IMac G5 17" Lower Fan Noise / DIY

hi,
my imac rev. b makes loud fan noise, the lower fan (cpu?) should be replaced i think.
I try to order it by the apple diy program, but when the drop down menue appears where i must select it, there is nothing to select. so i can not go on ordering the fan.
chat agents and phone support are absolutely unwilling to help me with that issue.
what can i do? is there anybody out there who managed it to order a fan kit?
I tried it with all browsers i have on my system, i will not work

I have also had problems with a sound, more like a high pitched noise. I have had the fans replaced and a new mother board put in by Apple. (I have Apple Care and they have been great.) I had the computer down to a genius bar twice. The second time they did a re install for me. It seemed to fix things for about a week. I'm back to the noise being louder. (It wasn't like this when I first purchased the computer in Dec. 2004) This has all started in the past couple of months. Now I am back to the fans going full blast.(Just reading mail will start it going.) I put the computer to sleep, it stops. When I wake it up, it starts all over. I have to shut it down for a few minutes and then start up again. That solves the problem. The noise gets so bad it can be heard throughout my home. It's getting annoying. My next step is to ask Apple to replace my computer with the latest one that has come out. I'm still sold on the Mac and love it. I'm trying to maintain a positive attitude about getting it fixed.

MacTel iMac and the dreaded fan noise...

a buddy of mine bought an iMac G5 2 Ghz last June and mentioned having no problem with the dreaded fan noises of said iMac. fast forward to last week when we got together to do some nerdy stuff in front of same iMac when he casually mentions to me. "my fans have been going crazy lately" ... not that his iMac sounds like a jet turbine or anything, but it got me thinking about the new "Intel Inside" Macs. and with two cores inside, goodness!
so b4 i rush out and buy one of these babies -- i'm going to wait and see regarding the fans. but it will be interesting to see how all of this plays out.
CMM.
PS.. i am a bit amazed (and elated!) that the Intel Inside Macs have already become a reality -- 6 months sooner than expected. (who would have thought!)
YAY!

Miriam,
Maybe I was a little premature. I just went to abc.com to watch the last episode of Men in Trees and here's the results.
With ABC video running (maybe quarter screen size), the CPU was running at a steady 65-70%, CPU temp 69.8, CPU fan 4791-4814 steady (very loud).
Didn't seem to be a high bandwidth download as net was clicking at 117 Kb/sec.
Oh well...don't really consider this very good performance. The fan went down to the 2700 range on reduced, but then the video was choppy. Good thing my capacitors are leaking...Maybe I'll get a Core 2 under my 3 year Apple Care.

IMac G5 bootup with fan noise but no display

Hi all the experts out there,
I'm new to iMac and need help to resolve the following issues:
1) My iMac went on sleep mode and follow by a big fan noise.
2) Able to power down but when I press the power button follow by the Command, Option, P and R keys, no response from the iMac (no screen display but power indicator is lighted)
3) Anyway to eject the Disc manually from the slot? By pressing the eject key from the keyboard does not eject my CD. I'm trying to eject the music CD from the slot, so that I can put in the system disc to try on other mode of recovery.
Any help is welcome.

My iMac monitor makes a "fan" noise that won't shut off. What is and how do I shut it off

My iMac monitor is making a "fan" noise. What is it and what do I do to shut it off?

Fans run to stablize temperatures on your iMac. The fans cannot be turned off.
If you think the fans run excessively, try Resetting the System Management Controller (SMC)

21.5 iMac i3 3.06 fan noise

Hello all. I am a longtime Mac user (going back to the first LCD iMac.
Anyway... I ordered the new base iMac and noted that it's fan was on all of the time and was quite loud. It always felt very cool to the touch. I assumed that was just the new reality with the intel processors (my last mac was a 1.5 gig g4 powerbook 12).
I ended up exchanging that computer with a new one since it had the yellowed screen (bottom right).
Anyway... the screen on my new iMac is great... but now the computer is dead silent. The back is pretty darn hot too.
Just wondering what the norms are? Most temps are in the 50's... and the GPU is in the low 60's.

