If the machine gets hot but the fan stays at minimum, one possible cause
is that the SMC has been switched to manual. If this was not done by
hand, it could have to do with switching between OSX and Ubuntu via
reboot. I have put this line in my /etc/rc.local to prevent any such
possibilities:

## make sure to use automatic fan control by default
echo 0 > /sys/devices/platform/applesmc.768/fan1_manual

Here is a thread about it:

Bug description:
Binary package hint: linux-image-2.6.27-1-generic

Testing Ubuntu 8.10 Alpha 4 64-Bit on a MacBook Pro rev. 3. Installing today's updates, the MacBook gets extremely hot and automatically goes into standby. This looks like an emergency standby caused by the EFI or something because it got overheated. Unless you put a metal plate or something under it, the fan runs on highest level at full power, which is not the usual.

Is there a tool you can see the CPU temperature with?
