Sapphire Vega 64 Nitro+: I don't know why this card has 1200 RPM as a minimum fan speed. By default, semi-passive mode is enabled, but it can't stay in passive mode for a long time. So it's like a few minutes of silence, then a few seconds of 1200 RPM horrible vacuum cleaner sound. On previous driver versions I was able to decrease minimum fan speed to ~700 rpm. The new driver (with new wattman interface for fan tweaks) doesn't allow me to do that, I can't move any point lower than 28-30% - 1200 RPM. Is there any solution other than downgrading the driver?
I also have a Sapphire Vega 64 Nitro+ (11275-03)
They have broken the fans with 18.12.2
Fanless mode at low temps is totally broken with this even at stock settings it runs at 1255 at the lowest (reset to default in wattman)
Its default fanprofile is
Minimum 300 rpm
Maximum 1500 rpm
Target Temp 70
it runs at 1255 rpm min now with and like 2700 rpm at 70 the 70 target
totally broken
maybe you lot should test your best 3rd party card before rolling this crap out
