One of the fans in my G5 is squeking

On of the fans have started to squeek and it is extremly anoying, any remedy to this? can I put a small drop of oil in it or is that a bad idea?
G5 Dual 1.8 . G4 Powerbook 17 Mac OS X (10.3.9)

Which fan is it that's squeaking? An attempt at identifying the various fans by their 'Hardware Monitor' identifiers is here
http://discussions.apple.com/thread.jspa?messageID=2141231#2141231
If you are sure which fan is squeaking, and you have AppleCare, you could contact them for a replacement. If not, then just touching it lightly with a finger sometimes helps, if it is accessible. The problem with oil is getting it to the actual site of the squeak. And of it getting where it's not wanted.
A recording of a 'Drive Bay' fan (on the right of the picture, behind the silver wire guard) squeak(chirp) is here

in case it's the noise you have.

Default fan controller, or one of the many daemons for the task?

Hi folks,
I have recently undervolted my laptop using the instructions in the PHC Archwiki and it is running nice and stable. I was thinking about looking at the fan speeds to further increase the efficiency of my system the system and reduce noise. I am using an Acer Aspire 5920G.
What I am looking for is more adaptive fan settings that are more in tune with the temps of the system, while keeping the fan noise to a minimum. My fans currently come in settings that seem to be 'off', 'low' and 'full', when what I really need are more adaptive speeds, i.e. more steps. Is one of the fan control daemons a better option for my needs, or is my system firmware usually the best choice. Does anyone have any comment on laptop fan scaling?
Cheers,
Scott

Hi there,
I have the acpi-cpufreq module running which I configure through the power management setting in KDE. As I'm sure you know, it works the same way as the various cpufreq modules, but can powernowd be used to control the CPU frequency using the built in KDE tool? I always used to use powernowd when I was running Gnome, but only recently made the switch over to KDE 4.4.
As for the fan speed. My laptop fan runs well enough and there is not really an issue with the fan per se because the laptop is pretty decent. My issue is really that the CPU temps seem to fluctuate. The fan seems right when under very low load (off) and when under very high load (full), it is in between where I have the issue. It seems to stay too low for too long, then jumps to full pelt when doing CPU intensive tasks, if there were more speed increments in between, this would resulting in an overall reduction in heat and noise. What I am really asking is, does the fan speed daemon provide this?
Cheers,
Scott

MBP - Should the fan be constant?

MBP - Should the fan be constant?
I am on my 5th MBP now and this one still has issues.
Since installing upgrading the firmware and installing bootcamp the latest one has the fan on constant. I'm sure after doing this on the others I have had the fan would only cut in when it was needed.
Does anyone else notice if the fan is on all the time?
I have also found that this MBP has the mooing problem. When it gets hot I hear a fan try to kick in on the left hand side it strains for about a second and then stops. It does this every 10-20 seconds.
I also have the whining issue but I am prepared to put up with that.
I don't want to have to take this one back but it is quite annoying.

Well I spoke to apple support but they were not sure if the fan was supposed to be constant. They told me that the fan should stop when it goes to sleep and when it is turned off. Duh-!!
They also tried to get me to reset the NVRAM by going into the Open Firmware (as far as I know Intel Macs don't use the Open Firmware).
I thought Dell support was bad but these guys take the biscuit.
In the end I was told I should take the machine back again as it was under 14 days old. I just wanted to know if the fan was supposed to be on all the time.
I now have a funny feeling that it might not be the fan that is making all the noise it could be the hard disk but I am sure none of the other MBP's I had were this loud. Does anyone else's HDD make a constant noise that sounds like a fan?
I am going to go back to the apple store again tomorrow and see if the display models are as bad. If they are quieter then I will make apple change it again. I might make them change it anyway as it is still making the mooing noise from the right hand fan occasionally.

Idle Temp of 28C (82F) !!! ...but are the fans working?

