4090 Founders edition Fan failure

[Klunt Bumskrint]

I bought a 4090 recently from the MM that was under a waterblock, when it arrived I took that off and put the original cooler back on. I didn't notice until today that the fan just doesn't work, can anyone think why this fan would not be working?

I've double checked she's plugged in properly. Anyone else seen this before?

 

[Mcnumpty2323]

Silly question maybe
Do founders edition cards have fans that don't spin
Until a certain temperature?
Never had a FE card

 

[Kirby Wurm]

Does it spin up under load or never?

 

[Klunt Bumskrint]

I should have clarified the fan underneath runs as expected but the fan on top doesn't turn on under load or not. I know they don't spin unless it needs it but this hits nearly 90 degrees and the fan (on top) doesn't start

 

[Mcnumpty2323]

Yeah nearly 90 is too hot
It would spin well before that

Tried spinning it with your finger?
Might just be a bit stuck as been off for a while

I would speak to the seller maybe
Though not sure how that would work tbh
They sold the card as working i assume
But that was with the waterblock fitted
Not sure how it stands about the original heatsink fans

At least replacement fans are available
However it turns out
And not expensive if you don't mind the wait from China etc

 

[Klunt Bumskrint]

It's not stuck it does turn when you try. The seller didn't use the cooler because of the waterblock. I can get a replacement for about £15 from aliexpress. Is there anyway I can test this fan to see if it's dead?

 

[Mcnumpty2323]

Not sure how you could test it
From looking at replacement fan pictures
It's some sort of ribbon style connector?

Unless the other fan also uses the same connector?
Then you could double check
Both the fan and the top fan pcb connection

 

[Klunt Bumskrint]

Found the problem, small crack in the ribbon cable. Good to know
I'll order a replacement

 

[Glanza]

If / once you get the new ribbon the fan should automatically start on boot then go off until it kicks in once the GPU hits 50c.

 

[Mcnumpty2323]

That's unfortunate
But still better news than if it was
The fan connector on the pcb was damaged

 

[Klunt Bumskrint]

It's the risk you take when buying used stuff I suppose. I've actually been pretty lucky, bought quite a few used GPU's in the last 25 years and never had an issue till now.

Just sods law
It would be on such an expensive gpu

Must admit I was tempted by that particular one you got in mm
Just couldn't justify the cost
For what gaming I do though

Lol, nor could I but at least it shut my brain up from telling me I needed one

Mines still nagging me
There's another waterblocked one on mm now
Must keep telling myself
Don't do it,don't do it,don't do it

[Klunt Bumskrint]

New one on the left
Fan arrived today and problem solved.

Just fitted it and it seems as good quality as the original though it's a rev.3. AliExpress to the rescue.

did they chew the ribbon cable out before puttiung the block on

 

[JediFragger]

Nice one.
