Is MacBook Air Loud?

I've got. KIRAbook (pc ultrabook). But the fan is incredibly loud. I'm considering replacing it with a MacBook Air. But I don't want to replace a loud computer with another loud computer. Thoughts? I'll be using it all day long via a Thunderbolt Display and using Windows 8 Pro. I'm an attorney and do email/word processing all day.

No, the most noise you will ever hear it make is if the fan turns on. (Which is perfectly fine.)

Macbook Air Loud Beeping!

Hi there,
I have become concerned lately, I have been finding that when I close my macbook air so that it goes on sleep, it will sound a fast and loud beep when it actually goes to sleep (not straight when the lid is closed). This is usually when it is plugged in.
However, sometimes when its not plugged in, and I may pick it up off a desk, or tilt it sideways to find the USB port, it will also make this loud beep. It's a little embarrassing in lectures!
Is there a problem with my hard drive or something? I have gone into utilities and used the disk utility to check my hard drive status, and it just says OK.
It never used to do this when I first bought this in Feb/March!
Any ideas?

Hi LeonJ,
A beep of any sort, outside of a POST chime on startup (which is more of a chime, than a beep) is not normal. There are diagnostic "beeps" built into the EFI firmware of Intel-based Apple computers used for diagnostics of component failure. Although typically the beep is on startup, not on sleep or shutdown.
Whereas Pappy's issue sounds more inline with when the beep should occur. Here are a few articles on some of the noise/LED-based diagnostics for the MacBook Air. But as iSMH previously identified, a service call might be the best solution. Even if it's a phone call into support for initial diagnosis.

Audio too loud on my MacBook Air!

So, I just purchased my MacBook Air from Best Buy (as an Open Item since there was an awesome markdown plus coupon markdown on top of that, and 18 months financing is pretty cool too). My problem is that the sound is extremely loud on this system, especially when I have headphones plugged in. I have the master volume at the 4-5 level (out of 16, mind you), and headphones can only be set on 1 (or if using the gradual shift with Shift+Option+Vol Up/Down it would be more like .5). If I have it set to full volume, the speakers are blaring (and I'm sure I'd be permanently deaf if I tried that with headphones on). This is my first Apple laptop, and I don't have this issue with my iMac (but I've got a pretty decent set of external speakers hooked up to that, so if there is an issue I don't notice it).
I tried fiddling with the sound in the System Preferences, but all I have access to is the Alert Volume slider and the Output Volume slider (which I found is the same as using the volume hot keys). And for the Output preferences tab, I can select the headphones, but all it gives me is a balance slider, no individual volume control for them.
I've been googling and searching this issue in this Support Forum, but most of what I'm finding is about the system having the opposite problem (extremely low audio), and the few that seem to have the same problem as I do aren't really getting a definitive answer. I thought I saw one where somebody had this problem and took it into an Apple store, where they popped the laptop open and noticed that something wasn't hooked up correctly (wires hooked up wrong, or something like that). But I can't find that particular thread anymore, so I'm a bit uncertain on that - anybody know where that thread is and can I have a link?
I'm wondering if this particular MacBook Air was returned because of this sound issue. Should I take my MacBook Air in to get it looked at? And if so, should I just go into a full Apple store rather than the Geek Squad (which is more PC oriented)? I did purchase a Geek Squad Black Tie plan, mostly for the accidental coverage. (I'm a klutz).

I think I might have figured out why the volume is bothering me.
On my iMac, I have a decent set of Creative external speakers hooked up and it has an external volume/bass controler w/ headphone jack. I've set up the volume on the speakers to a comfortable level, and use the iMac internal sound control to do minor editing - which is normally set around 11 out of the 16 "notches" and that way I can increase/decrease w/o fiddling with my Creative volume control.
But when I unplug those speakers out of my iMac, I end up with the insane volume that I'm not used to (I jumped when the sound played and had to mute it. XD I think I should start video logging my troubleshooting for the lulz.) I also figured out that the system remembers the sound levels when you plug/unplug headphones/external speakers. Very handy. :3
So, I'm just used to having a fine tuned control over my sound, and when I started playing on my MBAir, I thought something was wrong. I'm probably just going to go get myself a really good set of headphones that have a volume control on them so I can get the same results I get from my iMac.
Thanks for the help! <3 I'll let y'all know if I run into anymore problems!

Why is my macbook air making such a loud noise?

I have a Macbook Air 13". I have just switched it on and the fans are making are considerably louder than usual. The laptop isn't hot at all, in fact from what I can feel it's blowing out quite cool air. Any ideas on why it is doing this and how to stop it?

Hello there, Carly.
It sounds like the fans on your MacBook Air are running at full speed after you've turned on your computer. The following Knowledge Base article offers a great recommendation for troubleshooting this issue:
iMac: Fans run at full speed after computer turns on - Apple Support
If you press the iMac power button while you are connecting the power cord, the iMac will enter a mode in which the fans run at full speed. In order to correct the issue, reset the SMC. Your iMac should now start up and operate as expected.
To avoid this issue, be sure to start the computer by pressing the power button after you fully connect the power cord.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

Macbook Air Mid-2011 Loud, hot, burning, help!!

I am about to give up and sell this thing, but I'd like to see if anyone can help me first before I make my final decision.
I have a 2011 Macbook Air 11.6 inch. It has all the latest updates. I've installed windows 7 via Bootcamp.
Whether in windows or Mac, the computer will get really hot and the fan would be loud. I'm not a gamer. This is regular internet browsing, reading and shopping. I just also notice now when I put the computer to sleep in Windows, the thing is burning up. I open the notebook thinking it has had plenty of rest and even though it was asleep, the bottom of the notebook is crazy hot. The power was plugged in while it was sleeping because I wanted to charge it. Did the charging have anything to do with it? I never had issues charging my dell during sleep.
What is going on here? Should I uninstall windows 7? But like I said, this will happen on the mac side too. I'm not using parallel, I'm using boot camp which I thought was the right thing to do.
Is this normal? Should I send my unit to Apple for repair?

I think it's worse on the Windows side, and I'm not sure, but I thinking it's particularly worse when it's charging. If I'm surfing while the macbook is plugged into the power supply, it heats up faster than usual.
How do you recommend checking things on Windows side? On Macbook side, activity monitor seems normal. There is nothing above 4%. In windows task manager, all cpu says 0, but for the memory column.. firefox is using about 290,000k, flasyplayer about 23,000k.
As I'm writing you, the computer has calmed down a bit after I unplug the charging. There is something going on with the charging. Like I said in my previous post, when I put it to sleep, I came back to find it burning, probably because I was letting it charge during sleep.

MacBook air running slow and fan really loud how to fix?

MacBook Air running slow and fan is really loud and using lots of battery. How to fix?

Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity

HT1338 My macbook air got some loud noise

Just recently my macbook air got a loud noise when i plug in my cable. the fan sound is very loud and i just purchase my macbook recently,may i know what issue is that?

When you think about it, you'll have to agree that with this "description" we can't do much - other than advising you to "turn all sounds off"...
So, a better explanation of what type of noise and possibly in what situation it occured would be absolutely necessary.

Hi, my MacBook Air have gone black and its beeping loudly. What to do???

My MacBook Air has gone black and its beeping loudly. What to do?

You have to take the computer to the Apple store to have it fixed.
Best.

Macbook air getting loud

is it normal for my brand new macbook air to get really loud when I'm playing non-intensive games from the app store?

Yes that is normal.
“During processor intensive activities—such as processing HD video or playing a game that makes extensive use of the graphics processor—the fans speed up to provide additional airflow.”

My macbook air's fan is making a loud noise

i have had my macbook air for about 4 months and now the fan around the f1 f2 keys is relly loud it started today and its relly loud help

Yes, thats plate or screw pop, check the bottom for a loose screw.
If not then normal, its the alloy plate flexing under torque from grabbing it at one end and the weight causing the plate to pop just a bit

When I'm streaming videos from my Macbook Air to my AppleTV, my Macbook Air gets rather hot and the fan works hard and is loud trying to keep the laptop cool. Is this harmful to the laptop? Is this normal?

When I'm streaming videos from my Macbook Air to my AppleTV, my Macbook Air gets rather hot and the fan works hard and is loud trying to keep the laptop cool. Is this harmful to the laptop? Is this normal?

My MBA fans start running when I play video too - the CPU's video processor is working pretty hard to decode the video. The fans job is to provide better airflow. The time to worry is when you play video and the fans don't run.

Macbook Air mid 2014 air-ventilator is very loud

Hi guys,
my Macbook Air's ventilator is running very loudly when I am playing intensive-graphic games. For example when I am playing Tomb Raider. Can my Macbook Air handle it or should I leave the game out ?
Thank you for responding. I appreciate it
Jake

If it doesn't normally run loudly, then it's doing so because of the heat created when playing certain games. It's best to not play those games or, if you must, then don't play for too long in order to reduce the heat produced. The fan will run loudly in order to remove the heat. You could also try using external ventilation and be sure to place the computer on a hard surface and elevate the rear about 1" to allow better air circulation.
I would also suggest installing iStat Menus 4.21 and keeping an eye on temps and fan speed.

Attn: ALL APPLE PORTABLE OWNERS -Macbook Pro, MacBook Air Apple portable slowdown / kernel high CPU solution

Attn: ALL APPLE PORTABLE OWNERS -MacBook Pro, MacBook Air, Mac mini slowdown kernel / high CPU use problem and solution.
YOU COULD FRY YOUR COMPUTER IF YOU DO NOT FIX THIS PROBLEM SO PLEASE READ THIS ENTIRE MESSAGE!
YOUR MAC WILL THANK YOU
Hey all.
Like many of you I've got a newer Apple portable which slows down to an unusable level for an unknown reason. In my case a 13" mid 2009 Intel MacBook Pro Core 2 duo laptop. After many failed attempts to figure out what this nutty problem is I have discovered the problem, the solution and I have solved this for my own MacBook Pro. Since this fix it has been working immediately and consistently -without issue
I am sharing this with you in hopes that you to can fix your Apple portable yourself or so you know what to tell the Apple techs so they can quickly fix your Mac from this wacky and unfortunate kernel CPU hogging problem.
User Software Symptoms :
Your Apple portable computer periodically for an unknown reason slows down making everything frustratingly slow. This happens even when running previous apps that were never a problem; things that your Mac should be able to handle easily but for some reason now it can't.
Slowdown most often happens during high CPU use such as gaming, video playback/editing, etc. or when running multiple apps (even non CPU intensive apps) at the same time.
Possible Hardware Symptoms:
Your computer is making more noise than it did previously.
Your computer occasionally makes more noise but then gets quieter.
Your computer is always extremely quiet (too quiet) even during high CPU apps -worst case scenario.
It feels hotter than it normally does. Test: After several minutes of the slowness/high kernel CPU touch the computer to feel if it's hotter than normal.
Looking at Activity Monitor (in the Utilities folder) shows the kernel_task is going bonkers eating up CPU but you have no idea why.
After trying many different things to solve this problem such as :
PR ram reset, SMC reset, fresh OS install of 10.5 and 10.6 on external hard-drives, calling and speaking to various Apple tech people who had no ideas/solutions, etc. I had no luck.
Btw, if you're having the symptoms I've decscribed above I would not run the Apple Hardware check (read below as to why). You could fry your Mac!
After much testing I found the problem :
It is my belief that "recent" Apple portable computers are using low quality internal fans which soon stop working!
Fail time period seems to be about 1.0 years to 2.5 years of use but this fail rate could vary depending on use.
First noticeable symptoms (depending on what you notice) could be computer slowdown or your fan is making more noise than it normally does. This is your fan's lubrication slowly eroding making your fan spin slower and less smooth resulting in the louder noise and slower rpm spin speed. The slower fan spin speed means less cooling is happening for your computer. The effect on your computer is that the CPU and other chips are heating up! Overheating to be more specific. When your computer's chips overheat they get wonky and screw things up. Most often this seems to have the effect of making the kernel hog CPU resulting in a frustratingly slow user experience! Heat kills computer chips and it is extremely bad for them. Extreme overheat or repeated overheating has been said to shorten the life of computer chips or in extreme cases even fry them completely!
The longer this goes on without being fixed your fan loses more lubrication and spins slower and slower cooling lesser and lesser resulting in your CPU heating up more and more possibly shortening the life of your Mac! Eventually your fan will stop completely and you could fry your chips! My fan stopped completely and my MBP was running very quietly, too quietly. Luckily I did not fry my chips because I was avoiding using high CPU apps because I knew something was wrong due to the massive slow down and wonkiness when I'd run them.
Side Note:I'm a bit concerned about all those Mac mini servers which may be using the same defective low quality fans which cannot be easily serviced by their owners as they are co-located in some server facility. One positive thing is those facilities are usually well airconditioned keeping temps low.
I suggest you do not run the Apple hardware test if you suspect your computer is overheating because the hardware test can seriously heat up your Mac! I tried running this test and my Mac got so hot I had to shut it down forcefully and I was concerned I damaged the chips. If you want to run the Apple hardware check make sure your CPU temperature is ok and that your fan works well before you run the test.
IF YOU DON'T FIX THIS PROBLEM YOU COULD FRY YOUR COMPUTER DUE TO HEAT DAMAGE!
DO NOT IGNORE THIS PROBLEM YOUR MACS LIFE MAY DEPEND ON IT!
First you need to properly diagnose this problem and see if your CPU is getting to hot and you need to see if your fans are spinning at high rpms giving proper cooling, or if they are spinning at low rpms when running high intensive apps as your CPU temp increases.
TEST IF YOUR FAN(s) IS WORKING CORRECTLY :
Unfortunately Apple does not include CPU temperature reading software nor fan rpm speed software that I am aware of.
However, There are two free ways that I know of to check your CPU tempurature and your fan speed :
One app shows fan speed, and CPU heat, etc.
One app shows fan speed, CPU heat and allows you to adjust your fan speed settings.
One app is a dashboard widget, the other is a system preference.
I suggest you download both of these to check your computer statistics.
http://www.eidac.de/?p=134
http://www.islayer.com/apps/istatpro/
http://fan-control.en.softonic.com/mac
I am not exactly sure what proper CPU temperatures are for the different Apple computers and this will change given different CPU loads.
My MBP doesn't seem to function properly with anything around 90 degrees or higher (celcius).
It seems when the fan is operating normally the CPU temp should not stay above 78 degrees even under heavy load, at least with the apps I'm running in the room temperature I'm in.
I can post back later with more specific temps under longer load, etc. but I wanted to get this post up for people to read as soon as possible so they don't fry their Macs.
If a bad fan is your problem :
THERE ARE ONLY TWO SOLUTIONS FOR THIS PROBLEM :
Fix or replace your fan so it cools the CPU and other chips properly.
I fixed my fan myself and I didn't need to buy a new one. Total cost was about $8.00 because I had to buy a #00 sized screwdriver and had it shipped to me. Price includes shipping.
On my mid 2009 model MacBook Pro fixing the fan was incredibly easy :
Before I started doing this I wasn't 100% this was the problem so I decided to try to fix my fan instead of ordering a new one and replacing it. As it turns out I didn't need a new fan, I only needed to clean the existing fan and relube it's axl so it could spin easier like when it was new. It also didn't make sense to buy a brand new fan from an Apple authorized parts reseller selling me the same low quality fan for $49.00 which would probably fail in 2 years again. Prices for new comparable fans from different manufactures range from about $15.00 USD + shipping to around $49.00 USD + shipping depending on where you order them from and what brand you get.
How to fix / replace your internal fan on a mid 2009 MacBook Pro :
Please note : I am not a hardware technician, nor expert. If you decide to fix your Mac yourself you do so at your own risk through no fault of my own. Prior to opening up your Mac you should google around and learn how to do it correctly and safely so you won't damage your Mac. For example, it is possible for you to damage your Mac by static electricity from your body. To avoid this I believe proper procedure is that you wear a 'ground strap' (around your wrist) which you clip to your Mac's metal body so your body will not excude a charge into your Mac. I believe the idea here is to keep your body's charge level and your Mac's similar. Since I do not have a ground strap and fixing/replacing the fan doesn't require touching any chips I did not wear a ground strap during my fan fix. What I did was periodically repeatedly touch the metal case of my MBP hoping that would be enough and it was. Avoid unecessary actions that can build up a static charge in you. Once I started the repair I did not walk around the room building up an electrical charge in my body. Walking on carpet can often build up a large charge in us so it is better to be avoided while working on your Mac. Certain clothing can build up static charges. Combing hair, etc. If you need to get up from your repair when you come back make sure you first touch the Mac's metal case and not anything inside.
Now that we're done with the scary paranoia, below you will find some instructions on how I fixed my MBP's internal fan
Before you begin:
Check out someone's video (not mine) on how to remove / replace the fan (but not take it apart and repair it):
http://www.youtube.com/watch?v=AghE9newvbs
Check out someone's web page (not mine) on how to replace the fan in a mid 2009 MacBook Pro:
http://www.ifixit.com/Guide/Installing-MacBook-Pro-13-Inch-Unibody-Mid-2009-Fan/ 1338/1
How to repair your mid 2009 MacBook Pro fan:
Make sure you are in a 'secure' environment. No pets, no kids running around, no drinks near the Mac, etc.
Make sure your computer is unplugged from it's power supply and turned off. NOT slept. Totally off / powered down.
1. Get a size #00 phillips screwdriver (Hobby store, Radioshack, Amazon).
2. Open up your MBP by unscrewing the bottom (yes flip it over so it's resting upsidedown). Note where each screw goes because some are different lengths. I placed each one around my MBP where they go, insuring I know their order (don't jumble them up). Note which direction your MBP is facing when it's upside down so if you spin it around while working on it you still know where the screws go.
2b. Some recommend removing the MBP's battery but I didn't do this step. You probably should, just to be safe. Follow the online instructions from the web page I listed about disconnecting the battery.
3. Unscrew the fan's 3 holding screws.
4. Unplug the fan's electrical connection (lift it straight up off the board). If you need to you can try to pry it up while you lift with a non metal/non electrical conductive object like a spudger if you have one or -perhaps a pen cap. Before you remove it, look closely at how it's attached so when you put it back on you won't wonder if you're doing it correctly. There's only one way it can go because it cannot fit 'the wrong way' but looking at it closely will make you feel more confident popping it back on when the time comes.
5. Remove the fan - it easily lifts out.
6. Take the fan apart by unscrewing it's one screw then unlatching the plastic clips which hold it together.
7. Seperate the fan blades from the housing. Lift the fan blades off of the fan housing by pulling it straight out away from the housing.
8. Clean off the dust that's gathered. A can of compressed air helps here (I didn't have one). I used a little brush from my electric shaver kit which worked well. Once you've removed all the dust from the fan and surrounding areas proceed to the next step.
9. Reapply new lubrication. You need less than 1 drop. Be sure it covers the entire fan blade axl as this is what needs to be well lubricated. Make sure there isn't excess oil that will fly around when the axl/fan spins at high rpms. I used the only oil I had which was olive oil (for cooking!) but I do not suggest this. At the time I was doing this I didn't know my fan was the problem so I wasn't even sure I was going to relube it. You should probably use something more appropriate perhaps like 3 in 1 oil. A good idea would be to call the manufatures of these little fans and ask them. Maybe a hobby store knows of good lubricants for these purposes?
DO NOT use things like WD 40 as it's not a long term lubricant or so I've read.
10. Once your fan is now clean and oiled (make sure there isn't too much oil) reassmble the fan.
Push the fan blades/axl back into the housing shaft. Give it a few spins with your finger.
Screw together the fan housing then reclip the clips.
11. Place the now reassembled fan back into your Mac and screw it in place (3 screws).
12. Reattach the fan's electrical wiring by gently pushing it into place. Make sure you've got the right end facing down before you push it in place.
13. Once your Mac's internals are clean and reassembled, place the rear cover back on your Mac and screw it in place.
14. Double check you didn't forget anything like screws, tools, etc.
15. Boot up your Mac and monitor the temperature and fan speed using those programs.
Compare the previous temps/fan speed to the current temp/fan speed.
Run a high CPU intensive app where your computer has been slowing down.
You should now have a happy Mac
If you have this problem and this solution fixed it for you please post in this thread letting me and everyone else know!
Hope that helps.

Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

Mid 2013 macbook air: battery drain / running hot

Hi there,
For the last couple weeks my MBA starts to run hot and drain battery fast if I've been using it for a few hours.
I use it a lot on most days and connect to powercord only once it drops down low, like below 20%.
Have just seen other posts who recommend doing that at 50% battery and will now do the same.
However my question is: have i ruined my battery in the meantime?
AND/OR is there something else i can do to get battery running like it used to, and stop the loud fan switching on all the time because it's all running too hot?
I've copied in an etrecheck in case that helps diagnose more....
thanks heaps for any help!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
