Hey all... I'm getting the "NVML: cannot get fan speed, error 999 (an internal driver error occurred)" error... cannot isolate it to one card (all 1060 6GB, but of different makes). Every time I take one suspected card out and put it to a separate instance, the main group still throws this error. I add another to the suspect group and still an error.... and so forth until I can fairly say that no one card is at fault. All but two risers are powered by PCIe, the other two are molex,  but on separate cables. Total power usage of the PSU is no more than 80% at any time. I _think_ I'm doing everything right. I've even tried saving the OCs so that when I quit Afterburner, they still hold. (Thought it might be AB's monitoring that was interfering.)

Here's the thing, though... unlike other people, this error does _not_ cause the miner to restart nor does it cause anything like windows to freeze or restart. Plus this error does not show up in the logs straight away, it typically takes 4-6 hours.

Now I know what some might say... "if it isn't crashing, don't worry." But I can't help but think that if this error is being reported, it's for a reason (a hit on number of shares earned, bad connection somewhere, impending doom ;-) ) ... or there could simply be a bug in the program.

Thanks for any hints as to what might be going on.

P.S. I am using 11.6 and 391.35 and did not have this issue when running 1050Ti's on the same rig.
