Can I repurpose the fans in a dead G5?

I have an old Dual Core G5 that has died. I will recycle it thru Apple. However, I removed the two hard drives (It was the logic board that died) and was also wondering if there was any way to repurpose the fans? I removed the dual fans and the one that was attached next to the speaker. What sort of procedure could I do to power these fans and use them in some fashion?

Connect the fans to a 12v DC wall wart to power them, or, wire to a Molex connector and connect them to an ATX PSU powered machine.
The dual fans from the G5 (essentially) are these:

Pins 3 and 4 are Ground and 12v respectively. Pins 2 and 6 are the tachometer leads.

Can I change the PCB of my dead Toshiba HDD?

Hi
My toshiba hard disk is dead!
Can i change the pcb of my dead hdd for one pcb of a new hdd (similar to the old hdd) ?
It will work fine?
Pleas help me, i lost all my data.
Thanks.

What HDD do you mean exactly?
Is it an internal or external USB HDD which can be connected to the notebooks USB port?
Generally speaking, if the HDD isnt accessible anymore, the HDD is dead and data recovery will be very expensive since the data recovery must be done by people and company who are specialized in solving such problems.
In case the HDD is ok and only the SATA controller is faulty, you could try to remove the HDD from current HDD enclosure and could try to connect the HDD to another SATA controller.

Can you adjust the fan speed? How?

I had an espiode the other day where the MacBook got so hot that it basically shut down. Can the fan be adjusted and how do I get to the area to adjust it? I am fairly new to the world of MacBooks and would appreciate the advice.

You can easily adjust the fan speed by using smcFanControl:
http://macupdate.com/info.php/id/23049
That said, it sounds a bit strange that the MacBook would run so hot. The fan should adjust itself to the CPU warmth. If that is not happening, I'd investigate whether the fan really works.

Can you hear the fans on iMac? (my new 2011 27'' i5 fans are constantly audible even from a distance)

I have the 2011 27'' Imac i5 and I can hear the fans all the time as of start. It's not super strong but clearly audible even from distance. istat shows normal fan speeds (1100/1300/1000 respectively) . The noise bothers me a lot especially in a silent room. The fans start to be audible immediately after switching on and get higher (+temperature rises significantly) under any easy activity .. like streaming a video from net.
Can you hear the fans on yours at all?

Do a SMC reset (maybe do it 2-3x) and if the problem persists as you have been advised call AppleCare.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Can I set the Fan manually..?

I use BOINC and because of that my Thinkpad T410 crashes quite often!
(Although I let BOINC only use one core!) Can I somehow set the fan manually to the maximum and set it back to normal when I stop BOINC?

@mBurch,
Just a suggestion ... since you leave the BOINC on when the laptop is idle, do elevate the laptop since the software is constantly running the proc up. By elevating the laptop you enable more air to get "pulled" into the base of the laptop thus better ventilation = cooler and happier laptop when you volunteer.
Juz my 2 cents =)

I have a Y2P (i5) ... Feel free to ping me if you want me to test some applications with your Y2P if you have the same model. I don't mind keep doing recovery on it if needed .... =)

Can anyone compare the fan noise level of the C2D and the G5 imacs?

Anyone owned both? Is the C2D much more quiet?

I'm your huckleberry! G5 rev b went from being pretty quiet except under load,and lately since 10.4.6 and after, the fans started spining a little faster than they use to, thus louder. I didn't mind it. Interstingly I had to unplug it (which I've done to reset the SMU) but I guess never for long enough, now when I plugged it in, it amazingly works like it did at its best, fans didn't speed unless under big load, and then would spin down again. Be that as it may, it wasnever totally quiet. The new one is virtually quiet. Right now I'm encoding video for the last 20 minutes, the back left panal is toasty to the touch the fans are working and you can barely hear it at all. Sounds more like when you here slight moving of air from airconditioning in an office. Thats it for the fans, the quietest I've ever heard on any box I've ever worked on.

How can I stop the fan from running continuously on my iMac? I have tried resetting the SMC and this did not work.

I have a 27 in. iMac OS X, Version 10.7.5, Intel Core i5 and have a problem with the very loud and annoying fan running continuously. The fan starts up immediately upon powering up and stays on all the time. I have researched this on the internet and have tried resetting the SMC unsuccessfully. Should I try fan control software?

To reset the SMC means to reset the power management settings for your Mac. To do this, follow these simple steps.
1) Shutdown your Mac by going to the Apple Logo in the upper left hand corner of the screen and selecting "Shut Down" from the drop down menu.
2) Turn your machine back on while continuing to hold down the power button.
3) After the initial boot chime, your power indicator light should flash three times.
4) Your screen will remain black and you will hear the boot chime again. At this point, you may release the power button and allow your Mac to boot up normally.
All the best with getting your Mac Mini to run smoothly.

