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?
