Noisy Left side Fan

I'm one of the guys that can live with the "lines", but today I started with a noise like if the left side fan is touching something (trrrrrrrrrrrrrrrrrr....) on my PB HD 1.67 . What's going on?? I really cant live with this!!
It started while gaming but now the noisy fan goes on as soon as I power the Book...GRRRR
I'm I alone??
Thanks
15" PB 1.67 HD Mac OS X (10.4.3) 1gb apple ram

It is a bit more noisyer than 1.5ghz models but heck it works very nice.
Usually when I play games obviously I have the speakers plugged in and or headset+mic on so the sound is not that anoying to me.
if it is loud enough to bother you even when the game / music is on then maybe you might want to get it fixed at Apple care / Apple genius bar.
Compared to my desktop linux/PC it is so quiet.
What might help is to get one of the laptop cooling pads that has it's own fans or just raise the Pbook a little so air can curcilate to passivly cool it down.
This will reduce the fan noise or fan usage.
Also set the power option to normal as you loose about 6 fps at max display settings of the game.
Also paly your games at lower display settings maybe 800x600 32bit with normal or med-high settings as this reduces the stress/load on the CPU / GPU and so reduces heat.
This will also make it more playable and faster.

Left Side Fan 0?

Hello everyone,
I know theres a million topics about macbook Pro heat already but I have not found one about this yet. My computer is running very hot (which I guess is normal) but the right side fan is running at 6000 rpm on average and the left fan is running at 0 rpm. Is this normal or do I have a problem?
Thanks.

Sounds like a problem.
Try running the hardware test from your install DVD. If you have a problem it should pick it up there.
If under warranty, call Apple. Otherwise take a look at www.ifixit.com for instructions on how to open up the machine and replace.
If out of warranty but you bought the machine with a credit card, your card issuer may have extended your warranty for free - check with them.
Good luck.

Noisy left fan on brand new MacBook Pro 15" (started after 4 days)

The left fan (just under the speaker) is making noise, sounds as if it's catching on the casing or something.
Problem is, the Macbook is non-standard (hig-res matte display) and I need it painfully much for the next two monts - it was bought specifically for the purpose of major jobs.
Is it possible to have it fixed in a day or two or does it require ages and ages?
Thanks!

My MBP (Mid 2009) just started doing this on the left side, and I've had it apart several times trying to clean and re-lubricate that fan. The sound is not as bad now, but the increased fan noise is still present and I'll be shelling out $50 for a new one probably tomorrow. I'm putting up a YouTube video so you can hear the awful noise it was making last night (harbinger75 movies there).
Mine's not under warranty anymore, and I've been a Mac/PC tech for years, so it takes all of fifteen minutes to change one out.
Hopefully, they'll just replace the fan for you.

Left Hand Fan

So, as you can see I have a 1.83 ghz model with 512mb ram, and the 80 gig drive. The base model, no mods. I have installed Boot Camp and XP.
As of now, and since right after installation of XP, the left hand fan has run constantly. It's pretty quiet, but in a quiet room, it's annoying. I know it's not running full bore, but still, I am absolutely positive it didn't do this when I got it out of the box. It also didn't have the processor whine before, and it does now (albeit the whine is very quiet and the Mirrow Widget fix works fine).
Do you all think that the firmware update made the fan run constantly? I have a sneaking suspicion it did. Apple tech support said the exhaust fan is supposed to run all the time, but come on. I know they're totally BSing me, and that at least some people don't have a noisy fan. Tell me: Is your exhaust (left hand) fan audible? Is it on all the time?

It's likely the firmware update, and not related to bootcamp. I doubt installing another OS is going to affect fan management, but a firmware update could certainly do it. Behavioral changes are what you should expect after a firmware update, otherwise it's a waste of a download.
In all seriousness, I'd err more on the side of fans NOT coming on, then them kicking in sooner, so I doubt you have much to worry about (other than fan noise).

