Quiet Cooling Fan

Does anybody know if apple make a quieter cooling fan for the eMac cos mine is pretty loud and keeps everone awake at night!!!

Hi Creds,
Sorry to hear that your fan has become louder over time. Unfortunately that's been my experience with every single fan I've ever installed (mainly in desktops). I guess bearings wear out. I've only been using my T500 for a few weeks now. I've been debating whether to let the fan run as it likes or to take software control over it and run it less often. The fan is so quiet that until now I've been content to let it run, but if I can prolong its quiet life by running it less often I might do the software control thing.
A couple of thoughts about your T500: Are you sure it's the fan that has become louder and not the hard drive? Those tend to get louder with age too, unfortunately. And I saw in another thread that you're asking where the fan exhaust is: it's at the back left. I think the idea of blowing compressed air in there is to clean the cpu heatsink you can see right inside the vent.
Which CPU do you have in your T500? You could try undervolting it to bring down power use / temperature / fan speed.

GT80 Titan Cooling Fans are on frequently than before

I just purchased the new 18 inch Titan and love it. However, I just started noticing the that the fans that use to come on infrequently and very quiet are now coming on more frequently. I have a cooling fan that sits underneath laptop there is nothing blocking or constricting the air ways. The laptop is turned off longer as I returned to a longer work day, and the temp in the home is in the low to mid 60s.
Is this something I should be worrying about? I have been frequently using the air duster on the laptop. Oh, I have only had the new monster machine for about a month.

Hi, how about updating BIOS and EC firmware to latest version?
Also maybe you have installed some resident programs in the background? Anti-virus and Windows auto update would also work in the background.
You can try to recover the OS to factory default and observe its status.
Using Shift feature to switch to Green mode might do some help when you only at office mode.

Vaio E series - Cooling Fan noise

Hello, 2 weeks ago I bought Vaio E series. I was very excited that I will have Vaio laptop. It was like my dream wish. According to our standard, we are poor country and the Vaio laptops are extremely expensive. But, Vaio laptops are know for high quallity laptops and great support from Sony. So, I bought it. I am very satisfied with the quality. But I have one problem. The cooling fan is making a lot of noise even the CPU usage its 10 %. I have the latest BIOS version. So, Sony I am expecting from you to release a new BIOS update fixing this issue.. I dont want to start thinking that I pay a lot of money only for the name. With that money I could buy a more powerful machine but I put my trust in Sony. The model number is Model # SVE17122CXB. PS. Don't say that I should go to service center because they can do nothing. I am an IT student and I know how this stuff works. And I dont want the fact that the new laptop will be repaired. So the only solution is BIOS update. Sony, do not make me regret that I have chosen you before other brands.
I am expecting a positive feedback.

t0n1,
Engineering came back saying that fan speed control is not supported on the SVE17 hardware so there is no way on this model to control the fan speed manually. I apologize for suggesting this initially, at the time I did not have your exact model at my desk but instead I had a very similar one (SVE14A)
I also received two SVE17 notebooks and both have extremely quiet fan (especially if CPU usage is very low). Loud fan noise is not a characteristic of this model.
If you feel that the fan on your SVE17 is abnormally loud, then you have two options at this point:
1) You can make a audio/video recording of this fan noise and post it for me to review; after that i can try to give you more suggestions or let you know if this is in fact normal or not. At this time you do not mention that your computer is shutting off, so the unit is not overheating.
2) Or you can consider service. (I realize you initially refused service in your original post, but sometimes some new thermal sheets or re-seating of the heat-sink can address these issues.

RADEON 9800 cooling fan

I have a RADEON 9800 Pro Mac Edition 256MB in my QuickSilver 2002 mounted in the AGP slot. The 9800 cooling fan is very loud (grinding sound) after a cold startup then gets quiet after it warms up. I have looked at third party cooling fans for this RADEON and I have found the Zalman v700cu and the Arctic Cooling ATI Silencer 1, Rev. 2 that seem to be compatible. From the images of these two coolers it looks like the two mounting screws that project out the back of the garphic card are very close to the lower memory slot in my QuickSilver. I don't use the PCI slot next to the AGP slot so I know the coolers will be OK there.
My question is, has anyone actually tried one of these coolers in a QuickSilver 2002 and is there enough clearance between the mounting posts on the cooler and the memory card to prevent them from touching?

