which models came with copper heatsink?
ive never seen one

which models came with copper heatsink?

Apparently all 1.42 MDD (FW800)

What I dont get is why DieHard says 1.25 had thick as my 866 ?

I thought first ones had thick, later thin (stainless steel), and finally copper.

It could be that there are various 1.25 models, older ones and new ones.


There are 4 models that can be called MDD 1.25...

i meant in person.. i have not seen one in any of the mdds that i have found....
for sale.. available..
they always have the aluminum ones
i think the copper ones were not used for that long and that they are alot more rare and hard to find
to buy
i have never seen a 1.42 fw800 in person either
but here is one for sale
http://www.ebay.com/itm/Apple-PowerMac-G4-M8841LL-A-1-42GHZ-15-DISPLAY-10-4-OS-9-2-MAXED-FREE-SHIP-/151514984402?pt=Apple_Desktops&hash=item2346ff2fd2
so i guess u are right

but yes my fans are set up exactly like the above pic..
one pushing out and one pulling in
but this is a better job then i did.. i had 80mm fan
and i had to cut the frame of the fan to make it fit
it is a total hackjob what i did lol
i think it would be better to use 60mm fan because they would fit better

From what I have observed...

Most of the The 2002 Dual 1.25 Ghz. Have Thick Aluminum

Most of the MDD 2003 Single 1.25 Ghz. have Thin Aluminum

Thin Aluminium heatsinks (like steel) degrade its performance with time (Gas filled go heaven/hell) while thick ones performs like first day! You have to clean it but those are ethernal!

Glad the thick ones performs better than thin ones! I was thinking the opposite!

I never measured temps, but I trust the MacTron Lab

Any know an 3rd part. MDD cooler. Cooler Master, Nox, etc or a kit to adapt others?

Extremely Cool... (Temperature wise)... but adding more fan Noise would make me freak

Looks like he de-soldered two RAM slots as well. Not ideal

[DieHard]

Great if you are Going SATA... but looses Ulta-DMA PATA/IDE 100 controller, no room for Hard drive there, Also Extra Fan on Back of case probably adds Noise also

[supernova777]

actually no he didnt if u read his site im pretty sure he explains that mdd was some educational or special model of some sort .. it came like that- if u look closer theres no reason to have to remove ram slots frm teh board he could have just removed the ram ifthere was a physical obstructon but there was not

im personaly surprised we havent seen more people do custom heatsink cooling solutions like those last 2 that pro tools le guy posted

Not exactly true. MDD can support 1 Gig DDR memory sticks. With 2 you achieve Maximmum.
It is a pain in the ass to pull them off but at the Japamac/bdaqua/MacTron  proof of concept  level, the limit is nowhere.

MDDs are flexible. If you want room for the heatsink you take 2 there. If you want room for the AGP with modern double height fan, you can choose those other...

Yes, you loose room. But there out are dozens of 775/1156 heatsinks smallers than stock heatsink... The shit is to adapt them. Most mods made by Japamac/bdaqua/MacTron involves tools (Dremmel/saws/etc) that most of us don't have.

Even if you loose that place, you can still wire the IDE 100 controller to any other place, like over the CD bays or instead of the IDE 66 ones or even outside.

For sure 3 fans at full power sound louder than the original one.I would had changed that fan inside for a thin one between the plastic from outside and the metal cage as I ve seen elsewhere. Or cut the 2 bay to make it 1 bay.

We will discuss this further and make a new thread... some MDD boards DO NOT take 1 GB RAM sticks at all... they see them at 512MB and they fail extended tests.  I have learned to use 512 MB quality modules over the years

those pc style cpu coolers arent as loud as u would think..
compared to the crap apple put in mdd's to begin with

Because the stock heatsinks works. Why fix something that isn't broken?

[Protools5LEGuy]

Yes, they work but rely on a LOUD central fan for all the system. That fan is someway far to the CPU heatsink. That make fan work at high RPM, (In case OS9/MDD hardware control that fan, that works full throttle on OS9) .   MDDs are LOUD even changing all fans (PSU+BOX)

[Metrophage]

Because the stock heatsinks works. Why fix something that isn't broken?

The stock setup is not very efficient. I had a MDD basically cook itself after a few years with the stock cooling. For a single-processor system and/or one that isn't maxed out, it should be adequate. Consider though that since they include three ATA controllers and slots for five cards, that some people might actually use those. Once you've got an optical drive, four hard drives, and a few full-length AGP and/or PCI cards that this drastically affects the airflow of the case. This is what they addressed with the much larger G5 cases by breaking the space into distinct zones rather than expecting  a central fan / air conduit to handle everything.

One nice solution as IIRC DieHard mentioned is to use SSD drives, since they run so much cooler. But this would be something of an investment for me, since I have a big box of viable drives already.

My approach was to re-case the MDD, but I haven't completed it yet. I am running a FW800 stock now, and making a point to take it easy on this one in the meanwhile. My other MDD is in a SwordM case. What I did was disassemble a MDD case and isolate only the logic board mounting and port section of the back, which I then bolted into the SwordM. This is a much larger case with much more air flow than the MDD case. From there I was trying to implement a modest liquid cooling setup when I ran out of funds for the meanwhile. I hope to resume working on this system sometime.
