OMG! Ubuntu! shows you how to use PSensor to monitor the hardware temperature in Ubuntu

My graphics card fan is bust.

Well, I say bust but what I actually mean is that I disconnected the fan because it was so freaking loud! I do intend to buy a replacement cooler for it shortly, but in the mean time Psensor allows me to keep an eye on its temperature over a given period with the data recorded and presented in graph form for easy digestion.