Hello, I think it could be two things: one, the fans are very revolutionized or there's a problem with the GPU fan and the HD cable. I'll explain: My iMac was very noisy, I called Apple and they said me that I have to give the computer where I bought to change it. And the problem was that the HD cable wasn't in their place, and it was touching the GPU fan.
PD: Do you try to reset SMC? (http://support.apple.com/kb/ht3964)

IBook or iMac? Fan noise?

Hey, I am thinking about getting either an iBook or an iMac.
I have read that the iMacs make allot of fan noise? Is this so? That might be a problem, as I will be using it for recording guitar and vocals quite often.
Anyone here use an iMac to record stuff in garageband?
Cheers
see ya

my G5 iMac sits in the only room in my house that does not have AC and even with the processor averaging about 165*F I barely hear anything over a purr. the room is a sun room, and I live in Santee, California, which isn't exactly cool during the day if you know what I mean. the SuperDrive is the biggest improvement, even though it is audible during use, my old G4 used to sound like it was trying to take off like a turbofan engine. while the heat of the thing scares me a little, I feel confident that it can handle it. I've not really tried to max it out, but in a room that averages 85+ degrees during the day she's holding up well I never used my G4 to record in garage band, but I've made simple techno songs, just by clicking with the mouse, and adjusting things, it took for-freakin-ever to do it that way, so I will be getting better equipment now that the new imac can handle things better.

2 years of this fan noise....check my temperature?

so i've been battling the dreaded imac g5 (first gen) fan noise for the entire 2 years I've had the computer now. one midplane (out of 3 now? 4?) almost fixed the problem, but it had other problems. For the past year I have just let it go as it was in a room with a noisy window air conditioner and a noisy PC. Now I've moved and am back in a quiet room and the noise is unbearable.
Took it back to the apple store but they said it wasn't noisy (and it seemed less noisy there, not near as much "whine", but that could have just been all the ambient noise as well - music, crowded store, etc)
but my real question here is what temp should the imac g5 (1.8ghz) run at? at idle my CPU usually sits at about 155, under load about 165-170. this is acceptable right?
maybe its just a sign to give up on this machine and be an early adopter with the new mac pros and get to deal with whatever engineering probs are there (had the cube before this, bought right when it came out, cracked case, flaky sensor, temp problems, etc) or learn my lesson and wait another 9 months or so
I'm also having USB problems, but Apple told me they couldn't replace it (logic board) because my headphone jack is broken and that part isn't under warranty even though the USB is. sigh

Hi Eric, you might get more help posting in the G5 forum. This forum is for the iMac Intel Core Duo.

IMac i7 - Strange CPU-fan problem!

Hi,
my name is Chris and I'm living in Germany. Sorry for my pigeon english, I'm not very good in languages... Nevertheless I will try to describe my problem.
I have received my iMac last saturday. It's an i7 with 2TB hard drive. On sunday suddenly the CPU-fan went nuts, spinning with about 3500 rpm. At that time there was no heavy CPU load at all.
Neither P-RAM- nor SMC-resets fixed the problem, the CPU-fan was running at full speed all the time. On monday morning (the i7 was switched during the night), the problem was still persisting. Hence, I contacted Apple and they promised to send me a replacement for the i7 in about three weeks.
Later on this monday, I received a package with additional 4GB of memory I had ordered for the iMac. Although the iMac was making noise comparable to a 747, I decided to build in the additional 4GB of RAM, just to play a bit around with an "8GB machine". The assembly of the additional memory was pretty easy, basically everything was working fine (memory wise). But the CPU-fan was still continuously at around 3500 rpm.
Afterwards, I decided to clean up the computer a bit by using the "automatic" script within "Onyx". I started the procedure and left the room.
When I came back about 1 hour later, there was total silence in the room. In first instance I wasn't surprised very much, because the iMac was obviously in the sleep mode. But I was really surprised when I woke it up again: The CPU- fan was back to normal, spinning with 940rpm. Almost completely silent.
Any ideas what happened? Can there be a connection between the "fan-went-nuts-issue" and the Onyx scripts?
What shall I do? My iMac is behaving now, but I have already ordered replacement...
Best wishes,
Chris

