I recommend that you label all connectors to make them easier to reconnect without error. I also suggest you watch the video guide on YouTube so you can read important information I added under the video there in its text description -- open the video on YouTube, look beneath the video and click on "SHOW MORE" to see all the notes. | | The basic procedure shown in my video has been successfully performed by others on model year 2010, & 2011 andiMacs; however, the bake CANNOT be performed on late 2012 and newer “tapered edge” iMacs because their video card GPU is soldered to the main board. | | | I also made a SECOND VIDEO showing my second bake, which provides even more useful information such as the thermal paste I successfully used and how to apply it: https://youtu.be/6BJGLFCigdA |
