With a Sonnet 1GHz G4 chip for my beige G3 showing up soon, along with a case transplant that I'm going to be doing, I'm going to need to be in the market for a fan/heatsink combination for the processor. What types of PC heatsink/fan combos will fit?

For example, is a Socket 478 heatsink/fan going to fit on a 1GHz G4 that's installed in a beige G3?

I haver the g4 1 ghz zif. It comes with two fans, and the heatsink permanantly mounted onto the card.

I have mine in a BnW, but recently put a g4 700 zif into a beige g3. the fit is tight, and you will need to attach a passthrough connector that comes with the chip between the Power Supply, and the mobo. If you are getting a new case, might need to know that. The cable is about 6 inches long. The g4 700 has the same mounted low profile heat sink(about 1/2 high), but just one fan. The cards draw power DIRECTLY from the power supply, so Sonnet sez that the royal voltage regulator issue is comepleatly bypassed. Would not want to find that one out in person however....

I can only imagine how they managed to get the heatsink permanently mounted to the chip; should be interesting. I'm imagining something like on my Radeon 7000...

Fortunately I don't have the Royal VR (checked that before I got the G4 366 that's currently sitting in there), so that shouldn't be an issue. Interesting that it draws power directly from the PSU, though. I don't think that the passthrough cable will be an issue with the new case, though; I'll be getting a new PSU anyways, so I can just make sure to get one with longer-than-normal molex cables if it becomes an issue.

So how's your experience been with the proc? Any weird issues crop up or is it smooth like butter? Smile

Thanks for the reply!