I am having MacBook Pro 3 yrs old and today while I was watching some movie on it suddenly it got power off and when I am trying to start it, it's power button is not working even the round button on external left side is not showing battery lights. But when I connect it to chrger then Charger only gives green light and even the external round button only shown 4 green lights (if charger connected). I don't know what to do now

Sounds like you need a #1SMC Reset
1. SMC reset
>>Instructions to reset SMC
Disconnect other non-Apple and external hardware except (if applicable) a mouse and keyboard until your finished repairing your machine.
Problems solved: Fans blowing with no activity, machine is not booting, power button pressed and nothing happens, problems with indicators, Magsafe has wrong lights, battery is not charging, monitor and graphics issues etc. If the battery is not charged (from like letting it sleep too long), let the Mac charge up awhile afterwards.
Will not hurt the machine resetting if it's not broken.
Other related hardware problems (optional):
Check battery status: Hold option/alt key down while clicking on the battery icon in the menu bar, top right corner.
Magsafe: Use the correct/matching power supply charger with your Mac, not a less powered one from another Mac.

My macbook pro is probably only 2 months old and there is a buzzing/grinding noise coming from the left side of the laptop every time I open it. It may buzz 5 times in a span of 30 seconds then not make the noise the remaining time that it is open.

My macbook pro is probably only 2 months old and there is a buzzing/grinding noise coming from the left side of the laptop every time I open it. It may buzz 5 times in a span of 30 seconds then not make the noise the remaining time that it is open. I have read that it may have to do with my fan or HD. I am under apple care for a good amount of time but am wondering if this is a mjor issue. I would not be able to get to an apple care center in the near future due to being at school. Should I be worried or will it last by the time I am home in 2 months.

Sounds like the disk in your MBP is accessing data on wake up
If you are still concerned you can take it into the Apple Store where they can hear it to be sure

Mac Book Pro Retina crackling on the left side

Hi,
after over one year without any issues my MacBook Pro with Retina started crackling today on the left side.
Exactly like in this video (just on the other side):
http://www.youtube.com/watch?v=rx7Nwp9SE74
Does anybody know what it is and what to do?
Is it the fan?

Call a local person that can come and fix your issue, we can only help those who assist themselves and are a bit further experienced that your currently are at the moment.

Core 2 Duo Popping on Left Side

I have a MBP Core 2 Duo (4,1) that keeps popping on the left side. It sounds like it's coming from around the F2. It's getting more frequent and louder over just a short time. This all started maybe a month ago after years without a problem.
An Apple Genius looked at it in the store, and he could find nothing except that maybe it was the speaker. But the store is always so loud that I don't think you could hear a computer doing anything less than screaming.
This popping happens even with the speakers on mute, and I really do not think it is the speakers. There's no cell phone near it when this happens, and it happens anywhere, so I don't think it's interference.
It's not the hard drive as I have replaced that in the meanwhile, nor is this a hard drive sound.
The popping is a steady beat when it's happening. And it doesn't happen all the time. I can't really replicate the sound. It just does it's own thing. I do, however, hear it most often either when I have recently disconnected the power or when the battery is charging. (The power socket, however, doesn't matter.)
The really odd thing is, I seem to be able to stop the noise by activating the Mirror widget and/or SystemLoad (http://www.bresink.com/osx/SystemLoad.html). SystemLoad doesn't have to run for more than a second to make the sound stop — instantly. I don't know what that means, but it must indicate something, right?
Since I just upgraded my OS from 10.5 to 10.6, Apple has given me an additional 90 days of warranty. So, if there's something I need to try, I would like to do that soon.
Thanks for any ideas.

I guess I can't modify my post.... But I wanted to add this:
I don't think it's a fan hitting something as I blew those out when changing the hard drive.
Often, the volume of this popping is constant, but it's sometimes more LOUD-soft-tiny bit softer-LOUD soft-tiny bit softer. If I had to put it in numbers, I would guess 10-6-5.

How can i open the left side of the G4?

Hello!
Have G4 that is starting to sound like an aeroplane. I opened the four screws on the left side of teh computer but it still hangs on to the apple so I can not get the side off. I tried to pull a little but i is stuck.
How do I open the side after i have removed the screws?
There are a lot of dust bunnies/rats etc.
Thanks in advance
Per-Anders

There is a plastic stand-off, that's attached to the (inside) center of the side panels. When pressed into place, two tabs snap-lock the panel securely to the chassis. For the left side, removal of the internal fan assembly will provide access to these two tabs. Gently squeeze them together, and the panel will be released. To avoid breakage, don't use excessive force on them. The right panel requires removal of the logic board, to access the catch/release tabs.