Yes, I have seen this thread, thank you.
When the CPU-fan started to spin at 3800, one of the first thing I tried was putting the iMac into the sleep mode. After I had done so, I woke it up back again almost immediately (about 1 minute later) by pressing the space bar. But for some reason, the iMac woke (with normal fan noise) and then immediately fall back into sleep (after being about 10 seconds awake). A "proper wake up" was not possible, since it was sort of an infinitely loop of waking up and falling asleep. A reboot via the power button was necessary, whereby the fan went back to 3800 rpm.
And then I performed this Onyx-run (as mentioned in my first post), and afterwards the iMac went to sleep mode automatically. It stayed in the sleep mode for about an hour or so, and after my next wake up call it was cured.
Really strange. Either it was cured by the maintenance-things Onyx did to the cache/system files, or by being in the sleep mode for about one hour. I also can't exclude influence of our Lord, since I was behaving in the last year...
Somehow I have lost my trust in that machine. Even after the fan went back to normal behavior I am still not sure if I should cancel the replacement order... I am open for recommendations from your side.
Best wishes,
Chris

Probook 6360b: Permanent fan noise

Hi all,
I have bought my Probook 6360b a few days ago and I like the performance and the sturdiness of the body.
However, the constantly buzzing fan is annoying me now already.
The quick facts:
- I have disabled 'Fan always on while on AC Power' in the bios (bios version F.03 (27 Apr 2011))
- CPU usage is <5%, CPU temperature is < 100F / 38C
- Power consumption is 8-9W (according to 'HP Power Assistent')
- SSD hard drive (i.e. no hard drive noise)
Basically, the fan is pretty silent; however I am working in a (very) quiet environment where I can constantly hear the permanently buzzing fan, which has become annoying after just a few hours.
Is the permanent low fan noise considered 'normal' for the Probook 6360b?
If so, is it possible to reduce the noise even further or switch off the fan at times of low CPU usage?
Thank you in advance for your help!
Chris

Hello RobotWong
Welcome to the HP Forums I hope you enjoy your experience!
I am sorry to hear that the fan in your HP Probook 6360b has become as loud as you have described. I have a couple of ideas to assist with this issue,
First, this is probably the most important part of my post is to ensure you are not overheating. To do this I am posting the HP Support document: Reducing Heat Inside the PC to Prevent Overheating. This document was designed to help prevent overheating, and according to the document one of the symptoms of overheating is "Fans inside the computer become louder because they are spinning faster to remove the heat". Be sure to review this document and ensure this is not the case.
Second, I am providing you with another HP Support document: HP ProBook 6360b Notebook PC Maintenance and Service Guide. If you refer to page 74 you will see the part number for the fan as well as instructions on how to replace the fan. The fan can be ordered from the HP Parts Store. Now I am not saying you need to replace the fan (it is an option), but I would advice cleaning out the Thermal Paste and replacing it with a good quality Thermal Paste. This can get contaminated with dirt and dust and not glide as smoothly over time.
I believe if you follow the advice above you will resolve your excessive fan noise. Thank you for bringing this issue to the HP Forums. Have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!
Also be sure to mark my post as “Accept as Solution" if you feel my post solved your issue, it will help others who face the same challenge find the same solution.

