I've got this weird problem with my late 07 SR 17'' MBP, after I plug in the Magsafe charger the fans start spining and in like 3 minutes they reach 6000 rpm (both of them) and stay that way until it's finishing the charge. I did the same exact tasks with my laptop charged and plugged in, and the fans stay around 2000 rpm, as opposed to when it's charging staying at full speed.
View 5 RepliesSo today I opened up my MBP to clean it out and stuff (it had a ton of dust... A wall of it had built up where the fans blow out)All is fine and dandy now except for one thing. Since I don't want to open my case up for the second time today (right fan wasn't plugged in all the way first time I started it up... oops x( ) I'm asking here since everything else seems to be fine.
What I did:
Opened everything up all the way down to the heatsink.Applied correct amount of Thermal paste.plugged everything back in (right fan wasn't perfect at first, but fixed and stupidly didn't double check everything else while I was in there)
And now both fans are running at 6k (full) constantly. I tried resetting PRAM and SMC with no luck. I'm about to grab my disk 1 and run the diagnosis to see if that turns up anything.Are there any plugs that I might have accidentally not plugged in all the way or at all that would cause this? Also any other suggestions if everything is plugged in correctly?

Also, I have iStat Menu. No apps using all my CPU (Mostly <10% usage right now) and temp is mostly <40c right now. All temps have a temperature so I'm assuming all heat sensors are fine.On a great note: My computer is so much cooler now! Even before this at 6k rpm I'd get down to MAYBE 45c if I was lucky.I also have Fan Control installed and it's not having any effect
My step-son works for a company that uses a variety of computers in their test dept. and when they upgraded the test equipment they gave the old stuff to employees.My step-son is a dyed-in-the-wool PC guy who doesn't care for Macs so when he saw a G5 PPC sitting there he took it home and gave it to me.
It's a 2.0 GHz dual-processor with 8x AGP video. I checked it out and the only thing "wrong" with it is that someone has set up the fans, all of them, to run full-speed all the time.First, how did they most likely do that and, second, how can I return the fans to their normal operation. This can't be good for the computer and it's so loud and annoying that I'd rather use my G4.It's a great computer otherwise, I hope they didn't do something permanent that would require a new motherboard, that's not in my budget.
Brand new 2009 octo, with the 2.2x ghz CPUs. Turn it on, start NO apps. Let it sit idle. Within a few minutes the fans ramp up to FULL jet engine speed. I can't hear people on the telephone. And never stop. Let me reiterate that I am running NO apps. My load averages are in the zeros.

I've got a little problem with my iMac 24" 2.8 GHz Nvidia Geforce 8800GS 500GB. When I start it up, the fans start blowing at full speed. I checked the apple support page for support and found my problem with all the symptoms being correct. The support said I had to reset the SMC by shutting down the iMac, then removing the power cord and all the other one's, wait 15 seconds and then put the power cord and the other one's in respectively. I did this almost 10 times, but my iMac still won't stop making those annoying noises. Maybe it has to do with the SMC fancontrol app my brother installed lately.
View 2 Replies View RelatedMy PCI bay fan is running at full speed no matter what. The temperature sensor reads correctly in OS X, so I don't think it's a bad sensor.
Is there any way to set the fan speed manually, say in openfirmware?
It's a 1.8 DP June '04; I've ran ASD 2.5.8 to calibrate and test the mobo, which passed.
My Mac OS X as soon as I turn it on the fan is running. I have already gone thru the reset SMC . Could I have too much stuff in it?

I have a 1.8Ghz dual processor G5, 1GB Ram, 80GB HDD, with OS X 10.4.7 installed and all current updates, and today I was working on it and the fans on it slowly started speeding up, and then everything on the screen disappeared and a mesage appeared stating that a restart was required. After restarting everything seems to be working fine, but I'd like to know if this is a fluke or if I have a serious problem.
View 12 Replies View RelatedI have a 24" mid-2009 iMac, bought in June. It's behaving oddly over the past week or so. It fails to wake on sleep on the first attempt, but always succeeds on the second. When I say fails though, I mean that it *does* wake up, but goes back to sleep again after a few seconds. The other issue happened today, when I woke it up, in a cold room, the fans started up at full speed (I assume). It sounded terrifying to me as my iMac has never got that loud - not even playing games. I restarted it and it was the same, but died down after a while.

