Unfortunately these don't work, or rather they don't report the fan speed. (In conky, for example, if I add lines to the config file to report the CPU temp, fan speed, and fan state, I only get the CPU temp, with the other lines empty.) > > Can I control the fan? > > I don't know.

Right; my intention wasn't to control the fan manually for regular use, but rather to try to turn the fan on high so that I can see if there is, in fact, a whooshing sound that would indicate the fan has been turned on high. I'm running FreeBSD 5.4-STABLE, by the way; I acknowledge that there is the acpi_ibm.ko thing under 6.x, and perhaps this would be helpful. However I can't even think about upgrading because compiling almost anything causes the computer to crash from overheating :-/ Jesse Sheidlower _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
