Then maybe you should just use Arctic Silver 5 like most of us do.

I don't know what you read but from the little bit I did read, you put the indigo extreme between the heatsink and cpu just like you would AS5. Did you read the entire article?

I think they are assuming you already have an OS installed. Main reason I say that is, it says boot the computer and open a monitoring program. You couldn't do that if the OS wasn't already installed. After you install Indigo Extreme to the cpu, then you intall your OS. Another reason is because the instructions tell you to remove the old grease before installing the Indigo Extreme.
