2001 G4 QuickSilver 733Mhz Restoration
« on: March 11, 2019, 02:01:29 PM »
Newbie here looking for help and advice on restoring an old G4 for audio production. I'm not that computer literate but I think I'll get through this. I'm hoping to quite this unit a bit and speed up the drive space.

Specs: G4 Power Mac, 733Mhz, QuickSilver, Gigabit, 2001

Questions

1. Is it worth replacing the PSU fan?
2. What SSD is compatible for my G4? I think it will only read up to 120GB, but that's fine for me.
3. Are they any other mods or improvements I should know about outside of the PSU and fans?
4. What is the most suitable case fan and processor fan?

That's all for starters. Any info will help. Thanks

-AlphaMac

I can't help with the power supply and fan questions, but take a look at Other World Computing for a selection of SSDs.

https://eshop.macsales.com/upgrades/

Look under "Legacy" and follow the menus for your model.

I have the same model Quicksilver, and I thought it was somewhat quieter than the MDD models, but probably still too noisy for any serious recording.  Good luck with your restoration!

Thanks Mardeec.

OWC is my first choice but now I need to know if a 250GB drive will work on my system, or at least read 120GB. I just want to make sure before I buy it. They've sold out of 120GB, yet the 250GB is around the same price. Seems like a waste of space to buy 250GB.

Q: Am I limited to 120GB for my entire system or 120GB per drive?
Q: If it's 120GB per drive are there other 120GB drives at half the price (or cheaper than OWC's 250GB) so I can install two 120GB drives?

Any feedback is welcome.

P.S. Yes it's a noisy unit for audio recording, but it's worked fine since the first day I bought it. I plan to use it in a other room with an Apogee Track2 converter.

AlphaMac,

I haven't done this with any of my G4s, but take a look at DieHard's post on using large hard drives:

http://macos9lives.com/smforum/index.php/topic,2765.msg17150.html#msg17150

Especially the section IF YOU ARE GOING TO USE A HARD DRIVE GREATER THAN 128 GB USE Mac OS 9.2.2

Fortunately, the Quicksilver 733 is one of the models with the correct specs to handle this.  As I understand it, as long as you keep the partitions under 190Gb, it's possible to use very large drives.

It will depend on your Logic Board if you can see over 128GB, there is a ton of info here on the forum

also... this is from our main site...

Quote
If you intend to use hard drives larger than 128GB under OS 9, then be aware that you will need a Mac with an IDE controller that is 48-bit LBA compliant. What the hell is that, you ask? Well, it is the ability of the Mac to see the total number of heads, cylinders, and sectors of large hard drives. We have tested the following Macs and they can see hard drives of up to 500GB within Mac OS 9.2.2: Power Mac G4 QuickSilver 733, 800, Dual 800, 867, 933, and Dual 1 GHz with logic board 820-1342-B (QS logic board 820-1276-A will NOT work and peak out at 128 GB)

Thanks I'll look into this. How can I tell what model logic board I have? It's not powered up right now and I'm waiting for a new PSU.

I was playing around with the CPU fan today. I had it out of the board running on a 12V adapter. I was moving the fan (with the rubber case) in its position and noticed that when pressed into position the vibration of the steel case alone increases some noise. It there's a way to isolate or suspend the fan that alone would reduce some noise.

I've been looking at this brand for fans: NB-Multiframe M8-S3 80mm x 25mm Ultra Silent Fan - 2200 RPM - 19 dBA http://www.frozencpu.com/products/8399/fan-515/Noiseblocker_NB-Multiframe_M8-S3_80mm_x_25mm_Ultra_Silent_Fan_-_2200_RPM_-_19_dBA.html?tl=g33c165s356#blank

The specs are a little lower than the original fans but I plan to compensate some airflow with something. I'm not worried about cosmetics. I'll drill some holes if I have to.

Would this work for the the case fan? I know opinions will vary but I'm betting the soft material will be less noisy from the original without sacrificing CFM flow.

The part Number described is literally stamped on the top of board, no need to remove or power up, just look (google location if you cannot find it)

As far as fan mods, search the forum, we have covered much of this many times... changing fans from 3 wire to 2 wire configurations, usually result in them running non-variable (full speed only)

Got it. Thanks. I posted an image for layman's like me.



I'm drilling larger holes right now on the steel grill frame for the fan case. I seen the post on making an outter grill on the plastic case. I might try that. It makes sense to get more hot air out of the unit.

