MacBook :: Macbook Fan Noise Is Too Much - How To Reduce It?
Dec 31, 2010
My white Santa Rosa 2.2ghz late 2007 macbook over the last few months has been getting worse and worse with its fan noise.
Currently, I have have this tab and another on the BBC News homepage (flash blocked) open in firefox writing this up, and according to istat my fans are running at around the 6100rpm mark with my CPU temp around 65 c.
Have tried and SMC reset, and hasnt fixed it. Not really sure what else to do? Checked the activity monitor and nothing else seems to be using more than 7-10% of CPU.

I just got my 2.0ghz Alu Macbook a few days ago and everything works perfectly well, the thing is that after day one the magsafe started to emit a low pitched electrical whistling noise. It tends to be there a few minutes after booting into the OS and then it turns down to almost unhearable, but I experienced it returning after a few hours of use and then disappearing again. If I move close to the escape key I can hear a crackling noise emitting from the magsafe.I'm not trying to be overly nitpicky or anything but I read somewhere that if it's doing that it would be a faulty Mag-Safe board or something.
Does any one you guys know anything about this? I have the 14 days to return it as I bought it online from the Apple Store so if it's a faulty part that might die/break/ cause problems later I might have to.

Sometimes I lift and carefully move my 17-inch MBP a short distance to another flat surface without putting it to sleep mode, it starts making really loud mechanical noise when I put it down, so loud that people in the same room can hear the noise and I can feel vibrations too! What causes this? Where does this noise come from? Is my MBP defective?

My first generation unibody Macbook hasn't had any problems to this date but now it's constantly making that mechanical loading-like noise which is usually heard when the Macbook is switched on (the noise before the start up sound) or when the lid is opened to wake up the computer. Is there a fix to this?

On my 13" MacBook Pro, the hinge makes a cracking noise on the right side of the computer (near the power button) when the screen is positioned all the way back.The entire hinge also makes a loud popping noise when I adjust the screen position. The screen seems very tight, and it takes a little bit of effort to move the screen, and when the screen is moved it makes the loud popping noise.
This is probably going to make some of you guys cringe, but sometimes putting pressure down on the top of the case close to where the black hinge meets to unibody enclosure seems to stop the popping noises. Putting downwards pressure on the hinge, or flipping the computer over and putting pressure on it that way, also seems to alter how much popping noise there is.
If I mess around a bit with applying pressure on different parts of the computer around the hinge, I can usually eliminate the noise. But, the cracking noise when I put the screen all the way back is still there.Any ideas what to do? It's not interfering with the operation of the computer, it's just incredibly annoying and this is only a four month old machine which shouldn't be creaking and cracking already.

Has anyone else had problems with an old G3 Pismo making an annoying squealing noise when plugged into a charger? There's a lot of noises mentioned in mac/apple forums but none of them relate to this one. Here's what it is not:
It's not coming from the screen or the fan or the speakers (it's under the keyboard). It's not low or slightly annoying (it is a loud squeal). It happens only when the power adaptor is plugged into the laptop.(it used to cease after I unplugged the power adaptor and plugged it back in three times; now that solution doesn't stop the noise anymore). It charges ok, and runs ok, scream or no-scream. It's quiet right now, but if I move the adaptor to another plug it will start again.
I was going to live with this, but today after an hour of operating quietly it just started again, and I hate to leave the house with this going.(it will scream whether the laptop is on or off. I have a really old battery and cannot replace it (I am currently staying in Mexico for the summer). Battery life is 45 min. I haven't tried pulling the battery out. That would be too easy.
This all started when I bought a replacement power adaptor (generic),after the original one melted down, but I could stop the screaming by unplugging/plugging it in again once or twice. Then I bought an expensive iGo adaptor, and it does the same thing.
I Did the PRAM and PMU reset.I can hear it over music or the tv. It grew lower in pitch today after squealing for a half hour. I'd normally not let it go on that long, but i was
in the other room.Is my PISMO dying?

