Hi and thank you for that information.
It could be the main board that has the problem but in almost every instance when this happens the thermal element is to blame, it is a cheap easy to replace part and I will help you all the way if you are handy and have some basic hand tools;-)
It turns the fan on when it thinks the temp is still high, and shuts it off when it has cooled.
It has only two wire clips to press on and pull off so no soldering is required ;-)
The best place to get that part (the fan thermal cut off) is: http://www.espares.co.uk/
I would call them to order this part as they will ship that to you the same day you call.
