Question 2080 Ti FE GPU - - - fans are stuck at 100% and I can't change it ?

[Osoken]

I had a 2080TI FE that I sold to a guy that I made sure to test fully beforehand, and everything was ok with it. It passed the 3DMark Benchmark test and stress test and the fans were fine before. I ship it to the dude and when he receives it he says the fans were spinning at 100% non stop. I had him DDU his old gpu drivers and install the 2080TI but no luck. Next thing we tried was using afterburner to mess with the fan curve and the manual fan slider, but neither of those things helped either. I also had him plug the gpu into his brothers PC but same situation. He didnt want to take it apart (and not like its easy at all to take these apple like devices apart) so I had him try to flash the vbios. After following a video I sent him, the fans were still running at 100%. Does anybody know what could be the issue??

His specs:
Graphics Card: GTX 1070 8gb
CPU: i5-10400F 6 Core / 12 thread 2.9Ghz Base CPU boosting up to 4.3GhzCPU
Cooler: 120mm Cooler
Motherboard: Dell Alienware R11 OEM
RAM: 16GB DDR4SSD: 512GB NVME SSD
HDD: 1TB 7200RPM Storage Drive
PSU: 850W 80+ Gold Alienware OEM
Case: Alienware R11 OEM with ARGB lighting

the fans were still running at 100%

how was it proven that the fans are running at 100%;
multiple monitoring software instances,
just noise produced, etc..?

it's possible that both systems it was tested in have a 3rd party app installed;
like motherboard control software, etc that are countering any manual input for such devices.
if both systems are some OEM prebuilt they may not even have control over options like this.

He sent video of the fans and showed me everything he did on video. I could hear the noise and he showed me in HWInfo that the fans were at 1500 rpm, although one of the fans said 0 rpm as well (could be that the gpu is freaking out that one fan isn’t spinning??) but i saw that both were spinning so maybe that is the issue. Coincidentally both PCs are alienware OEM pcs or dell, but he bought two from me actually, and the one he gave to his brother works fine in both PCs, so i ruled out any of that 3rd party software.

showed me everything he did on video...one of the fans said 0 rpm as well

in the video you could see one was inert, @ 0% RPM?

i know there were a lot of users complaining about issues with these Nvidia FE branded models when they first came out.
if these are from one of those early batches maybe this one is just starting to show it's faults.

could be that the gpu is freaking out that one fan isn’t spinning?

yes, if one fan is not working then the other is going to increase RPMs substantially.

have them just flick the blades in the correct direction while in use and maybe it'll start spinning.
i've seen many case/cooler fans get semi-locked up before.

No no, both of the fans are physically spinning. but HWinfo reads fan 1 as 0 rpm and the other fan at 1500

the other card's fans are reading normally
and fan curve is able to be set manually on the same system?

always possible a fan sensor was damaged in packaging/delivery/installation.
temperatures seem normal.

unless the fans are extremely loud and the sound is bothering someone, i'd say just leave it as is.
one of the downsides of buying used products.
