Annoying fan noise

I like everything about the new macbook air but except the fan noise. It is annoying that i am considering return it.
Watching Hulu(Flash based) is actually okay, acceptable fan noise.
Using Netflix is still okay, acceptable.
But when i use the Dishnetwork Sling player plugin to watch streaming video, and fan noise is so audiable that become annoying.
Looking at Acitivity Monitory, the system is about "60-65%" idle, while the plugin process CPU is 120-140%.
A 60-65% idle system can case the fan to be that loud, i couldn't imagine what will come next.
is Dish Sling plugin to blame? how many other software in future use in macbook air(not optipized for Lion i guess?? ) will have such fan issue?
return it and get a macbook pro instead?

Probably at least partially.
My fan, and I think everyone's fan, is running at a high rate of speed for certain high-intensity processes, especially concerning video rendering. The Air is an excellent machine with enough "horsepower" to do a great many things that heretofore were only reasonably possible on a MBP. There are tradeoffs though. one of them being a smaller fan,in a smaller package, is going to run with a little more intensity for the same task.
For me, the fan is a minor annoyance, offset by the advantages of the Air. But that's just me.
However, as Lion matures, and so do the developers abilities to turn out drivers and plug-ins that use resources more efficiently, we'll surely see some of these issues move in a positive direction.

X1 annoying fan noise even in standby.

Yesterday I switched out my Cisco RNG200 black HD DVR for the new X1 DVR.   Receiver Native Ver 2.0.2
XRE Protocol Ver 2.8.0
Environment p6-k6 This X1 unit is the one with the blue LED power, which from my google searching tells me its the latest ?  Unfortuntely, there's a very annoying fan noise that has no way of turning itself off, unless i pull the power from the unit. Even in standby mode...  I only watch TV for a small percentage of my time spent in my living room, so to have to put up with a constant fan noise even when no TV is being watched is simply unacceptable. It's coming in at 50db using SPL Meter on my iPhone next to it. and about 45db from my seating position.  Is this an inherrent design flaw of the unit, and will i be wasting my time and effort, switching the box out for something that will be equally as loud ?  I understand that this has an atom cpu and some form of cooling is req'd, but even while on standby?  At this point, i will have to go back to my local store and ask if i can either have my old RNG 200 back or move to a different provider, that has better designed hardware.  Unless I am just unlucky and that yes the fans do normally only spin up when req'd, and that i have a faulty box. Please advise.

Not as easy as just swapping unfortunately.  I've now been to two stores... Spent Fri, and Sat morning on this now. Even though they even had an Arris XG1-A as their display model, they tried to deny Arris made X1 boxes. That was at least until i showed them the underside of their own box, with the Arris sticker, and used my SPL meter app on my phone at the difference of noise coming from this box and the other Pace they had on show.. Regardless of which, they said, they didn't have any. But the lady was pretty good, she said, they could request a shipment of an X1 box, and only put it in the notes to make it an Arris box... I guess i have a one in four chance...  I also took an Xi3 box, and that's proven to be a pain also... not in noise, but in activation. After an exchange at one of the local stores and it doing the same thing, and a lenghty call to customer service, i'm having a tech come out to look into the issue. Kudos to Comcast for having escalated this to one of their X1 tier 3 support teams, who was savvy enough to realize that there's nothing wrong with my signal, and that i probably need a Point of Entry Filter installed at my box outside... Anyway, this whole X1 transition hasn't been much fun all in all. I still have a noisy box, that i'm not going to be able to put up with.. Came downstairs this morning, and it was the first thing i heard... Hopefully the one that's being shipped will resolve... I now know that the box can be hidden away somewhere completely different and have the remote control still work, but that isn't as simple as it may seem.. I'd still need to get an HDMI signal from the box to the TV, and it would involve cutting into my walls to run cat6 to accomplish that.  I may just opt for the old 80's style clunky i-guide, instead of the x1... if my third attempt of getting an Arris box fails... That or go to Dish, as the XOD has so many drawbacks on the older iGuide system.

Brand new macbook pro has annoying fan noises all the time

I just picked up my macbook pro 13'' with retina display from apple store today, and the first time when I start it, it generates constant annoying noise! no applications run, nothing, from the moment I push the power button, it just give the noises... very disappointed at macbook pro.... Restart it, same, still gives out constant fan noises.... Even the $300, $400 cheap laptops don't have such problem....

