I have a similar problem on my Acer Aspire 2920 with intel video card.
The fan runs permanently. I don't have installed tracker but I have
downgraded my intel driver to 2.4:
https://wiki.edubuntu.org/ReinhardTartler/X/RevertingIntelDriverTo2.4
because I didn't have the problem with Intrepid Ibex. Nothing worked.
The fan still runs permanently.
My harddisk gots a little bit too warm:
$ sudo hddtemp /dev/sda
/dev/sda: WDC WD3200BEVT-22ZCT0: 56°C
$ sudo acpi -t
Battery 0: Full, 100%
Thermal 0: ok, 43.0 degrees C
Thermal 1: ok, 45.0 degrees C
Top shows mainly xorg and firefox on the top:
