My card: EVGA GeForce RTX 2080 Ti FTW3 GAMING.

My graphics card has three fans. The first is always running. However, GPU-Z shows a Fan 1 and 2 which look as if they are really the same fan. When I load my GPU at 100% the other two fans kick in but GPU-Z still has the same two fans showing. They do have higher RPM's but they are always the same value. Comparing fans using HWinfo it will only show one fan when the GPU isn't under load and when all three fans are going they will all be displayed with slightly different RPM's which tells me, unlike GPU-Z that fan 1 and fan 2 are not the same fan. I think the problem lies in i2c.

I also have a similar problem with the program SIV. I am working with the Developer on fixing this as I speak. He is the one that says it's an i2c issue. I sent him some dumps for debugging.

Not quite, I said SIV had an issue with reading I2C which is subtilty different and now resolved.

Either way I expect I adjusted SIV to report all 3 fans and in the last save file you sent on 2019-09-06 @ 09:23:49 it did (Note fans 1 + 2 were reported twice, once via NVAPI and again via the I2C). Since then I have tidied things up, but I can't find a reply to my email about this, did you send one?

I suspect SIV 5.42 Beta-11 may report your Sabrent Rocket NVMe disk SMART data even when stornvme is used.

Good luck with getting GPUZ fixed and I hope you do better than I did with the bugs I have reported in GPUZ.