ATI fans are notoriously bad (read that as cheap). You will know the fan is going bad when you hear a loud whine or grinding noise after a cold startup or during heavy use. The fan went bad on my 9800 Pro 256 after just 5 months. I had to send the card to ATI for repair - nearly 3 weeks to get the card back. The replacement ATI fan started making noise after another 90 days. I can't see doing this on a regular schedule for the three year warranty term so I replaced the stock fan with an Arctic Cooling ATI Silencer 1, Rev. 2. It's easy to install. So quiet that I can't hear it run and my computer case and power supply fans run slower and with less noise than ever before due to the Arctic fan venting warm air out of the computer.
The Arctic Cooling ATI Silencer 1, Rev. 2 installed perfectly with no modifications and minimal effort. It has a 6 year warranty. I consider this modification the best thing you can do to protect the $250 (or whatever you pay) investment you make with the RADEON card. It's better than waiting for the stock fan to fail and cause your 9800 to melt down. Technically installing the Arctic fan voids the ATI warranty but I believe I could reinstall the old stock fan if the card needs other warranty repairs without anyone noticing the switch was ever made.
So your answers are yes and yes although I never had the monitor problem you describe. The ATI card is a good choice - keep it then download and install the latest drivers from the ATI/AMD web site and do yourself a favor and buy an Arctic Cooling ATI Silencer model for your card. Install it when you start to hear the stock fan going bad. You will be glad you did.
PS - many thanks to FangSuede for his excellent advice given to me.

Mac Book Pro Core 2 Duo Cooling Fans running at 6000rpm

Hey everybody.
Need a little help/advice. I bought a MBP 17" C2D back in June and now the cooling fans turn up to around 6000 rpm minutes after turning on my notebook. I've tried SMC fan control, which didn't work. I searched for a stray program, but nothing turned up. I am trying to avoid having to drive to the Apple Store (I will if I have to), but wanted to see if anybody else had a suggestion. Any feedback is appreciated, bigtime. Everything works normally too, all my programs, my wireless card, etc. Leopard installed in a breeze. Thanks in advance for the feedback.

Two possibilities:
1. a stray process is maxxing out your CPUs, and the fans are running normally to keep the heat down. To diagnose this (A) open /Application/Utilities/Activity Monitor, choose "All Processes" from the popup menu, then click the CPU column to sort by CPU amount. Look for anything that consistently uses over 30% CPU.
2. If you've been messing with SMC fan control, it's possible your fans are out of whack. To fix this: (A) make sure you uninstall all fan control software -- there are at least 2 different programs out there, so make sure you uninsall all of them. (B) reset your SMC chip as per: http://docs.info.apple.com/article.html?artnum=303319 (C) when you reboot, if your fans are now quiet, make sure you actually feel the macbook's case -- in one case I had, the fans stopped working which was nice & quiet, but it quickly became blazing hot which was not good.

Quiet cooling solutions on MSI's new RADEON X and GeForce 6 series VGA cards? Which is quietest?

Hi.
I am, like many people are at the moment I'd imagine, trying to find the ideal graphics solution for running Doom 3. Say what you will about it, but I've played it, and I for one want to get my hands on it in a bad way.
The problem is that my PC doubles as a crude workstation for digital recording, and my condensor mics tend to pick up even very faint sounds. My current system configuration is: P4 C 3.2GHz, ASUS P4C800-E Deluxe mobo, 1GB DDR400 in dual channel, WD 3.6GB Raptor SATA HDD for OS and apps, and two 120GB Maxtor drives in RAID 1 for audio data storage, and the weak link as I call it, my gaming-inept Matrox Millenium 64MB. (Great for work...terrible for games, as expected). All this is running in the Antec Sonata case, and boy is it ever silent. I have to turn off my supposedly silent air filtration system across the room just to hear the PSU fan lol. It's been very good to me.
Doom 3 is the only game I intend to run on this system, simply because, call me crazy, but I am an old school Doom level editing addict, and I actualy like the tight narrow repetitive cooridor style gameplay it lets me enjoy. Furthermore, using editors feels alot like tinkering with my audio software, a feeling I very much savor.
I was going to go for a HIS Excalibur X800 IceQ II because they are supposedly extremely quiet, but darned if I can find one for sale anywhere on the planet. Lol.
So, I have decided to turn to MSI, who have never let me down with respect to near-silence in the past with their VGA cooling solutions.
So my questions are:
1) The NX6800 128MB (non-ultra, non-GT variety) is very quiet from what I hear, when the fan is set to the (default) lowest setting. Does the NX6800GT or Ultra feature the same cooling solution, and is it just as quiet, nearly as quiet, or noticeably louder than the plain variety?
and
2) I have heard in general that the new RADEON cards are much quieter than the GeForce 6 series cards. Does this hold true for MSI's X800 cards as well, and is the RX800 XT as quiet or quieter than the NX6800 or NX6800GT, etc. ?
Note that I care more about silence than performance. I would be perfectly happy running Doom 3 at 1024x768 at medium or even low settings, as long as I can keep the framerate smooth. I'm not very picky.
I would be truly grateful for anyone's assistance in this matter. Thanks very much in advance.

