Fan runs almost continuously

I recently bought a Mac mini & it seems as if the fan is running far more than expected - like almost all the time. I've tried repositioning it vertically, horizontally or in different locations without noticing any difference. Is this something others have experienced?

Re: "&amp" : It means I wrote this on my iPhone and didn't proof what I wrote before I posted it.
Please explain what I am looking for on the Activity Monitor? Is it the CPU or Energy tab that I care about and at what point does the fan turn on? Is it 50% CPU usage or something like that?
Thanks for the suggestion as I didn't know this existed to even look at it.

HP Pavilion dv6 2122eo fan running almost constantly

On my now 12 month old HP dv5 2122eo running windows 7 64-bit home edition, the fan runs almost constantly, and has done so since purchase, even without any load on the pc.
Installed programme Core Temp to see temperatures, and the fan runs even at a temp. of 41C. Bios has a function to disable fan from running all the time, but even after disabling this in Bios, the fan still runs almost constantly. Would be grateful for any help/suggestions. This seems to be a problem for this pc when searching for solutions on the Web.

Andrew,
You can't control the fan speed/function directly on HP laptops. If you haven't updated the BIOS then try that. Also, here's some other stuff to try.

New MBP seems to run hot & fan runs almost all the time

I've had my MBP for just about a week now. It's the new, 15", 2.2 GHz model. It's great, but I notice that it runs hotter than my Powerbook G4 did and the fan is almost always on. It's presently sitting on a wooden topped table. My house is not AC-ed, but the air temp is about 70 F/21 C today. Seems to run hot in my AC-ed faculty office too, when I am there. What is "normal" for this machine. TIA.

David,
Ditto what Ned says. To be sure, 80 C is not too hot (it is the temp that the MBP is designed to maintain as a working maximum), but that you are experiencing this temp at all times indicates that something is pushing the processor at all times.
That is not normal. As has been suggested, have a look at Activity Monitor. If you are not doing anything of any consequence at the time, your CPU usage should be very, very low, and processes that you see using CPU intermittently (there will be many of these processes) should only use a small percentage when they use any at all.

17" MacBook Pro fan runs almost constantly

Fan runs way more than it use to and the screen becomes pixalated when waking up from screen saver or switching between desktops. The fan seems to run when searching the internet. Is the video card going out possibly?

Very real possibility.

Try a SMC reset:

If there is no change, run an Apple Hardware Test:

The fan runs almost constantly but is not hot

My macbook pro is making a fan-funning sound almost constantly, even when the computer is not hot. I have tried shutting down and restarting, to no avail. Any suggestions?
Thanks.

As leroydouglas mentioned, the fans are always running, the idle speed is about 2000 rpm, if your fans are running at high speed when the machine is not working hard you can try a Systwm Management Control reset:

Follow direstions for a battery you should not remove yourself

Fan runs almost constantly-why?

So my macbook is about 2.5 years old, going on 3. I will admit that I don’t turn off my computer that much. I just close it for the night. However, my fan is been going kind of crazy for a while now. It’s okay for the first little bit it’s open, but then if I open certain websites or watch videos my fan goes at full speed and then won’t stop.
Is there anything I can do? Or do I need to take it to an Apple store?
thanks.

Another thing to do is to open activity monitor and sort the items by the amount of cpu that they use. If an application is using too much, you can quit it. If it only runs when you use safari, reset it.

Fan runs all the time?

I just bought a dual G5
the (very loud) fan runs almost 100% of the time when I have a CD in (I've been installing software and also tested it with a regular CD). Is this common? It is annoying for sure...any suggestions? chris
G5 Mac OS X (10.4.4)

I think you are confusing the noise from the CD drive with fan noise. When you insert a DVD or CD, it spins at up to approximately 10,000 revolutions per minute. This is definitely going to cause noise, and is likely what you are hearing. Don't worry, this is completely normal, and is the case with every fast CD drive I have ever encountered.

Fan runs constantly after installing replacement battery

I received my replacement batteries on a timely basis, charged them as instructed and get proper running time from them.
My issue is that suddenly the fan runs almost perpetually. I have zapped the PRAM, stared at the console utility looking for a problem, and watched activity monitor. All seem normal.
The CPU now runs at 140-142 degrees all the time. It would spike there occassionaly before but only when I knew I was pushing hard. Even connected to AC hoping that will vent the machine better has not helped.
Is it the replacement battery or just coincidence? Suggestions appreciated.

