Yeah, but on my laptop, the fans are controlled only by temperature. 
According to "acpi", the fans can be in 3 states: active, passive, and
"ok" - these are cooling modes.  It seems when I boot, Everything
starts in "ok" mode and the fans are real quiet.  When I hit a
temperature threshold (~125-130F) it clicks on to "active" and never
leaves active until I reboot.... it's kind of annoying, but I can live
with it
