Broken (Front) Fan/Speaker Panel - Bent/Broken Pins

Hello,
I try to clean out my G5 tower every few months, and recently noticed that the pins that the front panel [that house the fan and speaker] fit onto have either become bent or have broken off completely. This has resulted in the fan not working (the speaker still does).
I'm concerned because the computer seems to get quite hot, and the other fans in the unit seem to be overcompensating for its failure. Additionally, this is the fan that rests directly in front of the G5 processor, and I'm terrified that it's eventually going to suffer a severe and irreversible meltdown. Is this a quick-fix or a doomsday scenario? Any suggestions would be greatly appreciated!

Hello BDAqua,
Thank you for the warm welcome! I usually blow out the dust when I'm cleaning the tower, which is about every three months or so. The temps as reported by Temperature Monitor are as follows:
CPU A DIE TEMP = 48.4̊C (Specified Upper Limit = 65.0̊C)
DRIVE BAY = 28.5̊C
MAIN LOGIC BOARD AIR INLET = 25.1̊C
" " AMBIENT = 32.6̊C
" " BACKSIDE = 40.1̊C
MEMORY CONTROLLER HEAT SINK = 54.1̊C
PROCESSOR CARD A AMBIENT = 38.2̊C
SMART DISK = 39̊C
These temps are without any real programs running. I also don't know if the specified upper limit of 65.0̊C applies to all of the other temperatures. Does this information suggest anything to you? Thank you so much for your assistance!

  • Why does Mountain Lion triggers front fan in Mac Pro?

    Hi all, this is my first visit to this community and I hope there won't be much more .
    I bought a new SSD drive for my Mac Pro (early 2008). I had to install it from my Macbook Pro because Leopard in the Mac Pro wouldn't allow me to.
    Neither I could perform a bootable USB clean install since the Mac Pro didn't show the device in the drive selection splash screen.
    Then I put the SSD back into the Mac Pro and eureka, everything worked just fine. After about 30 seconds with the desktop in front of me, the front fan of the Mac triggered like if it was a constant reboot. However, the system worked just fine with no trouble but the annoying noise of the fan.
    It's an OS related problem because this doesn't happen in Leopard. Any idea what went wrong?

    Faulty installation.  Why could you not install the SSD in the Mac Pro running Leopard? Why are you running Leopard in the Mac Pro instead of upgrading it to Mountain Lion? Try doing it this way. Put the SSD into the Mac Pro.
    Erase and Install
    1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your SSD (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
    4. After formatting finishes quit DU and return to the installer. Install Leopard onto the SSD.
    Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s iCloud services; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later

             6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
             7. Xserve (Early 2009) - Model Identifier 3,1 or later
    To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
         Are my applications compatible?

  • Rear fan and front fan

    Hi 
    I've got a ThinkStation S30 (4352 A8G) and as I've put a power hungry graphics card in it, i would like to install a front/pci fan, but the motherboard fan connector(s) seem to be non-standard? In fact only the CPU fan connector seems to be standard. The 3 pin front fan connector seems to be standard lenght and width, but the "plastic taps" sticking up seem to not correspond with the plastic taps on the laso 3 pin standard case fan connector I've got (Noctua NF-B9). It seems as if it is possible to connect is any way simply letting the plastic taps on the motherboard connector just not locking the cable connector - my questing then is - is the voltage/signals in the three pins standard?
    I've also got a Noctua NF-B9 PWM which i intenden to swap the rear fan - they are both 4 pin - but again the plastic tips do not correspond exactly - but will it work - are the pins signals/voltages standard.
    All the Noctua cables/connectors have clear indications of what each pin is - can this be found for the motherboards connectors?

    Here are the pinouts for the fan connectors.
    Front fan:
    And here is the pinout for the S30 rear fan:
    You might have to manipulate the wires on your fans to get everything to line up.  If the tabs are causing you problems after you're sure you have the plug direction and pinouts correct, I'd just cut them off  They are really only there for alignment/keying to help avoid misplugs.