View 1 Replies View RelatedI have a late 2007 macbook pro and recently the fans have been going at extremely high speeds without the MBP being hot at all. I have SMCFanControl and iStat Pro and both of them said my MBP's temperature was around 55C though the fans were going between 4000 and 6000 RPM, I also checked the activity monitor for high CPU usage but nothing high there. I turned my MBP off for 5 minutes with a fan blowing on it just incase it was hot but when I turned it back on the fans immediately jumped back up to 6000 RPM. They're back to normal now but I assume it will happen again. Anyone know what's wrong?
View 12 Replies View RelatedI was just wondering if it's okay to run the MacBook with the max fan speed (6200RPM) at all times? It's really hot nowadays and my MacBook runs at about 60 degrees Celsius idle. If I run a few CPU intensive apps, the temperature usually rises to 70-80 degrees. This is with the fan running at max speed. So what I want to ask is, will it be okay to keep the fans running at max speed at all times? I'm going to get a notebook cooler soon so that should help with lowering the temperatures a little lower.

I've already reseted the PRAM, reseted the SMC. Turn off any sharing. But that did not help.

My Early 2008 MacBookPro 2.40 ghz 4 gb Ram OSX Mavericks machine's keyboard backlight off and fans run at high speed; it seems an exact smc resetting problem.
So i tried the 2 ways of SMC restting procedure; both battery you can move and not, but nothings changed on the situation..
On the way for removable battery; nothing changed but on the way for umremovable battery way; keyboard backlight flashes and gone, but fans are at high speed not changed. So nothing changed.
My Macbook Pro (13", early 2011, Core i5 @ 2.3) started to behave weird, its fan (only the exhaust one, since it's a 13" Macbook Pro with the Intel HD integrated graphics) is running at top speed (6200-6208 rpms) with no reason at all. No system processes consuming high CPU, just idling.There's a twist to this issue, though. It only does it when I open the lid more than 90 degrees. If I get it back the fan returns to normal functioning.What I did:checked the temperature sensor values, they are finechecked for crazy background tasks, there are none, CPU usage is at max 7%it does the same thing even in safe modereset PRAMreset SMCreinstalled OS X (Lion). Updated to 10.7.4searched every discussion I could find on this matter.
The difference between this issue and others I encountered along the way is the lid opening thing.Does anyone know if getting the lid past the 90 degree mark triggers anything?The other theory I have is that there's some dust blocking the intake and when the lid is opened wide, the air is somewhat obstructed by the bottom of it.

I am interested in adding a webcam to my desktop Imac (power pc)- Isight is no longer available- an option that I found is the Ecamm Image- but apparently it is USB and not firewire and it will only run with high speed usb- how do I know which type is on my computer? I checked system profiler but quite frankly wasn't sure of the designations.. does anyone have any experience with this camera, by the way? is USB 2.0 by definition "High Speed"?

