Rattle sound on 7800XT

[jnos]

Hello. I noticed my nitro+ 7800xt makes a weird rattle sound above one of the vent when running a high RPM.

You have to be really close to it to hear it, but I don't understand at all what could it mean. Any help?

Thank you.

On my nitro+ 6900 the fans would break on high speed and would make a high pitched scratchy sound since the plastic was broken near one of the fan blades on the outer plastic rim, not the blade itself. You can buy a kit on Amazon to replace the broken fan if that is the problem. I had to replace all of the fans at one time or another until I got 3 good ones. The ones from the factory are cheap in my opinion.

What noise?

 

[GerKNG]

sounds like a loose fin from the heatsink to me.

Cant hear the noise but the rattling could mean bad fan bearing

Id take the system out of the case and run it to isolate 3 fan components, cpu, gpu and psu, no other fans, if noise goes away then its eithe vibration transfer to case or another fan in the case making noise

Also people should ensure no cables are touching any fan

Is it bad? How can I fix it?

How about properly isolating the problem first before jumping to that?

Can you not set the RPM manually to a value that doesn't produce that rattle ? From what you have shown us, it sounds like you put those fans manually into tornado mode. How about finding a more reasonable value ? 7800 nitro should be quiet out of the box, why would you need to run high RPM ?

Sapphire Radeon RX 7800 XT Nitro+ Review - Fantastic Overclocking

Sapphire's Radeon RX 7800 XT Nitro+ is the quietest RX 7800 XT reviewed today, it's virtually inaudible at full load thanks to its powerful cooler. The card is also the best overclocker, it gained a spectacular 15% in real-life performance, which makes it nearly as fast as RTX 4070 Ti.

Yeah can't hear nothing, user probably needs noise cancelling mic or to do that, I did mention to isolate the system out of the case earlier but op seems to have ignored advice in a situation like this.

It is quiet, as I said, you have to be really close to it, basically few centimeters close.

 

[eidairaman1]

Have you even played your video back

The sound I'm hearing could feasibly be coil whine as well. It should be pretty easy to tell which, just stop the fans for a moment when you are hearing this noise by pressing on the fan hubs and if the noise stops it's the fan. If it doesn't it's coil while (or a different part in your PC but that should be pretty easy to differentiate).

If it turns out to be the fans you can turn the PC off and inspect the area around the fans for anything that might be clipping the blades or that's loose. You can slowly spin them to see if anything gets caught.

My Zotac makes some noise if the card is not slotted in perfectly straight. My case comes with a GPU support, and I use it to tweak the card just a bit to avoid that noise.

I thought it was my fan failing, since I read Zotac has a history of that, but pretty sure these are ball bearing fans on mine, they are pretty noticeable at 3000RPM lol..

Since I give it a little tweak, I hear not a peep.

Yeah bbs are great for durability and speed due to reduced friction contact but not for sound

I listened to it now and no noise. I dont understand.

 

[eidairaman1]

Probably something else

You should try and reproduce the conditions under which it originally appeared. This includes running the exact same applications. At least then you can start isolating variables to find the root cause of the noise.

 

[jnos]

I did. And the sound, although very quiet, reoccur. So I stopped the right fan gently and the sound stopped. So I guess fan is hitting something? I used compressed air, but nothing.

Take it out and inspect it carefully.
How old is the card?

Fans can build dust on the inside side of the blades. Usually dust is not distributed 100% evenly on all blades. This can throw off balance and put stress on bearings.

The same thing can happen if the blades weren’t thoroughly cleaned on both sides.

When I decide to clean any fan it will be on both sides with a vacuum and a dust cleaner on the tip, even if that means I have to take off the GPU front shroud.

I see. However, does it "hurt" the GPU now?

It could be the bearing, the fan contacting something, or a loose bit of material (or perhaps an under tightened screw) near the fan that's vibrating during high fan speeds. Try taking the card out and inspecting the area around the fans. You can try spinning the blades to see if you hear that noise at all or if they come into contact with anything. If there are screws keeping the fan in place it couldn't hurt to ensure that are adequately tight (if mounted in plastic please take care not to overtighten).

Great recommendation!

I will try it, thanks. But do you think it might damage the GPU in some way? thanks.

If that specific fan making the noise from its bearings it could mean that it’s already damaged. Nothing is certain though. If it’s from dust it may stop when you clean it. If it’s from something distracting the fan rotation it may stop if you get it out of the way.
If it’s “simple” a vibration it could mean that the fan is degrading from usage.

This all is just guessing right now…

The GPU is not affected directly but in long term if the fan performance degrades it will affect the GPU and VRAM temperature.

From what I’m seeing from pictures of Nitro+ 7800XT the fans are same type as my Nitro+ 7900XTX.
They are very nice and quiet/silent fans up to 2000-2100rpm. Low noise up to 2400-2500rpm. Max rpm at ~3200rpm

I asked before and didn’t get any answer…

And did you use the zero rpm option from adrenaline or the fans are spinning as long as PC is running?

A noisy fan, regardless of if that's from an obstruction or bad bearing, does not have the potential to damage the GPU. If the fan were to break or suddenly stop working you still have two other fans and GPUs have over temperature protection.

Plus a fix to catastrophic fan failure is cheap.
