PowerPC :: G5 Fans Constantly Running At 4K
Jan 19, 2009
My PowerMac's (G5 Dual 1.8GHz procs) fans seem to run at a solid 4k rpm's regardless of what I'm doing, even with CPU usage set to low. I've taken the whole machine apart, cleaning it with canned air and such, but the problem just won't leave me be. The air coming out of the machine is ice cold, and the temperature readings I'm getting are about 86 degrees F for the CPU's and 70 for the HDD, so I'm not sure what gives.. Slot and Backside fans are running at 255 rpm, but the others are all 4k.

What is wrong with this picture? The fans are running out of control constantly. This machine is sooo loud. The power supply was just replaced, which did little/nothing. Reset all ram/etc.

I've just bought a second hand macbook pro, the battery is dead which is easy to replace i guess but worse the fans are running constantly at around 6000rpm.I've tried resetting the smc and pram but that hasn't helped.I tried to run the hardware diagnosis but that freezes when it gets up to testing the logic board and i have to pull the power adapter to turn machine off.I only have the second of the two install dvds and machine is running os x 10.5.8

I noticed that my GPUs fans (either ATI 3870HD or 4870) in my MP 1,1 are considerably louder nonewithstanding nothing CPU/ GPU taxing is running. Anyone else noticed this? Are the GPU drivers not finished yet or is it due SL keeping them under load for Open CL/ Grand Central?

I need the thoughts and advice from your seasoned Mac people - I have 2 MBP's - 1 15" aluminum, one last years model 17" Unibody (with Black around screen). The 15 has run great since day one. The 17" was ok, but now is locking up and causing me to reboot, fans seem to run on high all the time, and it is very slow to react while using the OS, it gets worse until it locks up. I have upgrade to Snow Leopard thinking that that might fix it, but it has not.
When I got it, I restored from the back up of my 15" using carbon copy cloner. I only imported users and data such as pictures and music. Do you guys think that this is a hardware issue or a or should I back all my stuff up and then blow everything away and reinstall from the ground up with a fresh SL install?
When I called apple they tried to sell me apple care and told me that it was out of the full warranty and if I send it I would to pay for what was not under warranty. SO I am hoping that someone has seen this and has a fix that I can do without having to take it in.

My fans are constantly going on my g4 powerbook and the noise drives me nuts. I do all sorts of work - graphics (CS2), music recording, multimedia... but even when I am just not doing anything intensive the fans are on.
The fans are at full speed now and the temp reads 37C / 98F. I've used an icurve since I got the machine.I've put up with this noisy sound for a couple years now. One person said I need to clean the air vents, like dust is causing the noise. Does anyone know about this?
its a g4 titanium powerbook 867 mhz 768 RAM (ancient I know but it still works!)

The fans on my G5 Pro are running at close to 3000rpm most of the time. I have read other forums and do not think this is normal at all. I started looking into the fans because I am getting frequent kernel panics (black screen crashes) and thought it might be the machine over heating. My CPUs are at about 50C to 52C and the fans are constantly running that fast.

CPU cooling fans are running at strange different speeds. Powermac G5 early 2005, dual G5 (not dual core).This is at idle:CPU A 60 degree Intake 300rpm Exhaust 300rpmCPU B 63 degrees Intake 1125rpm Exhaust 1100rpm! I have not noticed this before. They usually remain identical.

Both my left and right fans are constantly running at 2000 rpm. They have not done this before, but over the last week I have noticed this issue. Heat does not seem to be an issue in triggering the fans. I'm so confused on why they're are constantly on now.No CPU hogging processes or high temperatures.

I've had an iMac for just about a year and over time I guess I just didn't notice but the machine always ran very quietly. At the same time the back of the computer would heat up so bad that it would nearly burn my hand if I left it there. Well last week I decided to upgrade to Lion from Snow Leopard and when I did the install failed and froze up the hard drive. I took the computer in to the apple store and they determined that it had to have a new hard drive installed because the old one (only a year old) had a physical malfunction (was broke). So anyway I have my iMac back and get it started up, backed up from time machine, and then finally get Lion istalled - and now all of the sudden I notice that the fans in the computer are CONSTANTLY blowing - I can hear them spinning and can hear the air venting out of the back of the computer - and the computer is STILL really hot on the backside of the screen. Â
So now I am wondering if the originial problem was the computer heating up and if that may have broken the otherwise good hard drive? Also now that I have a new hard drive - should I be concerned about the fans being on ALL the time? I mean they never go off. Even when I leave the computer for hours and come back to it and the screen is asleep the fans are STILL buzzing away at top speed. Here is the stats on the computer at the time that I'm typing this note - there are no other programs running than Firefox and Mail. Also - I don't know what the optical drive is exaclty - but if it's the DVD drive (superdrive) - there is nothing in the DVD disc driveÂ

My parents have an older 20-inch white Intel iMac that has run great through the years. But about a week ago it just started spinning the CPU fans up to 3500-4000 RPMs and it won't bring them back down. Istat shows that the CPU temp is around 90 degrees and the computer remains cool to the touch.
So it isn't overheating. My parents keep it off most of the time because they don't want to ruin it, but they're planning on using it in their business they're trying to start up. We've done some web searches and nothing seems to fix it.

