Hi All, I just bought a GTX 1070 MSI Gaming X and I've got an issue with fan speed. The fan tachometer doesn't appear to be working. I cannot get a reading for the fan speed in RPM. Afterburner, GPUZ & CPUZ all report 0 rpm. When I change the fan speed in Afterburner... the fan speed does physically ramp up because of the increased noise generated. However, the tachometer still reports 0 rpm and I cannot decrease the fan speed. In order to reset the fan speed I need to power down the computer and restart. This is an issue when gaming as the fan will ramp up to what sounds like 100% and will not decrease even when there is no gpu load. Should I return?
Card has semi passive FAN that can cause problems. I suggest you enable user defined fan speed on Afterburner and see if that works.
You may also try these other overclocking softwares to confirm that the problem is with the card only.
