Hi everyone, The fan of my mbp 15" mid 2009 runs at 6000rpm from the moment I push the power button. When I check istat pro, I only see 1 sensor = the one from the hard drive this made me run an hardware test, which came up with a fault code -> googled it and it was linked to a problem with the thermal sensors Can anyone help me finding the thermal sensors ?? In the earlier models the heat sensors were attached to the heat sink or case. In my model I think they are somewhere on the logic board? I just don't know where to find them.. please help! second question: is there a possibility to replace them? thanks!!!!
