    Greetings All.

    I'm a reasonably experienced PC repairman that has been hired to determine what is wrong with an iMac G5. I've disassembled it and have found several problems, and need to make a report to my customer. To this end, I need to be able to describe what the 3 large chips on the Logic Board of the G5 are. I assume the chip with the large copper heat pipes and fan is the "CPU", but do not know if that is the correct terminolgoy for an iMac.

    Also, the other 2 chips. One has a rectangular heat sink that is visible when the viewscreen is removed, and the other is square and can only be seen after the logic board is removed.

    I'll attach a photo. Thanks in advance.

    CPU or processor are the correct terms for Macs CPU's. The ATI chip is the GPU or video chip. The other one is probably the north bridge equivalent chip. One thing to check on the iMac's board and power supply are bad capacitors. Those are notorious for failing in G5 iMacs.