Thanks for the reply and the info.
Yes, they do run much quieter in 2D. But are there any decible readings anywhere on the net for the stock X800 PRO cooler (in 2d or otherwise)? I ask this because, let's face it, most reviewers tend to focus on the performance rather than the decible levels (as long as the noise level is tollerable to them, they usualy give scores without going into much detail about how loud or silent something is), and being quieter than the competing products doesn't neccesarily mean it's truly quiet.
Basicaly, by quiet, I mean so quiet that it would be hard to hear it unless I get closer than two feet to the tower, and even then, rather faint or even inaudible unless I actualy put my ear up to the tower. My mics are that sensitive. Is the X800 Pro that quiet with the stock reference cooler? I'm thinking it probably isn't, but I could be wrong. The Toxic Pro of course is more than quiet enough, but I have some concerns there.
I would prefer the X800 XT or, at the very least, the plain 6800 128MB, as they both (even the 128MB normal 6800) score higher consistently in Doom 3 benchmarks than the normal X800 Pro (not overclocked). While I'd prefer a 256MB card over a 128MB one, and Sapphire using the VGA Silencer on their Toxic Pro is a nice touch, that card overclocks the memory freq, which is a no-no with Doom 3 from what I've heard. Doom 3 doesn't like overclocked cards, as John carmack said, and that seems to be true given that I've heard lots of people complaining of artifacts with even moderately overclocked cards, be it the memory or core frequency. I could, of course, just not use the "A.P.E." functionality, and run it at stock X800 Pro speed, and with the silence on the Toxic Pro it would be great...but then why not just get the higher performing 128MB 6800 for roughly the same price or less?
See my dilema? Lol.
Idealy, I'm hoping MSI's X800 XT or their GT or Ultra versions of the 6800 will have quiet cooling solutions. If they do, then it would save me alot of work making up my mind. No overclocking, guaranteed stability, total (or near total) silence, and guaranteed to handle Doom 3 (atleast fairly well... like I said, I'm not too picky), and I wouldn't feel short changed on performance either. As it stands now though, unless I can confirm whether or not they do, I'm going to have to settle for their standard (but extremely quiet) 6800 128MB.
Any further thoughts (anyone?) given the above considerations? Thanks again. I really appreciate it. Good idea on the Toxic Pro, just perhaps not ideal for my situation.

I reset the smu, cooling fan stays on continuously,

Is the cooling fan supposed to stay on all the time? I've had my IMac since late 2009 and the fan never came on until I reset the SMU yesterday, now it stays on. I looked at the activity monitor and all is quiet. Should I reset the SMU again? Thanks for your time.

Reset the SMC again.

Xserve cooling fan's not working properly?

I have a slight problem with my XServe, it's an older PowerPC G4 (Dual 1.0Ghz) with 1.5GB RAM (3x 512MB).
The fan's make a lot of noice, and I don't mean just the "normal" noice you'd hear from the fan's but more a sound as if the fan's can't run properly.
according to Server Monitor, the fan's do run at quite regular speeds.
the machine only has the options for one extra 512MB RAM module and one extra HDD, further it's "as good as it gets" for this model.
I have the additional 512MB RAM module and I intended to put it in today, I noticed the noice when I started the machine as a test to make sure everything was OK before installing the additional 512MB, but it seems, it's not OK.
I got the machine (for free! ^_^) a while ago with some spare parts (basically, two Apple Care part kits, but without the HD's) which included two cooling fan's, so I can replace them.
that is, I could, if I'd know how....
I wonder though, if there really is something wrong, or that the sound is just because the system hasn't ran for a while.
it has been standing still for a few month I think, so it could be the fan's just need to "run in" a bit.
the sound also it not very much standing out, yet it is quite easy to hear there is some sound there which shouldn't be.

I had one of these units. It was a great machine but it was LOUD. The reason behind this was that the fans basically had one speed... FAST AND LOUD.
The latter units had variable speed fans and were a little more quieter.
It bothered me so much that I rigged the unit so the fans would only run at half the speed. It was useless though as the machine got pretty hot. Maybe if it was in an a/c data center it would be different.