Welcome to Apple Support Communities
Your Mac may be indexing files from the flash storage, and this may cause that your CPU usage is high. In this case, I recommend you to carry on using your Mac and fans will stop working at maximum speed soon.
Another thing you can try is to reset the SMC > http://support.apple.com/kb/HT3964 The SMC is the part that manages fans speed, and if it is not working correctly, fans may not be working properly.
If the SMC reset does not work and fans carry on working at maximum speed for a long time, return your Mac and get another one.

Annoying Fan Noise - HP can u Help ???

I have HP Dv2700 laptop with Windows 7, and it's making continuous fan noise.
Is there any one in HP that can solve this issue ?
Also searched for new BIOS that can update, but didn't find one for windows 7 (currently running : Phoenix F.2D)
Do I need to Clean the FAN ?? Post video or instructions if need to bisect my laptop ?

Hey Yes1984,
Here is your Fan Doc,
Reducing Fan Noise Notebooks (Windows 7)
It will help you with cleaning "how to". Whether you open iup the case depends on if you have a warranty - crack the case and lose the warranty... The fans do run on these things. Once the unit is clean, you can run some heat checks, make sure you keep it elevated, never treat it like a "laptop" (it is NOT a laptop), maybe stick a cooler under it...

IMac 20" Fan Noise

I am very fussy about computer noise.
I have returned a 17" iMac G5 once due to the annoying buzzing of the fans (specifically the hard drive fan) that sounded nothing short of an RC model airplane buzzing around.
So I thought I would hear the same with the Intel Duo Core, but would just deal with it this time.
WOW! What a surprise!
This computer is so quiet I could not believe it. When the fans do ramp up, they are a dull ambient sound which is fine with me. I just did not want the high pitched RC-sounding annoying fan noise from the previous G5 models.
I drove the CPU to 100% on both processors for over an hour (multiple times) and the fans are significantly easier on the ears than the G5.
So if you are hesitating on your purchase because of possible noise issues, I would say buy the new iMac.
You will be impressed.

I can be very critical and nit-picky about the computers I buy.
But I must say that Apple has left me speechless on this one!
No problems at all. I added another 512 meg ($100) from the local Apple Store to give me 1 gig RAM total. Naturally, everything is that much faster as well.
Mind you, though, that I have the 20" iMac Intel Duo Core with 128 megs Video RAM (not the seemingly problematic 256 meg).
Front Row works great with no problems.

HT3964 How do I stop my Macbook from overheating and making a fan noise?

My Macbook Pro 17 Inch keeps overheating and making a fan noise after I use it for... say... an hour.
I use Windows on my Macbook, is this related to my problem? If not, do I need to get my fan replaced?
It gets annoying whenever I play a game, and then suddenly my Mac goes to sleep for no reason (probably due to overheating).
The fan noise is kept to a minimal when I use a web browser, or listen to music, but it goes up when I start an application.

Since overheating is something the computer tries to prevent, it will shut down if the temps get too hot, thus your experience is not overheating.
You can have a look at Activity Monitor (Menu Bar > View > Show All Processes) and then sort by CPU to see what the culprit is during downloading.
A hot Mac is not that big of a problem, the fan takes care of the heat and if you do not mind the noise, then that is it.

Macbook pro- OSX lion 10.7.2 fan noise

I just bought a macbook pro laptop, upgraded it to the Lion version, it is now 10.7.2, with processor of 2.7 GHz intel core i7, memory of 8GB, 1333 MHz DDR3. Whenever I am on a program like imovie, safari, iphoto, charging my smartpen...etc.... the fans goes off like crazy. It lasts for a very long time. Sometimes the noise get so bad, it goes from loud to louder...... I don't know what the problem is.
I am a new mac user, I have no idea how to install, delete, clean softwares. Please help?? Thank You ...

