It’s likely that your card is boosting clocks up until it hits the power limit but the reporting error is causing the power readout to show a number below 100%. Under these circumstances a dramatic increase in fan speed would cause some extra power draw and the GPU voltage and clocks could be dropping in order to stay within the maximum power limits of the card.
We’re working on a fix for the power reporting error and expect to have it available in a few weeks.
