Overheating attributed to Freebsd --sysctl variables not available--

[nw1]

The problem can be viewed @:
http://69.3.136.141/freebsd/installation/sysctl_variables_missing

Basically, the machine is overheating (I believe) because the cpu's aren't cycling down.
Previously I was able to cycle the processors down with the following sysctl variables:

machdep.apm_suspend_delay:
machdep.apm_standby_delay:

however, for some reason those variables currently, aren't any where to be found by the
up_and_running system.  Please use the hyperlink above for details.

Thanks for reading.  All feedback is welcome.
