I purchased a brand new Gigabyte 3090 recently and put it on my rig. Within the first 24 hours I started getting an error where the fan speed was showing an error (see below). If I reboot, the fan speed does show up for anywhere between 5 min to 3 hours, then I get the error. The card still hashes and the temps are displayed, but the fan speed disappears.
The fans are physically moving on the rig and I’ve swapped the cables, PCIe risers and even put the card on a separate rig but still get the error even on the other rig. I also lowered the OC settings and the problem still seems to persist. I updated the NVIDIA drivers today and still get the error. No idea what I should do now. Is it safe to keep running this card in its current state? Since I just got it, I can take it back to the store but they don’t have any stock of replacement 3090s and likely they’ll tell me to RMA it (no return policy). Also, I don’t know if this problem will even show up if its used in a windows environment (haven’t tested that yet). Any thoughts?