Thanks a lot for replying, but what exactly does the istat widget program do?
Also, the fan noise seems like a normal noise every time I launch a program, but it's getting to the point where I am frustrated(annoyed) of the fan noise. I would've thought that upgrading to a Mac book would cause less fan noise because of it's high processor. Sometimes I feel like I should go back to a Dell or HP because of this problem, but at the same time, I love my laptop. ;)

IMac g5 fan noise with update to 10.4.11

Has anyone else experienced this?
I have never had any problems with fan noise with my iMac, though I know it's a problem, till the recent update to 10.4.11. After restarting, it sounded like an airplane. Never heard that before. I shut it down and restarted, and it doesn't sound like a plane anymore, but the fan is noticeably noisier than ever before, a constant whine/hum.
Besides the energy saver fix and resetting the SMU and canned gas in the vents, any other suggestions? This is annoying, it's been running pretty perfect for three years till this. Thanks.

The questions are certainly not dumb - almost anywhere is cheaper than Apple for RAM, I recommend [macsales.com] and [smalldog.com] or [newegg.com]. I don't think that going back to 10.4.10 will help, you should really vacuum the vents to get dust out, and make sure that there's nothing hogging your CPU and making the fans noisy, look at Applications>Utilities>Activity Monitor to see if anything is using an unusual amount of memory or CPU.
If you do want to install Leopard, I would suggest making a full backup of your system,I use SuperDuper! to clone my system to a firewire external drive. You should certainly upgrade your RAM if you install Leo, but I don't think your machine will be any quieter with a new OS.
You need to remember that your machine is several years old, and that things get creaky with age (I certainly have). Since you have the iSight, it's not a simple matter to open it and clean the fans off. If you are really disturbed by the noise, you can take it in to an Apple service place and have them clean and oil the fans, which should help enormously.
Sorry I couldn't offer more help, but fans will, and do, get noisy.

Macbook pro retina start to make loud fan noise and work slow

I bought macbook pro retina display less than one years ago. For some reason my macbook pro has been making loud fan noise for about five mounth. Whenever macbook pro makes the noise, all the programs start to run slow. Typing, opening safari, and etc takes forever. It takes 20min to 40min for the noise to stop. At first, the macbook pro made noise once or twice in a day, but now it's making the noise frequently; It happens every 2-3 hours. It got to the point where it start to annoying me. Is there a way for me to fix this issue? If not, can I use one year warrenty to fix this problem? Thank you.

If your Mac works slowly when fans turn on, it's quite possible that there's a process which is eating the CPU and/or RAM.
Open Activity Monitor (in /Applications/Utilities), select "All Processes" above "Show" (in the toolbar) and then, order the processes by CPU usage. Do you see any process which is consuming more CPU or RAM? If so, tell us the name.
Additionally, you can reset the SMC > http://support.apple.com/kb/HT3964

Macbook Pro Retina 13" continuous idle fan noise

Hello,
My MBP has recently started emitting a constant noise as if the fan is rubbing. Have a listen to the noise here: https://soundcloud.com/adam-wilkie/fan-noise-2/s-VnBbe
It sounds mechanical and is constant from startup to shutdown and is really really annoying. I can hear it most of the time and it is especially audible in a quite room.
I have taken it too the Genius bar twice and they have run their diagnostic tests (which said everything was ok) and have cleaned it out but the noise continues.
Has anyone else had this issue?
If anyone could offer me some advice that would be great!
Thanks

Sigh, I guess I'll need to go to the store tomorrow to exchange it.
*****, because I don't have the keyboard/trackpad freezing issue and was able to install Windows 8.1 from USB using Boot Camp Assistant without any issues. Thought I got lucky until I found out about this issue.

DM3 (New 2010 model) - FAN NOISE - Constantly Running LOUD

This is the first HP to use "Cool Sense" technology. Yes, it is cool but at the expense of FAN NOISE. The fan runs constantly even when Thermal Assistant is set to "Quietest." Just an open browser window at 0-10% cpu makes the fan run all the time! PLEASE READ my Notes below.
After monitoring the temps, the fan still needlessly runs on medium speed even after the temperatures drop (CoreTemp gives [core#0 28C & core#1 37C] at idle powersaver). Anyone can comment on the 9C difference?
I believe hp still need to tweak the "Thermal Assistant" fan controller or raise the temperature thresholds. PLEASE HELP - VERY ANNOYING PROBLEM
Note: Latest F.08 bios & Turned OFF "Fan Always On." Computer is NEW (no dust). Used on Tabletop. Used both powersaver mode & balanced.

