My fans sometimes never seem to kick on, no matter how hot my computer gets. I am wondering if this could be tlp/acpid related? Perhaps not, but it happens mostly when I am plugged in to a power source. Disconnecting the power source doesn't seem to activate the fans, but it cools my computer down about 20F in 30 seconds.

While plugged in, listening to music, and charging my iphone.. about 30% cpu load and 40% memory load ( the temp would keep climbing but im hesitant to let it, ive let it ride to 205F to see if the fans would kick on, but nothing):

unplug, same load, about 45 seconds later (and dropping):

any help or thoughts? I did at one point install smcfanctl or one of those variants, but have since removed it.

edit: smcfancontrol will autocomplete in the terminal window, but there doesnt seem to be anything to remove or a man page, so i am confused as to exactly what this is

$ which smcfancontrol 
/usr/local/sbin/smcfancontrol

edit again: after allowing my computer to hover at about 180/200F by unplugging and plugging back in the power source repeatedly the fan has kicked on to 4500rpm, but is only cooling the CPU to about 170F at this speed.