Here's the steel case grill drilled out with larger holes. The drill bit size as 9/32. I used a vacuum pressing up against the grill from the inside to catch the shavings while drilling from the opposite side. This kept the grill from bending while I was pushing against it with the drill.

One thing I noticed while half way complete was the noise of the vacuum when pressed against the larger holes compared to the old sized holes. The old holes would screech at a high pitch while the larger holes were drastically less noisy. Obviously there's less obstruction for air to flow now.

I might attempt the plastic casing now. Not sure yet.

i dont think you would need to add any vent holes to the plastic case. there's an air-gap in the bottom where it meets the metal frame which allows it to vent, probably more than sufficient for your needs. plus, why ugly up the case?

also have you considered widening the inlet holes toward the front of the case? Especially if you're increasing the air output, there's a potential that there may not be enough ventilation to pull in cool air in which case the effort of the new exhaust is wasted.

you might, if you're feeling daring, want to replace the fan in the PSU. ive found those are usually the worst culprits. but, if you're buying a new PSU, it may not be an issue.

So for your unit, use hard drives that are 120GB and smaller, it will NOT see large drives

@refinery I'm just doing some minor enchantments until I understand the airflow dynamics of this unit. I'll check out the inlet holes you're talking about.


@DieHard Thanks. I figured. But does that mean 120GB per drive or throughout my entire chain? I couldn't find anything specifying that. I'd still be happy with a fast 120GB SSD drive since I transfer everything to my main computer anyways. But if I can get two 120GB going that would be great.


I got my PSU today. What's the best way to test the PSU out of the box? I seen the paperclip test but I don't want to try it until I know for sure.

128GB Max PER DRIVE... So, you can do (2) on the main Controller and an additional drive under the CD ROM (instead of a Zip); (3) Hard drives @ 120GB Each :)

@DieHard That's good enough for me. Now I have to get this thing actually running.

I did some basic tests with a multimeter on the new PSU and I can't get a voltage reading across the pins. The seller said it was tested and power cable is fine. Could it be the fuse?

I might need a backup plan here cause I need to get this unit running asap. Can anyone recommend someone who can rebuild a G4 to spec? Or has a refurbished one for sale.

Ok I've made numerous attempts to get a voltage reading across the PSU pins and no luck. I tried to jump the pins as a last attempt and no luck either. Before I conclude this is a dead unit is there anything I should try? I haven't installed it yet. Would it matter? Does anything on the logic board affect or turn something on to get the power going? Any advice is welcome.

How reliable is the source of the PSU? Can you return it easily?

If you take your time and carefully install it and still
it does not work… then return it. If the PSU is dead,
it won’t hurt your QS and you may then know for certain
that the PSU is completely deceased. AND make certain
that your onboard battery is good / fresh (& if not, removed.)

*Even though some have reported no-boot status without the battery.

Once you install the PSU, take note of exactly what the machine does,
even if it does not completely boot with the new (used) PSU.
Or, even if it does absolutely nothing.

For that matter, might as well test the PSU already in the machine in the same way that the new PSU has been tested, to see if it shows “no voltage” as well… to “test the testing”, so to speak.

Evidently the original PSU was working… in order to power the fans and provide the noise that AlphaMac seeks to quiet.

Did the original PSU die, or is it slated to be replaced because of its’ fan noise? If it’s a matter of a bad fan in the original PSU, then maybe move the fan from the new PSU to the old one.

AND, if the Quicksilver is to be sequestered in another room as mentioned… what’s a little fan noise?

Unless it’s freakin’ screaming through the walls. ;)

@FdB My old PSU was dead. The other day I removed the fan and powered it with an adapter and it was hardly moving on its own. I had to push it with my finger. The short story is I came home one day and seen my mac off -- power it on and it shut off again 20-30min later. Tried again and that was it. My worry is if the logic board was damaged.

---

I tried the installation a few times. Nothing happened. Dead cold. So I opened the PSU as far as removing the circuit board a little bit -- don't worry I planned to short the capacitors with a neon bulb but when I measured them there was no voltage, even after plugging the unit in 20 minutes before. I don't think they're filling up. 

I also looked around for any burns parts. Nothing. Other than a small area on the circuit board with some slight discoloration everything looked ok, but what do I know. The odd thing was there was no dust at all when I blew it out. Maybe someone opened this unit already.

Anyways I was prepared for this. For any newbies reading this make sure you find a reputable seller or someone experienced in refurbishing PSUs. These units are getting old so the chances of something going wrong increases over time.

Time to move forward with the next plan.

Does anyone know of this person's service for refurbishing PSUs? They have a pretty high rating.

