Oi's MDD

[Orizence]

I would also love to see the results, im thinking of picking up a MDD for running some os9 apps

 

[oi!]

Maybe check out my solution to the noisy PS fans in this thread, (starts at post #11).
Works really well and quiet with the large 120mm fan running at a reduced speed.

Looks like a good idea, I have some thoughts about a duct already.

 

[oi!]

Fitting the 60mm Fractal design fan, but the 80mm doesn't fit. I must have measured wrong!
Second 60mm now on order.

Will post pics L8R.
Also, I'll revisit my thoughts on that 120 mm PSU fan duct.


On a side note, this looked interesting (but expensive)...

Well, it's now later, so here are the pics.
Fan ready for second attempt at mounting...

Second attempt at mounting the 120mm fan...
View attachment 617420
(and another pin tail superglued on to prevent vibration)

Fractal Design 60mm fan, almost fits. But between the back of a screw hole and a rivet it didn't quite, so out came the dremel for some more modding...
View attachment 617422

Now screwed into place...
(I took the rear plastic panel off the door, I found removing the lower rear side panel screw made this do-able, with some jiggling it came off without snapping anything!)
View attachment 617424
(I managed 3 screws, a guy on youtube (ItsMyNaturalColour) say's only 2 are possible - so I guess that's 1 to me then?)View attachment 617423


Also, a while back, I spotted a pair of Sunon PMD1206PMB3-A 60MM (from a Dell Optiplex) for not much money. So I bought them...
View attachment 617421


They're 60 x 60 x 38mm, 5.2W 0.43A / 12V(6-13.8V), double ball bearing, 5 blade fan.
41.5 cfm (70.51m3/h), static pressure 13.45mm H2O @ 6000rpm, and 47dBA!
I was thinking of running these on 6v, or even 5v if I can persuade them to run at that.
Also, they came with 4 free sound insulation pins each (which is good) and 4 wires at the plug (which isn't).
This is the baby brother of the Sunon PMD1206PMB1-A, which you can buy from eBay, eg...
http://www.ebay.com/itm/1-PC-SUNON-...218200?hash=item28048070d8:g:rCEAAOSwPcVVuMEd





On a side note, I found this, pretty stylish for a PC case I thought. In a very Blade Runner kind of way...
http://www.ebay.co.uk/itm/Thermalta...375830?hash=item4af57fd696:g:o9wAAOSwDN1USvG4

 

[oi!]

OK, I'm now running on Hush Puppy.
I have the SilenX IXP-76-14 120mm with 1 x Fractal Design 60mm fan and the hushed PSU.
It is just so much quieter!
And damn that hard drive sounds noisy now!
Watching the CPU temp like a hawk, it's still warming up. 42.1C and climbing. If it gets above 59.0C I'm shutting it down.
[doublepost=1455998066][/doublepost]Well, that was nice while it lasted!
Now back on Noise Monster after Hush Puppy hung at a CPU temp of 46.6C.
I was loading it up to see how the temp went - Photoshop, to work on a request I've had.
Not sure why it hung, PSU was warm to the touch, but not hot. CPU heatsink the same.
In a word... disappointing.


Scythe Ultra Kaze now on order.
Also a VGA PCI graphics card, so I'll be able to flash a PC AGP card.

 

[oi!]

If the Sunon PMD1206PMB1-A 60MM fan is not sufficient for your requirements, I may have found an alternative for you.
The PFC0612DE is 60 x 60 x 38mm, 16.8 W 1.68A / 12V(10.8-13.2V), double ball bearing, 7 blade fan from everybody's favorite fan manufacturer... Delta Electronics.
67.85 cfm (115.28m3/h), static pressure 54.1 mm H2O @ 12000rpm, and 61.5dBA!!!
Also, they came with 4 wires at the plug (similar but not exactly the same as the Sunon PMD1206PMB1-A).
You can buy from eBay for fairly cheap...