Error code 4M0T/4/40000002: Left side -0

My computer screen suddenly wigged out while I was in the middle of surfing the web. When I restarted it, everything seemed normal until it wigged out again a few seconds after rebooting. Now When I start my computer the screen just remains gray. I ran a system hardware test and it came back with the error code: 4M0T/4/40000002: Leftside - 0 . Does anyone know what this means?

Apple doesn't publish a translator for the codes but, based on what had been posted elsewhere, I'd say your left side cooling fan motor is failing or has failed. The video artifacts are probably due to overheating of the graphics chipset. If the gfx chipset fails, it means an expensive logic board replacement.
To prevent any damage from excess heat, I recommend that you discontinue using the computer until you can get Apple to check it.

Left side cooling of MBP

My MBP 15" 2010 model heats up a lot only on the left side. is there a cooling pad / fan tray that will focus on cooling this side only since my objective is to even out the temperature of the whole laptop.

The left side of your MBP under the palm rest has the hard drive and upper left front is the dc in board. It is normal for that to be a little warmer than the rest. But if it is very hot , you might have a problem. You have two fans. one left center and one right center. If one of the fans is not working well or has dust or something clogging it. it could run hotter. If you download a fan app such as SMC fan control. You could see if both fans are working and what temp you are running. Here is a take apart that shows what is under the keyboard top cover.https://www.ifixit.com/Teardown/MacBook+Pro+15-Inch+Unibody+Mid+2010+Teardown/22 12

Left side noise (NOT BUZZ)

It seems that the left side of my computer is louder than the right. Can anyone explain? Fan control says I have both rans running at the same speed, uet it sounds like the left fan is faster. Hmm... Any ideas/similar expieriences?

My left fan seems to be running harder than the right. And the right has a whir to it. Screwed from both sides! Only bought it yesterday. It be going back.

PowerBook 17": Loud, loud noise eminating from left side on startup

After overheating last night, my PowerBook won't start up when plugged into the wall (with the battery removed). It does start up when the battery is in, but when it does, a VERY loud sound similar to an old-style modem making a connection comes out of the left side of the machine.
Anyone run into a similar problem?

Hello,
It seems that given your description, you will have to take your machine to a local apple service center. Only the technicians will be able to make a firm diagnosis f this particualr issue.
If i was cornered, i would say it could be several things however...such as the DC-in board, a faulty cooling fan, or even a damage/corrupt BootRom!(this is bad bad news)
Hopefully its not that serious, but i do wish you good luck in this case!
Sorry i couldnt be of more help,
Cheers

MacBookPro 2.8Ghz intel Core i7 running so hot on left side it burns my wrist when I type.

Hi: I have a 17" macbook pro. Left side where mag safe is has always seemed too hot to me, but I've been told that's normal. After running for upwards to 5 hours, the heat on the left side near the touch pad becomes so hot that I can not rest my wrist on the machine. I've got the screen in proper position (45 degree angle), the back of machine is not blocked. It's on a hard surface (desk or lap desk--because it is too hot to just have on my lap. The mag safe is functioning (power box) often is very hot as well and it is just on floor, not covered by anything. I don't understand what causes this problem and how to fix it.

1. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the appropriate method.
2. Runawy applications can shorten battery runtime,affect performances and
    increase heat and fan activity

Left side of Mabook Pro becoming hot

When I charge my new 2010 macbook pro 15 inch it becomes noticeably hot on the left side where as the right side is fine. Is this because the charger is plugged in on the left side. Is this abnormal?

[Look at Step 15|http://www.ifixit.com/Teardown/MacBook-Pro-15-Inch-Unibody-Mid-2010-Teardown /2212/2] and you will see that that is where the CPU and Nvidia GPU are. Those are the components that get the hottest in a computer.
Right now, at full load, my late 2010 MBP 15" has 90˚C i7 CPU, which is below the 105˚C max operating temperature according to [Intel|http://ark.intel.com/Product.aspx?spec=SLBPE].
Install [iStat Pro|http://www.islayer.com/apps/istatpro> (free widget) if you want to keep an eye on the temperatures inside your Mac.
If you are still worried, as many other people are, [SMC Fan Control|http://www.macupdate.com/info.php/id/23049/smcfancontrol] will make your Mac's cooling fans run at a higher speed.
