Quicksilver G4 - noise in tower

My tower is starting to make a clicking or squeaky fan type of noise after being on for a while. I tried cleaning the dust out, but it still is making that noise. Could this be my hard drive starting to die? Do you think it's serious enough to warrant taking it in to be serviced?
Thank you.

What model tower? I know my computer has at least 3 fans (CPU, case, and power supply), and some have more (e.g., video card). Try opening up the box while the computer is running and isolate the source of the noise (if somebody has a car stethoscope you can borrow that might help). If you're not having drive problems then it most likely is a fan. Bearings can get old and wear down, or fan blades can get dirty and unbalanced. In some cases they can be restored with lubrication. It would help to know the specific noise source first before providing details.
If it is the drive then make a backup of all your files ASAP because a mechanical failure in a drive is usually fatal to the drive.

  • Reliable SCSI card for G4 tower (Quicksilver or other G4 tower) with OS 9 ?

    Good morning.
    I am trying to setup a G4 Quicksilver (or another slower G4 tower) under OS 9 to be able to use a very nice Epson wide format scanner (no OS X drivers available). It has only a SCSI Centronics 50 pin connector.
    1. Is there a reliable and available (with OS 9 drivers) SCSI PCI card that will work in a variety of G4 towers under OS 9?
    2. If the card doesn't have the 50 pin Centronics connector, how do I adapt the scanner to the card input?
    Thanks for your time.

    When SCSI was built in to Macs, it was what we now call "narrow" SCSI. Apple used the DB-25, a 25-pin connector that looked like an RS-232 connector (because it was the same connector). To use it with typical 50-pin Centronics devices, a cable called a Macintosh System Cable was used. The Macintosh System cable swapped the signals around and connected the few grounds in the 25-pin connector to the many grounds in the 50-pin connector. Almost all devices came with two Centronics-50 connectors. Connecting multiple devices together was accomplished with a Centronics-50-to-Centronics-50 cable, and the last connector on the last device was filed with a Terminator.
    Most of the add-on cards available later were "fast", "wide", "fast and wide" SCSI, optimized and tuned up to run faster than the built-in's maximum 5 Mega Bytes/sec. They used more complex cables and had more rules for proper operation. Your scanner alone cannot generate data fast enough to fill up the original "narrow" SCSI. So you need none of the later stuff.
    Faced with no SCSI port on the new Blue & White G3 (the first Mac without a SCSI port since the original Macs), many users at that time installed the Adaptec 2930 card in a PCI slot to run their scanners or occasional other SCSI devices. The card is capable of Fast-20 speeds if your device supports it, and works with G3s and G4s with PCI slots. The card has an external 50-pin connector called HP-DB50, which has nothing to do with Hewlett Packard, it means Half-Pitch (the pins are twice as close together as on the DB-25 connector). HP-DB50-to-Centronics-50 cables are readily available. Support for the Adaptec 2930 is still available built into Mac OS X.
    If you go with the Adaptec 2930 card, it will run your scanner, not require any adapters -- just one cable converts to the connector you need, and if you can get an "active" 50-pin Centronics terminator with an LED, your life should be easy.
    There are tons more solutions available. Each comes with a little more added complexity and more potential features if you want to do additional things with it.

  • Put superdrive from g4 quicksilver into a g5 tower?

    Hey all,
    I bought a g5 tower when my g4 quicksilver's power supply (or something) went south. Trouble is, the g5 only has a combo drive while the g4 had the super drive.
    Will the super drive from the g4 fit into the g5?
    Thanks
    Ted

    Sure, here's the G5 part...

  • Quicksilver g4 noise reduction

    I recently purchased a used QS G4 ($37) to go use os9 for some of the old apps, for fun . After turning the thing on I realzed that the psu fan runs really really loud!!!! so I researched and found that removing the finger guards reduce this noise significantly, before i went ahead I was wondering if there are any instructionals that show how the back plastic bezel (plastic that goes over psu and the pci fan with holes in the back) comes off. Also, if there is anything that you've done to reduce the noise on your g4 I would love to hear about it. Please let me know.

    Blow the dust out of the PSU. That can help a lot.
    Every QS that I have ever bought (used) benefitted......
    Replacing the  PSU fan with one like this also helps bunches:
    http://www.vantecusa.com/en/product/view_detail/119
    I also like the Thermoflow Vantecs for the CPU fan. That little bugger can be noisy....
    Other fans that I have used in the PSU are made by Verax, sold by Zaward.
    Either the 3500 or 4000 RPM  80 mm fan work well, both being quieter than the OEM PSU fan.
    Be sure to wire to the original wires to get voltage regulation.

