Thanks for checking out my sale!
This Zotac RTX 3090 used to be part of a video transcode station at a production company. It was part of a custom made computer where the GPU PCB was water cooled (you can see it in one of the pics I've included) The computer was decommissioned so I ended up buying a heatsink and cooling fan from and moved over the PCB so I could use it for gaming. It worked out pretty great! I've moved on to a 50 series then so I no longer have need for it.
Under heavy load the fans can get a little loud, just be aware of that if you're sensitive to fan noise. I've tried capturing some of the noise and performance on the video I uploaded.
I also took a picture of the real serial number, which I can provide upon delivery.
Any questions, please let me know.
