This video is fantastic, I never took the time to properly configure fans in the past. After watching this, I feel like I've finally got things quiet and cool.

[haakoflo]

200dB (dB(SPL), the dBA scale is probably undefined at this level) is just enough to cause death in a human. Eardrums rupture at 190.

Even if you do manage to double the SPL (Sound Presssure Level) at points where the sound from two speakers are in phase, that will only add +3dB(SPL), by definition. A 100dB difference in SPL means that the pressure is ~2^33 or about 8 billion times louder.

Fml. Thank you in particular for that info on resonance when all fans run the same speed.
Now I know why I had such a hard time finding a quiet configuration for my system.
I had turned off every fan but one and checked at what rpm I started to hear it (all fans were the same model of course), and then set all the fan curves exactly like the first. To my amazement and frustration I could suddenly clearly hear the fans. After a lot of testing I did end up staggering the different fans slightly, since that seemed to help. I just could not figure out why it helped.
Finally I am at peace ;)

Thanks for the very informative video. Just wanted to give a little decible calculation correction. When adding dB, they increase on a logarithmic scale. 100+100=103dB. It still sounds 2x as loud as 100dB, though, so what you said did make sense.

I'm gonna spend some time reevaluating my fan curves. GPU hotspot/CPU is currently sitting around 70C/40C while fans are producing 42-44 db of noise. But it still seems a little loud, i can definitely hear the cooler's pump still.

[dhruvmeena]

As an acoustic engineer, he is right.... All fans at same speed create resonance peak multiplied by the factor of fans...

If set of fans are on different rpm, you can smoothen the whole frequency curve ..


Also, push rad fans harder than intake :)

+ There is case resonance and that can make things worse or better on how fans are adjusted


High speed means higher rotation per second
Which can be converted into wave

So a 3k fan will peak at 3kHz and it will be apparent

A slow rpm will generate low notes

And as said by earl gedlee, its the high frequency noise which is more apparent and damaging than low frequency and if you start moving in 500Hz to 5kHz range, this is speech intelligebile region... So higher frequency will sound worse and worse..

And a fan with crazy high rpm can even sound like screeching

[Gamingtechgg]

Smart Fan you could use also if you got aorus motherboard. It can do auto calibrate or you can fine tune with custom fan curve to your liking. Works great.

[olofdankert]

100 Decibel + 100 Decibel is not 200 Decibel, it is a logarithmic scale. Nice to find one small error in your excellent video 😘

My mobo has 4 Chassis Fan Connector, in addition to the 2 CPU ones. I plan on taking advantage of that to have the fans not just at diferent speed. But to not have all running at all time (off or really low). So if I leave the computer just downloading something. It's just exhaust on the back and one of the intakes on the front. And when using it, as load increase fans boot up and speed up individually. My GPU has a thing it shuts the fans when not needed. I have that off and just to run slow, out of paranoia. I've also have seen some PSU that have that feature that turn off the fan when min load.
I really like the idea of keeping the fans as high as you can without noise. You'll most likely tune it out. And only notice the fans when they need to boost. And by keeping them relatively high, you won't really need to unless you are truly stressing the PC since you'll be keeping it steady cooled.

[krautergarten]

That high idle fan speeds will maximice your dust deposition. The flatter your fancurve is the less ramping up down noise u will get. U have the steapest fancurve possible. Why not tuning it to 30 or 35db in normal workloads intead of +40db? With a linear curve from 20%/30°C to 70%/90°C to 100%/100°C. Offset the different headers by 3-5°C to spread the spectrum. It will be quieter and less dusty ... test it with u db meter 😉

[Last]

in gigabyte bios u need to hit TUNE ALL above the different headers. that way you can put the curve u made on any or every header. saves alot of time. pro tip

[BMH]

@17:55 +3dB(a) used to be considered as a perceived doubling of the sound volume (recent research suggest a doubling is reached at +5dB(a)) - meaning that the effective perceived sound level is doubled (according to traditional conventions) with the new fan configuration when under stress compared to idol.

[chrisrosenkreuz]

conversely, if your environment is already noisy, running all fans at the exact fan curve will cost you less electricity seeing as they resonate which makes it less harder to push/pull the air

[lancecampbell]

Fantastic video. Thanks so much for making it. I learned a lot.

[jeroenvdw]

Fractal Design Torrent here with fan curves maxing at 50%. Still incredibly cool and the thing is very quiet, even when placed on my desk like 20cm away from me.

[Lechebrin]

I have configured fans in the BIOS, but I think they still act according to Gigabyte Control Centre. How to disable GCC fan configuration?

[clausbohm]

Good points, thanks for the heads up on these fans!

[jokerbeatzholyjesusinspira]

The best way for me was to take advantage of my p400s phanteks.
It has a button for fan control with 3 levels .
I just plugged all of my fans to that controlee and boom, i have a quiet pc easily

[AshRealm]

Resonance depends basically on sound frequency.

[DrSatan]

This seems like a way smarter way to do this vs traditional techniques. Thanks!

Here to see if I need to start resenting the choices I made with my new PC last weekend. 😂