Ok now that I have your attention :P
Seriously though here is my info, as no one has really posted everything about their MBP's when posting their temps.
CPU on Idle
- A cold boot (was off for few hours)
ambient (room) temp, 15C:
MBP feels like its been in the fridge and starts up with 8C cpu temp. It gets up to 15C, then 24C and stays in mid 30's after 5-10% cpu usage.
- Waking up from sleep
ambient temp, 17C:
MPB feels normal, idle temp of 28-38C.
- Has been on for several hours
ambient temp, 17C:
If I'm not running many apps it may idle at 38C/41C.
Other times (like now) 46C. MBP feels warm but not hot.
High CPU Usage
When running 'yes > /dev/null' in Terminal or ripping a CD cpu temp gets to around 75-80C. But will cool quickly once processor is idle again, to around 45-50C.
Medium CPU Usage
Let's say 20-50% cpu, this is rough guide, I get temp of mid 50's and sometimes above 60C.
(Note: I used Temperature Monitor for temps, and had usually an ambient temp of 17C, though it might be a little warmer. I also have the firmware update from factory).
Other info:
Boot ROM Version: MBP11.0055.B03
SMC Version: 1.2f10
And yes I do have a question ^_^;
Is the faint woosh on the left of the keyboard the HD fan or the CPU fan?? Many people are saying with the new firmware their fans run constantly. I initially thought this must be one of the fans.
MacBook Pro 15" 2GHz, 512MB, Week 28 Mac OS X (10.4.7) AMD Desktop 2.1GHz, 512MB, WinXP (SP1)

Those are normal temperatures.
The left fan runs at low speed even when the CPU temps are low. The fans will ramp up, with the right fan running at higher CPU temps. Even with the CPUs running flat out the fans are pretty quiet, especially compared to my old TiBook. During the Hardware Test routines you can hear the fans come on for a short time.
If sensors fail or disconnect the fans will run at full speed constantly. Several people who did the "thermal grease fix" broke sensor connections and had that problem. Speaking of which, I'm glad that thermal grease topic seems to have come to a well-deserved end.

One of my fans is very loud, while the other one is fine, is this an issue?

Hello there, Snake97.
The following Knowledge Base article provides a great step for fans running at full speed:

In order to correct the issue, reset the SMC. Your iMac should now start up and operate as expected.
Thanks for reaching out to Apple Support Communities.

Satego X200 hangs about for one second if the fan changes the speed

Hello people,
my laptop hangs about for one second if the fan changes his speed. This does not happen so often and only since a short time.
Excuses me for my English.
Thank you in advance

First thank you for your responses.
Yes, notebook hangs for 1-3 seconds. I notice this because the mouse pointer does not move in this time. And if I hear music, only monotonous sound comes out. If the processor is busy, something like that does not happen. Only if he is idle. It is astonishing that notebook hangs if the fan goes on. I cannot ascertain, with the turning on which fan this passes.

Is this CPU fan or graphics card fan?
Yours sincerely

Own two T430 notebooks, one has noisy fan, the other has a silent fan

Hello there,
I have owned several ThinkPads over the years and recently purchased two T430 laptops - one for travelling and one for my girlfriend for school. I was aware there has been a fan issue as it has been documented all over the web, but I purchased anyway to see how the dice would land. Well the dice have landed and I have one silent computer and one noisy one. I am not too surprised by this because I have read in forums that some owners do not know what others are complaining about.
I believe this is a hardware problem and not firmware. The BIOS updates will only change the fan speed at given temperatures and are not able to reduce noise at a given fan speed. The quiet T430 is running with the 2.09 BIOS (10/19/2012). The other T430 has been updated twice and is currently running 2.54 BIOS (4/22/2013) and is just as noisy as before. Both T430's have the same fan speed at idle, just one is much noisier.
It is not very common to own two T430's to be able to directly compare noise levels, especially nearly identical configurations, but I do:
#1: T430 with i5-3320M, integrated graphics, 1366x768 LCD, 4GB RAM, 500GB HDD, W7 Pro, Finger Print Reader.
#2: T430 with i5-3320M, integrated graphics, 1600x900 LCD, 4GB RAM, 320GB HDD, W7 Pro.
#1 is noisy, #2 is silent.
I also own a W500, T410, and W530 and have had them all running next to each other at once to compare them. The T430's are the loudest at idle (including the "silent" one) and have the most air flowing through them, but the T410 is close behind. The fan noise is pretty quiet and acceptable for the T430 #2 and the T410. The W500 is extra quiet and the W530 is so silent it requires close inspection to determine if the fan is even on. Anyways, I have two very different performing fans in two nearly identical T430's. BIOS updates do not affect the sound - it must be hardware.
I am going to call technical support and request a new fan assembly for the noisy T430. This post is meant to get the attention of Lenovo and all the unfortunate noisy T430 owners. A quiet T430 does exist and I am going to attempt to make a noisy T430 be quiet. I will update this post through the replacement of the fan to let everyone know how it goes. I have read people have replaced their fans as many times as twice with no improvements - I will inspect the chassis and neighboring components during replacement to see if there is anything causing a good fan to be noisy. I am optimistic that I will be able to fix this.
If you have had success repairing a noisy T430 fan, please share how you repaired it. Otherwise, stay tuned as I attempt the repair and provide updates on my progress. Thank you.