  • No sound from front centre speaker and sub

    I have an Audigy 2 with Creative Inspire 6700 speakers. I have a problem where there is no sound from either the front center speaker or the sub. If I test it with Speaker Setup in Control Panel there is no sound on those two speakers.
    Has anyone got any suggestions please?

    I have this issue aswell - but do not exspect any help, support from this forum.
    This company is crap, I hate them.. They will NEVER be getting a penny from me. The only reason I come here is b/c? I paid a lot of money for my card, and I'm hoping one day for a fix...

  • I am Using Iphone 3GS, Is it possible to change the complete front and back panels?

    I am Using I Phone 3GS model I got lot of scraches over the body of the phone. Is it possible to replace teh complete panel with new one??

    If you Google "iPhone 3gs parts" you will be able to find vendors that sell front and back panels.  So, I would say it is possible to replace the front and back panels.  I wouldn't recommend doing it yourself unless you are experienced in this type of work.

  • Sound only plays in Front left speak on Windows 7 with Xfi Extreme Music??

    I have Xfi Extreme Music (SB0640). In installed the lastes drivers for windows 7 (<a rel="nofollow" href="http://forums.creative.com/t5/forums/postpage/board-id/#]Creative Sound Blaster X-Fi series driver 2.8.003 [/url]), When I run a speaker test all 6 speakers work, however when I use media player, media center etc. Only the front left speaker works.
    Do I need to install creative Alchemy?
    Console Launchers does not load on boot
    Any asistance will be appreciated
    Thanks in advance

    NRe: Sound only plays in Front left speak on Windows 7 with Xfi Extreme Music? You will need to have the Creative Console Launcher which will let you have CMSS-3d or Creative Multichannel Surround Sound. You can find the newest version for your card here......

    Honestly though, dont bother with just that. Get Daniel K.'s X-FI support pack which is updated with the newest drivers and applications for your card. Plus, he tweaked those with fixes for installation/integration? under operating systems other than XP.
    That can be found here.......

  • Sound from front right speaker not working, playing out of le

    I have a Soundblaster X-Fi Fatalty and it'ss a little under year old with all current drivers. The front right speaker plays no sound but the front left speaker plays what is supposed to come out of the front right. I have it set on the 5. surround sound but it doesn?t work on any other settings. A week ago everything was working fine I have not installed anything new since then. I'm not sure if this is a hardware problem or something set wrong on my computer. Does anyone have a solution or know what may be causing this? Also I checked the speakers, they work fine.Message Edited by Nowise0 on 0-04-2006 03:52 PM

    I ghave this same problem with an XFi Elite pro card and a 5. speaker system. To get sound coming out all 5 correct speakers and subwoofer i have to select 7. speaker set up then 5., then 6. and finally 5. again then it works fine - I have to do the selection in THX from game consule mode to get it to work.

  • Can the front LCD Display Panel be use to send custom messages?

    Hi all
    Can the front LCD Display Panel on Rack mount servers like the P1-1000 or the MS-9218 be used to send custom messages?
    Thanks
    Carlos

    You better ask MSI that directly, as I doubt anybody in here can answer that question.

  • Front I/0 panel on Sound Blaster Audigy 2 Platinum ZS not fo

    The front I/0 panel on Sound Blaster Audigy 2 Platinum ZS not found by Creative Volume Control Application. Under recording sources, I can only choose from "What you hear", MIDI Synth, S/PDIF-In, CD Digital, Analog Mix (Line/CD/Aux/TAD/PC), Microphone and Wave. The option to record from anything on the front panel, (Aux-in 2, Line-in/Mic-in 2) have disappeared. I have tried re-installing the software from scratch, just installing Creative Update components and even formatting the hard-dri've and re-loading Windows but it still doesn't work!!?Does anybody have any helpful suggestions on this frustrating matter?

    If you're using a dynamic microphone, the Audigy 2 ZS dri've bay has a jumper which you can change for it to support dynamic microphones instead of electret microphones. However once this is done you won't be able to use electret mics until you've changed the jumper setting back.

  • GigaWorks G550W Front Right Speaker jack.

