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?

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

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?

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

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

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

Who knows, could have been me without realising for all I know
