I like the G5 because of it's efficiency and speed and processor design. me second is the G4, then the PowerPC 601. -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

And the reason Apple never put a G5 in a notebook or Mac Mini is because the chassis is too constrained for adequate cooling, that and battery life in a notebook would be abysmal. Given how many fans there are in a G5 Power Mac I would expect that the G5 iMac would have more than one fan too.

I imagine that it CAN be done, the question is would it be practical? And that answer would be no. The heatsinks are certainly different, and likely the fan too. Removing all that noise would result in an overheated G5, unless you built your own liquid cooling system somehow. But that too is going to be impractical. The G5s used in Apple desktops is a relitively inefficient CPU, it uses a lot of electricity and creates a lot of heat. To deal with the heat you need a lot of air flow, which is where the high noise level comes from. The G5 Power Macs used many fans running at low rpm to keep the noise down, but in the iMac there isn't room to do that so the fan(s) have to run at higher rpm. Also the Power Mac as a less restrictive air flow path than the iMac, which helps cooling and creates less noise.

Re: iMac noise
When I ran my iMac G5 ran at the "automatic" option, it felt like I was running a crawling 1.5Ghz G4. Now that I turned on the "Best" option, I don't care if it makes too much noise, as long as it isn't too loud, and to make sure it doesn't overheat. I don't want that capacitor problem with my Rev A iMac G5. With this option i set it to, It feels as if leopard has started to run as fast as snow leopard does. There should be an option for iMac G4 computers to change their clock speed, because i have one iMac G4 800 that has no internal HDD or DVD drive because the IDE bus FAILED. I boot off of a firewire drive, and it works fine. If i can overclock this to 1.1GHz, they say that the machine will produce too much heat that it might set on fire, and if i overclock it to 1Ghz it will be a little warm. I am planning on overclocking it to 1.15GHz, because without the HDD and DVD drive in there, I have room for a bunch of fans! Maybe even a small water-cooled system. If it works out, I might overclock it to 1.2Ghz, but that might produce so much heat that only a water-cooled system will work with it. I can overclock my 1.25Ghz iMac G4 to 1.67Ghz, but I need a giant fan (or 2) on the logic board, and i will need to take out the HDD and CD drive. I wonder how you overclock a flower pot... -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

I think the half sphere makes a chamber that resonates the sound, or maybe it's the air flow restrictions.
