Silenced my Mac
20 - 30 Minuten
3 year old MacBook started behaving spoilt making a large noise everytime it was running. The magnitude of the noise of that of a blender. Wife irritated - so had to be replaced at all costs.
Followed iFixIt instructions - so how dumb do I need to be to mess up the repair then? Huh? Still have a heated Mac though - haven't solved that.
Consider taking apart the fan assembly, blasting air to clean the components and seeing if that fixes it before ordering a replacement.
The Path of iFixit will lead to peace.
