heat vs. speed
i've been noticing a lot of complaints about the loudness of current powermacs.
It seems that with faster processors, you get louder pm's. this is mostly due to the fans i assume, but isn't it also necessary to have these louder fans to keep the computer cool?
Would you sacrifice speed for noise produced? would you take a g4 500 over a dual 1 ghz just over the noise issue?
are people annoyed enough to change their purchasing decisions? would you instead get a 733 instead of 933?
is it possible to reduce the noise without sacrificing speed? could apple just use quieter fans?

Hell no I wouldn't take the dual 500 over the dual 1000!! <img src="graemlins/bugeye.gif" border="0" alt="[Skeptical]" />
I bought three potential replacements...
a Thermaltake rated at 21 CFM
a Papst rated at 33 CFM
a Sunon rated at 26.2 CFM
Now, I'm not going to use the Thermaltake at all since I don't think it blows enough air...I bought it just in case someone discovered the G4s really don't run that hot.
The Papst is what I tried first. It kept the heatsink very nicely cooled...it only got very-warm to the touch instead of very-very-hot to the touch. Too bad it sounded like a giant turbine.
I settled with the Sunon 26 CFM fan, which is basically the only 60x25mm Sunon fan better than the one Apple uses. It's not audibly louder than the old one to me.
I have yet to determine what brand the larger 120mm fan is, but I doubt it's a bad fan. It's certainly not the best fan out there, but it's probably not far from the top.
If anybody can find a decent quiet 60x25mm fan rated above 26 CFM, please reply.

Yes.
the reason i asked that was people were complaining about the noise with the ghz mac but not with a 500 powermac. would you rather have quiet and take a processor hit? that's the point i'm trying to make
<strong>I want a 1.2 GHz PowerMac for video editing, never mind how much damn noise it makes! My Imac stinks at it!</strong><hr></blockquote>
You can overclock the current one to 1.13GHz...
Losing one fan = Less noise
Actally the two big fans on the Slowsilver tower (side and on the power supply) aren't noisy. It's the one touching the CPU's heatsink making the noise.
For example, you could run water through the heat sink and then run it through a large, convection cooled radiator. Nearly silent with a good pump and fat hoses but takes up a lot of space and costs more than a fan.
I wonder if there couldn't be a better way to make the fan/heat sink work together? How about putting the fan inside the heatsink? Now you could use a noisier, more powerful fan and let the heatsink absorb the sound.
