Laptops are more likely to have problems with overheating than desktop computers. This is because everything in a laptop is packed closely together, meaning that it is harder for air to circulate. Keep your laptop from getting too hot by adjusting the fan settings for your system so that your fan is running more often, even all the time. Often the default fan settings have been designed to make the laptop quieter, so adjusting your fan settings can cool your laptop but will make it noisier.Restart your laptop by clicking on the "Start" button and then "Restart" in the Start menu.Press the "F10" key on your keyboard while the computer is restarting to open the BIOS (Basic Input/Output System) interface.Find where the "Fan Settings" section is located. Change which option is highlighted using the arrow keys on your keyboard, and press the "Enter" key to choose that option. Exactly where the fan settings are located varies depending on your computer, but it will be under either "CPU," "Advanced," or "Overclocking."

Find one of these and press the "Enter" key to look for the fan settings. If you wish to go back to the previous screen, select the "Go Back" option and press "Enter."Select "Fan Settings" and press "Enter" to see the fan settings. This shows the "fan high temp." and "fan high voltage," as well as the "fan low temp." and "fan low voltage."Change the "fan low temp." setting to a lower temperature to make the fan start working earlier. If you set this to a suitably low temperature, your laptop will always be above this temperature and so the fan will run constantly. The exact temperature needed for this to happen will vary with your laptop. 30 degrees will, in nearly all cases, be low enough.Change the "fan low voltage" setting to a higher voltage to make the fan start running at a higher voltage and therefore faster. The "fan high voltage" will be set to the fan's maximum voltage setting, so do not set it any higher than that voltage or you will risk breaking the fan.Select "Save Settings and Exit" and then press "Enter" to go back to the main BIOS page.

Select "Exit" and press "Enter" to leave the BIOS page and let your laptop restart. how much should ac coil cleaning costYour fan will now work according to the new settings.what is the best way to clean wood venetian blinds My MacBook (non-pro) Aluminum is a few years old. air duct cleaning deals atlantaLately I experience the problem that my fans are running high even with moderate usage and the body really heatens up.duct cleaning machine price It did this before, but only under heavy load (videos, flash or compiling of source files). best vacuum cleaner long hose

Now it seems like a regular thing. I also have the comparison to another MacBook Pro, which is definitely not showing this behaviour, so I am quite sure that I am not imagining things.best vacuum cleaners in new zealand Also one night when I closed the lid of my macbook, fans would not stop running (it seems it did not go to sleep mode). Any Ideas what might be the reason? The only thing I can imagine is actually to open up the body and remove the dust from there with a spray duster. You should first determine if your computer is actually working harder due to some process(es) using a lot of CPU when they historically have not. Open the Activity Monitor app and check your CPU idle percentage. If your system is using a lot of CPU, the higher fan speed is likely justified. If you are consistently showing >90% idle, while your fans are racing, you likely have a 'mechanical' heat issue (such as dust/grime on heat sinks or some air blockage.)

If it IS a dust issue, I'd expect you would have noticed the fan gradually increasing its 'unloaded system' speed over time. There are also products that will let you monitor various sensors in your computer. Some will also let you control your minimum fan speed. My favorite is iStat Menus which has lots of options for what you want to watch and how you want to see it. It looks you have to clean the dust inside. This was the problem I had some time ago. Can recommend using free Macs Fan Control app to monitor fans speed, temperature sensors and to adjust fans speed. An SMC reboot will do the trick. I had the same problem after upgrading to Mavericks with my 2012 MBA.....here is a link to how to do it. We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed. So I have been having this problem for the last couple of weeks .

I finally fixed the problem and it was so weird I just had to post how I did it for you guys. I tried all the regular things every forum tells you to do such as: Reset SMC, Reset PRAM, Ran Diagnostics, Cleaned the fans and heat sinks, Changed power cords ... nothing worked. I downloaded iStat Menus I saw that CPU PECI Die was running at 300 degrees Then I noticed my CPU usage bar would just to 101% and every time that happened a process called CUPSD was activating. So I googled CUPSD and found out that its a wireless printing protocol. So I went into System Preferences / Printers and deleted all the printers I added the printer I use regularly again And VOILA, The temp on the PECI die went down to 91 degrees and the process stopped happening. Weird but it worked! Same problem - my finding was a small cotton ball of fiber stuck at the vent of the fan. I obviously had to open the back of the laptop, but it was pretty easy if you have the right screwdriver heads.

I tried Activity Monitor and couldn't find a culprit there. I didn't think my fan was getting dirty, but only did it in the end because I ran out of other options. found the problem :) I had a similar problem with the fan running at high speed all the time. I opened up Activity Monitor and discovered that the "Dashboard" app was taking up some 60%+ of CPU. I deleted all the windows in the Dashboard and the problem was solved. So clearly I and perhaps others need to be judicious in their use of Dashboard Apps. May solve other people's problems also. I had the same problem where my fan was running on high virtually the entire time I was using my Macbook Pro (mid-2014), and found this site. After looking at the posts here I decided to check the Activity Monitor, and for me, it wound up being Google Chrome. The Chrome Helper processes were many, and multiple instances running at the same time. After trying (unsuccessfully) to stop each process (they would come right back each closure), I closed Google Chrome completely and the fan stopped running.

Using Safari only, I am not experiencing this problem (so far), and the computer is running much cooler. It looks as if I'll stick with Safari exclusively as my browser. I can't thank you enough for the info here. I hope this contribution helps others also. On My MacBook Air, my fan was running like hair dryer. Checked up Activity Monitor window and saw that a HP printer process was running with 300% CPU utilisation. Realised that, half an hour back, i sent a print command to a HP Inket Jet printer (but had not connected the printer yet on USB). Instead of killing the process, I connected the Printer. After the printout was over, I could see on the Activity monitor, that in around 30 seconds, the CPU was back to normal. Not sure, it is HP Driver issue or not? If there is something spooled for printout and the printer is not connected, it must be the bad driver that still tries to use CPU to find out the PRINTER for end less time. Ok, I had the same issue suddenly and I was going crazy.

What fixed it for me. 1. Opened the back case while MBP was running. 2. Blew on my high speed fan (due to my blow it stopped and started again) ha, then within milliseconds to seconds it came back to life - normal fan speed. So my verdict, the fan controller app might have "stuck" so it needs a "manual" reset. Once again, just blow the fan while powered on. I would definitely open activity monitor (Cmd+Space then search Activity Monitor) and go to CPU, then look at what is using the most. Mine was Microsoft Outlook using approximately 250% of CPU. Closed it, fan immediately turned off. If it is a program you use all the time, try finding an alternative and see if it works better. I wanted to say that this discussion saved my life. I've already tried to do PRAM and SMC reset with no success. After reading the postings I identified my HP printer was taking 388% of my CPU. Then I've searched on how to shut it down (it was not working on the activity monitor) and found this post:

After doing that my CPU went back to normal. My Apple MacBook Pro, my fan would not stop running and the battery was running out very quick. I spoke to the Apple Technicians who could not sort out the problem. Checked up Activity Monitor window and saw that a HP printer process was running with 340% CPU utilisation. I went to System Preferences - Printers and Scanners and realised that there were 3 printers connected to it. Once I deleted the redundant printers, the process stopped running and the fans stopped running. Thank you to this Google search! Same problem here, on a 2009 MacBook Pro 17" - fans running insanely fast and the underside was too hot to have on my lap. The battery is 7 years old and ready for a replacement soon, so I thought it might be related. Otherwise the machine is still fantastic. Checked Activity Monitor and the Finder CPU usage was always maxed out, never below 98% whenever I had a window open. More windows just crippled the running speed of the machine.
