Replacement Power Supply Fan Or Whole She-bang.

A few of you may have seen my posts here recently regarding upgrades. Well, good news is that they are all in and working...fairly well. There are a few hiccups that I will be monitoring in the next week.
Anywho, something that I have determined to be an issue is that the Power Supply Fan is, for a lack of a better term, pulsating. Its running at all times but in a distinct cycle it increases and decreases in volume. One cycle is about 4 seconds I would say. I was chatting with the support people at Sonnet thinking it might be the fans on the Dual 1.8GHz processor I installed, but it wasn't. When I determined it was the power supply fan, he said he had an issue previously and said he installed a replacement fan and its worked fine ever since.
Does anyone know if Apple still offers replacement fans for a Quicksilver 2001? Or where I could buy it elsewhere? I've checked online but only find power supplies.
The power supply brings me to another issue. I have pretty much upgraded this computer to the edge. Its a 340Watt Power Supply (i believe) and I am running 4 internal hard drives, 4PCI cards (two of them are hard drive controllers), a new ATI Radeon 9800 gfx card, and the new processor. All my plugs are in use and I have one of the plugs split off into two plugs for the SATA drives.
I figured the supply was enuff, and the computer is working and doing evertyhing I need it to - well almost, i'm having an issue where Quake 4 crashes itself and the computer from time to time but thats it. But I definitely notice the fan is running louder since upgrading.
Would it be advisable to upgrade the Power Supply? Is that even possible. Online I dont seem many power supplies greater than the one I'm already using.
Thanks in advance to any help posted.

Ok.
I got a wierd problem. I am receiving the grey screen with the folder face icon while intermittenly flashing the "?" that its searching for the system folder.
So, i replaced both Case fan and Power Supply Fan. They are running fine and blowing air well. It turns out that the case fan really was the one that wasn't working well at all. It was dusty. The powersupply fan was dusty and I got rid of all the junk in there. I use the power adapters and they seem to be fine now.
However, after I put everything back together, thats when the problems started.
So, to remind....
I have 2 SATA drives connected to a SATA controller. One of these drives is my start up disk.
I have an 80GB PATA drive in the original drive slot.
I have a 200GB PATA drive connected to a Sonnet Tempo Ultra 133 Hard drive controller.
I plugged all the connections back to their places the way they were before.
Once all the power cables and connectors were in place. I plugged the power cord from the wall socket into the back of the power supply. I pressed start and I got the grey screen immediately, then my 200GB PATA drive began clicking. And then the folder icon showed up. Then the harddrive stopped clicking.
I'm also not able to eject the disc drive.
I force shut the computer down. Unplugged the 200GB drive. Started the computer, and I came to the same grey screen. Still searching for folder. I shut down and unplugged the SATA drives because I still have the old OSX.4.11 system folder on my 80GB drive. Still, grey screen and search folder.
I shut down again and uplugged the 80GB and plugged in the SATA drives. Still searching for folder.
What should I do? I tried booting into Target Disk Mode onto my laptop, but it didn't work.
PLEASE ADVISE!

Power Supply Fan Always Runs Full Throttle - Mac Pro (Early 2008)

My Mac Pro has been almost flawless since I purchased it new in February 2008. I did not purchase the AppleCare because I rather naively assumed at the time that my shiny new Mac Pro was an invincible machine. (I was seduced by Apple after all!) Well, that was when I was younger (about 2.5 years ago) and before I knew about the actual cost of things like Logic Boards and Apple Power Supplies... Now the $250 AppleCare lifeline seems like a bargain!
The Problem:
1 week after installing Windows 7 64-bit to a separate internal hard drive using boot camp 3.1, my Mac Pro was playing music from the local iTunes library in Snow Leopard when the power supply fan revved up to 2760 rpm! I immediately tried rebooting the machine, resetting the PRAM and SMC several times, but the fans continue to throttle up to almost 2800 rpm within seconds of powering on the Mac.
I have run the Apple Hardware Test several times and every time it generates the same error code within 1 loop of either the extended or regular test:
4SNS/1/40000001: lp0C-0.000
An Apple Support technician was kind enough to "sneak" me a little bit of information about the error code. He told me the message is Logic Board Sensor related and could be caused by a faulty Logic Board, Sensor Board (Ambient Board?), Power Supply or possibly a faulty sensor that might be repairable.
Emotion:
Other than my 6 month old daughter eyeing the Mac Pro with the same suspicion she reserves for the Dyson vacuum cleaner, the computer still works fine--it hasn’t crashed in either Windows 7 64-bit or Snow Leopard and I haven’t noticed any unusual behavior. I had one other problem with this computer about 1 year ago when I installed Vista using boot camp. About a week after the Vista install, the OEM ATI HD 2600 XT completely died and I replaced it with a GTX 285.
I have grown a little suspicious about the efficiency of boot camp in the Windows environment, but perhaps the 2 separate boot camp installs and subsequent hardware failures are coincidence or related to the hardware issue I am yet to resolve...?
Hopefully, someone in the Apple community will offer guidance to a swift and economical solution!
Thank you in advance for your time.

