well, of course ;) there is a sensor somewhere because the machine will
switch the fan thru the three speeds it operates in, OFF, LOW, and HIGH

in the case of fans and monitoring their RPMs, they must be three wire fans
and be connected to a sensor that can be read by software... i use MBM
(MotherBoard Monitor) and have had no problems on supported boards, limited
success on unsupported boards and no success on the laptop in question...

i have even put three wire fans in power supplies and extended the leads so
that they reach one of the (generally) three fan connectors on the
motherboard... in at least one case, i used the AGP fan sensor for the
power supply fan readings since i've never had an AGP video card that had a
fan... the only "problem" i've really had has been lack of enough
fan sensors... generally there's only three or so on most motherboards and
i've not really found out how to tap into the SMB buss to add more sensors
that the sensor monitor chips allow for... i really only run into this on
some of my larger cases that allow for additional case fans in addition to
the one in the power supply... at least one case i have in operation right
now has four case fans in addition to the power supply fan and the CPU
fan... the motherboard in question is shy of connectors by 4 or 5 so i
can't monitor all the fans... no big deal, though, since the CPU temp can
also alert me to problems ;)