  • Quicksilver Power Mac Spinning Wheel Issue

    I have a Quicksilver P-Mac 867mhz tower that has 10.4.11 installed. 3 days ago it was running super slow and I had to relaunch the finder. It froze and when I rebooted the Mac it comes up to the Apple logo screen with the spinning wheel and that is it. Nothing else comes up even after sitting there for 20+ minutes. From the other posts, I thought maybe the batter was the issue, but I installed a new one today and that didn't fix it. I have reset the PRAM and have tried booting up in safe mode. No luck with either item. Could it be the power supply? This Mac has 2 internal harddrives, the original 60 gig and another 120 gig. I have had the system for 5+ years with no problems.
    Any thoughts on this issue? I would think the hard drives should be good since I do not see the flashing ? icon come up during the boot process, but I also cannot insert a Tech Tool CD to reboot and try to repair either.
    John

    When I try to boot up the Mac, it gives the Apple logo and then the spinning wheel kicks in and just sits there. I can let it do this for 10+ minutes and nothing changes on the screen. So, my problem is that I cannot insert TTP CD into the optical drive because it will not open from the keyboard command.
    This seems to be a big problem not being able to open the optical drive so that the Mac would boot off of TTP to try and fix the problem. Any other thoughts?
    Thanks,
    John

  • ADC from vid card to a VGA 2nd display, out of stock?

    We have an old quicksilver G4 800 mhz tower that a co-worker wants to have a 2nd display attached to. The card has 2 outputs, a VGA and an ADC. About a year ago, I went to our local Apple Reseller (not an apple store) and bought a ADC to VGA adaptor for 30 bucks (for another machine in use). It was by Dr. Bott. There is nothing on their website now. Dr. Bott service stated that Apple had something to do with the discontinued status? Locked down their technology?
    Some site show any ADC to VGA adaptor discontinued.
    What is up?
    Alternatives? Should I just get a new cheap graphics card? or are there ther alternatives. Yes, this is old technology, and we will get new computers, but we will have this machine a few more years...
    Thanks for any help
    Mac Pro 2.66 Ghz   Mac OS X (10.4.7)  

    Apple did not try to stop others from using ADC. They made it an open standard, but few other manufacturers used it. Formac did make a LCD display with ADC. Most display makers didn't want to make models that would only work with a Mac, even though it would be cheaper (no power supply needed). Other computer makers didn't use it because they would need bigger power supplies (Apple made a CRT with ADC that needed 113 watts), adapters would be needed for most displays, and they would need special graphics cards. Because of lack of demand from other computer makers, no graphics card maker made any ADC cards for non-Apple computers.
    Apple dropped AC for several reasons:
    Multiple displays were being used more, and there was only one ADC per computer. DVI to ADC adapters are expensive and messy.
    They wanted to sell their displays to non-Mac users.
    Bigger displays needed more power (30" needs 150 watts)
    With their main customer gone, the connector maker dropped the connectors, so adapter makers have no more parts for the adapters. Adapters are now scarce and expensive, but it's not Apple's fault.
    There are still a few ADC to VGA adapters for sale:
    <http://www.mac-pro.com/s.nl/it.A/id.230/.f?sc=2&category=128>
    <http://www.welovemacs.com/mcaadcvga.html>
    If the Quicksilver is the earlier (2001) model, such as the dual 800 Mhz, the adapter won't be useful with any of the graphic cards that originally came with it. It will work with 2002 Quicksilvers, such as the single 800MHz.

  • Question about Sound Isolation/Reduction and Heat

    Hi all,
    My AGP Sawtooth G4 tower is loud
    -OWC 1.4 Ghz upgrade w/ fan
    -8500 vid card w/ fan
    -OEM fan
    -Seagate Barracuda 160 GB (loud!) + two other HDs.
    i haven't measured the decibel level, but it is significant.
    I do some home-audio-recording, and I want to know if I build/use an enclosure to seal in the noise, will excessive heat be a problem.
    thanks in advance
    Sawtooth g4   Mac OS X (10.4.6)   1.4Ghz upgrade, 896 ram

    re: the amount of noise reduction...any would be great. Didnt know it (or think about it) when i bought it, but the upgrade Seagate Barracuda HD is apparently notorious for being pretty loud. then throw in the 1.4 Ghz OWC processor upgrade (has a fan instead of a heatsink on the chip). those two + the stock fan crank some noise.
    the tower is in a computer desk now (cheap officemax type command center) - in the 'computer spot' behind a door. i'm tempted to just seal the box and put up soundproofing foam inside...but heat becomes a concern. i'll look into a fan, that seems like the logical(smart?) thing to do.

