WX 4100, Fan Curve not accurate #311

Open knuxyl opened 5 months ago

Checklist

Bug description

Fan is running about 20% faster than what the curve is set to. I've been watching it for 30 minutes and it never slows down. I tried changing some settings but it seems to give a consistent ~20% increase of set values to fan speed.

I was originally using amdgpufan service to control speeds through a configuration file and it worked as expected. I disabled the service, installed this, enabled the daemon, restarted, and have been experiencing this issue since.

LACT does control the fan successfully, just not correctly.

Did you take the screenshot with a curve at a different time than the snapshot? Because the snapshot has a different curve in the config (/etc/lact/config.yaml):

      curve:
        30: 0.0
        35: 0.2
        40: 0.4
        50: 0.6006192
        60: 0.7987616
        70: 1.0

Also, does the static speed setting work correctly?

Yeah it's from a different time. That config matches what it was set at the time. Ill have to check static speed later.

I see the same with a WX 3100, except that there is a 15% discrepancy instead of 20%.

I seem to have the same issue, using an RX6600XT (XFX Speedster SWFT 210 AMD Radeon RX 6600 Core). Edit: tried static speed settings: slider setting -> reported speed

Looks like the reported speed is also different when only one of two fans are running. I guess this is an edge case though.
