[opensuse] Fans on Full Speed or not at all (Leap 42.2 Fresh install)

Oldish (ok, ancient) laptop, Dell Insperion 9400 with new install onto SSD. Since the update of last Monday, fans come on full speed even at low-ish temps of 34C. Fans are either full speed or none at all. When I first installed 42.2 I don't remember this being this way. My fans have several intermediate speeds. What changed, and how can I get back to stepped and managed fan speeds? What package controls this these days? -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
