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
Here is a good place for additional info on things.

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.

Front panel connections

.I am building a new system but the front panel connections in thr mobo manual need clarification for me .
Front panel connections jfp1 & jfp2
jfp2 -- 4pin speaker wire 2-8
3pin power led 1-5
jfp1-- 2pin hdd led 1-3
2pin reset sw 5-7
2pin power sw 6-8
In the manual it has a 2pin power led 2-4 but there is no wire do I take it that you do not need this .
USB 2 & USB 3
4 pin connector vcc , usb- , usb+, gnd 2-8 or 1-7
this cable has an extra gnd wire I would imagine you just leave this unconnected as there is no 9pin & 10 is usboc .
Front audio
pins 5-6 & 9-10 not to be used .
So that leaves me with 5 connections but manual does not say where they connect .
ear left
ear right
mic vcc
mic in
grd
Hope I have explaine myself ok but woulsd rather be suree before I go any further , I have the rest of the pc in place .
Regards Ian

Found these on an other site much more explicit than manual . There was connection diagram on manual but no direction as to + or - so would imagine 1for example is hd led p for positive .
PIN SIGNAL DESCRIPTION

Front firewire connections

My 845PE Max2 MB gives me 3 IEEE 1394 connections on the board. I am using two of the three available connections for the S-Bracket on the rear (J1394_1 & J1394_2 and they operate OK) and trying to get J1394_3 connected to the front panel. I have an Antec case with six wires to front panel. Here is how I have them connected to J1394_3:
Pin 1 - TPA +
pin 2 - TPA -
Pin 3 - Ground (VG is Antec ID)
Pin 4 - open
Pin 5 - TPB +
Pin 6 - TPB -
Pin 7 - Power (VP is antec ID)
Pin 8 - open
Pin 9 - key
Pin 10 - open
It's not working! Ok, what am I doing wrong. Can anybody help?

My buddy had that same problem with his Antec Sonata case, it seems that the front Firewire connection was wired wrong on the case, from the factory. He had to take the wires out of the connector, and rewire it to work. Two of the connections were backwards, like the person was looking in a mirror when he did it Check them out really good.

A1330n front panel connections - mic, headphones, speaker

I have a hp1330n desktop computer
I am updating the motherboard to an ASUS p8H61-M LX plus
The front panel connections for start, reset, hd activity, etc. all work fine when plugged into the 10-1 connector on the asus motherboard
I am trying to figure out if / how I can connect the front panel 4 pin connector for the mic, headphone, speaker that use to be plugged into the 1AUX_IN1 connector on the old motherboard that shipped originally with the a1330n.
There is a 4 pin speaker out connection available on the asus motherboard - +5V, GND, GND, Speaker out, but not sure if I can connect the 4 pin wire coming from the front panel - white, blue, green, red wires (with some modifications) into these available 4 pins.
Or do I just forego this functionality after the upgrade and leave the plug dangling in the case?

I found this, I guess it is compatible with the azalia connections: http://forum.thermaltake.com/files/audioconnector_307.jpg
But I have one more question... looking at the end of the card, which pin is pin ? top left?

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

       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

K450 motherboard front panel connection

Hi
I need to know the layout for the front panel connection on CIB85M. Searched all around and the closest i got was this, but i dont understand the language:
Link to image
Moderator note: large image(s) converted to link(s): About Posting Pictures In The Forums

Please, I too am looking for this information: pinout diagrams and or wire coloring/descriptions for the Front Panel, Front USB3.0 and Front Audio headers which all appear to be non-standard. Also, there was a Sensor Header that it would be nice to know the layout for just in case I can find a place on the new mobo for it. Our CIB85M is fried so trying to connect everything to a new MSI mobo. Any assistance would be appreciated. Thanks!

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.

E31 - Front FAN at full speed after bios update !!

Hello,
we have a Thinkstation E31 (2555-22G), and today after the Bios update with the Lenovo system update tool the front Fan (near the SATA connectors) is at full speed constantly. it is just impossible to stay in front of this computer because of the noise, i had to disconnect the fan.
I tried to flash to an older version available on the site but it doesn't change anything.
I tried to reset the BIOS to default, and also removed the battery from the motherboard.
I found in a faq but for another model to remove the power cable and press the start button during 10 seconds.
I didn't find something working, there is no fan control setting in the bios, or it is well hidden...
What can i do ??
Thanks for your help.

The beeps you're hearing are part of the CMOS clear process, so they are normal. Once you hear the beeps, you should be OK to shut it down again.
I'm not necessarily convinced a bad fan is the cause of the issue if you truly only experienced the higher fan speed after a BIOS update. But I also don't want to work on the same issue from two angles/paths at the same time....so I'm going to say let's wait and see what happens with the service route first and go from there.
If you happen to try it again or see the message again...I'm curious what error codes you're seeing after the system starts and you get the two POST beeps. A message about corrupted settings sounds like it could be important A picture might be helpful here if you can capture one.

Nasty rumbling noise from front fan.

Hi Guys,
My nice new Mac Pro that was near silent yesterday has now has become very noisy today, sob, sob.
I have removed the disks and started it up with the cover off and had a listen and have tracked the loud rumbling noise down to the front fan. After turning the machine off I stuck my fingers in and there seems to be some play in the fan blades.
Has anyone else had this, and if so does it go away or get worse?
Thanks for any help
Andy

Fan bearings wear out and become louder over the years, but it sounds like you got a bad ball or sleeve bearing from the factory, it happens...
I don't know how easy it is to replace the fan, but to avoid messing up your warranty you should get an apple service center to look at it.
You could try waiting it out for a week or two though. If you're lucky it'll become less noisy after grinding away on the bearing for a while.

