My 2001 MacBook Pro fans run almost constantly, while my previous 2009 MacBook Pro fans seldom ran. Why is that?


I had to chuckle, because many MBP users actively seek out applications to make the fans run more often and more vigorously. It seems that early models of MBP would quietly cook themselves to an early demise.



You should follow Ted James\' advice regardless - it\'s easy to do and worth doing whether that\'s your problem or not. However, I had a similar problem with my MBP and found that it was a browser plug-in that was the CPU and running the system hot. If it\'s a software package making your mac run hot, that\'s a little more tedious to troubleshoot, but still pretty simple. First - try this simple step: While your mac is running the fans (misbehaving) start the Activity Monitor app - which is in your Utilities folder. If you prefer to use LauchPad to start applications, then you may need to look for "other" start typing "activity" in the search box, b/c the utilities are not shown by that name in some newer OS X releases. Once Activity monitor is running, select the CPU "tab" at the top or bottom of the app. Now you should be able to see how busy your system is in a moving graphic at the bottom center of the app. If your CPU is running at nearly full capacity, have a look at the column called % CPU. If the process name a the top of the list is contributing the majority of your % CPU, then that is the candidate for an errant application overheating your Mac. I\'ve attached a screen shot of Activity Monitor working on a quite system with almost no activity.

It should be obvious, but the next thing to try is to exit or kill that application and see if that allows the fans to spin down.



Hope that helps.

Fan noisy at steady high speed


Try replacing the cpu fan. The reason why the cpu fan is noisy its because the bearings are rusty and need some lubricants. But in this case you have to replace them. For me there's no need to upgrade your bios. Its just a hardware problem.

How do i quiet this fan down? 478


What do you mean by Quiet it down? If the fan is running at an excessive speed, try to look in the Bios (Hardware monitor) settings to set the CPU fan to auto. This will provide a balance between fan speed and cooling.

If the fan itself is mechanically noisy, then you are probably looking at a shot bearing, causing it to run noisily. For the cost of a new heatsink and fan (about £20.00), its worth considering replacing it

I need a new cooling fan, how much are they?


The old addage "you get what you pay for".....It applies here. You can get 80mm to 120mm fans for under 20 bucks, but depending on how fast they have to spool up to keep the processor cool and how well their blades have been designed determines how loud they are, especially if they have been cheaply made....poor bearings and poor blade design equals noise. Bigger fans are actually a lot quieter because to move air they do not have to turn as many rpms. Get the biggest best made fan you can that will sit confortably in the case without interference. Also, download the little program called Speedfan, it will monitor fan speeds and system temps and make adjustments to the fans to keep them in the quiet range when possible.

My sony laptop computer has big noise when the fan start.


Hi there,

It is normal for the computer to do this. When an application you are running makes greater use of the CPU, memory, video card, and disk drives, power consumption increases, and the fan either kicks up in speed or turns on. If the sound is annoying, you may be able to reduce the fan cycles by cleaning the dust out of the computer case.

Get a can or two of Dust-Air or a similar product.

Open the case of your computer by removing the screws on the back. Some computer cases have easy-open latches, so you may not need tools. Use a vacuum cleaner to get the bigger dust bunnies out of the case, then use the Dust-air to blow out all of the nooks and crannies. Make sure to blow out the heat sink for the CPU; the vanes tend to clog with dust. Blow off the vanes of all the cooling fans, too. There will be one on the CPU, and probably a few others, e.g., most video cards have their own fans and heat sinks now.

Replacing the case fan with a quieter model, such as a Vantec, can also help:

Computer makers build systems with the cheapest parts they can get their hands on, and if you're handy, it's worthwhile upgrading.

Warm regards,

Assalaam-o-Alekum and Hello This is Bilal, I have Dell optiplex GX280 with 3.2Gh processor. Iam facing a problem with a cooling fan which install for cooling of processor. Thats run very fast after few...


Hi, I have the same computer, and the stock fan that's installed has a very high rpm. It is a variable fan that can actually be set in the bios to run in a quiet mode or in a mode that is more for heavy work, like your gaming, or other intensive work that requires a lot of processing. Other tasks that require the processor to work harder are graphics, CAD, audio recording, and video editing and viewing. You will notice on your dell, that you can actually hear the fan go through different speeds depending on how much work the processor is doing. It can get loud, and you may even think that maybe something is wrong with your fan, but that's just the fan attempting to cool the processor as it's working. This is software controlled based on the temperature reading of the processor chip. To use a quieter mode, you can enter your bios during startup, and find the fan settings. Change the fan setting to the quieter mode (it actually reads something like "quiet mode" or office mode" or something like that - very easy to determine. Then save your settings and exit bios. I need to tell you though, it's not much quieter. There are quieter fans you could buy for your CPU, but it may not be worth it to you. I had my cpu sitting on top of a side desk, and it was unreasonably loud. I plaecd it on the floor under the desk, and now I can barely hear it. Maybe you need to place your cpu further away from you in such a way. You can even get foam and "soundproof" your cpu, remembering of course, not to cover the ventilation holes in your case, or cover any part of the processor or motherboard - just the interior walls of the case. A lot of techs I know who need their processor near them (disk and rear panel access) use this technique. Hope this helps.

Dell XPS 210 very noisy what can I do to quiet it


Hi, The noise from any computer is due to the fan. It is really the only thing that makes noise on a computer - unless you havce a bad drive. If you can hear a drive outside of the case, then it's about to fail. You can buy a quieter fan for your laptop. That will take a bit of investigation on your part, as far as getting the dimensions and wattage of the fan from your manufacturer's web site or the instruction manual that came with your computer. You would do best to go to a reliable and competent computer shop and have a quieter fan installed, rather than doing it yourself if possible. This mod is very simple, and can make your computer run better, provided you get a better fan that can cool your machine better.

Samsung av-r610 av receiver. noisy cooling fan. can it be replaced with a quieter/more efficient one?


Hi i have same unit. If you keep the volume anywhere below 31 the fan is not intrusive (you can hear a quiet hum but not a bother) I also give it plent of ventilation ie 1 foot at back and a little less to the sides. The problem is the unit is so slim the fan has to work harder to dissipate the heat build up.

The Crucial website suggests you can put 1GB in each slot. http://www.crucial.com/uk/store/listparts.aspx?model=VAIO%20VGN-S460%20Series Sony might know which CPUs will work with this. Hopefully any Pentium-M with 533 FSB.
