Ok so I just bought a used 2009 MP 15 inch. I noticed that it was getting pretty hot even the charger while operating so i downloaded istat to get a reading of the fan and it was saying 0rpm. So I downloaded this software to control fan speeds. My computer went from 88°c to 69°c so i assume the program is working. I unplugged my charger also so i dont know if that could be the key factor also. Any who Even tho my temperatures are dropping my fan speeds is still reading 0 for some reason. The mac is still warm to touch but not as hot as before. Is that normal for macpro's? even while only surfing the web? my pc laptop never got hot or warm for the matter. So with istat not recording fan speeds but everything else could that mean the fan isnt working even tho the mac did cool down some after using the fan program? may I add that the fan speed program i used that monitors the fan is also showing 000 rpm for the fan. Thanks and id appreciate you guys input.
