    • Before you reassemble the computer, double check that your new hard drive has the same jumper configuration as the old one. This ensures the IDE "Master-Slave" protocol isn't interrupted. Some systems do not require this, but if you are having issues booting up afterwards with the storage or the disc drive, this could be the source of the problem.

    • Take out the two T-15 screws that hold the fan brackets to the chassis.

We need to show an action shot for step 8 of the REmove Drive Carrier Assembly

Courtney - 回复

I don't see why it would be necessary... ??

Nicolas Zbinden -

I would like to add; That you may need some thermal past as there is a heat sink that splits in two when you remove the bottom.

anyone have a link for an adapter i can use to make any regular pc fan work in the imac g4? i was looking at a blue LED one on amazon and a guy said in the comments it would work but it needed an adapter but I can’t seem to find the correct one! plz help, thanks!

What size is the fan? Regular 3 pin connector?

Thomas Grondowy - 回复

I'm not exactly sure because I don't have a G4 yet but according to the model name FBL09A12V it's probably a 92mm fan.

The connector seems to be a usual 3-pin but it's a "female" socket while almost every other fan usually has the "male" plug.

For a custom fan you would need an adapter cable with that male plug on each end or a so-called "gender changer", couldn't find one with a quick search so i'd recommend to get a simple 3-pin fan extension cable, cut off in the middle and then take the cable part with the socket then cut off the plug from the fan you want to put into the iMac and solder the three wires together (don't forget the heat shrink tubes).