Worrying about iMac with Logic Pro. (i mean big fan noise)

hi.
i am thinking about buying a new iMac with Apogee Ensemble. but i am a bit worried about the fan noise from imac when i use lots of plug-ins and etc.
well... the best way is to buy a Mac Pro and stash the machine in a machine room or a cabinet or something. but the budget is low here.
does anyone have any good ideas? do i have to take the fan noises? or is it really so powerful so that makes no such big fan noises?
thanks

I have no doubt that you and I haven't been reading the same posts, but I was under the impression that most people were much more infuriated that there was no announcement or run up to the launch (and thus they bought L9 just before).
Actually, we have been reading the same posts! Apple, historically, have never (and I do mean NEVER) pre-announce releases of Logic Pro. They are always announced on release day, even going back to before the Mac App Store, when boxed versions were still available. Apple do have quite a generous refund policy, so I suggest that anyone who feels cheated could always 'report an issue' via the link in the receipt email and try and obtain a refund. Personally, I would never buy a current version of Logic Pro until July was over, but as I've been using it for over 11 years now (before Apple bought Emagic), I guess I'm very familiar with the release times.
So why not keep support for EXSManager/Keymap, or at least a download link for paying customers. There is no other program that can do what it did unless you want to go back to an old version of Logic and utilise functionality that they removed yet is still relevant today.
Redmatica wouldn't have been allowed (under the terms and conditions of the buyout), to keep making the EXSManager, it would have been illegal as it's now an Apple product. That's like saying why didn't Emagic keep making a version of Logic for the PC after Apple bought them, because they obviously weren't allowed under the terms and conditions because it became an Apple product. While I can understand your frustration, you also have to understand the legalities that take place during takeovers and buyouts, as it's really not as simple as it may at first appear.

Fan noise on Macbook pro retina 15 on low speed!

Hi guys, I'm experiencing a constant low background noise from the left fan (as I'm looking at the screen). The noise is audible always even when the fans are working in their lowest speed possible the noise is there. It seems to me that that is a mechanical failure of the fan itself. It's like something is touching at the fan. When I'm slightly moving my laptop the noise is exaggerated seems like the rotor is going out of place and touching the surrounding structures. I bought the laptop on December and I didn't use it too much. I'm having a similar problem with my older MacBook Pro but the noise from the fans occurs only when I'm moving the laptop vertically and after five years off continues usage. It's anyone having a similar problem? Any advice? Should I replace the fan? Or should I take it to an authorized service?
MacBook Pro (Retina, 15-inch, Late 2013)
2.3 GHz Intel Core i7
16 GB 1600 MHz DDR3
Intel Iris Pro 1536 MB
Thank you in advance

If it is under warranty, by all means take it in for service. If there is a mechanical deficiency, it should be repaired gratis. It does sound like an internal fan problem that needs to be replaced.
Ciao.

TA25225 Display Flickers in my 21" Imac Intel. This happened after the fan noise in my machine. I also reported the problem and gave to the service centre, but the problem still persist. Please help. I purchased it 3 - 4 weeks ago

Hello,
I purchased my imac intel 21" 3-4 weeks ago and in the 2nd week i faced an issue with the machine. When i switched on in, there was a fan noise and a white screen. The machine had hanged. I reported the problem and gave to the service centre. After testing for a week, they said that there is no problem with the imac. Again i faced the same problem after receiving it from the service centre. They again tested the machine for 3-4 days and reported as no problem with the machine. Couple of days back, I received the machine from the service centre, and on the same day when i switched it on, there are flickers in the display. Please help me solve the issue. I am from India. The service here is very bad.
Hope for a resolution
Thanks

Hello RedDevil07
Yes I agree with seventy one. It's common sense to do this, especially now. I would also contact AppleCare and report this issue with them, it will get documented and you will have a caseID that you can refer to when talking to them in the future should this issue go one.
Be polite with AppleCare and your AASP. Hopefully everyone is being honest and trying to help you and not what might appear to be the opposite.
Patience is a virtue, but I thoroughly understand your frustration.
Let us know how it goes, we are here to help in whatever way we can.
I encourage you to contact AppleCare to report this experience and get their recommendations. There is an expectation that you should have that AppleCare is there to help you as a customer. I am sure they will too!
