself ie the 3 pins 5v connectors ARGB

Anyway, yep these cables are 6 pins
Im fairly competent myself, but I got to ask myself if:


A. Is it going to work?
B. Is it safe?
C. Is it inexpensive?

Is there a guide?

Otherwise, take out these fans and replace em with quieter fans that are connected directly to the motherboard
Choices.

This isn't how it works - 3 pin fans have negative, 12V positive, and a tacho (speed report) wire. Pin 3 is tacho. Adding the 4th pin adds the PWM control wire.

So any motherboard connected fan normally has speed reporting whether it's 3 pin or 4 pin, DC or PWM speed control.

And as seen above, OP's fans aren't connected to the motherboard for power or control and have the funky 6 pin to the controller.

I'd get new fans as generally, cheaper RGB fans aren't that good for noise/performance, even if they look good. I could rewire those connectors but not everyone could, and it's a pain Vs just plugging in new ones.

Indeed - I'm not sure what the options for conversion are. It would be pretty easy to understand the wiring from a multimeter and then repin them in different headers. Fans are just motors, electronically speaking, at the end of the day. The safety and functionality is more down to your skill level. All valid questions. In terms of time to solution, new fans are going to be the best option.

Yes, definitely go for 4-pin PWM fans and connect them directly to the board or a PWM-based fan hub.
 
Well well well new fans it is
And as its jan…. As soon as one of the reccomended fans hits £5 i might jump

Did i tell u all that i once got rgb fans for £3 each? Bargain those fans were so quiet but their led output v poor and hence i changed to the diy fans

im hoping to secure a new 1/2tb nvme on a sale and remove the ssd’s so i can smarten up the cabling inside the case
It looks woeful

Happy new year lol