Loud front fan on 2006 model - almost figured it out need more help

I've been having problems with a noisy whirring from the front fan. Figuring I'd check it out, I opened up the computer, tried to dissamble it, failed, took out what dust balls I could and put it back together.
When I restarted, the computer was ultra silent again! However, I was missing 6 Gigs of memory.
So shut down, put memory module B back in properly, restarted and fan noise is back (though slight subdued)
I have a temperature monitor, and the memory sticks are far from overheating. They are quite normal temperature.
I'm scratching my head on this one. There obviously seems to be a solution since it already worked once. What am I missing?

i personnally would start with some compressed air and blow all the dust out.
just last week, my fans went all jet engine on me. So i put the computer near the window and blew out the dust. Fans back to normal after that.

X-Fi Titanium PCI Express front pannel connection not working

<font face="verdana,geneva" size="3">I can not get any signal to or from the front pannel connector of my X-Fi Titanium PCI Express. (The rear jacks are working fine.)
<font face="verdana,geneva" size="3">The front header cable from my Antec P-80B worked perfectly with my onboard motherboard sound. Now that I have it connected to my X-Fi I get nothing from the jacks on the front of my case. (The onboard sound is disabled in my BIOS.)? I've double and tripple checked the connection and it is properly keyed and fitted. Is there a step or a setting that I'm missing somewhere to get this working? Can anyone confirm that the front pannel connection is acti've on the X-Fi Titanium PCI Express?

Re: X-Fi Titanium PCI Express front pannel connection not working? I was truly hoping that would help and I wanted to give you some additional hope. I have a coolermaster case, and it has the AC97 jack on the inside with all my other other front panel connectors for hard dri've activity light, reset, and power on. Three inches down from the AC97 jack, the INTEL HD *which works beautifully with the X-FI, only differs by three wires in different locations and the two pinouts configurations match those of the INTEL site identically.
Please tell me what happens as I would like to post a step by step guide for the others here in the forum. You will know when you have successfully adapted the connector because in VISTA and Windows 7, your sound applet in control panel will have a display of the connectors "lit up" when they are successfully connected. Mine shows FP microphone in the applet when its plugged in, and grayed out when its not. Its great for telling if I am connected on the rear of the soundcard of the front.
Best of luck and .......

New Build with P965 Platinum - fan connections

Question on the PWRFAN1 fan connection: Can I plug any fan into this? I was thinking of using it for the Video Card fan connection. I'm starting the build and was thinking about doing away with the Zalman cooler fan control as well as not pulling fan power from the PCI-E Power connection. There is also a Northbridge fan connection that's not being used. Can I use this one?

Well, here is the problem. The Zalman VF900 fan that I installed onto the video card has a different plug than the card. So I either hace to change the plug or plug it in somewhere else. The Zalman has the standard 3 pin fan connector, so I figure I could plug it into the Northbridge fan connection or directly to one of the PS power connections. Just want to make sure this would be a problem. Still would like to know that the PWRFAN1 connection is for as it's not indicated in the manual.

G5 won't go to sleep, plus front fan clicks

I am working on a friend's G5. It won't go to sleep. The monitor does, but not the CPU. I have upgraded the firmware, to 10.4.10, zapped the pram, corrected permissions. Just at a loss. Any suggestions?
This computer worked fine at work where she had it originally, but when she shut it down and took it home, it has insomnia. Also, one of the front fans sounds like it is scraping or hitting something. It is not a loud noise and the fans still work, just annoying to her since it won't sleep. (Sounds like my one month old).

-*, in your case,
First do a use Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. This should be done before every update.
Then,
Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.4.10 Combo PPC update. Others reading, download the combo update that applies to you! Please do the above in order.
If you still have issues work thru the following;
This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
Here is Apple doc.#303698 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Recieve Faxes On This Computer box.
If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Cheers! DALE

Lync front end connectivity test fails (SSL certificate / URL problem)

We have a weird problem in our installation where Lync keeps complaining about connectivity issues to external reach proxy on our front end server.
The event log error codes are 41024 and 41026.
Here's the error from the snooper utility:
TL_ERROR(TF_COMPONENT) [0]1A14.0EE4::12/12/2014-10:31:30.901.0000000d (DataMCURunTime,DataProxies.ProcessResponse:1197.idx(601))
(0000000001595A27)Failed poking Proxy error=[The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.], type=[ExternalReachProxy], url=[https://dunords36.du.local:4443/Reach/DataCollaborationRelayWebService.svc]
The problem is that it makes the test with the INTERNAL FQDN (dunords36.du.local) and thus the SSL trust fails as the certificate is for our EXTERNAL FQDN on the front end server! I have verified this by testing the above URL with the external address and
the internal one. With the external one the certificate is OK.
If you're wondering; we do not use a reverse proxy. Instead we just have the firewall change the port and forward the traffic to our front end server. Our lync setup is a NAT'ed setup.
I know about the security risks so this is not what the discussion is about.
I can't find anywhere where i can change the above behaviour and tell lync to make the test on the correct, external FQDN. The settings in the topology builder all seems to be OK. And as you can see it does make the test on port 4443 which in our topology
builder is configured for our external FQDN.

Hi,
Would you please elaborate your Lync Server environment (Standard Edition or Enterprise Edition)?
Please double check if you enter the correct external base URL on Lync Topology.
Please also check if the SAN of FE Server certificate correctly.
Best Regards,