Hello everyone,
I called Lenovo Support after starting the thread and learned that they do not send out parts like fans or motherboards for warranty claims. Instead, I had to sent my computer into Lenovo for repair. It took me a couple weeks to find time to wipe the machine to remove any personal data, but I finally called support and had them send me a box to ship it back to them. The box was overnighted and arrived the next morning. I dropped it off at a local UPS store Monday morning and my computer was shipped back and delivered two days later on Wednesday afternoon. Much faster than 7 business days they quoted.
The T430 was finally unboxed today and I started setting it back up. The fan assembly was replaced and they also replaced the cracked power port. I am happy to report that the dice landed in my favor, and this fan is just as quiet as my other T430.
I am a little disappointed that I wasn't allowed to replace it myself, but I can't really complain... Sending it back to Lenovo to get repaired under warranty fixed my fan within 3 days. There is a chance this might not work for everyone since this seems to be a intermittent hardware issue, potentially from one of many suppliers of the fan, but you can probably keep sending it back to Lenovo until it comes back quiet.
I would like to mention that the little fan noise that my quiet T430's make is a little odd sounding. The first stage fan speed is the one that sounds the most odd (the sound of air rushing out at higher speeds muffle this subtle sound): With my ear 1 inch away from the exhaust of the fan on the left side of the machine, the fan sounds like it is rubbing on something, producing a noise similar to noisy brushes on a DC motor or "white noise." (it is hard to describe). But the really interesting part is when the machine has been idle and the fan kicks off, the rubbing sound suddenly drops off, as if there was a brake on the fan. My W530 and W500 produce a "normal" fan sound that gradually changes as the fan speed changes. This rubbing sound in the T430 is a little concerning and I am not 100% confident that these T430's will stay quiet over time. Luckily I have 3-year warranty on these T430's, so I won't get stuck with a loud fan should they become loud.
I hope this helps some of you out there. I am sorry I wasn't able to look for the root cause of the noise issue (didn't want to void my warranty), but Lenovo will attempt to repair a fan noise issue by replacing the fan assembly and they do it in a timely manner.

Qosmio X300 - One of the two fans rattles abnormally

This started about two weeks ago.
One of the two fans under the laptop rattles abnormally. If I tilt the laptop for a while the rattling stops... but it's embarassing in the very least to have to do that on such an advanced laptop.
Sometimes the rattling stops when the fan's been running a while...
So anyone else had this issue? I've got next business day on-site support but would need to take a day off work if I want them to come out so am tryin to avoid that.
Aanyone had the issue? If so how was it addressed?

