I have a late 2009 Macbook Unibody that get extremely hot. From using SMCFanControl it tells me it's at 80-90 degrees celcius which to me is extremely hot. The fans also do not kick in at all when it gets at this level. When using skype, it skyrockets over 100 degrees celcius which causes my computer to slow down.
Is anyone else having this issue? Do you think it's a hardware malfunction?
I'm trying to record something through the internal mic (and I'm too cheap to go out and buy a proper mic) and I was wondering if there is anyway through Terminal,or an external program, to force the fans to shut off for a certain period of time? I don't want to turn them off to find they can't turn back on and suddenly the computer is 1000�...I just want to keep them off to have a minimal amount of background noise. (And, yes, I'll be running it in a moderate climate so the computer doesn't overheat).

My parents recently bought an iMac. Yesterday my mom was playing a game when the computer froze. Neither force quit or holding the power button was doing anything so in her frustration she unplugged the system. Today, after plugging in the system again, it won't turn on.
I press the power button on the side of the wireless keyboard and the green light on the keyboard turns on for about 3 sec and then starts flashing. No fans start up and the screen does nothing.

the other day i wake up and open my macbook pro and immediately heard the fan making noises ive never heard it make before. i checked istat pro. the fans were going at 2000rpm. this is when i started to get concerned since i would never hear the fans at that speed before. the difference was day and night. it sounds like the one or both of the fans are hitting something. i always hear the noise when i start up or wake up from sleep and after a while (30 minutes to an hour) it usually goes away but has come back once without me turning off or putting the computer to sleep. its a refurbished less than a little more than a month ago. im hoping its just some dirt that made it through keyboard and will eventually go away because i dont want to send my machine in to get manhandled by apple repair. has anyone had something like this happen before?

I have a problem with my 17'' MBP unibody:
1) Bluetooth is ON:
I can't turn it off. The checkbox is inactive.
But I can turn it off, if I choose "Share my internet connection for other units". (I don't know, if this is the right text in english, because my OSX is in german)
2) Now Bluetooth is OFF:
But I can't turn it on, because the checkbox "ON" is inactive.
It turns only on, if I choose "New Unit"(?). Then there is a new window, that says, that this is only possible if Bluetooth turns on. If I say OK, bluetooth turns ON.
Back to 1)
What's the problem. Why is this f* checkbox for turning bluetooth on and off inactive?
This is not a hardware problem, because I can have stable bluetooth connections.
I did a smc and am pram reset. But it doesn't help.
So lately I've noticed my Macbook Pro to be quite noisy. According to iStat menus, the fans seems to always be running at 4,000 RPM, even if I am just staring at my desktop, with nothing open.
They speed up normally when the CPU is under load, but they never go lower than 4k.
I tried using SMCFancontrol to restore the default settings, but they still run fast. I even reset the SMC the other day hoping that would fix it, but it didn't.
I've checked activity monitor and used a few terminal commands to check for any processes that are causing high cpu load or anything weird, but I haven't found anything.
I saw a single post somewhere on these boards about something called "coolbook" which is a utility that undervoltages (is that even a word?) the chip to make it run cooler.
It's $10 to give it a try. Wonder if anyone with fan issues would give this a try to see if it changes the heat/fans much?
Google coolbook and you will find it.
I've been advised to clean my MBP fan's out with compressed air, since I've owned it for 6 months now. So my question is, where would I actually spray the compressed air without opening the chassis? I'm scared to use it on the keyboard because I've heard keys popping off that way, and wondering if I spray into the vent below the screen, I would just blow the dust deeper into the computer...
View 24 Replies View RelatedMy Unibody 17" MacBook Pro (10.5.8) Is having a few issues that I cant figure out how to deal with.
I got this laptop I think in April. And a few weeks ago I noticed the a loud humming noise that wasnt there before. It seems, after finially looking into this problem, that my fans are running at full speed from the second I hit the power button, right until the machine shuts off. I installed istat and it says the fans are running at about 5700 rpm. I guess the good news is that It doesnt ever get warm. Although this fan noise is kinda annoying and Im worried it will burn out the fans before their time.
Also some time later I realized that the backlight on the keyboard didn't work and I couldn't get it to turn on manually. As well as the auto brightness adjust for the screen stopped working.
I have installed labtick and the keys do light up with that program (although I liked it when apple did it auto for me)
I read some threads here and really thought I had it with the reset the SMC. But to no avail. I also tried resetting the PRAM, which also didn't help.
I'm not sure If any of these problems are related or If this is just the most bunk MacBook Ive ever bought.
I have the new unibody 17 MBP 3.06. The unit doesn't get hot and I love it, but my fans run at a constant 3300-3500 rpm (istat and SMC fan control). The lowest setting on SMC is 1000 rpm I wanted it to run around 2000, but when I set it up the fans rev down then 1 second after revving down to the slower speed run right back to 3500 area. Is this normal? I thought SMC was to override the apple settings. Just 2700 rpm's makes a sound difference on my MBP. I was in a rush and forgot to mention that I just added SMC. I have had the computer for a month now and istat pro had it at 3500 rpm since I have gotten it and that is just surfing the net and at an idle. Since installing SMC Fan control didn't fix it I am wondering if I should take it in to an apple store or not?
View 1 Replies View RelatedI realize this probably wouldn't work due to the different smc controllers, but I'm wondering if the nice quieter 17'' mbp cooling fans would fit in the 15'' mbp's. Does anyone know if the fan sizes are the same? I know that the model #'s are only one letter off. The 17' mbp fans are quieter than the 15 due to having fewer blades(?) or a different design, and I think they actually spin at a lower speed. This would probably be super dangerous as the 17'' fans might not be compatible with or do a good enough job of cooling the 15'' mbp effectively, but it would be a cool mod. Anyone have info on the feasibility?