Power supply fan dead - help? (400mhz AGP G4)

Hello!
Unfortunately, my PowerMac G4, a 400mhz, AGP Sawtooth model, has a dead fan.
Over the last few weeks, I've noticed that my G4 has been running quite hot. I figured it was due to the hot dorm room that it's being used in. Then, I noticed that when it booted up, it would occasionally make a vibrating, or rattling noise - I figured the fan was wobbling. Since air was comming out of the fan opening at the top, I didn't worry about it.
Today, I used the "Temperature Monitor" widget to check the temperature of my SMART Hard drive (the G4 itself is not sensed). It was 133 degrees!!! This is the bay on the back-right, just under the CPU fan. I looked at the fan again - not much airflow. I pulled out a flashlight and pointed it in, and the Fan that's inside the power supply unit is dead.
So, how can I fix it? It's far far too hot, so it's not usable until I can cool it off. The first idea I had was to take a particularly powerful desk fan, and make a paper "tube" that connects both to the G4 and back of the fan - so it'll pull the hot air out. Needless to say, this is not a good log-term plan as it's easy to fall apart and will have leaks, but it works for now. I realize you can buy power supplies, but for ~$100, it's far too much for the old G4.
Second idea: The fan is inside the "non-user servicable" power supply, but it's also next to the back of the G4 - right inside what appears to be a panel that holds the power supply in. At the very least, I'd like to make sure that the cable is attached and not loose, but I have to open the back. Is that possible or safe? If so, can I replace the fan?
My third idea was to attach an extra fan to the inside of the G4, on the outside of the power supply - pushing in. Unfortunately, the IDE cable from the DVD drive is in the way, and there's not much room for a fan. Plus, there's no fan power supply. Is it possible to convert an ATA power plug (there are 7!) to a fan-power supply? I'd require a small circuit and a lot of resistors, obviously! If so, what would I need to do to convert it?
Thanks a bunch,
-Dan
15" 1.67 Powerbook G4 (Jan 2005), 400 mhz AGP Sawtooth G4 Mac OS X (10.4.8) 4G Clickwheel and 5G Vid iPods, 2G iPod shuffle

Thanks!
Interesting, this "Piggy back power adapter" will allow me to plug the fan into one of the ATA/IDE cables? Or do you mean the extra port on the power supply? (it has one plug for the outlet>G4, then another to support something like a monitor or similar) The G4 has a DVD burner, but no ZIP drive, so this is quite do-able if it uses the ATA power.
When you say "lower rear", do you mean at the bottom? Below the power supply, to the right of the PCI slots? If so, this is the inflow for the CPU fan! I can understand mounting it outside the current outflow-vent for the dead power supply fan, although I'm not sure the best way to proceed with attaching the fan.
Another question: what tools and supplies will I need? I may need to remove the plastic cover on the back of the G4 - the one that is outside the power supply - as there's a gap between the gray plastic and metal chassis that lets air from outside the machine come in. The screws for this cover use a funky, hexagonal screwdriver. If I need to take this cover off, what kind of screwdriver will I need? Also, should the fan not include screws/etc, what's the best method to attach it? Glue?
Secondly, to cut a hole in the G4, will I need some variety of drill? I don't have one, so i'll have to borrow one... Since there's nothing in the ZIP slot, I can run a cable out through here (assuming it's long enough), and make a new bezel to keep the airflow inside intact.
Ah! One other (somewhat related) question: my USB 2 card includes a power adapter, for use when several un-powered devices (flash drives) are attached. It works just fine with a flash drive and a small media reader, but it's slow to sense the drives - I think it's low on power. Unfortunately, this power plug uses the same variety of plug as the floppy disk drives found on many win-boxes - of which the G4 possesses none. Is there an adapter/cable for this purpose?
Thanks, this is a HUGE help, I appreciate it.