Cooling fan runs constantly on Tecra A3

I have a Tecra A3 an my fans runs constantly, even when idleing, and it has done this since i got it (about 18 months ago). It also runs at a constant rate, and it's just like hear Arnold talk - very annoying. Sometimes one (?) of the fans stopp running for just a couple a seconds, and then it starts again, back to the same speed. I've had the computer in for repairs, and they changed the fan and cleand the cooling system, but this didn't make things better, well, okay, I got rid of the ratteling sound, but that was all!
I've tried everything i can think of, currently I'm running the computer fixed on the lowest setting for the processor speed and battery optimized cooling by the help of the Power Saver utility, but it doesn't seem to help at all. I also tried setting the processor speed to low in the BIOS setup, this made some difference, and the fan stayed of for periods of up to 30 seconds (!), bur the performance of the computers performance was horrible with these settings so I had to change it back to dynamic processor speed.
As for the the temeratures i get at temperature of about 36-37 degrees celsius (95-97 degrees Fahrenheit) for the HD temperature (using speedfan). So theres no problems with overheating (?). This leads me to believe that this might be due to a bug in the software. I'm currently using a norwegian install of Windows XP with SP2, it's a custom install, provided by my university (my computer is a student PC bought through the university).
So, can anyone help my make my computer quiet, like normal, sane computers ?!
Thanks in advance for any help!

Hello Stigs
I use Tecra notebook (M1) for years and I can tell you that this model is really one of quietest notebooks I know but it is definitely no utterly quiet and cooling fan runs almost constantly but on slowest level. I know that it has nothing with your problem but I just want to say that quietest notebook produces noises.
Reading your posting I can just say that you are probably right when you say that it can not be because of hardware because the notebook temperature is OK and there is no sign of overheating. The fact is that all newer notebooks are louder than some old models and Tecra A3 is one of them and unfortunately there is no much to do. As far as I know nobody has reported about any software bug till now. Many bugs are fixed by BIOS updates and all I can recommend you, is to check if new BIOS version is available and see if this can help. Please before you start with BIOS update read carefully Instructions how to do this.
Good luck!

Macbook pro cooling fan runs continuously after software update

I updated Mountain Lion last night (Mar 15, 2013). I forgot the version number, but it was 10.8.? I think.
After restarting the computer this morning, the cooling fan suddenly shot up, making crazy noise. It didn't come back, so I had to turn the computer off with physical switch. While the fan was running, battery was draining so fast. I began with 100%, but went to 65% in 45 minutes. Such thing never happened before. I did not run the computer with complicated Apps when it happened. I was using Safari and Logos Bible software. Does it have anything to do with the new software?
It is quiet right now, after restarting. I paid more than $2k for this computer last fall. Didn't have any problems yet. But it happened all of a sudden. Anyone has any idea??

Next time this should happen try a SMC reset:

If no success, look at Activity Monitor to see if you have a 'runaway process' and terminate it if not required by the OS or perform a restart.

Not too cooler fan

I just bought a custom "mega" computer. I know very little. The cooling fan on the motherboard is so loud it drives me to distraction. I'm told if I upgrade to a quieter fan I will void the warrenty on the motherboard -or- Intel duo proccessor???

M30X-125 cooling fan is running very often if USB device is connected

Hello,
I have used USB devices with my M30X-125 for a few months and noticed that as soon as I connect a USB mouse or printer with external power supply the fan cooling works very often.With no USB device the fan cooling is very "quiet".
I updated the BIOS with the last 1.90 release and changed parameters (reduce processor speed) of the Power Management Utility.No effect on this fan cooling issue.
Can you help me please to limit fan cooling work with USB device connected?
Regards

Hi Phil
I agree with you but I believe that it is not easy to make a optimum there. If you check other notebooks from different producers the cooling vents are not so quiet. Like you know the units are designed to be small and a lot of hardware is placed at small place. The warmness is very high especially if the CPU activity is high and the units must be cooled before the hardware can be damaged.
I have tested cooling method intensively with my unit (Tecra M1) and if the cooling method and CPU activity is set to lower level the unit doesnt run like I want. Because of that I can live with sporadically running cooling fan but the performance is fantastic and all running processes flow smoothly.

Compaq C700 cooling fan's part number?

Hi
I wonder if the cooling fan 438528-001 can be used on Compaq C700?
It does not show Compaq C700 is compatible with it on hp.com
But when I searched on ebay, many compaq c7800 cooling fans for sale have part number 438528-001:
http://shop.ebay.com/?_from=R40&_trksid=p3907.m570.l1313&_nkw=compaq+c700+fan&_sacat=See-All-Categor...
FYI on C700's service manual, the part number is 454944-001.
Could anyone pls clarify?

