Hi,

I have a simple question!

I just installed my fan setup, I have 4 intakes fan and 2 exhaust So obviously I knew it was gonna be loud when they run 100%!

So i heard about the software speedfan, so I went in the bios and set my fan to Silent (which is 30% in speedfan software) and they doesnt do any sound! Perfect for my girlfriend when she does her work on the computer!

So bassicly when I'm gonna game Imma get on speedfan and turn them at full speed which gonna get my 1080ti in a stable 65 celcius at full load and cpu 50 celcius while gaming PUBG in ultra. And then when i'm done gaming put it back to 30% so they dont make any sound and still spin. So is it a bad thing to do? To set it in silent in bios and change it with speedfan?

Heres my fan setup in case you guys ask me:

The h60 means I have a watercooling fan in intakes for my cpu, corsair tells in their manual to put it that way for better cooling

You would then have 3 intake and 3 exhaust which is balanced, and a setup you want to shoot for. Ultimately orientation is up to you. This was a suggestion. You can try it both ways and see where your temps are (all your temps. Use something like HWMonitor and monitor all the system, cpu, gpu temps). If your cpu temp is low but your vram is choking, that's not good and it will affect cpu performance all the same though I doubt you'll get that extreme temps.
For the gpu fans, whoever makes the gpu should provide a utility to control the gpu's fans. For example, for MSI it's Afterburner. For gigabyte, it's Xtreme Gaming Engine and so on.
For the case fans, I'm fairly certain that speed fan will allow you to basically make a temp curve...

Well, I have purchased à 1 to 2 fan connector x2

Which I connect 2 fan to CHA Fan 1

And 2 fan to CHA fan 2.

and I have control on them on Speedfan software.

So is there a CONS about controling them on the software instead of the bios? I would of use the bios IF I didnt have to reboot the computer every single time I want to put them full speed when Im gaming, and reboot to put it back to 30% speed for my girlfriend...

So whats the cons?

The cons are that speed fan is programmed by a single guy and he doesn't have access to all the possible motherboards. Consequently your mobo sensors may not get recognized and you won't be able to control fan speeds of your fans. If it does, then great.
But if you can control it from bios, it's likely that your motherboard manufacturer supplies a utility which will access this bios info from windows and allow you to change fan speed yourself. Advantage being that you know it'll be compatible since it's coming from the manufacturer, disadvantage being that if it's an older board, these utilities may not work with it.
Your h60 should really be on exhaust as you don't want all that warm air from your cpu blowing across your vrm, capacitors and memory. You want it blown out of the case.
As for fan setup, speedfan I know allows you to set up temp curves, where it automatically changes the speed based on cpu load. You shouldn't have to manually switch speeds from idle to load.

Yes I know that, but 3 exhaust is a bit overkill?

And as for the fan, my cpu temp is fine with the h60, I'm changing the speed mainly for my gpu.

Before a put up the fan the gpu temp was always 70-79 celcius, now 60-69... so I'm changing the fan speed when gaming on pubg ultra which gets my gpu to be 99% usage... thats why I dont customize it in the bios because its only customizing with the cpu temp... im using to fan to cool the gpu...

So once again, when I game, I put the fan on 100%. Wheb i quit the game, I put it back to 30% so the fan are quiet for my girlfriend... it wont break anything right?

For the case fans, I'm fairly certain that speed fan will allow you to basically make a temp curve for a fan based on the GPU temperature if speedfan is able to get the sensor reading, so that you do not have to manually switch it. However, if you don't mind doing it that way, that's fine too. Nothing will break, no.

Thanks you for that simple and clear respond.

Yes, temps are all good with this setup! Cpu 40 iddle and 50-55 while gaming. GPU 60-70 max load with msi afterburner.

Yes I already have a curve setup for my GPU fan using afterburner! I was talking about the case fan in this thread!

When my case fan are running 100% while gaming, my gpu temp is 10 celcius lower than when I have it 30% in silent mode from bios.

Like I said, in the bios theres only a curve setup using CPU temp, but I dont care about cpu because its always stable with the h60 watercooling. Im using to case fan intakes mainly to cool down GPU.

Maybe in speedfan software theres a gpu curve based setup for the fan, I didnt see it, I will check that out tomorow, which is gonna be good for me since my gpu temps is 45 celcius iddle and 60-70 maxload. So its gonna change the fan speed by itself for when my GF do her work (iddle) and when Im gaming( max load).

I think speedfan may give you this capability depending on what sensors it's able to read from your mobo and gpu. Something like:
https://linustechtips.com/main/topic/154956-how-to-properly-set-up-speedfan/
but obviously not pwm fan since it's likely your chassis fans are voltage controlled instead. If it can't read the gpu temp sensors and doesn't offer it as an option when setting up the fan curve for your chassis fans, then it's a no-go.

Another possibility is to sometimes gpus will allow you to plug chassis fans directly into them. If your gpu doesn't have this fan header, then this isn't an option.