Why is my macbook pro running slow and I can also hear the fan running continuously

My macbook pro started running slow last night. I turned it off and waited til this morning to turn it on again. It is still running really slow when I browse through my dock or apps and everything takes forever to open, my fan is also running pretty loud, I could not hear it running until last night. Can anyone help me out?

Okay so I followed those steps, what exactly does this mean?

How can I identify the culprit for a "dead" iMac?

Hi, my friend's 21" iMac ( Intel plastic, last version before aluminium ) started to boot erratically a while ago. She had to let it sit for hours, and then for days, and it would eventually boot again. Now she finally called me, for the iMac seems to be unwilling to boot at all. When I press the start button, it produces a very low noise, I have to press my ear against the housing to hear it. But no disk spinning, no light flashing, no screen. I was thinking that the power supply could be dead, since I encountered this problem on my older G4 mirror door tower. But maybe, could it be hopefully just a PRAM battery problem? Is there one in the iMacs that needs to be replaced once in a while? Is there a tutorial that could help me spot it? Since I replaced a drive in that iMac model, I suppose that I could do it myself, provided a few hints and maybe the battery model?

There are internal PRAM batteries. Once dead they can lead to unusual symptoms such as no video. But I cannot tell you if that's the case. However, that may not prevent the normal startup chime.
Getting to the battery requires substantial disassembly of the computer. You would need to do a Google search to try and find a disassembly tutorial. You could check out ifixit.com for a start.
Now, you might try:
Resetting your Mac's PRAM and NVRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
But if you cannot succeed in a normal startup of some kind, then take it in for repair as the problem may be more than just a run down internal battery.

I have used my 2TB TC for wifi and as principal backup disk for Time Machine for a few years. I would now like to begin using another external HD for Time Machine. My question is.... Can I repurpose the Time Capsule to use as storage for libraries?

For example - I plan to use 2TB TC to house my iTunes Media Library and iPhoto Libraries - permitting access from my network.

I believe based on your notes that I need to forget about moving the iPhoto library.... even though I have found in Apple support:
http://help.apple.com/iphoto/mac/9.5/#pht6d607c42
That document says.. and I quote.
You can move your entire iPhoto library to a different computer, a hard disk, or another location on your computer.
Note that none of those locations are network.
A different computer is not network.. a hard disk is a location on the same computer as is computer location.. they are saying the same thing.
Here is what apple says about networks.. which I referenced above.. and Bob referred to.
It's recommended that you store your iPhoto library on a locally mounted hard drive. Storing your iPhoto library on a network share can lead to poor performance, data corruption, or data loss.
These are not inconsistent.. you can move the library.. what you cannot do is use it from a network location.. it must be locally mounted.
And do you think the new Photos will change any of this (though presently I am still on 10.9.5)
This is what we don't know yet.. it does look like photos will be more network aware.. do you want to be on the bleeding edge and discover it fails??
You can use any drive you like locally for TM backups.. however if you plug that drive into the TC and make it a network drive then it will become super slow.. since the TC only has USB2 port. You also cannot use TM backups on a local drive and then move it to the network.. TM backs up differently in network cf local drives.
You must partition the drive. If you want to use the one and same drive for both backups and files, partition it before hand. if you mix the backups with actual data files on the same drive.. you have no backups if the drive fails.. You must have all files on at least 2 drives. For iphoto let me suggest more than 2.. since photos are irreplaceable and it is so easy for things to go wrong.. including fire, flood and theft. Make up a USB drive and park it with relatives.

My 2006 iMac has begun to run hot which often causes issues. How can I adjust the fan speed with supported software?

24-inch iMac (2006) funning hot. Used "power button while turning on" trick to cool it so we could load some software which was telling us it was too hot; it was also smellong like it was going to burn up on fire one day while running a slide show for an hour. Need to figure out how to un-do the constant-on fan and need to find "supported" software that allows me to vary speed.

There is one called smcFanControl 2.2.2 released, but you really need to make sure that your iMac's air intake vents are clean and free from dust so that it is not sucked deeper into the iMac.
To clean the iMac's intake vent:
1. Shutdown the iMac and disconnect everything from it including the power cord.
2. Lay the iMac face down on a soft towel or cloth and go get out the vacumm cleaner.
3. Usinge the vacumm's brush or cravass tool, vigrously vacumm the bottom grill and small vent under the stand.
4. You also might want to remove the center RAM cover on the bottom and carefully vacumm it out without distrubing the RAM modules.
Then next before using smcFanControl, use the iStat Pro, a Dashboard Widget by iSlayer to first check all the sensor temp's and the speed of all three fans.
Finally if it is still having a cooling problem or you find that a fans has failed, you should stop using the iMac until the problem is fixed by an Authorized Apple Service Provider.