Satellite A215-S4757 - Battery life and cooling fan issue

Hello everybody,
I would like to ask a few questions abou my system: first of all, the cooling fan is running in my opinion too often: almost continuously, with brakes of 2-3 seconds. Is this normal?
I have my laptop since august last year and I think it shouldn't be a problem of dust, because it is too "young" for that and I don't live in a "dusty" appartment...
Anyway, I think the "almost allways running fan" problem appeared about 2 months after I purchased the notebook. I have installed "Speedfan" and I see "HD0" temperature is increasing from about 30deg immediately after I start the laptop, to about 39deg after 1 hour.
But the curious thing is that so named "Core" temperature is oscillating from the beginning between 45deg and over 52deg! The fan starts each time the core temperature is rising over 50deg and stops when the temperature reaches 45deg. Is this behaviour normal???
Is the core temperature of 45-50deg normal? I am just using my laptop for Internet browsing, e-mails, etc., no complex 3d games!
The second thing is that the battery life is (and was from the beginning) not spectacular: it lasts max. 1,5 hours with wireless on, but normal use of laptop (not playing dvd's or something like this). Is this normal? If yes, is it because of the amd turion 64x2 processors?
Please help me with some advices / opinions.
P.S. I've bought my Toshiba as I was on trip in USA (NY).
Thank you very much in advance.
Conrad

> I would like to ask a few questions about my system: first of all, the cooling fan is running in my opinion too often: almost continuously, with brakes of 2-3 seconds. Is this normal?
Im an owner of a Satellite A210. Its similar to the A215. The A210 is a European model and the A215 belongs to the US notebook series.
I have noticed the same on my A210 and I think its normal behavior.
> But the curious thing is that so named "Core" temperature is oscillating from the beginning between 45deg and over 52deg! The fan starts each time the core temperature is rising over 50deg and stops when the temperature reaches 45deg. Is this behavior normal???
The CPU temperature of 40-60deg is nothing unusual.
The temperature could arise up to 70-80degrees while playing a game. So dont worry about the temperature.
The cooling modules are controlled by BIOS. The fan table is stored in the BIOS and it contains informations about temperature limits and the cooling usage.
If a certain temperature level was reached the cooling module starts to rotate with a certain speed.
Now I would like to say something about the notebooks battery life time
Generally the battery life time depends on the notebooks usage.
While playing games or watching movies the battery would discharge much faster.
Anyway, your notebook was equipped with high-performance devices and as far as I know the Vista was preinstalled on this series. Both factors (high performance devices CPU and GPU) + Vista OS need a lot of battery power. Vista needs more notebook resources as the Win XP and therefore notebooks with Vista OS run shorter on battery as the notebooks with preinstalled Win XP.
Last but not least you have to know that there are different battery models A stronger battery with higher *mA* value would help to run the notebook longer using the battery power.
Hope I could clarify this question.
Bye

How many cooling fans are in 13" MacBook Pro retina?

I just got a late 2013 13" MacBook Pro with retina display and I'm wondering how many cooling fans are in the machine. I've noticed when I use iTunes to play music/movies or use the iTunes visualizer, it gets hot. I've seen the videos on the retinas and I've notived that the 15" model has two and I can't find any videos or pictures indicating whether the 13" has one or two. I know that the openings on the side are to bring in air and then pushes it out where the screen and the keyboard meet. I notice a lot of hot air coming out more towards the right of the machine than the left. I had a mid 2012 non-retina Pro but I had it replaced as it had too many issues and I know when I used it, it didn't get as hot when I did this stuff. I'm just making sure in case it's an issue, even thought I got this new MacBook on Monday 6/9/14. I'm also guessing it heats up faster since its a smaller machine and the components are a lot closer. And I understand that playing games or doing something that requires a lot of processing or graphics power will cause the machine to heat up since it's requiring so much from the machine. Like I said, I want to avoid having issues with this one. My last MacBook had three logic boards, two hard drives, hard drive cable, hard drive bracket, and clam shell replaced in less than a year of purchase in September 2013. When the hard drive crashed last week for no apparent reason last week, I took it to Apple on Monday this week and they finally made the choice to replace it completely and I upgraded to a retina just by paying the difference.

This is my mac's info. I got it as a gift from australia. Initial 3 months it gave me a superb service, but recently it's having a major overheating issue,it shoots up up to 87 degrees. Is it possible that any other components are damaged somehow? Usually the temperature shoots up while I play online streamings.
