GeForce RTX™ 4090 SUPRIM LIQUID X 24G

[Vector Sigma]

Hello,


I have this card and recently I notice the fan underneath the card never spins.

I've tested this GPU by running Furmark at 4k resolution and even on Fire Strike (Ultra), so it's running at maximum load (more or less), but it still won't spin?

I made a video to demonstrate, if someone can help.

Filebin | wn0hcxycat1fxh1h

Convenient file sharing. Think of it as Pastebin for files. Registration is not required. Large files are supported.

filebin.net

Is it a setting issue or an issue with the card?

Thank you.

What temperature is it at while running furmark?

Edit: nvm didn’t see the video on mobile, now can see the temps are in the video

About 80-83C.

Your video have been deleted now so I can't see if you mentioned this but have you tried it in both modes via the Silent/Gaming switch? At 80c you'd expect it to be spinning even in silent mode, but it would be worth checking out gaming mode anyway just to double check if it does/doesn't spin in that mode

I re-uploaded the video elsewhere.

Can you help where I can find that setting? I have a Asus motherboard and all the settings seem to be CPU related.

When my 4080 arrived with a dead 2nd fan I used GPU-Z to show the fan was being commanded to run at a certain % but the actual RPM stayed at zero.

Download and install GPU-Z. Under the Sensor tab you should see a % & RPM for each GPU fan.

Hi,

This is what I see.

 

[Vector Sigma]

Download MSI afterburner and you'll be able to control the gpu fans from there. See if they even spin up when you set them to manual control. That's where i would start for a easy diagnosis.

Where do I find this setting?

I don't see it under the fan tab.

 

[Vector Sigma]

It should be a physical switch next to the power socket:

I'll see if I can find it.

I did reformat my PC. I'm not sure if that had something to do with it.

 

[Vector Sigma]

It should be a physical switch next to the power socket:

It's set to Gaming Mode.

Click the Sensors tab and look for the entry for each Fan % & RPM.

My RTX 4080 has the below
Fan 1 %
Fan 1 RPM
Fan 2 %
Fan 2 RPM

If the Fan % is reading say 30 and the matching RPM is 0 then the fan is not working.

Hi,

The 3rd fan doesn't even show:

 

[Vector Sigma]

im assuming the fans on the radiator are connected to the gpu and not via external cables? Not familiar with this version of the 4090 so im only assuming.

Also assuming its the single gpu fan that's not spinning and not the radiator fans?

Yes, the radiator fans working fine, but the single GPU can are not.

I'm not sure about the first question.

 

[Vector Sigma]

That option is redundant for me.

 

[Vector Sigma]

in your video when you set custom fan curve did you also select fan2 at the top or just fan1?

afaik looking at it fan 1 includes both radiator fans and fan 2 is the gpu one thats doing nothing so try setting that manually.

when you start up the pc do all 3 fans spin up when you turn it on? if not its dead fan

cant believe i logged in just for this

Hi,


I appreciate your help.

Here you can see I've set fan 2 to maximum and GPU shows no RPM.

fan 1 is also set to maximum and GPU does acknowledge the speed and the RPM.

fans dead, needs RMA

Bummers. So, do I have to send the whole card back or will they send a replacement fan?

 

[Vector Sigma]

normally have to send the entire thing back and hope for the best, hope you havent had it too long

A few months.

Cheers.

 

[Vector Sigma]

Hi,

Does anyone know what other fans can fit inside this GPU?

 

[Vector Sigma]

Not worth doing it yourself. It is defective and still under warranty, Start an RMA.

They're also asking for the entire card. I can't do that.

I'll buy a replacement fan and get an expert to replace it. If it still doesn't work, I'll start an RMA.

 

[Vector Sigma]

Unless warranty covers DIY you are going to void the warranty.

I'll put the original one back on if I need to send it back.

 

[Vector Sigma]

Can you see to check that fan wires are connected on the card

They are.

 

[Vector Sigma]

I had the same with my old Zotac 3080 and they wouldn’t supply a single fan and wanted the whole card back.
I got one from..

Graphics Card Fan Replacement - All models for all GPUs

All models for all GPUs

gpu-fan.com

and replaced it myself.

Hi,

Can you help me to see if that site has the fan I need for my GPU, please?

 

[Vector Sigma]

Just email them, they’re super helpful & delivery is quick.

I have. Thank you.

80+ at 450W on an AIO is also concerning. What RPM are your radiator fans at ?

MSI have warranty stickers which void warranty in the UK so really no point doing it yourself.

The radiator fans 2348 RPM.