I just got my macbook pro yesterday and ran it all yesterday not hearing anything. Today when I woke it from sleep I could clearly hear the fan or hard drive going. I was in a quiet room and it's quite annoying.
istat says its at 2000 rpm so thats when I started thinking it may be the hard disk. It does pulse every now and then but thats even while it's just sitting idle.
I guess I could live with it but its just annoying. Anyone else having this?

I went to Apple store yesterday. I want a new MBA badly. Only problem is the memory of current model is 2G only not expandable. The guy in the shop has no idea when new MBA will be released.
I was looking at new 13" or 15" Macbook Pro, I like it, and wonder since I don't use DVD that much, is it possible to take the drive out and reduce weight a lot?

I have an Mid-2009 13 Inch Macbook pro. I decided to upgrade my memory to 4 gigs using thirdparty memory. However, I have noticed that the amount of Wired memory usage has gone up a quite bit. My Wired memory usuage usually goes as much as 900 mbs and this is outrageous because I don't particularly open any major applications. My Kernel Task right now sits at 397 MBs, which is huge as well.
I find that with one firefox or chrome browser open, I can easily use over 90% of my 4 gig ram and that's when watching you tube becomes very difficult 9freezes a lot.I understand that I never had this problem with Windows, or even when I run bootcamp.
Here is a print out of my processes:
Active Memory: 1.91 GB
Free Memory: 1.02 GB
Wired Memory: 853.4 MB
Used Memory: 2.98 GB
[code]....

MacBook Pro, Mac OS X (10.7.3), Mid 2009 13 inch

i was playing with my MacBook Pro earlier today and used some kind of finger swipe that made everything on my screen including the homepage zoomed in and off center. I have to scroll from side to side and up and down to see the whole screen and he or I can't figure out how to change it back.

I scanned some documents with my printer/scanner and don't want to have to rescan every time. I made them too big, they are 20+ megs, and I know with JPEGs one can just "flatten" the file. Can that be done with scanned docs too? If so, how? Do I need a special app for that? I have Preview and iPhoto, plus the MS Office package for the Mac.

I'm using iStat and it says that my CPU runs at temps around high 70s, low 80 degrees Celsius for about 10-15 minutes at a time (also says the same for Airport card). It usually takes a while for it to cool down. I always place my laptop on flat surfaces. It does this even during light internet surfing minus flash or any other multimedia...now WITH multimedia use, it reaches the 80s no problem and I just quit the process cuz I don't want my laptop to explode one day.
I just wanted to know if this was average and what temps everyone else is usually running at?
I'm afraid that if it runs at these high of temps for a long time each time like that, then it may do some damage somewhere...

I'm sorry if this is a dumb question. (I feel like I know a decent amount about my MBP and about a/v matters, so, I feel a bit dumb for not knowing the answer to this.)
I have an external monitor (Samsung 2223w) monitor connected to my MBP via DVI. The MBP is shut.
Is there a way that I can reduce the brightness of the external monitor quickly with software? Of course, I can manually reduce brightness by clicking the buttons on the side of the monitor and navigating through the menus. But is there a way that I can set a keystroke to do the same?

I'm using an early 2008 MBP (4,1) running the original 5400rpm 200gb HDD but upgrading to 500gb this week.
I'm looking at WD Scorpio 5400rpm but wondering if 7200rpm reduces the battery life relevantly.
Also, I'm running 2gb of memory but I'm debating if 4gb would be dramatically faster.
Or do you think I would be better off buying a new mbp?

I just replaced my damage HD (original HD) to my MBP 2009 unibody. So far, I like the SSD drive, and I use it for my internal storage. I've been read a fews article online, but it seems I don't find the answer. My concern is, How do I reduce TBW on SSD? if I play video (like youtube, Netflix, or Hulu) or play online games, would it be increase my TBW? So far, I set up my download file to my external HD. Whenever I download file, application, or etc, it would go to my external HD. Second question, What can I do to lower the use of SSD? Therefore, my SSD will last long like 3-5 years perhaps. Third question, since Samsung Magician Software can't run on MBP. How do I check my TBW and the health of my SSD?