You might also try a different battery if you have access to one. Unfortunately, many of the replacement batteries being shipped by Apple are defective. They don't fit properly into the battery bay. I suspect that if the quality control is this poor, then it seems likely that other problems will arrise as well. Check carefully that the battery itself is not overheating. Another possibility which also happened to me is that after installing the last upgrade to the operating system, one or more of the third party widgets became problematic, causing the same problem you describe. After removing all third party widgets, the problem stopped. Good Luck

Cooling fan runs constantly on Tecra A3

I have a Tecra A3 an my fans runs constantly, even when idleing, and it has done this since i got it (about 18 months ago). It also runs at a constant rate, and it's just like hear Arnold talk - very annoying. Sometimes one (?) of the fans stopp running for just a couple a seconds, and then it starts again, back to the same speed. I've had the computer in for repairs, and they changed the fan and cleand the cooling system, but this didn't make things better, well, okay, I got rid of the ratteling sound, but that was all!
I've tried everything i can think of, currently I'm running the computer fixed on the lowest setting for the processor speed and battery optimized cooling by the help of the Power Saver utility, but it doesn't seem to help at all. I also tried setting the processor speed to low in the BIOS setup, this made some difference, and the fan stayed of for periods of up to 30 seconds (!), bur the performance of the computers performance was horrible with these settings so I had to change it back to dynamic processor speed.
As for the the temeratures i get at temperature of about 36-37 degrees celsius (95-97 degrees Fahrenheit) for the HD temperature (using speedfan). So theres no problems with overheating (?). This leads me to believe that this might be due to a bug in the software. I'm currently using a norwegian install of Windows XP with SP2, it's a custom install, provided by my university (my computer is a student PC bought through the university).
So, can anyone help my make my computer quiet, like normal, sane computers ?!
Thanks in advance for any help!

Hello Stigs
I use Tecra notebook (M1) for years and I can tell you that this model is really one of quietest notebooks I know but it is definitely no utterly quiet and cooling fan runs almost constantly but on slowest level. I know that it has nothing with your problem but I just want to say that quietest notebook produces noises.
Reading your posting I can just say that you are probably right when you say that it can not be because of hardware because the notebook temperature is OK and there is no sign of overheating. The fact is that all newer notebooks are louder than some old models and Tecra A3 is one of them and unfortunately there is no much to do. As far as I know nobody has reported about any software bug till now. Many bugs are fixed by BIOS updates and all I can recommend you, is to check if new BIOS version is available and see if this can help. Please before you start with BIOS update read carefully Instructions how to do this.
Good luck!

Finder makes fan run loudly and continuously.

I've had my MacBook for only a few months now and I am having a problem with the fan. It starts running loudly when I am doing simple tasks, such as viewing a webpage which contains no flash, video, or similar content. The fan does not stop running unless I put my computer to sleep or restart it. I have found that by relaunching the Finder, the fan almost instantly slows down back to its normal state. This concerns me as this has been occuring more frequently over the past two weeks. Is there some sort of fix to this instead of having to relaunch the Finder every time?

Yes you can continue to play games but heat is the bane of electronics and in time there will be a cost. When is hard to say, but I can put it this way, a fan running constantly at high speed is more likely to fail sooner than one at a slower speed.
Ciao.

Imac (Intel based) fan runs continuously and loudly.

Have done a SMC reset, and the fan is still running loudly and continuously. Only 1 application open - firefox. This has been an ongoing, continuous problem.
Thanks in advance for any help you might offer.

Have had the same problem .. have reset the PRAM & SMC, doubled the amount of RAM. Fans runs & Activity Monitor shows most of RAM is used up with nothing open. Running Snow Leopard 10.6.8 on a Mac Book with 4g of RAM, Apple Support showed no hardware problems. ????

Whenever I run Firfox 4.0, my computer fan runs continuously. I have disabled all plug-ins, and I get the same result. This did not happen with Firefox 3.x, and it doesn't happen with IE 8.0. Any ideas?

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

Fans run continuously @ 6000rpms

I just got a new 17" Unibody 2.66 and the fans run continuously at 6000rpm.
For example, right now they are running at 6000 w/ temps of:
CPU A - 35
GPU - 36
GPU Diode - 38
GPU Heatsink - 30
This is on a clean install with only Safari running.
What's the deal?

There could be some problem that doesn't show up on the AHT, like maybe a loose mounting screw or some tape interfering with the air flow or something along those lines. The fans should be silent when idling. So my guess is that there is still something wrong, but it will take someone actually opening it up and looking. It sounds like a mechanical problem of some sort.
Ironically, "mooing" was a problem with the first original MBP's that came out.
I think it's time to take your MBP into an Apple Store or call Apple to have this looked at.
Good luck!

Fans run continuously on my iMac(1 day old)

I don't know whether anyone might be able to assist, but the fans run continuously on my barnd new 27" iMac.
I have upgarded the HD to 3 TB anf the ram to 12 GB.
I have reset the smc some 4 times.
I do not know what else to do.
Any suggestions are most welcome.

I second Paul_31. If you haven't called Apple by the time you read this, you ought to do it now. You have a brand new machine. Don't try any more "fixes" until you call Apple.
Equally as important, whether they replace the machine of fix the one you have, you really ought to consider purchasing Apple Care. It extends the warranty to 3 years and gives you access to tech support for the additional time period at no cost.

Fan runs continuously after Update to Leopard

Hi,
after updating my macbook pro to leopard after a few minutes the fan runs continuously. I think the problem is the bluetooth process, which consumes 56 % of the cpu. The bluetooth firmeware is 2.1.0f17. I have installed the latest updates 10.5.3.
Can anybody help?
Thank you.
Susanne

Welcome to the Forums!
Assuming you're using Activity Monitor to identify the offending process, you can quit the process from there. Does it return after a reboot?
Hope this helps...
