Dell Studio 15 - Fan/Overheating Problem

[Reece]

Hi there!
I have a bit of a problem, the fan on my studio doesn't seem to work at all any more, speedfan lists core temps going from room temp to 80 degrees C within 5 minutes of startup.
It keeps constantly crashing, and turns off completely then wont start up again until it has cooled down.
Its in a well ventilated area, on my desk with nothing else.
Any help/fixes would be very much appreciated.

Make sure that:

- the fan is running
- that the fan intakes and vents are unobstructed
- that the laptop is resting on a flat surface

Also, try cleaning out the insides for dust using a can of compressed air and a vacuum cleaner.