OK, so lets take a looky at that 120mm fan PSU duct.
I want as smooth an airflow as I can achieve and I'm not afraid to break out the dremel to get it.
The fan is a circle about 114mm in diameter. The PSU is a rectangle about 121mm by 61mm.
I want a nice smooth transition, so here's a series of sections...
(created in Illustrator)
View attachment 617615

I printed this out, cut some board to the shapes, and stacked neatly to show the smooth-ish transition...
(roughly sawn, trimmed and sanded to shape. Yes, it is a bit rough!)
View attachment 617610

Next, arranging them into an elbow!

 

[oi!]

Elbow!

Next, trial fit (when the glue dries).

 

[oi!]

Can't trial fit, this was made for a modded PSU housing.


On a side note, these pics ain't all that great quality, used digital camera now ordered from eBay.

 

[oi!]

Both the Scythe Ultra Kaze 120mm and Fractal Design 60mm fans have arrived in the mail today. I'll install them soon, but not tonight.

 

[oi!]

Both the Scythe Ultra Kaze 120mm and Fractal Design 60mm fans are now installed, pics and a trial run later.

I had plugged the SilenX 120mm fan into a molex, could this have caused it to hang?




On a side note, a daft idea. I spotted a faulty Mac Pro on eBay for not much money recently, which got me wondering wondering. If I cut a large hole in the middle shelf, positioned the cpu heatsink right up near the ceiling of this case, could I get the AGP and PCI slots to line up with the rack in the back of the case?
I found (on wikipedia's Mac Pro page) an image showing the rear of a G5 and a Mac Pro side by side for comparison, this gave me something to measure against on my (unused) G5. They don't line up, they're about 2 slots too high up the case, with some thought, imagination and sacrificing a slot entry (my SATA card has no external ports) I think I can see how I could get this to work. Not sure how the case's PCI rack would fit with the RAM sticks though. The bigger case would allow me to use a full G5 water cooling kit, suitably modified. This would also give huge amounts of case space, for maybe a much modified and silent PSU. With SATA HD's, I have six IDE drives I could turn over to DVD drives, with some front side case mods for extra drive doors.
I'm not planning on actually building this, it was just my overactive imagination running wild in a very bored moment.

 

[eyoungren]

So, I've been following you on this. Sounds like you have some intricate work.

I don't have an MDD, but here is what I did with my QS. The first few pics are from a year and a half ago and the final result is the last two pics with more internal stuff removed.

Maybe it might help you in some way?

The thing about the MDD is it's cramped in there and pretty much unique internally too, the CPU is where the PCI slots should be, the PSU is mounted on the side high up, the optical drives are on a shelf dead center in the case. The two pairs of HD's are on the side mounted vertically below the PSU right next to the CPU heatsink. Or horizontally, in the way of the CPU heatsink airflow obstructing it nicely. Odd all round!

Nice pics, btw, looks like a really nice system you have there, and with dual 1.8Ghz's, way more powerful than mine!!! Do you have any dust issues with the bottom mounted fan?



On a side note, now running on Hush Puppy again, CPU temp is climbing, at 49.1C presently.
So far, so good.
Apart from the HD noise, it's pretty good, I can still hear a fan, but I'll work on that. TBH, there's just no real comparison between this and Noise Monster!


Pic's soon, I promise.
[doublepost=1456439173][/doublepost]Hung again, but am persisting with Hush Puppy this time, oddly, both times the temperature reported as falling a degree or 2 before it hung.

Any thoughts anyone?

(now at 58.9C)
[doublepost=1456439496][/doublepost]Fan speeded up masively as it passed 59C, temp fell and fan speed slowed gradually, I never noticed that work so well with the delta.
Worrying, as I'm hardly working it!

I would argue that the Quicksilver's internal is much more cramped than the MDD. You are also seeing things after I pulled out the ZIP drive cage, the internal speaker and it's shield, the HDD cage and the two bottom drive trays. I also removed the PCI card stabilizer frame on the compartment door and the metal guide for the Airport card (this Mac will never see Airport as Ethernet is way faster).

Put all that back and there would be no way to get in what I have in there. So, overall I think you probably have a better setup internally.

As to the bottom fan, yes it does get some dust, but not much and here's why…(pic attached). My Mac is sitting on two blocks of wood (formerly the legs of the table above it). This is giving it about six or slightly more inches of space above the floor. The last thing I want is for the fan in the bottom to be blocked by the carpet.



