When using my laptop its always hot…..what do I do??
As Dan said it would help to know your exact machine but the 3,1 designation was used in the 2007 range. I’d open it up remove the fans, blow them out and the vents are prone to clogging. It’s also about time to replace the thermal paste. After we know your exact machine we can get you to the correct guides to show you how to do this. Update use these guides, close enough: MacBook Pro 15" Core 2 Duo Models A1226 and A1260 Left Fan Replacement MacBook Pro 15" Core 2 Duo Models A1226 and A1260 Right Fan Replacement MacBook Pro 15" Core 2 Duo Models A1226 and A1260 Heat Sink Replacement
