This was not true of the Digital Audios, for example, as each processor type required its own fan module type. > The processor daugther card and the heatsink are a unit when > assembled, but > the original apple processor cards are build so that you need to > install the > processor first, and then you are able to place the heatsink on it > with the > latches engaged. In a Quicksilver, as in a Digital Audio, the heatsink must meet several requirements: 1) the heat transfer pad must be directly above the processor die or dies, and 2) the cooling fins must accommodate the VRM (voltage regulator module) choke coil, and any other components which are above the seating plane of the processor. This means that a DA or QS processor should never be bought (nor sold) without the heatsink with which it originally came. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