There is no heat problem anywhere. In fact after an hour or two of running I opened the case and everything was cool to the touch. Not even warm! Is there a way I can get the fans to slow down?

I'm pretty big on silent pc's (need dead silent, love my curr ssd), wondering what apps gets the fan going?

I was noticing a lot of slow-down while playing computer games on my MBP. My computer far exceeds the minimum requirements for everything, so I reckoned it must have been something other than a slow processor (2.53 GHz Core 2 Duo), low ram (4 GB) or a completely inadequate graphics card (Nvidia 9400M). The games range from 'Day of Defeat: Source' to the 8 year-old 'Return to Castle Wolfenstein'. After a bit of research, I came to realise that my exhaust fan is never speeding up past 2005 RPM no matter WHAT the load on the CPU is. To test this, I downloaded smcFanControl and ran CPUTest. As the CPU went from 50*C to 95*C, there was hardly any change in the fan's speed. The variation went between 1995 and 2005 RPM.
In order to keep the computer relatively cool when playing games or doing anything that is CPU-heavy, I have to manually increase the fan's RPM in smcFanControl. I find that setting the fans to the maximum, 6000 RPM, keeps the computer cool enough to process these games. This program works wonders and I've not had any slow-down in games as a result. However, I am worried that there might be something wrong with my Mac. Why does it not automatically increase fan speed when reaching higher temperatures? I've even reset my SMC (SHIFT-CONTROL-OPTION-Power) on start-up just to be sure I've tried everything. Any suggestions as to why my fan seems stuck at 2000 RPM?
MBP, 13-inch, 4GB RAM, 2.53 GHz
Both of my fans are running at the max 6200 RPM and have been for well over an hour. My CPU is over 65% idle, and none of my processes are over 20%. My HD Temp is 38 degrees and my CPU temp is 72 degrees. I don't think my fans should be running this high considering the computer is doing so little work.
View 24 Replies View Relatedusing Ichat the other day running a full screen chat, and I saw the temp of the CPU rise to about 65C and the fans started spinning up 6200.... That was understandable as the CPU was under load... but after I closed the ichat down, the CPU temp dropped down to about 50C but the fans stayed at 6200 for a long period of time. probably about 10 minutes or so... then they slowly crepted down to 2500.
View 15 Replies View RelatedMy MBA is 1.6/80. The fan does not work suddenly and stays at 0 rpm (istat pro, smcfancontrol), no matter how many times I've restarted it. I've been using coolbook to adjust voltage and smcfancontrol to adjust the max fan speed, but do not think it is really the culprit as there are other reported cases online. I've run the hardware test and there was an error shown: "4MOT/1/40000002:Exhaust-0". Also it shows in the activity monitor the UserEventAgent(117) is not responding.
The weather in the UK now is around 13 and the temp of my MBA is hovering between 62-70 C (istat-pro) in-door all the time, just surfing the net! I've been loving this machine up till the moment the fan stopped. It is really frustrating as this is my first intel mac, and the fact that i'm relying on it for preparing notes for the approaching exams makes it even worse. I really doubt its reliability at the moment.
My fans are stuck at 6200 rpm. I downloaded SMC Fan control and have my minimum speed set at 1500 rpm. I checked my activity monitor and there is nothing taking up a large amount of my cpu. My temp is around 60c-70c on average, which is normal.
