I just purchased a primary and secondary fan replacement from this site for my Ti G4 PB 1GHZ. (Although it looks like I got the last one. After I purchased it, the status went to "out of stock").
Anyway, both fans "details" pages noted that I would need the Torx 8 tool and the G4 Ti 1GHZ take-apart guide.
After purchasing all 4 items, I downloaded the guide and skimmed through and did a text search for "fan".
I do not see any instructions on taking out/replacing either of the fans. Does that information ship with the fans? Did I make a mistake and buy a guide that won't help me?
