Original GitHub issue: https://github.com/hirschmann/nbfc/issues/1049

Device: Lenovo T14 Gen 1 (AMD)

nbfc is able to detect the temp sensor and fan speed it seems, but setting the fan speed manually (say, at 100%) makes the fan pulse (higher rpm then lower rpm, every few seconds)

Tried using T480 and T540p profile.

Update: I can get this working with tpfancontrol v0.62 for some strange reason. Not sure how to grab the correct pin information to plug it into nbfc.

@Snuupy I have the same issue with an e595.
maybe there is a write to an register needed to stop automatic controlling.