Question: If I get the PSU fixed but the logic board is damaged, am I running the risk of burning the PSU? I might even get both PSUs fixed to keep one for the future.

Ah, you posted just as I was about to. Looks like Andy has raised his prices a bit….

Appreciate the explanation. Still wonder about you trying to solve fan noise in a machine that wouldn’t run… unless your PSU has just died very recently. But, no matter.

For PSU rebuild / refurbs contact Andy Cuffe (acuffe@gmail.com) down in Austin Texas USA. He’s a very good guy and may even rebuild Quicksilver PSUs for slightly less than the MDDs. He did say back in November of 2017 …that he could offer members of this Forum a price reduction for his services.

And here’s an eBay link (provided by GaryN) for Andy’s services:
https://www.ebay.com/itm/REPAIR-SERVICE-Apple-PowerMac-G4-Mirror-Drive-Doors-Power-Supply-MDD/141030901102?hash=item20d618c56e:g:~RsAAMXQysxSAA61

If you’re now stuck with (2) bad PSUs, Andy might offer you a little for one of the dead ones. Ask him. And be certain to tell him that you're a member of MacOS9Lives Forum.

All of this, if you can’t find a good source for this service… up there in Canada.

Only other simple thing I might suggest at this point is to check continuity through the PSU’s fuse. But if the machine did start & run, only to then die later (never to boot again) then it’s most likely RIP… PSU.

I’ve two QS “spares” at present. One completely dead and the other one with a dead fan power circuit… or I’d simply send you one. My regrets. Do contact Andy.

And no, it shouldn’t damage the PSU if the logic board is toast.

I had this unit in a rackmount covered with sound panels -- it was a hotbox, but it ran for more than a decade like this. Ha. So I never paid that much attention to the noise. Eventually it gave out. So that's when I decided to give it some love.

I'd rather fix this unit and use the old version of Pro Tools than commit to new software and hardware. The way things are going now everything requires an annual licensing fee. It's ridiculous and expensive. And than you have to deal with all the bugs and updates. The old Pro Tools ran flawlessly with no latency. For me it's worth to fix.

Thanks for the info. I'll contact him and see what he can arrange. I'm hoping he can switch out the fan with a newer fan too.

Hair Dryer trick works on many bad QS Power supplies (search for it here or google it),

basically, leave the unit plugged in, heat the PS with a hair dryer for about 3 to 5 minutes via the back and obviously don't hold it is one spot too long on "super hot" mode; then try to power on, if you don't unplug the PS from the wall, it will then start on it's own; clients sometimes get 1 to 2 years out of a bad PS in this manner

Dryer didn't work. I'm done with short term solutions. This PSU needs to be refurbished anyways.

I might get lucky and scoop a 800Mhz QS with Tiger installed. Then keep working on this G4 as a backup. Now I have to check if I can get a copy of Pro Tools for a mix/24 system and run it on Tiger, unless I'm able to wipe out Tiger and install OS9.

I'll be purchasing a new G4 soon as a quick resolution to get production up and running. If I'm lucky I'll be able to swap out my old drive into a new G4 to retrieve some session files. I'm guessing this would only work with other G4 QS models, or can it work with higher models, say G5? I don't know.

I still plan to rebuild my current QS and experiment a bit, so I'll keep this thread going with updates.

After playing with the fans, in and outside the box with a power adapter, I'm convinced the internal steel case is pretty much an echo chamber that needs dampening. Just take a pen and hit the inside steel case of you'll hear it resonate at a high pitch. With the fans and wind blowing (moving air creates noise), all that noise is circulating inside the unit and mostly coming out the back. I'll keep you posted on some ideas I plan to try.

Here she is. It's a B board. It was from a local seller. I drove as fast as I could when he told me it was a B board.

I just need to confirm if I can swap out this drive for my old drive. I read some posts online and it says this was only possible with OS9 as OSX and later versions need need to recognize hardware. Any thoughts?

I had my old G4 in a rackmount with sound panels around it — then it stopped working — so I never had the chance to study the noise. Now I can hear it running on the bench.

I didn't tear it down, but just to confirm that the fans on this unit weren't modified: my case fan and PSU fan are both blowing air out. I tested with a small piece of paper. Is that right?

Yes, fans do seem to blow weird... but if you've not changed anything, they're blowing correctly.

AND, just swap out the drives and try to boot it from your old drive. Should work. If not, it won't hurt anything. Just won't boot.

Only one HD in your old 733 QS? I ask only if the old HD was setup as a slave or a master. If there was only one drive, then chances are that is already setup correctly as a master.

