is there a way to take the fan and heatsink from a core duo iMac to an
iMac G5 to remove all of that noise?
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.
