Well I'm on a roll so I was checking the CPU temperature an older MBP 15" mid 2010. Under mild load the fans aren't really annoying but I noticed that the CPU temps (according to MacsFanControl) are 80+ deg C under mild load and 60+ deg C idling. The tool also reports that the left fan is not rotating, it's dead - or is that an error? Is either of this (temp and the left fan not rotating) normal? Enough justification to take the thing apart and replace the CPU paste, which worked so well with my 2008 MB?
