My fan in my laptop runs off and on and an error message keeps popping up saying cooling error to turn my pc off for it to work but everytime i do that the message pops up again. I see my fan attempting to spin when the error message pops up. I usually run a desktop fan right next to my pc just in case it attempts to over heat. Not sure if i should get a cooling pad or a cooling fan. The cooling pad cost as much as the cooling fan i just dn't need to tear my pc apart if it will keep my pc cool. The lap top is 2 years old it's a Toshiba L855-s5240.