  • Noise levels on Quicksilver G4 versus Dual 1.0 MDD.

    I have the Quicksilver, it's noisy, but I can tolerate it. I am looking to buy an old dual 1.0+ G4 tower to run some older versions of Logic just for fun. I see a few Dual 1.0, Dual 1.2 or what have you G4s on ebay and craigslist. I recall the MDD models that these must represent were the noisiest beasts of all time. Were they really that much noisier than my old Quicksilver? Does anyone have first hand experience with these models?

    That's what I was afraid of. The MDD dual G4s are about the best bargain for older macs right now. But I don't think I could live with anything louder than the older G4s. I'm in a small room by myself, and having that extra noise would drive me nuts. Guess I better save up for a mac mini!
    thanks.

  • G4 (Quicksilver) Tower Speaker

    Even though I've had my G4 for a while now, I was just curious as to why the speaker in the tower has never worked with the (included in purchase) external speakers connected? I remember my old Performa's tower speaker used to work with external speakers connected...which kind of gave me a 3-way computer speaker system at the time. The tower speaker also gave me more bass with music and movies. Does anyone have a clue as to why the tower speaker in the G4 will not work with my current configuration? Thanks for listening....

    Hi, Labrynth51!
    Welcome to the Discussions!
    Your Mac was designed this way. OS X will output to one or the other, but not both at the same time. There's nothing wrong with the Mac, if perhaps you are concerned that maybe there is. If you look at your Sound Pane of System Preferences, you'll see that you can select one output or the other, but not both.
    Hope this clears things up a bit.

  • I did it....Old Quicksilver Tower 800 Meg.  with new CPU

    I have a old Quicksilver tower which was 800 Megahertz...I put in the OWC chip in it some months ago which upgraded it to 2 gigahertz...I have a 40gig HD. That is the biggest problem. With this software you need at least 80 gigs. However, I had to ease the drive and reformat it, but it works. I don't have a dvd drive in this old rig so I used a Macbook laptop and firewire connected it-laptop was the target drive and it installed. I could have taken a long nap....but I was to anxious to see if it would fail...It is really nice!

    I didn't even know they made 2 GHz G4s. It's cool you got it working though

  • Quicksilver G4 roaring noise

    My 2002 QS G4 has always made a noticeable humming noise which I could tolerate, but in the last few days, that hum has turned into a wobbling roar that can no longer be ignored. I have not made any recent internal installations, and inspecting in and outside the case didn't reveal anything unusual. All the internal drives and cards seem secure and stable, and all cords and cables appear to be tucked away.
    Is it a broken fan? I counted at least three of them inside the unit.
    Is there anything else I can do to muffle this noise? It's now affecting my ability to concentrate. Any helpful suggestions are appreciated.

    Standard household Vacuum Cleaners with plastic hoses have a reputation for generating huge static discharges. You may want to find one with metal tubes, or a commercial unit specifically for computer use, or use compressed air.
    If you use compressed air, do not use it in the house or the dust will go everywhere, and your name will be mud. Take it outside to clean with compressed air.

  • Are Quicksilver G4's as loud (fan noise) as MDD G4's

    I'm considering a new (used) Mac G4. I love my MDD Dual 1GHz (operationally) except it is as loud as a "Mo-Fo". I cant really enjoy listening to iTunes while using it. Does anyone know if Quicksilver G4's are a somewhat quieter machine? That's it... thanks!

    The MDDS were also called the "Wind tunnels", a QS should be conderably quieter.

  • Noise, noise, and everywhere at that!