Try doing a SMC AND PRAM reset by:
1. Turn off your iMac and unplug everything from it for 30 seconds.
2. Plug in the power cord, keyboard and mouse only.
3. Press the power button and immediately hold down the Option, Command, P & R keys until you hear the second gong then release the keys. Your machine will start up normally, then check for the issues you are having.

Questions re Fan Noise

I have a MacBook Air Rev A. The fans randomly will spin up to 6200 when I am just doing some casual surfing in Safari or Firefox and then spin back down to somewhere around 2500 to 4000. This happens throughout a session - several times over many hours. The fans seem to spin down faster now that I have installed the latest SMC update.
The fan noise is really annoying but I put up with it since I love the weight and portability of the air. My question is this: is there anything inherently bad about the way the fan is running here? Can the system get damaged if the fans run at 6200 for awhile? I would think that's just why they're there but it would be great to hear about others' experiences. I am too chicken to install Coolbook. Thx.

I have a 1.6Ghz rev A MBA and the only time my fan revs up while surfing, is when I'm watching embedded videos. Check your Activity Monitor when the fan is revving and see how much CPU power you are using, and what apps/processes are causing it.

Updated to Mavericks and loud fan noise

Just done a clean install of Mac OS X Mavericks, updated fine, everything went well.
however most of the time, my macbook pro fan noise would go really loud for 5-10mins even in idle or if im on the internet just browsing.
this has not happened ever on mountain lion.
its really weird.
Does anybody know how to fix this? or is this a bug and would i have to wait for a software update?

Hello all,
I am having the same issue, constant loud fan noise in my Mac book pro. Below are the specs:
"MacBook Pro
13-inch, Mid 2010
Processor 2,4 GHz Intel Core 2 Duo
Memory 4 GB 1067 MHz DDR3
Graphics NVIDIA GeForce 320M 256 MB
Software OS X 10.9 (13A603)"
And CPU is 90% idle.
I tried to reset the SMC using the steps:
1. Shut down the computer.
2. Plug your Mac in, if not already plugged in.
3. Press (left side) Shift-Control-Option & the power button at the same time.
4. Release all the keys and the power button at the same time.
5. Press the power button to turn on the computer.
Inaddition, i have reinstalled OS and reset PRAM memory but the problem still exists.
It really feels annoying with the fan sound. Could someone give a fix.

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.

Annoying Humming Noise

I have a 2008 Mac Pro that has been making an annoying humming noise for a long time now. It didn't make this noise when I bought it and was whisper quiet for most of the first year. I have had all the fans and the power supply replaced under Apple Care, but it is still making the noise. It is a low, oooooWAAAAAAA, oooooWAAAAAA, ooooWAAAA sound that goes on at a steady rhythm all day. The noise did change somewhat in quality after the PSU was replaced, but no change with the fans. I have tried SMC fan control to change fan speed but that hasn't help other than to drown the noise out with fan noise. In a quiet room it is really annoying, but I am afraid if I took it in at this point they wouldn't hear the sound, as the tech guy couldn't hear it when he came out (it is more noticeable sitting at the level of the computer than standing above it). It can also be intermittent with it being barely audible at times to it being fairly obvious.
It gets louder based on the number of hard drives I put in the unit: less drives equal less noise, and the noise can get louder when I'm burning a DVD, though this is not the noise from the graphics card fan firing up, but a different noise that can be heard in background. It seems to be coming from the power supply or power supply fan.
Any advice would be appreciated.

Thanks to everyone who responded. For anyone else who might have this problem, I found what may be a solution. I read somewhere else that this noise is caused by the drive sleds vibrating against the metal on top of the drive bays. I am sorry I can't find the page, but what this guy advised is to remove the sleds from the drives and bend them slightly downward over the side of your desk so that when you insert them back in, there should be about a millimeter of black space between the back of the sled and the metal above where they slide in. Just a tiny bend seems to suffice.I did this to all 4 drive sleds and the noise has been reduced by over 90 percent. As Kappy advised here if your sleds don't have rubber grommets around the screws that would very likely make this problem worse as well.
Hope this helps.