Dead power supply fan

The power supply fan on my 2002 Quicksilver Dual 1gig G4 just quit and I am obviously concerned about the ramifications. I've read a few posts in different places about fan replacements but not sure I am up to that. Does anyone have any advice / cautions about power supply replacement?
Unfortunately this is my only computer and I can't really afford the downtime if I take it somewhere. I have reasonable confidence in my ability to do the work (I've added hard drives, replaced the cd drive, ram etc.). Any tips and especially a lead on a good (inexpensive) hardware source would be appreciated.
Thanks,
John
2002 Quicksilver dual 1g G4

You'll need to remove the power supply from the computer and open it up to access the fan. Installing the new fan may involve splicing its leads to the existing ones attached to the circuit board. Beyond the fan's physical size, you need to match its voltage rating and output (measured in CFM), so that you buy a suitable replacement. The fan's noise level (dBA) should also be considered, so compare the specs on that. According to the info on this page, the fan's specs are:
Protechnic 80x80x25mm MAGIC (made by Sechang Micro)
12 Volt, 0.24 Amp
38.27 CFM, 3000 RPM (max), 29 dBA

Cisco 12008 Power Supply Fan Tray Hot Swappable? 09/10/14

Hello,
I have a power supply fan tray [PART NO. GSR8-PWRBLOWER(=)—Power supply fan tray ] for a EOL Cisco 12008.
Q: This hot swappable while 12008 is online/powered on?
Thanks,
Kent C.

Typically, when "hot swappable" is mentioned, it means that these items can be replaced while not impacting the operation of the system.
When an optics module is pulled, traffic will be impacted. Depending upon the system's configuration, the traffic will need to re-converge.
The optics modules can be installed or removed while the system is powered up.
Hope this helps.

Noisy Power Supply Fan?

I've had my G5 for 1 1/2 years and it has been a very quiet computer until a few months ago. I've narrowed the constant noise as coming from a fan at the very bottom of the computer. Is there any way to access this fan to clean or replace? I found a link to a web site that shows how to access the power supply fans on a single processor G5 but no help with a dual processor machine.

Hello, William, and welcome to the Discussions.
You've posted in the iMac G5 forum (inadvertently, I presume) which will not be the best place for advice about a PowerMac. I'd suggest you ask again in the PowerMac G5 forum where you'll be more likely to get useful suggestions.
Good luck.

Replaced power supply same problem

took my imac g5 to apple store where genius told me it needed a new power supply because machine would not turn on and when it did just to gray apple screen Even though the serial number was in the range for extended repair program, i was told mine was to old and did not fall under any repair program. I replaced power supply same issue of gray/white apple screen and fan kicks on loud. reset pram, reset smu, checked diagnostic led lights 1,2,3 all light as they should. Cannot start up with discs either. Anyone with any ideas it would be much appreciated.

What a bummer! If you can get hold of the reseller, go after him for legal discs, if you can't get him, call Apple at 800-767-2775 and they will send you an appropriate set for a nominal fee.

I would venture to say that your 3pin female adapter should be plugged into a 3pin male adapter on your motherboard. This allows your system to control fan speed on the power supply. I hope this helps you.

Power supply fan problem?

My G5 has been making this noise intermittantly - but more often - and it seems to be coming from the area near the bottom of the computer, underneath the main compartment where the processors, HD, etc are. It sounds like a dying fan or the like to me. What do you think? Is there anything I can do, or should I bring it in to Apple?

PowerMac G5 (Dual 2.3) Mac OS X (10.4.4)

I had a similar problem. You can try cleaning the fans first, but you may have a bad bearing in one of the fans. I ended up having the PS replaced.
Cleaning a Power Mac G5's Power Supply Fans >>
To troubleshoot the problem, put the computer to sleep, stick the plastic nozzle from a can of compressed air though the front grill on the lower right as the red arrows indicate to block one of the PS fan blades from going around. Wake the computer back up and see if the noise is still there. Mine wasn't, so I pulled the nozzle out while the computer was running and the noise started up when the fan started running. I knew I had a bad fan motor then and had the PS replaced. There are two PS fans as you can see in the picture, so you can test each one this way. Good luck!

The Power Supply Fan is still working, but does not appear to respond to increased loads, and its speed cannot be increased using SMCFanControl. Any suggestions?

