My laptop (Compaq 6720s, bought in 2008) behaves also like this. After "waking up" the fan is turning on full speed with raring. With quantal it behaves as it should.
I tried all kinds of things to cure it (GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=linux" etc). Nothing worked. But the file /etc/pm/sleep.d/99fancontrol.sh as mentioned by filip (bandit-s-fw) on 2013-02-09 above works 100%.
Thank you very much.
Every time there is a new linux kernel in the updates, I make the file /etc/pm/sleep.d/99fancontrol.sh non-executabele. Then I bring the laptop in ram-sleep and wake it up again to test if the problem still is there. Until now I need to make /etc/pm/sleep.d/99fancontrol.sh executable again very quickly because the fan is going wildly.

Ofcource it would be even better when this tweak wasn't needed.