View 4 Replies View RelatedJust been having some pretty big issues with my late 2007 Macbook Pro.Basically, the other day I was playing World of Warcraft, when my Macbook ran out of juice. I plugged in the charger, left it for a few minutes, but no, it wasn't going to wake up again.
So I turned it off, and that was basically it. It wouldn't turn on again, regardless of whether or not the charger was plugged in. Eventually I got it to boot by doing an SMC reset, but now the fans run at 6000RPM and it says it's at 0C and the fans are running at 0RPM.Which is making me believe that the temp sensor is screwed.
Also, it no longer detects my battery, and Windows simply doesn't boot. Mac OS does, but again, I get these issues. System profiler says that my battery has 0 capacity, 0 charge cycles, it is not charging, and it's essentially dead. However, if I unplug the charger, the Macbook continues to stay on, though I can't say how long this is for.
I'd also like to make it clear that the fans start running at this speed from the second it starts up, right before the grey screen appears.I've tried PRAM and SMC resets multiple times with no luck, and I'm wondering if the logic board is just partially fried or something.Hopefully you guys can help me, and no, it's not under warranty, though I do have home insurance which has covered this Macbook before after it got sat on and the screen was crushed.
I own a Macbook pro 17" core duo 3.06Ghz. I am very happy with the machine, but since a few months the fan's are louder and on much more often then ever before. (the first half year it was always silent) I remember there was some reset for this.
View 2 Replies View RelatedLike 3 days ago I shut down my macbook pro normally. I closed the lid and I noticed that the sleep indicator light was on. I opened the lid and the light went off. I closed the lid again and the light went on again. I got closer to the computer and the fans and drives inside were still running. The only thing I did was to hold the power button down until it shut. This has happened to me 3 times already. I'm kind of worried because I got the computer 2 weeks ago and I'm really happy with it. My computer is a 2010 13' Macbook Pro running Snow Leopard, not sure what version it is.

View 11 Replies View RelatedI am using a 2006 MacBook Pro, 2GB RAM, 2 GHz Intel Core Duo with a 500GB HDD that has 450 GB free.About a month ago the left and right fan started cranking up to 6000 RPM (which is apparently max for this model) upon startup. Most discussions I've read while looking for a solution suggest resetting the SMC, which I have tried a few times to no avail. CPU and RAM usage are normal, nothing taking up tons of processing power on activity monitor and temps are around 35-40 degrees Celsius. I saw a few boards talk about a stuck print job which I checked for as well, but there was nothing. I tried downloading and using the smcFan Control app and setting the preferred fan speed to as low as possible but the app still registers speed at 6000 RPM and they have not slowed down. Unfortunately, I bought this MBP from a used dealer (had it for a few months before this started), so I do not have the original OS disks to perform a hardware diagnostic. It came with 10.5 on it but I have since upgraded to 10.6.8
I'm not experiencing any problems with operation but the fans at this speed are extremely loud and annoying; is there anything further I can do to try to fix this? I'm a bit new to macs, is there a program that gives you more powerful fan control than the one I downloaded? How much would something like this cost to get fixed by Apple?
