Bug Description
I have Ubuntu 12.04.1 LTS installed on my Asus K53SM alongside Windows 7. Ubuntu has been installed on a seperate partition and I am using the GRUB loader for booting.
The CPU fan on my laptop is constantly at a very high speed irrespective of whether I'm running any CPU intensive applications or not. The CPU's reported temperature is 42 degrees centigrade (room temp is 28 degrees). The air being ejected out of the system is cold and not warm enough to warrant a high fan speed.
I have installed bumblebee to ensure that my Nvidia card is not constantly running and I ensured that it is fully updated to the latest version. All the reported updates have also been installed on Ubuntu.
WORKAROUND: Switching to the Nvidia proprietary drivers seems to have drastically reduced the fan throttling.

I think it's the USB card reader (Realtek), and in particular the kernel module rts5139, which is still in staging.
Try to do, as root, "modprobe -r rts5139" and see if that fixes it.
(obviously your card reader will stop working).
