A friend gave me an early-2009 17" MBP. It runs El Capitan and furthermore has the following specs: 2,66 GHz Core 2 Duo, 8 GB memory and a GeForce 9600M. He said it was unreliable in the past (not further specifying) but also said it was fine now, except that the fans would sometimes kick in really loudly. I created a new admin account, deleted the old one, installed iStat Menus, and saw that the CPU Core temperature is around 60 C, even when idle. Is this normal for this laptop? If not, what could be the further diagnosis and/or fix?