right... Toshiba sent someone out today.... and guess what... Toshiba managed to mess the whole thing up!
The way support works (well my understanding of ti following the disaster today) is as follows:
1) customer logs call with Toshiba
2) Toshiba order parts necessary and contact a support company that is not actually a part of Toshiba, but is contracted to carry out support
3) support company replaces parts as necessary
so, i 1) called Toshiba they told me they'd send someone over with 2 cooling fans, 2) they ordered two thermal conductors for the graphics boards (NOT FANS, JUST THE METAL PLATES!!!), 3) support guy came, when i told him what the problem was he was surprised Toshiba gave him thermal conductors and not fans. so we called Toshiba and logged a new call
i had to call Toshiba and log a new call... however, i insisted the operator note in the call records that this is the second time i am calling for the same issue as the first time they gave the poor support guy the wrong parts. now my contract only supports next business day on site visit.... as it's not practical for me to take this laptop with me to work i took a day off to be at home.....
Now that means i'll have to do it again,... so i think, hang on, Toshiba offer 24/7 on site support, so i'll ask them if, as it was their fault, they'll send someone over the weekend. "it's not within our power to do that" toshiba said "you'll have to contact the engineers company and ask them if they'll do it"... i didn't make the mistake, why should i ask?
The engineer didn't make the mistake, so why should his company have to be generous and give me a free day on site on a weekend?
Toshiba made the mistake, they should pay the engineers company to have him back on a weekend.
that is what i shall be arguing on the phone tomorrow (to Toshiba and not the engineering company) when the engineer calls up and no doubt says Toshiba are only paying for me to have a monday to friday service.
A customer should not have to worry about who Toshiba award their contracts to.
Oh, and on the matter of the fans themselves, the engineer took them out, he could find nothing inside... i tapped the fans and am very sure one of them is a lil loose although the engineer didn't think tha should be causing the level of noise he heard. however, he stood there and did hear the awful noice it was making, as if repeatedly scraping against something as the blades rushed past.
So... more updates as soon as possible... but Toshiba really screwed this one up and it's cost me a day of my annual leave... thanks Toshiba.

Try an SMC Reset. (System Management Controller)
Shutdown>unplug from power for ten minutes>press and hold in the power button for ten seconds>startup again.
Also try a PRAM Reset. (Parameter RAM)
Shutdown. At the bootup chime, hold down CMD-Option-P-R together, wait for two more chimes, total three, then let go of all keys to finish booting,
If this doesn't do it, run the Hardware Test in Extended

MSI GF4Ti 4200-TD64-the fan is to loud..

Hi all.I put together a a system thats really quiet but the fan on my msi gf4 ti 4200 is really making noise.Anyone else think the same of their msi gf4 ti 4200 cards?Well today im gonna buy the Tt GF4 cooler and see if its less noisier and it comes with memory heatzinks to.The only con is that the tt gf4 fan has 3 pin connector but i have a free connector on my mobo.Any one have the Tt gf4 cooler-is it any good?

Well,i sold the msi gf4 and bought a 128mb gf4ti4200 from Leadtek,winfast A250 LE TD My Vivo Edition.

Fan Error Lenovo T500 T510 T400 T410 T60 T61 - rejuvinating the fan

I finally got that dreaded "Fan Error" at boot time on my T500. After some research on this board, this is what I have concluded:
1- hit Escape, and the machine will boot. It can do a lot of stuff without a fan turning. Gaming caused it to overheat. Either the processor would slow down (by being intermittant) or you get the black screen of death.
2- It is relatively easy to follow the Hardware Maintenence Manual and remove the fan and heatsink assembly. Once the assembly is removed, pry open the fan, and remove the blades and clean and lubricate the shaft. My fan restarted, and the Fan Error went away. No need to replace the fan.
3- Unfortunately the machine overheats now (black screen of death), even though the fan does operate. I traced this to a too liberal application of the thermal joint compound. Made the compound a very thin film, and that seems to have helped. Also when replacing heat sink assembly and before bolting it, wiggle it while pressing on it so the thermal joint compound spreads itself at the surfaces of contact. This seems to have helped.
Anything else that you may want to add to this thread?