My mac has always been fine only getting up to about 70*c when encoding. Now it gets past that when doing nothing, and fans going full blast! Tried every mac temp. software. Looked in activity monitor, nothing major running, biggest thing is "activity monitor". I can just have it sitting on my counter, on hard surface, very hot fans full blast. Its a new MacBook White early 2009.
View 8 Replies View RelatedI have a white MacBook and its three years old. It all of a sudden crashed last night and when I switched it back on the fans were running full, the time set to 1-1-2001 12:00am and there is an X through the battery sign. When I click on the battery charge symbol it says " No Batteries Available" although it clearly does as it runs without needing a charger. And then there’s the fan.
It started running at full speed (like I was playing a game or something) and it just runs like that all the time. I have restarted my computer and shut it down several times and the only problem fixed is the time. Also when the screen is shut it doesn’t go to sleep or even show signs that the lid is shut? I haven’t done anything to dislodge the sensor so I don’t know what the problem is.
I only started noticing my fan running a bit on the fast side this evening after installing the new Safari 4.0.5 update. I looked at iStat Menus for temp and CPU. And I was seeing about 190 degrees F for CPU temp with lid closed running ext display. Also there was a constant usage of the cpu (about 30% User and 20% System). There's not one particular process I can see in Activity Monitor that acting out of the ordinary and using a lot of CPU. Just stuff like coreservicesd, WindowServer, launchd that are shuffling around and using about 1-4% of CPU.I ran repair disk permissions and verify disk. Verify Disk found errors and said I need to repair my Macintosh HD, which I have now done successfully.
View 3 Replies View RelatedI recently picked up a 17" 2009 unibody MacBook Pro with Intel Core 2 Duo 2.8ghz, 4gb RAM, SuperDrive and a Samsung 1TB hard drive. The system did not come with the original hard drive and I don't have any other hard drives to test and verify that the new larger hard drive is the cause. I have tried a clean install of Snow Leopard, Lion and even Mountain Lion but no matter what my fans always running at max speed (5k+ RPM). I have looked at iStat and the temps of any of the components in the machine never show more than 42*C so the fans should never be running at full blast. Oddly enough smcFanControl shows 0* temp but fan speds for both left and right are always 5.5k+ and very noisy. Using HDD Fan Control I am able to get at least the right fan to run at a controlable speed but its silence is drowned out by the left fan that still runs on full blast. I have already done multiple SMC resets and PRAM resets with no change in the condition. These noisey fans are driving me insane! I have run every available update as well. Is there a chance that the hard drive or something elses temp not being supported or detectable by OSX is causing the fans to default to the fail safe constant high speed?!

Then I can reboot work for half an hour until battery is like 50% then it shuts off again... then I can reboot again and work for some more time. I've checked with coconut battery and when the computer stops at 70% I still have like 1700 mAh...I've reset PRAM, power management, etc...
Of course my battery is old, but it should work until 00%... not stop at 70%. Before I spend like 100$ (that is what a macbook pro battery costs here in Mexico) I'm willing to try anything...
I recently was given an old 2x1.8Ghz PPC G5 in order to build a personnal server but I have troubleshooting with CPU's temps that are really too hot (75?C with no app open, only Finder).
I know these temps are not that "hot" but I can't imagine what it would be when I'll open Safari, iGetter, iTunes, CyberDuck, Adium and Photoshop CS4...).
I first unmount everything, blown inside some bottled air to make sure there were no dust creating overheating inside and remount everything.
Installed Leopard (last OS installable on PPC machines), made the last updates possible and restart.
Everything is working well althought this CPU's temp is so damn high and fans's speed are still at 300rpm. I was looking for some app that would do the same as SmcFanControl for Intel based Macs but for PPC's ones.
After many internet searches on many forums I finally admitted there were no software able to set fans's speed, the only way was manually editing the AppleFan.kext integer's values.
WhatI did, reducing the integer values to lower rates (256x multiples), then restarted the Mac but nothing happens. As I check the changed values, they indeed are the ones I edited but the fans still are at 300 rpm and the CPU's temp 75?C...
Does somebody have any solution for that issue, I feel I checked everything that was possible but nothing seems to work.
My PowerMac G5 fans hardly ever speed up. I mean they certainly never go full speed or ever close how they sometimes behave on start up. I never get the jet speed noise. Even when I am rendering a movie in FCP, I hardly hear the fans. Right now on idle, iStat pro reports CPU A being 58C and CPU B being 56C. Yet, the fans are still only 400RPM both CPUS Intake/Outake.
View 4 Replies View RelatedMy CPU heat sink fans always run above 2000 rpm. Is that avoidable?
Can I do something about that to drop the speed and get rid of the noise?
During the summer, I don't have A/C in my house. My temps were getting pretty high, around 55C/130F for processors and up to 78c/172f for ram. That is pretty high, and I suspect it is because the ambient temp in my room is somewhere in the 90s. I am just very acclimated to the heat, and it doesn't bother me.
I downloaded SMC Fan control and bumped the min fan speeds up to:
1250rpm for Exhaust
1150rpm for CPU
800rpm for Power Supply
1350rpm for HD
This has made a tremendous difference. CPU is down over 20C and ram is down about 30-35C. Are these fan speeds safe? What are the Mac Pro fans rated at, and will the increased speed shorten their lifespan? I'd like to keep these current fan speeds if it is safe.