Since I updated to 10.6.6 earlier today I've noticed that the fan in my MBA (13" late-2010 model) is running constantly. This is rare -- I hardly ever hear it. I opened activity monitor and 'System' is using 45% CPU time, and it's pretty constant.
I have absolutely no clue why -- there's nothing in console to suggest it's doing some task, and I can't see any other hints. Apart from the noise and the heat (though don't get me wrong -- compared to my old MBP it's not really noisy or hot, but I liked it better when it was totally quiet and cold), it's also killing the battery -- 25% has gone in less than an hour.

My OWC RAM is working just fine, but I am growing increasingly concerned about the temperatures at which it runs. I have the 3.0 (120W) MacBook 2008 with 18 Gb RAM (4x4Gb + 2x1Gb apple stock). The RAM in memory module A2 & B2 is getting up to 80 Celsius without even much of a workout on the RAM. What's more, the MacPro fans are not increasing - right now the hottest module is at 76 Celsius and fans haven't increased at all (see screenshot below).
I have installed SMC fan control, which I understand is supposed to set the minimum fan speed, which I have set at 730 because my RAM was running hot even without any workout. How concerned should I be about this? Is this a) a defect in my mac pro b) a design flaw c) a problem with OWC memory, or d) is everything OK and I'm making a mountain out of a molehill?

Well my MacPro 2009 has this weird error where the fans will kick in and a restart wont restore them to normal a sleep cycle will though. It seems to only happen with OpenCL intensive apps but not Cuda intensive apps?? this may be random coincidence.

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.

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.

Like 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.

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.

Last summer my MBP 2.3 GHz C2D was heating up so much, you barely could touch it. So I decided to give it a little hardware checkup. Finding the fans completely stuffed with dust
But after a while i recognized that the fans went on high rpms (around 6000) already at startup and did not lessen anymore. I do not have any high capacity processes running and the temperatures are not just not warm buth rather chilly, so no need for high fan speed. Now I want to solve this problem as well but seemingly nothing will work.

My iMac (intel core duo) after a hard drive replacement seems to be running the fans at a high rate of speed. Usually just a few minuets after startup. Before the upgrade they were almost silent and now they are very noticeable. I need to get taken care of or just a result of installing a larget hard drive?Â

My fans have always been running at 2000 RPMs. I downloaded an app from the mac app store which caused the CPU to overheat, and in order to control this I read that it was wise to download smcFanControl. I downloaded this and added 2 settings, 2.4K RPMs and 2.8K RPMs. This worked to cool down my laptop, and once I realized that my CPU is at 36 degrees Celsius, I set the fans back to the default settings at 2000 RPMs. Now, my fans are constantly running at this speed according to smcFanControl and iStat. My core is cool, not even warm, yet all I can hear are the fans spinning fast to push hot air out of it, when there is none (I've put my ear to it to hear and feel the heat, there is no heat coming out).
I've had this laptop for less than 24 hours, it's a:
15' Macbook Pro late 2011
Intel Core i7 Quad Core 2.4gHz
7200RPM 750GB HDD
Also, this was not occurring prior to downloading smcFanControl (I've turned it off, deleted it, nothing works) - Even after turning off the laptop, the fans stopped, automatically after turning the laptop on the fans came back on. Some extra information: When I put my ear to the bottom of the laptop, it sounds like a vibration.

I 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 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.

It's the 2008 model MacBook Pro with the 9600m gt 512 card.
So, I just noticed that when I have my MacBook Pro in High Performance mode it emits an high pitched noise when the fans are running around 6.2k RPM and the CPU and GPU is around 63c. The noise follows the speed of fans, and at idle the noise is gone.
I have uploaded a video of it on youtube here: http://www.youtube.com/watch?v=HioRgTNpNRA

For the past couple of weeks I've noticed that my old white macbook is running hot, and browsing has been kind of slow. I don't see anything out of the ordinary in the processes, but Heatsink A is reading -1. Should I just pull the machine apart and see if something isn't connected anymore? I installed a 7200 RPM HD a few months ago, but this problem is more recent.