    Greetings-
    Alas, but I have yet another pot to stir regarding noise. Not that it is intentional, but every time that "noise" word gets tossed around somebody is probably gonna get a little fired up.
    My Quicksilver G4 tower loaded with hard drives is my "baseline" for computer noise. Now that critter is loud.
    There has been much discussion on the Apple Discussion boards about the "noise levels" of every G5 iMac model released. I personally use 2. If you start one of these up in Target Disk Mode, all fans run at maximum and continuously, and in my opinion, that would probably be the maximum possible noise that system could put out. Normal iMac operation, even when you push them, does not achieve that maximum level. As to be expected, they do get much louder when working on system-intensive work.
    In considering the purchase of a G5 tower, I have been reading much about the relative noise levels of the beasts when in various modes of system-intensive operation. I've got to think that nothing can beat my G4 tower in terms of noise levels, but one can never be sure.
    I am looking for some feedback regarding the relative noise of any of the latest G5 tower offerings. I would prefer if it could be presented as in relationship to either other models of Macintosh computers that you are familiar with, but if you could even compare the noise level relative to all of the gadgetry (fax, laser printer, guy in the next cubicle) contained within a typical home or small office, that would be great too.
    And has anybody fired up a Quad in Target Disk Mode and observed that noise level? I've got to believe that sound has got to be a tad annoying.
    Peace and thanks-

    PowerMac's G5's are pretty quiet generally, sure if the OS doesn't load or kernel panic's the fans default into turbo mode, that's a safety thing and you really want this to happen actually.
    It's the OS that settles the fans down, not the hardware.
    The Quad is your best choice for power and price, for $800 more than a dual 2.3 you get twice the power and 3x the longivity.
    The Quad also has a new power supply which the slightly annoying "beeping" sounds of previous PowerMac G5 models has been silenced.
    The Superdrive will kick up when a cd/dvd is inserted, that's the loudest sound I've tested and one doesn't do it often.
    Sometimes a video card/PCI card will tax the PCI fan slot a little and if you have the machine facing you you may hear this fan kick up because it's right up front. A cool room ~75ºF will keep a PowerMac near silent at full CPU load has been my experience.
    All the PowerMac G5's are CONSIDERABLY quieter than some previous Mac models. Like my old 800 Mhz eMac, it produces a constant 70db vacuum cleaning sound thats most annoying.
    My PowerMac G5 usually stays below 60 db in a 75ºF air conditioned room, unless I pop in a cd then it goes up to about 75 db for a time.

  • Did the noise levels decrease with the G5 versus G4?

    I have a dual 1.0 G4 Quicksilver tower. It is noisy just sitting there doing nothing.
    I have a chance to get a dual 2.3ghz G5 tower for $250. Nice upgrade for not much dough. It's local and so no shipping.
    But, I'm worried the added power will bring equal or worse ambient noise.
    Anyone have any thoughts on this?

    I was trying to use a single 733mhz G4 tower for Logic and surfing. It was just too little, could hardly do anything, but I really didn't want to spend $600-700 on a mini, so for fun, I found the dual 1.0ghz tower for $200 last year sometime. When loaded with Leopard and the max 1.5 ram, the thing actually runs nicely. I was using it for basic stuff. It's snappy, feels very similar to my MBP for most things. But I got a new drum program and it ***** up most of one cpu when running. I can freeze the track and get back all of the cpu, and I needed to burn a DL dvd, and realized I only had a regular R/RW in the G4, then I wish I had FW800 for my drives, and next thing I know, I'm on Craigslist looking at G5s. Found one nearby for around $100 less than currently on ebay and just jumped. Figure if it's too loud or slow, at least I won't lose money.
    I did have the dual 2.66 MacPro when it came out. That was a nice mac, I really loved it. I just didn't need both a $3K desktop and $3K laptop, so I thought the laptop would be more useful in the long run. It has, I'm starting the 4th year with the MBP and it still keeps up just fine.
    And honestly? I still have a soft spot for pre-intel macs. I've been using them since 1989 daily, and it's kind of cool to still use a powerpc in my eye. Silly, I know.

  • Can I install a 100mb Zip drive in PowerPc G4 Quicksilver?

    I am using a PPC G4 Quicksilver to replace a PPC G3 desktoop. I have a collection of 100MB zips I would like to access. Can I install an internal Zip 100MB drive in the second drive draw in the tower? If yes, ATA or SCSI.
    Thank you,
    Ed Gaiano

    Even if you don't get a bezel it might be a good idea to close the opening. I don't know how closely engineered those computers are to air flow and cooling and leaving off a bezel might change those characteristics. I did something similar on a different model computer once and used foam rubber to pack around the edge. Not pretty I'll admit.