Hi all - My mac pro 1,1 has an enigmatic problem. It's quad-core, 3Ghz, running OS X 10.7.5. The problem began some months back, when running HD video conferences, HD streaming videos and some other graphics-moderate (I won't say intense) uses, such as slide shows in Just Looking. My machine has an ATY, RadeonX1900 card and 2 monitors - both Apple displays, one being 30 inch 2560x1600, the other being 24 inch 1920x1200.
When I start those types of graphics-moderate apps, after about 5 minutes, something would crash (the monitors making a noise as it did) and the displays would both go black. The power did not appear to be fully cut off from the monitors. I think that the underlying applications, however, did not crash. So, I could still hear and speak to people during video conferences, and I could hear the sound tracks of videos.
Attempts to restart the computer and get the monitors back did not immediately work to undo the problem, if done straight away. The only way to correct the problem (so as to have the monitors work) was to wait for a few minutes and then restart.
After a lot of puzzled looking at console logs (and I confess that I am not an expert), I ran into a blank.
But, because of the timing of the crashes (after ~5minutes use) and restarts (after some minutes wait), I reasoned that the problem might be temperature related.
Once on that path of thought, I found this article:
http://worldtv.com/blog/guides_tutorials/fixing_an_overheating_mac_pro_no_expens e_required.php
I installed both Temperature Monitor and SMCFanControl. And I experimented, and got interesting results:
Now to the puzzling bit: SMCFanControl shows that the speed of the Power Supply Fan doesn't vary much, even if I use SMCFanControl to ramp fan speeds right up. All of the other fans react to SMCFanControl, going up to and above 2500rpm when commanded. But the Power Supply Fan does not. Having watched it for a few days now, the Power Supply Fan, according to AFCFanControl, never varies outside of a range from about 600-640 rpm, regardless of what I do with AFCFanControl.
Also (and not surprisingly), whenever the graphics-moderate apps run, when I ramp all the fan speeds up using SMCFanControl, Temperature Monitor shows that the all of the temperatures within the machine plummet, except in the power supply locations. Power Supply Location 2 is the worst affected. Because the Power Supply Fan does not react as the other fans do, the "crashes" still occur.
I could post some screen shots of the read outs of SMCFanControl and Temperature Monitor, although I think I have covered the key points in this post.
It seems that the Power Supply Fan is still working, but does not respond to increased loads.
Instinctively, I'm worried that if that's right, it might be a hard problem to fix. Any suggestions? Help! I would really appreciate them!
Cheers
P

Thanks for your response Grant. I had already read about, and I think excluded, dust in graphics card/fan/assembly as a cause. The entire inside of the computer, including the graphics card/fan/assembly, is as clean as a whistle. It looks clean. I've cleaned the dust out every now and then (including a few days ago). Also, my undersanding (derived from the article, linked in my first post) is that I might expect to see high temperatures in the Northbridge and memory module B if the graphics card was overheating. According to Temperature Monitor, however, locations do not increase in temperature when I run the relevant apps. Finally, the graphics card/assembly does not feel too hot to touch.
It is strange that SMCFanControl lists the Power Supply Fan as being software controllable, if that fan is not. Still, your comments are consistent with my observations, as the fan simply does not respond to software control.
There are two upsides: First, I've something of a work-around. I've worked out what temperature must be achieved in Power Supply Location 2 for a crash to occur, and I can watch that location in Temperature Monitor, terminating the process before that treshold is reached. Of course, that's not ideal. Second, ramping all the other fans up does significantly delay the onset of the problem, and makes recovery time much quicker.
Is there any donwside to peridically ramping up the other fans when running the relevant apps? Given that it causes all of the other locations to cool significantly, could this lessesn the life expecancy of the mahcine? (I don't want to run the fans up all the time - that's like sitting next to a jet ready for take off!)
Also, a correction to my first post: Yesterday, with all the other fans running on full and running an HD streaming video, the Power Supply Fan did, eventually, slowly, come up to ~740rpm, which is much higher than the ~640rpm maximum I had previously seen, and this may have aided delaying the onset of the problem.
I'm not sure where this leaves me? The problem might now be able managed. Well, sort-of. But it's not eliminated.

Apple do not sell parts for the TC..
And do not allow their OEM to sell parts.
So you need to bypass Apple and create your own.

Yes.
Memtest X or Rember to test the RAM.
Reseat is also good.

I am sure that they can point you in the right direction.
I am a little shocked that one of the Apple Retail stores can't offer you a Power Supply.
If all else fails, it sounds like you have tried an alternitve, if it works use it, until you can get a replacment.
