    I have a 2011 13" macbook pro that I purchased off of Kijiji. The person said that there was water damage. I opened it up and found a couple of spots that were corroded and I cleaned them with alcohol. The laptop works flawlessly with one problem. The fan is running full speed. Obviously something wrong with the sensor. Is it possible to connect a small resistor into the power feeding the fan to slow it down?

    If the sensor isn't faulty and your fan is spinning up without increased heat, try resetting the SMC.

    Didn't work and I have installed monitoring programs which show the fan rpm at 0