    I've had my G550W speakers for just over a month now, and for some reason the front right speaker is getting no sound even when the rest are. I've tried a few tests, checked all the software and connections. It seems to me that the problem is the actual speaker conenction jack on the Subwoofer. When I swapped my two front speakers the right speaker (which I initially thought was the issue) worked fine. The speaker cable is also in fine working order.
    I don't know why this has happened, the wires have been under no strain, nothing has happened to the subwoofer, so why would this fault occur?
    I'm pretty annoyed/worried now because it seems to be a hardware fault and I'm not too pleased.

    If it still vibrates after switching btw speakers and when the vol is down, it is probably dc leakage from the amplifier circuit in the sub. It better to let someone to service it before the dc burns your spk voice coil.

  • MacPro4,1 Front fan noise-since installing new drive

    Since installing a new drive in bay 4, my front fan (PCIe) is very noisy.
    This happens not only on start up, shut down & sleep wake up- but for no apparent reason.  It use to sound like a purring kitten- now sounds like clacking metal. Before doing the install, we blew out all the dust with canned air. Then did it again the next day.
    Tried resetting the PRAM & SMC.
    It is possible when blowing out the dust we forced the fan off it axis?
    Any thoughts?
    Thanks.

    You transferred the thermal sensor from the old hard drive to the new hard drive and reconnected it to the logic-board???
    If so, then perhaps it or one of the many other sensors or sensor cables is disconnected or damaged.
    One way of checking the sensors is to run the Apple Hardware Test.
    http://support.apple.com/kb/HT1509
    Another is using iStat Menus or the iStatPro Widget and look at the sensor readouts.

  • Front Right Speaker Very Very Quiet!!

    Hello,
    I have a Creative Inspire P5800 (5.1) Speaker System & my sound card is Creative Sound Blaster Live 24-Bit. All purchased about Septemeber this year, all has been working fine until today when the front right speaker has gone very very quiet!? All other speakers work fine, Can anyone help?
    Cheers,
    Oidest

    I am having the exact same problem and there is no reply to any post on this issue what so ever on the internet.
    I have all the other speakers working perfectly. I have tested the speakers on another 5.1 source and they all work fine.
    This is such a pathetic problem, which is definitely routed somewhere in the drivers.
    I have absolutely no idea where to go.
    I used to be able to turn off the Hardware Acceleration to zero and then all 5 speakers would magically work. However now when I do that it is only coming out of speaker (Centre front).
    Can't you fix your drivers Creative? I am sending this back to you for creating sub-standard drivers for your hardware.

  • Front Right Speaker Sometimes not Making a Sound, P5800

    Hi,
    I have the Creative Inspire P5800 Speakers. Every so often, the sound that my front right speaker makes is very faint. It happens all of a sudden, the only way to fix it is to calibrate my speakers from my Sound Card settings a couple of times before it returns to normal and then it does the same thing again later. My Sound Card is Creative Audigy 2 ZS. This has only started happening when I had to disconnect my cables from the back of my computer as I had to install a new hard drive and install Windows XP and drivers again. My cables are properly connected as I did a Speaker Channel Test and the calibrator reports no miswired cables. Does anyone know how I can fix this?
    Thanks in advance.

  • G5 front fan connection

    G5 dual 2.5
    I've been getting continuous fan noise for some time. Took the side off today to clean inside, and saw that the front fan (underneath the CD) has 2 wires coming from it. The first, with the bigger plug on it, is attached to the board behind the fan. The second is not, but there appear to be two prongs into which the plug should fit. Could anyone tell me whether that connection should be made, and , if so, how to do it, physically - it's almost impossible to reach it as the wires are so short. Thanks.

    Hey Nick,
    Found this if you're sure the sound is coming from there: http://www.welovemacs.com/0761046.html
    Then there's this, but I don't see the connector. Shows the wiring though, which I see is fed from one side to the other. http://cgi.ebay.com/Apple-G5-Powermac-Front-Intake-Fan-Assembly-1898_W0QQitemZ39 0009794937QQcmdZViewItem
