Could you post a screenshot of the corsair link home tab please. It sounds like your fan speed is grouped with the CPU temp so it responds according to that. Try grouping the fan speed to the coolant temp which is much less prone to sudden up and down spikes. This should solve the problem. You can also take a little bit of time to setup a custom fan curve and tune it a bit to get the performance/noise levels exactly where you want them
