So I don't know much about thermal pads and pastes beside to keep a computer from overheating a lot, they should be replaced every 5 years. Well, my iBook G4 hasn't ever had the paste or pads replaced, so I thought it might be worth it sometime. From what I've read on other sites, thermal paste is easier to apply, but I think my iBook G4 has thermal pads. I don't really know the difference, so can someone help me here? Apple must have used pads for a reason, but should I buy new pads, or new paste? Also, did Apple use thermal pads because the heatsink is so close to the processor (I mean really close)?
