The Logic Off Topic list

I'm looking for a low noise case for my soon to receive new Apple G4 
dual P.
Is this as simple as with an PC?

Sorry for my OT question.

Regards,

Maarten

This is the list for politics and abuse.  How dare you ask an 
unloaded question.

Actually it *is* a loaded and sensitive question so I will answer:

No it is not as simple as it is with a PC.  A lot of people are 
complaining bitterly about the noise of the cheese grater Macs and 
several have been driven so far as to build machine rooms for it. 
AFAIK Macs want their own power supply and the power supply houses 
the fan.  In the new Macs the fan is actively controlled by the OS 
and if your are running OS 9.xxx the fan is permanently in "loud as 
hell" mode.

Now the part where the PC people can begin the abuse of Apple and the 
people who buy their stuff.

I'm sorry for that. ;-)

So, you don't know of a case available for the Mac? I once was 
pressent at a Digidesign presentation and they had a Mac Dual P in a 
19" case, which was very quiet?!

 From today's macfixit.com

Hans Koenig offers a hardware modification that dramatically reduces 
the temperature (and therefore loud fan operation) experienced when 
running Mac OS 9 on a Power Mac G4 Mirrored Drive Door system.

The hardware modification could void Apple's warranty, and should be 
applied with extreme caution, if at all:

"Make (or get someone to make) a connector adapter: fan socket to 
standard hard drive power connector. Connect the fan power lead to 
the 5V HD lead (not the 12 V) and bridge the free fan connector pins 
at the mother board with a 20 ohm 10 watt (18 watt in the picture) 
resistor. (From fan data: 12V 600 ma P= IV = 7.2W)) Plug the fan 
socket into the adapter and the HD socket into one of the available 
free hard drive connectors inside the Mac. The big fan will now run 
constantly but the 5V connection runs it at much reduced speed.

"The resistor is necessary because the heat sensing circuit needs to 
see a load when it decides to supply power to the fan. If the load is 
not there the circuit unceremoniously shuts off the Mac, a nice 
safety feature, Apple! This resistor is big and needs to be mounted 
to the metal side wall of the Mac.

"This Mac running OS 9.2.2 has been exercised for some four days now 
working with Netscape, Canvas, Excel and GraphicConverter open and 
doing their thing: Surfing, manipulating photographs, doing 
statistics pretty much constantly. No temperature rise to note during 
these operations."
