The above is not necessarily correct -- many of the chips supported by the lm(4) driver, on NetBSD, OpenBSD and DragonFly BSD, certainly do, in fact, implement a whole bunch of fan-controlling features; see http://sensors.cnst.su/fanctl/ for a sample BSD implementation of the fan controlling logic. >From the manual you've found, ftp://ftp.tyan.com/manuals/m_s2882d_100.pdf: >>>> ?

However, the above manual from Tyan doesn't appear to specify how exactly are the fans actually wired up (e.g., to which pins on which chip). Cheers, Constantine.
