Is there a way to check if the cooling fan of my iBook G4 12" is working or not? It was working fine a month ago. But now I cant hear it at all no matter what. I can feel that the machine is really hot especially at the bottom exactly under trackpad and it`s left side. I dont remember the fan running in the last 4 weeks. I m afraid that it is dead and it can lead to excessive heating and damage something I tried to check through a Dashboard widget iStat pro. It gives me following info:- CPU temp------------51 degrees Battery---------------33 degrees Memory/power------51 degrees Rear Enclosure Fan RPM -0 I would like to know if this is is normal or should I get it checked first. Any help/suggestions will be really appreciated.
