Question Loud GPU fans ?

[Mikay]

Hello, i have problem with my Gigabyte RX 7800 XT GPU. It's fans are very loud when I'm gaming.
The only solution is to cap the FPS, then the problem dissapears.

Under the links below are temps from HWMonitor, after 5h playing Warhammer 3 (with FPS cap on) and how it sounds without FPS cap.

Thank you for all your help. I want to add one thing, my problem with loud fans appears in Warhammer 3 and Space Marine 2, but in Diablo 4 and Space Marine 1 they run very well without FPS cap.

Sounds like a normal airflow "whoosh" of GPU fans.

As of them being loud, well, that's how all powerful modern day GPUs sound like.
0 noise = 0 cooling and with such power hungry GPUs, this can't be done.

Limiting FPS means that GPU doesn't have to work on it's hardest. And when GPU isn't working at it's hardest, it doesn't heat up as much - thus, fans doesn't have to go 100% tilt.

As of fixes, well, besides the FPS cap you have already found out, one thing that helps a lot (i do it myself), is using headset for in-game audio. When you have good headset with good outside noise cancellation, the airflow noise isn't heard and you can focus on gaming.
Other options include limiting GPU fan RPM (but that can lead to GPU thermal throttle), having a GPU that is designed better with quieter fans (e.g MSI GPUs that i'm personally using for this very reason) or increasing the cooling of the whole PC (via case fans), so that GPU doesn't heat up that much. Or you can also learn to live with it.

Overall, there are no solid fixes. There are workarounds that may not fit for your taste.
Well, definitive fix would be putting the PC into another room and then routing the monitor and peripheral cables into your gaming room (in lieu of how servers are set up) but that takes the most amount of work. But it would eliminate the noise problem for good, without replacing hardware and/or limiting FPS/fan RPM.

Thank You for Your response. I have only one last question, are my pc temps ok?

All well below 80C, don't see any issue there.

I know i said that was my last question, but i have one more, last (promise). In my pc case i had 3 top exhaust fans, i read that is not right air flow so i unistall one of them, it was good decision?

Says who? 🤔

PC airflow rule of thumb: front & bottom - intake; top & rear - exhaust (since hot air rises due to natural convection).

Most PC cases nowadays are configured towards negative pressure, by offering more exhaust fan mounts than intake ones.
On cooling aspect, negative pressure is best, followed by neutral and then positive pressure.
Downside of negative pressure is dust, since it sucks dust in from all the small gaps your PC case has.

Here are the three air pressures visualized:
(Btw, i have the same PC case but mine is black in color.)

so i unistall one of them, it was good decision?

Even with one of the top exhaust fans removed, you still have negative pressure inside the case. Not as severe as before, but negative pressure still.

On cooling aspect, removing one exhaust fan may impact the whole build a bit (it runs a bit hotter). But not enough to make a big difference, since fan removed was closest to the front and had little impact on the overall airflow of the PC case.

To be honest, i was on the 5 forums with my gpu, before i got here . And everyone said i should remove that fan. So its dosen't matter if i left or keep this fan? And more thing, im so grateful for your response , because everyone said i should undevolt gpu or change fan curve or send it back on the service. And You calm me down, thank You for this.

Impact on overall PC cooling is low. Removing that fan means less severe negative pressure inside the system but it should not make much of a difference.
You can check your CPU/GPU temps with the fan removed and look if average temps increase few degrees or not.

because everyone said i should undevolt gpu or change fan curve or send it back on the service.

Undervolting GPU (or CPU) in my opinion is pointless. You can fry the hardware for good if you dabble with voltages.

Changing fan curve is one option, but keep in mind that reducing fan RPM also reduces GPU cooling, which can lead to GPU thermal throttle and end result is far worse than just hearing the airflow "whoosh".

And no point to RMA the GPU, since the airflow "whoosh" is normal operation of the GPU.

In a similar sense; it's like you're buying gasoline (or diesel) powered car and don't like the engine noise (especially at higher RPMs) by citing that it isn't as quiet as electric powered cars are. Well, engine noise is normal operation noise of gasoline (and diesel) powered engines.

When to think about it, 🤔 at current day and age, you can not escape airflow "whoosh" in desktop PCs. Not even when you use AIO or open-loop cooling, since for those, they have radiators and fans on the radiators, that still create the airflow noise.

Only two options without any airflow noise would be:
1. Fanless system (doable but not at high resolution and high FPS, since fanless GPUs are very weak).
2. Submerging entire system into special non-conductive liquid (currently innovative server cooling).

For 2nd option, here's further viewing:
