MacBook Air :: Fan Loud At Low CPU Usage
Jun 1, 2014
I have a MacBook Air Late 2010, and the fan over heats at around 30% CPU usage, I installed AppTamer to keep it down, but it is quite annoying to keep using it. Sometimes the fan will go at 18% when one application uses about 15%, but not 100% percent when its lots of other ones. App that generaly cause the fan to overheat are, obviously, high CPU ones, like Pixelmator, Photoshop, Xcode, but some times even low CPU usage, like YouTube or Video Content on Google Chrome, Safari and Google Chrome in general. Microsoft Office 2011, Pages, Numbers & Keynote. Even apps like Preview (viewing more than 5 photos ) can use alot of CPU. So what should I do? I have repairs under warranty till about September, but Apple charge £35.00 to chat online?!?! I have tried resetting the SMC which only works about half of the time. I read on the internet that it is a production issue or at least common Late 2010 MacBook Air's.

I just bought my MacBook Pro last week. When I power it up, it makes a loud noise for about a second and a half. I think it's the hard drive starting up or the disc drive. I'm not sure which one, but it's pretty loud, so I was just wondering if anyone else noticed this and if it is normal.

I have a macbook 13". About 1.5 years old and the fan gets really loud sometimes. I know because it gets hot but it never used to be this loud. It's like I am listening to a helicopter fly by. My brother's Acer he bought for $300 is not as loud as my mac. (Not saying that it is a worse computer)

Lately I've been noticing that my MBA rev A sounds like a helicopter taking off! Temp is around 59 and all I'm doing is surfing. Fans would rev up to 6000rpm!

I bought the macbook in mid Jan 2012. At first, the fans weren't that loud. But now with only Chrome (no videos), Word, and iTunes open, the rpm isn't that high, but the fans are too loud. Why is it that the fans are running loud, but the rpm isn't that high? Is it time to clean the fans (with only 3 months after buying it)?

I have an iStat Menubar and it's constantly showing me 40% CPU usage. It also shows the same number in Activity Monitor. However, when I look at the processes running, they don't add up to 40. In fact, they only amount to around 6% or so. I did click "All Processes", but nothing was running that would cause it to be 40%.

I own a aluminum unibody Macbook (a1278), and my CPU runs hot basically anytime I run Flash in a browser. Chrome, Safari and Firefox all spike the CPU usage to upwards of 75 to 100% when even viewing a simple YouTube or Hulu clip, though sometimes, such as now, it runs hot when Flash isn't running.
Since I've noticed this, my fan has been progressively getting worse. You can hear the ball-bearings making noise and rattling when the fan gets up to and above 3000rpm's. When the fan is at it's normal speed of around 2000 rpm's, you can still hear the rattling, though it's not making the jet engine sound it does when running faster.I have since ordered a new fan for replacement, which I will be doing myself. My questions are...
1. Will replacing the fan myself void my warranty?
2. Why oh why does a YouTube clip spike my CPU temps so high? Are there settings or tweaks I could be making to avoid this?
3. Am I an idiot and overlooking some other fatal flaw in my system?

I have a MBA:
Model Name: MacBook Air
Model Identifier: MacBookAir2,1
Processor Name: Intel Core 2 Duo
Processor Speed: 1.86 GHz
Recently I have noticed that the fan is now running far more than it ever used to. I only have to call up a couple of web pages and off it goes. The fan almost never used to come on, unless I have really using the processor, so wondering what the likely problem is.

I upgraded my wife's 13" late 11 mbp with a segate 750gb drive... Same one I put in my identical hardware on snow leopard. After using lion recover to restore the whole disk (again, same process on mine) it sits at the boot logo for a long time and the fan kicks on to high.

I've been trying and trying to get my 2007 Macbook C2D to run cooler. It idles at about 60-65 C even with no CPU usage (verified through Activity Monitor etc) and it used to get up to 95+ when playing any sort of video (Youtube etc) which would cause playback stuttering and other problems after 15-20 minutes.
I've tried a number of techniques to drop the temperature, most recently undervolting with Coolbook. Interesting, these have been relatively successful at lowering the *peak* temperature-- videos now only bump the CPU temp up to 70 C or so-- but it still idles at the exact same temperature it did before, around 60.
Does anyone have any theories why the idle temperature would remain high even after I've reduced the peak temperature, and even when CPU usage is hovering between 2 and 5 percent?

I am new to mac, and I have a macbook pro 15" 2009 model.
I am currently running a program (Mprime) that uses all the spare cpu on the mac. So that I am always running on 100%.
Do this extensive usage of CPU shorten the lifespan/quailty of the Mac/Fan/Battery?

when doing high processor use tasks like copying 5 gb files or playing hl2 on steam the processor use always stays below 50% (istatpro)
1) why is this the case ?
2) if i could use more processor time would it improve performance of high use tasks?
3) if this is not normal behavior what could cause this ?

I have a two week old MBP and I find that my battery performance is dismal.I'm only getting 2 hours per charge, and this is after Apple replaced my battery two days ago!I think it might be related to my CPU usage..Looking at Activity Monitor, my "% User" CPU usage is routinely above 26%, with only Safari running (no videos). Even with no programs open I run over 25%.

My MacbookPro is running way too hard and makes me think it's going to die any second,I just purchased it new from the apple store back in September the CPU my Java takes up is amazing. I've seen the number jump to 102+ which makes me wonder why my computer freaks out when I use java. I've included a picture of the CPU usage.                                                                                                                                              Â

For the new MacBook Air owners: how loud is the click on your trackpad?
I have a black MacBook which has the separate button (pre-glass trackpad). It's almost completely silent. On almost every unibody MacBook Pro though, the click is really loud and can sometimes even be heard in the next room.
How is this with the new Airs? Still loud or not really noticeable? I like to click instead of tap, but not if everyone can hear my neurotic clicking all day long

I updated software yesterday or two days ago. Ever since then my mac has been so loud. I turned it off a few times and restarted it, but it is the same. I guess its the fan that is making this noise, but really annoying me. version 10.6.8 now.

About 5 mins ago i rebooted my Mac, and in the boot process something started to buzz horibly. I was in a dark room, so it was very scary for me and very late too... Being scared i pushed CTRL+OPTION+SHIFT+POWER so it shut down imeaditly.
I powered it on, no buzzing. But OS X did not boot at all. Just stood there. Now I'm booting of the recovery DVDto disable my EFI pass, so i can boot verbose.

I've had my Macbook Since early 2008. But only in the last 8 Months my fan has become increasingly Noisy and Hot. I upgraded to Snow Leopard last year (I'm on Mac OS X 10.6.8 ) and it seems it became alot noisier after this. I originally only had 2gb Ram, but upgraded this week to 4gb ram thinking that would help. I've also gone and purchased an external hard drive and moved all my movies, photos, music etc onto this in an attempt to not only back up my files but hopefully alleviate some of my space on the mac. I've tried the Resetting SMC and also followed another apple step by step guide (??) and in my activitiy monitor nothing is even over 10% and i've been regularly checking for the last hour. I'm aware the fan is always running, but the noise is ridiculous. I've done so much research on this and i'm at a complete loss, I know there is only one fan in this version of macbook and it's definitely running as I hear it all the time.

I'm debating between an air and a mbpro. I'll mostly use this for internet, excel, and iphoto. Is 4gb going to be enough for these uses? I have an iMac with 8gb and it really screams. How much better is the screen on the mba? I played with both at the apple store and I didn't really notice a difference? I do like the air since it was just updated. I figure if the mbpro's came out with something really cool i could sell and wouldn't be out that much money.
