Noiseless (silent) cooling

[dmkf]

Hello there! First of all, aquamac, you made great mods with MDD and all other machines.
I recently made a couple of conversions as well, started with G3 B&W for a many terabyte fileserver, then i eventually found a dead PM G5 1.6 which i used to make my own hackintosh. And now i have bought back (that's another story) my precious MDD 1.25 UP 2003. I though i can convert it to a some kind of hackintosh too, but it seems to be nearly impossible. So i gave up and deciced to trade it for QuickSilver, but no one seem to have one around in my city. So i'm getting ready to clean it up and make it another big storage (i have 2x500Gb HDD in AcomData boxes, so move them into MDD).

I read this forums, googled, read xlr8 and other boards... But i still have no REAL idea what i need to get to make MDD silent or at least very low noise. This is gorgeous machine you know. The main thing i figured out is the famous PSU 60mm fans. There are some fans on market that suggested to make a good replacement for stock ones. But the problem is i have nothing like that around. Okay, i'm in St. Petersburg, Russia. Most of the ebay sellers dont ship here or do at insane rates (see, like $30 for a $22 fan or like that). So before i make any purchase i need a really good think.
Does anyone know, what airflow does need MDD PSU? I started to think about a 120mm fan with a duct into the PSU. Any suggestions here?
Also i'm looking into a good heatsink for the single 1.25GHz CPU board. Aquamac's zalman mod is cool, but that eats lot of space and requires to detach backside hdd bay...
I'm okay with main 120mm fan, i have a spare for it, low RPM, low noise (they are wide available here), i even tried G5 92mm CPU fan and it runs fine with almost no noise having nice airflow.

The main thing about my machine - i dont want hurt it too much, want to keep all the hard drive bays (to fill).

Anyone here may sell me good 60mm fans and CPU heatsink at a reasonable rate, please? Or trade for some Powerbook G3/G5 parts or anything. And yes I can paypal.

And here are some pics of my mods

Thanks in advance!

Hi dmkf,

Welcome to aquamac forums, that is one very clean mod:



Especially like the pic above, it shows off the lack of spaghetti!

I was also thinking of a MDD hackintosh, but you are looking at a BTX motherboard. Intel make one that is quite nice:



This board would involve quite a bit of surgery around the processor as there is the CD drives/HDD's in the way in a MDD.

The other thing with the MDD case is to remove as much metal as you can to let air circulate better. Sorry, I don't have any 60mm fans at the moment. Your best bet maybe to go down the 120 mm or 92 mm route with a baffle and duct.

Thanks, it's even cleaner now, i solder off most of the ports on the mobo and since i had dead G5 logic board, i took its ports on the plate off and was going to make it back to the case, you can see prelimary work here:



But this never happened, i felt so hard to desolder ports so i gave up and left ethernet and 4 USB ports. So i sawed off a little square hole in the back around airport/bluetooth antenna outs. I needed ethernet badly.
The hardest challange about this mod was the heatsink. This very beast:



took me like 3 hours in a row to take it off.

Thanks for the point! I didnt know about BTX, heard of it of course but never dug any info. Can you please tell me what this very mobo partnumber is? I'm going to give it a try, found some cheap BTXes in local stores but the all seems to be P4/Pentium D only which is not good for hackintosh you know...

I see. Thank you anyway. I tried yesterday to make a prelimary duct, but it seems to be too big for the MDD case with 120mm fan. I'll try with 92mm one.
Aquamac, do you know about the PSU sensors? Verax fan installation guide mention it, i never knew about that before...

Ah, nevermind about mobo pn, i see it now, it's DQ965CO. Thanks anyway!

Why haven't you glued the full panel onto the back side of the case after having soldered the ports to cables connected to the mobo ? That's what I want to do if I find a dead mobo for my case.

bb, that's what i was GOING to do. But it was so much effort (for me at least) to take off (desolder) ASUS ports, so i gave up. Maybe i'll do this one day. I also worry too much about Gigabit LAN... I couldnt find info it it's okay to solder connectors. I know that twisted pairs very sensitive to any damages and soldering absolutely unacceptable. But i dont really know if that applies to female mobo connector.
I also glued the soldered wires, there are lot of them (25 maybe) and desoldering was so difficult so i dont really know if i can solder new wires back. The mobo seems to be like 8 layers, very hard to get pins off... It also doesnt fit very well in the part where G5's ethernet is...

What I mean is solder cables onto the G5 ports board on one side and on the other plug the cables onto the Asus mobo without desolder anything.

It's way too tight and short space there, unfortunately...

[B B]

yes, that's right I forgot that you need to put the mobo more on the left side inside the case as here :



with as result :



a hackintosh with a real G5 back case.

This is way to complicated AND not good for me. I saw that, yeah, i think i saw every single G5 mod while was looking for info lol
