After removing the bottom of the iMac G4, do I need to apply thermal paste to the heat sink? It is not mentioned in the guide, but I’ve seen youtube videos saying it needs it. I already closed it, but I am wondering if I need to open it up again and apply the paste. Removing Bottom of iMac G4 15" 700 MHz EMC 1873 Thanks in advance! Willy.
If you didn’t remove or touch the heatsink you do not need to re-apply thermal paste. However, due to the age of this machine re-applying thermal paste may help with some of the thermal woes.
