between 2 PCs, 5 cards tested, all exhibit the exact same behavior. 3 were from one retailer, 2 were from a completely different retailer.
when under load (>90%) the fan rpm keeps dropping and sometimes spike to 3500rpm. even if set to manual fan mode,doesnt matter which speed I set it to, fans will run fine until I give it a load >90% such as playing a game. doesn't happen when doing desktop work, or even running realbench regardless which speed I set it to. gaming/graphics benchmarks only. tried latest and past drivers. tried setting custom fan curves, manual fan settings all speeds, doesn't make a difference.
the sound is annoying with it constantly revving during gaming. just curious what it could be? it'll run for 5-10 seconds, then starts getting these spikes and drops, and it keeps repeating.