TS1587 I tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on you can hear the fan run, but the display stays dark. Any ideas what to do? Thanks Maja

My iMac won't start up, or wake from sleep. I've tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on, you can hear the fan run, but the display stays dark. Any ideas what to do? Thanks!

Mac doesn't boot
Can you hear the fans and hard drive and see the white boot screen? Flashing question mark? The circle just runs and nothing happens? Only black screen and nothing else? These can be very helpful to diagnose the source of the problem. [1]
Flashing question mark [2]: This is usually a sign of a failed hard drive. This indicates that boot up volume can not be found.
Black screen: This is usually a sign of a failed logic board. There is no single reason for this and this may be caused by failed GPU, screen, CPU or RAM.
Circle of death/no circle/blue screen: This is usually a sign of a hard drive failure. This may NOT be a dead hard drive, just broken permissions or something
Gray screen/Apple logo/spinning gear or globe/prohibitory sign/folder with flashing question mark [3]: This could be a sign of faulty hardware but more likely a software issue, i.e. broken permissions, failed software update, etc.
[edit]
What to do
First, hold down the option key (also known as the alt key) just after you've pressed the power button. This should show all the available options to boot from, so if you have Windows installed through Bootcamp or a disk in your SuperDrive, you should be able to see them along with your OS X drive/partition. Select the OS X partition with arrow keys and press enter. Startup key combinations
If that doesn't help continue doing the steps from below:
1. SMC reset [4]. Shut down and unplug all cables including power cord for at least 30 seconds and then plug in power cord and keyboard/mouse.
2. PRAM reset [5]. Hold down option, command, P and R while booting. Start it when you hear the sound and don't let go before it reboots.
3. Safe boot [6]. Hold down shift while booting to boot into safe mode. If this works, open Disk Utility from Utilities and repair your permissions and verify the disk
4. Hardware test [7]. Insert the install disk (disk 1 in Mac which shipped with OS X 10.5.4 or earlier, disk 2 if shipped with OS X 10.5.5 or newer) and hold down "D" before the grey boot screen opens. Follow on screen instructions
5. Boot from install disk. Boot from the disk that came with your Mac. Hold C while booting. Select Disk Utility from top bar and repair permissions and verify the disk. Reboot normally and see if it works now.
6. Boot from another Mac (Firewire target disk mode). Connect the machines with a Firewire cable. Power on your Mac and press T. Select the other Mac's hard drive. Download the current OS X combo update. Run the combo update installer and select the drive that won't boot as the destination.
7. "Repair" OS X. Boot from the install disk as in point 5. and reinstall OS X. This should NOT erase any data, just replaces the system files which may have caused your booting problem. Now install the latest combo update for OS X and repair permissions on your drive with Disk Utility.
7.1. Install OS X into an external hard drive and then boot from it [8] and try to copy your data from the hard drive before proceeding. If you have done a backup recently, you don't have to do this.
8. Restore OS X from Time Machine backup. Boot from the disk that came with your Mac and choose the Time Machine restore option. This step will lose any changes made since your last backup but the system and your data will be put back to exactly as it was on that date.
8.1 Reinstall OS X. Boot from the install disk as in point 5. and select Disk Utility again. Now erase the whole hard drive and install OS X again. If you had a Time Machine backup and step 7 worked you don't have to do this.

Hi, a week ago the option of update came on the screen of my macbook pro, it then offered to restart and will not boot up. The fan is running but no screen. Please help as I have tried everything.

Hi, a week ago my macbook pro wanted to do an update, so I clicked yes, it went on to do the normal and then offered to restart, since then I have not be able to restart. I have tried almost everything. When I turn on the power button, all you can hear are the fans and nothing else. Its not very old, does anyone know what I can do as I dont seem to be able to get any support from apple.

By everything, I am assuming you have tried resetting the SMC (http://support.apple.com/kb/HT3964) and PRAM (http://support.apple.com/kb/ht1379). If you haven't tried this yet, please do!
See the following support document as well: http://support.apple.com/kb/TS1367.
The update you're talking about was the firmware update. Hopefully resetting the PRAM gets you up and running. Try resetting it 3 times in a row (hold the keys down until you hear 3 startup chimes).