Man that worked like a charm. I switched the drives and it fired right up with no problems.

Now I have to figure out what internal drives to install and whether to go PCI or IDE.

tough call on that machine. the internal bus is only ATA5 (66MB) sec so you could get an IDE-SATA converter, or try to track down a OS9-compatible PCI SATA card on ebay. they pop up from time to time. I have PCI SATA cards in two of my OS9 machines and its very nice and fast.

@refinery: I've been reading this post regarding PCIs on G4s http://macos9lives.com/smforum/index.php/topic,803.msg2903.html#msg2903

Does this mean no matter what I'm limited to 66mb/s whether IDE or PCI, or have other configurations exceeded this limit? I don't even know what my current 7200 HDs are transferring at. What's the best way to test it?

Re: 2001 G4 QuickSilver 733Mhz Restoration

I selected a bunch of case fans measuring around 90-110 CFM and then narrowed it down to SilenX and Noiseblocker. I might modify the 140mm to fit my 733mhz and use the SlienX on the 800mhz, although at 38mm wide it might be too tight to fit the case.

The dBA/CFM ratio implies the lowest noise per volume of air moved. In other words the lower the better. I'm a bit skeptical about the SlienX being so low — almost 50% below average. Maybe it is that good.

@refinery: I've been reading this post regarding PCIs on G4s http://macos9lives.com/smforum/index.php/topic,803.msg2903.html#msg2903

Does this mean no matter what I'm limited to 66mb/s whether IDE or PCI, or have other configurations exceeded this limit? I don't even know what my current 7200 HDs are transferring at. What's the best way to test it?

you're only limited to 66mb if you stick with the internal bus. If you go with PCI based solutions, its dependent entirely on the card, you could get an ATA-100, ATA-133, or a SATA-based (150) card.

The drives however are really the limiting factor. A typical 120GB spinner drive will probably not come close to saturating that connection. ATTO Disk Benchmark tools here:
https://www.atto.com/downloads/42#9

do include a benchmark tool, but to be honest I dont know if its limited to ATTO only cards. worth a shot I suppose. That would tell you if your existing drive is saturating that link or not.

Have you looked at Noctua fans? They are expensive but some of the best you can get for noise levels. I use them almost exclusively and they never disappoint (and they usually have 7 year warranties too... on a FAN!)

@refinery: Thanks. I might go with SATA. I'm trying to find an internal/external PCI card to setup a swappable external drive for transferring files to my main computer. 

Noctua's dBA/CFM ratio is very low with SilenX and Noiseblocker, but for my use the CFM isn't high enough. I have PT pci/DSP cards that add  extra heat to my unit. If I was going for noise reduction in a stock G4 I'd consider this fan. I've updated the specs with Noctua.

well there's plenty of other models besides the ULN that are super quiet. I use the (now-discontinued) P12 @ 1300RPM in my MDD and also my Hackintosh and they are unbelievably quiet. They also give you in-line resistor packs to slow down the speeds if they are too loud for your taste.

i only keep pushing the noctuas because they have a very good reputation (not counting my own personal excellent experiences with their products) but I know other manufacturers have been accused in the past of woefully overstating their fans' performance. might be worth doing some googling to see how accurate those others are in their claimed cooling statistics. I know nothing about NoiseBlocker but I do recall hearing SilenX being accused of that in the past.

ive honestly been surprised Apple hasnt made moves to buy Noctua, their cooling tech is so well-made. It seems like the perfect match to Apple products.

regarding the PCI sata card, the only one I know of with both internal and external ports is the Seritek 1eVE2+2, but good luck finding one of those as they are long discontinued. However, you may have luck finding one with a compatible chipset that can be flashed. Check out the storage forums for more threads on those. Alternatively, if you found one with internal ports and arent too picky about frankensteining your machine, you could always use an internal sata to e-sata adapter cable.

@refinery: Quiet out-of-the-box is one thing, how long it sustains at the same dBA level is another. The chart below compares the noise increase of Sunon's MagLev tech to general fans. Any new fan will sound great out of the box because it's balanced with minimal bearing friction. But after 10,000 hours it might be 50% than the original dBA rating due to mechanical erosion.

For someone like me that wants durability as opposed to the lowest noise reduction, what they want is sustainable anti-vibration.

well for what its worth, the noctuas in my hackintosh are at least 4 years old at this point and ive never noticed any noise increase in that time. whichever you end up choosing im sure it will be a great improvement over whats in there now.