I essentially have two intake fans. One in the front and the stock one (with a Silenx fan) in the rear. Two exhaust fans, the stock one on the side (again replaced, this one is a Cooler Master JetFlo) and the bGears in the bottom.

I also replaced the stock PSU fan. Every fan, except the Silenx fan is higher CFM than stock. But the Silenx fan is more efficient with airflow so it makes up for that.

Took me a little over a year and a half to finally figure out all the thermals with this Mac. I now average at most about 109º F under load for my hard drives, the only temp (aside from one GPU) sensors I have. That is a damn good range because my temps are actually lower now than a lot of other Macs/PCs I use.

 

[oi!]

I have a pair of internally similar Sawtooth's (Sawteeth?) stashed away, and I stripped down a dead Sawtooth over Christmas, so I know what they're like internally, I still feel an MDD is a little more cramped.

Those pics, Epoxy resin, A and B, superglue X2, Scythe Ultra Kaze 120MM and second Fractal Design 60mm...

[oi!]

Just re-read the above, damn it so sounds negative! I am sorry eyoungren, I am interested in your mods. Please feel free to post away. My bad.



Ok, I'm now back on Noise Monster, I've found that neither the PSU fans or the 60mm Fractal Design exhaust fans were getting power, not sure why yet. Another thing for the ever growing 'To Do' list then!

Also, once warmed up, even the slightest load on the processor (like typing a short sentence on here) was enough to send Hush Puppy's CPU temp soaring, I suspect this may be connected to the ^above^.
Any ideas anyone?

 

[eyoungren]

No worries! We all have a right to our own opinions and I took no offense.

In any case, the inside of all the G4s has to be the poorest design thermally. I don't think Apple ever considered that people would load these Macs down with upgrades that often cause as much heat as they do. I mean the case fan alone! A 90º bend to deflect air flow out the back? Not efficient!

P.S. Call me Erik.

 

[oi!]

To Erik, and to all...

I have identified the power supply issue!
The 4 affected fans all run off the same molex/4way splitter, the problem is at where it plugs into the machine's own molex. Or would if I had remembered to plug it in!
I'm about to swap over onto it now.

 

[eyoungren]

Yeah, plugging it in would probably help!

 

[oi!]

I understand that opinion is divided on that.
Between those who believe that plugging in electrical item improves their functioning, and those who are wrong.
I like to sit on the fence on this issue.

Rigorous and methodical testing revealed that one of these worked better than the other.


Also what is this? A redundant cable tray? Structural corner stiffener? Worlds worst air duct?

On a side note, my 'new' used digital camera arrived today.
[doublepost=1456520786][/doublepost]It is keeping pretty cool now, 38.2C presently.
Definitely not as quiet with all the fans running.
4 way fan speed controller now ordered.
[doublepost=1456521642][/doublepost]Hung again, it's doing it a lot.
Any ideas why anybody?
Anything I should check/try?

Check the RAM, and check any extra PCI cards.

 

[oi!]

I can rule out PCI cards, none installed ATM.

So that leaves RAM, what am I checking for, and how?
(2Gb total, matching Corsair Platinum PC3200, 512Mb X4 - bought used off eBay)

 

[oi!]

With help (and some thermal grease) from a friend, I now have Hush Puppy running dual 1.33Ghz processors.
However, it is currently at 60.9C and rising steadily. about to shut it down.

View attachment 618719
[doublepost=1456608958][/doublepost]Now back on Noise Monster.
Very disappointed. Oh well.

So, now time to flash some Sata cards, and maybe a Fire GL X3 card too?



OK, my newly acquired PCI graphics card gives no image on the screen plugged into it. Any idea what I might be doing wrong?

 

[oi!]

Here are some pics from installing the Dual 1.33Ghz processors yesterday.
We didn't have any isopropyl alcohol, so we improvised...

On a side note, I was looking on eBay for a dirt cheap Fire GL X2 (yes X2, not X3), didn't find 1 cheap enough, but I did find PCI and PCIe raisers.
My thinking was that you could slot a right handed 3 into 1 90º raiser into the end slot and effectively gain 2 PCI slots (if you always left the case open or had an oversized case).

Would this work?


What kicked it off...
