Question RTX 3070 FE zero fan feature?

[fleshconsumed]

Managed to score 3070FE from BB a few days ago. It's my first nVidia card in 6 years for me. The cooler is not great, but lowering voltage curve and power limit helps a lot to keep the noise kind of reasonable. I'm having issues with zero rpm feature. My fans always keep spinning at 1000RPM.

To summarize:
- 461.40 drivers and MSI Afterburner 4.6.3 beta 5
- Fans always spin at 1000 rpm no matter what I do
- Core clock varies between 600-1000Mhz, memory clock 810Mhz, power used 30W (multi-monitor setup with 3 monitors), current GPU temp 39 celcius
- I've tried shutting down MSI afterburner and fans still spin
- I don't think I have RTX Broadcast installed (how do I check?)

No matter what I do fans always spin. Does RTX 30 series not have zero RPM fan feature? Can I set it somehow to stop the fans in idle?

multi-monitor setup

At least, back in the olden days, this would kick the card up into a "higher-powered state", even if no 3D applications were started. It wouldn't really surprise me if the Zero-RPM fan feature didn't function, when in multi-mon mode.

Well, my card dropped fans to 0 RPM today. The GPU temp is about 50 celsius. So it does have zero rpm fan feature, but I have no idea what it uses to decide to stop the fans...

My RX570 also has 50°C as a trigger for its zero RPM mode. Also there are different power states for different refresh rates it seems. Your 3070 might have this too, probably.
Example: When I run Windows desktop at 120Hz (freesync on+DisplayPort), I get 10W idle from the GPU. When I up the refresh in Windows to 144Hz (same freesync on+DisplayPort) the card shifts into another power state and suddenly never goes lower than 24W when idling.
BTW I will probably get a 3070 FE soon.

Yeah, my old Radeon HD6850 would double its idle GPU clock when a second monitor was plugged in.