Thanks a lot! It makes sense.
Yes, I have been using the ESC bypass for some time, untill I really could not stand by anymore--the over heating.
I am thinking about manipulating the fan 'manually', if it could pass the booting, very good; if not, it's not completely unacceptable to run a small program@startup along with the work.
Not ready to say bye yet, will keep trying.
Thanks again!
So if you hit ESC, does your fan work normally, or do you overheat? I had the impression that your fan would work normally if you hit ESC.
My fan was always a problem on the T500 (not on my new W540). It was extremely noisy and was constantly on even at no load times. So I opened the laptop and cut one of the 3 wires on the fan (I am sure it is a power wire), and installed a manual switch. So when the thing overheated, I could manually turn the fan on. This worked for about a week and then something gave up, and the fan stopped working altogether. (don't fix something that is not broken!) I had to take the front cover off, and place a PC fan in the top left corner to cool the radiator. This was not as effective as the original fan, but let me do my job. Then the loose switch on this ersatz fan one day accidentallyshorted the fluoroscent backlight PC board of my display and I lost my display backlight! I had to pry open my display and using two 60W bulbs project light to the back of the LCD so I could read the display! This is when I decided to punt and ordered the W540. The fan is quiet and works when it has to work.

Getting rpm values from the fans on the MSI NEO2-FIR motherboard doesn't work

I currently have 6 Noctua NF-S12-1200 120mm fans spinning in my computer but i am unable to get rpm values from them except the cpu-fan. It doesn't work to get a readout from the others with either, BIOS, Dual Core Center or Speedfan. Regarding Speedfan is it true it don't support the SuperIO Chip on the Neo2, the FINTEK F71882F? It's not currently listed in their supported temperature sensors list.
So whats the problem? Shouldn't atleast DualCore Center atleast show the rpm's from the other chassis fans?
Or the fans don't support sensor readings?
Thanks!

Quote from: Jack on 13-October-10, 00:15:36
Well, there is nothing that can be done about. SysFAN 1 & 4 support sensor readings, #2,#3 and #5 don't. You can also see that in BIOS Setup. #1&#4 are the only ones that show up there (H/W Monitor section). This is not a malfunction or a bug. You have to live with no fan sensor readings or be creative about the wiring.
The problem is that i use the UNLA cables from Noctua which half the speed of the NF-S12 fans i run with. And it blocks the rpm readouts in Speedfan and BIOS.
http://www.noctua.at/main.php?show=productview&products_id=5&lng=en
Strange thing is that the CPU fan reads fine with the ULNA cable attached but the SYSFANS will not read the rpm with the ULNA cables.
What is wrong?

I have a new Macbook pro, about 2 months old, and at times running video, the fans starts and does not stop. how do you get it to stop.

I have a new Macbookbook, about 2 months old, and at times running video, the fans starts and does not stop. how do you get it to stop. Also i am thinking once the video is done the fan should be slowing down and getting quiet on its own.

Your fan(s) will run at high speed (i.e., loudly) while video is playing, and you can't get around that.
If your fans are not slowing down within 2-4 minutes after CPU- and/or GPU-intensive usage ends, and the application that was showing the video is still running, Quit that application. (In fact, if you're accustomed to Windows, you may not realize that simply closing a Mac application's window does not quit the application. You still need to use the Quit command in the application-name menu. There will always be a bright dot beside or below the application icon in your Dock for each application that is open.) Quit the ones you aren't using, and see whether that allows the fans to slow down without restarting the machine. If that doesn't do the trick, reset the SMC:

How do I clean the fans on my 2011 macbook pro 13inch

I have a early 2011 macbook pro 13 inch. It travels with me every where I go. I have had the computer almost three months now and have not had a problem with it. Some how, debris got in to the fans. I am thinking it some how got sucked in to one of the intake vents. I hear it (not often) ratteling when I move the computer or tilt it ECT. It sounds like somthing is blowing around in the fan. It is a scarry sound. At first I thought it was the hard disk. I know it is not the hard disk because I was listening to the computer when it was making the sound and it is comming from the back end of the computer, nowhere near where hard disk is located. My question is, How do I clean/ remove the debris? should I be concernd? other than that the computer runs normaly

Personally, I wouldn't touch them directly. Use a vaccum (don't use one of those compressed air cans) to vacuum out all the stuff/dust/hair/etc. Do not try to remove them. Do not try to shove a stick or something in it.

One of the fans in my G5 is squeking
