Processor cooling ::
on the towers, how are the g4 processors [dual gig?] cooled? are they cooled via the traditional heatsink & fan method?
pictures?
just curious as to the method on the towers vs. the cube....
also, is it okay to put thermal paste along the WHOLE top of the cube's processor? how about the sonnet duet?

You only want to put a paper thin amount of paste on the raised portion of the CPU...the shiny square part.
Since when did Apple put fans on top of their heatsinks? My G4 400 is passively cooled...
See that huge stack of silver on the bottom-right? That's the heatsink. It's big.
See that fan right above it? That pushes air around the inside of the case. It's loud.

<strong>Not even paper thin. Should be even thinner than that...like nearly transparent. However, if the heatsink clamps on, it will probably squeeze out the proper amount of TI grease. Not sure how the G4's heatsink is mounted though.

Uh, heh...I know for a fact that it shouldn't be as thin as you describe. I don'tknow what kind of paper you use, but 'paper thin' seems to be a pretty good gauge. When I pop off the heatsink, I get those nice little peaks and valleys and it's evenly spread...and no excess goop squeezed onto the ceramic.
what size fan?
*thanks for hte pix links*
any decibel specs?

[quote]Stock processors and/or heatsinks with normal surface irregularities will require a layer 0.003" to 0.005 thick as shown below to fill the resultant gaps. (Equal to the thickness of about 1 sheet of standard weight paper.) Properly lapped heatsinks with mirror finishes will only require a translucent haze.<hr></blockquote>
Guess it depends on how nice the heatsink is.
BTW, so I guess the G4 does *not* have a CPU fan? I know it has a big case fan, but I don't see any CPU fan in those pictures...

my plan is to cool my cube with a papst 12db sleeve bearing fan
if 80mm...
panaflo & papst makes comparable cfm fans, with A LOT less decibels
