Why my fan runs continuously at a high rate

• Fan runs continuously at a higher speed

  I have a HP laptop. This problem started a little over a month ago: the fan started to run constantly at high speed and I was afraid that my LT was overheating so I went online to find solutions and the offered was "cleaning". I blow the air frequently, because I have a dog. So without taking it apart, I think it's relatively clean.

  After 'cleaning' didn't solve the problem, I have blocked some programs (many) start with the startup of the computer. That worked wonders. Not only the fan seems to 'calm down', but picked up speed and freezing (flash plugin AHHHHH drive) until reduced to a minimum.

  Now, he resumed running continuously and at high speed. I went to check and make sure that the start menu had not changed. It seems still good. When I run the Task Manager, it will display an application that is running, but 20 to 30 processes and services from 50 to 60. I have maturities adjust this number if I knew which ones it was safe to stop. I tried Googling some of them, but could not understand what is needed and what is sure to stop and exactly how to do it.

  Any thoughts?

  Rather than guess about potential overheating, download a program to monitor material as one of the following conditions:

  SpeedFan

  HWMonitor

  Core Temp

  As much as that processes and services 'need' to be executed, you essentially already do the correct thing - searches on the names online.  If there are specific processes or services that you wish to get more information, provide the names and maybe someone here will have some tips (without guarantee).

  You can also right click on one during the process in the Manager of tasks and select Properties.  The location of the file (under the general tab) and information on the Details tab can provide clues about what made the process.

  Hello

  Since new my laptop fan is running as soon as it is turned on, battery or sector makes no difference and is noisy. I tried the power settings for the Middle mode or silent mode which makes it much better, but the machine turns off after a while which is irritating to say the least.
  I had messages on battery bad installed, but healed with auditor of battery and the update of the Bios updated.

  Someone has ideas about how to stop the fan and continue to use the laptop without crashing or is - it just the processor runs hot and must constantly the fan to operate?

  Makes no difference how many programs are running either.

  Hello

  The processor produces a lot of heat and the use of the fan is very important.
  From time to time, it is important to clean the cooling modules and fans, because dust and debris. Dust and debris could have a bad influence on the circulation of air.
  This is why the unit will stop automatically to prevent damage.

  I think you should check the cooling modules and clean carefully.
  But generally, there are not a lot to do. The fan should run to cool the devices inside the laptop.

• The fan runs continuously

  I had this problem for a few weeks and I don't know why. The fan on my Dell laptop starts to run as soon as I turn it on and it does not stop. My son cleaned it out to ensure that it is not full of dust, but that has not changed anything. the computer will not even hot and the fan is running. I can't imagine it's good for the life of my computer to have that going on - is this a big deal?

  Actaully, it is quite normal to have your CPU fan runs whenever your PC is on. He does not even use a lot of battery, so you shouldn't worry.

• Fan runs continuously when open the mail

  I have a new 15 "MacBook Pro retina, I have Aproblem with the fans running constantly. This only seems to happen when the mail is opened. If leaving the app e-mail the fan speed reduces and stops. When I open the application mail in seconds the fan starts to accelerate and run. Close the application and the fan stops. This does not happen with any other open app. All of the suggestions. I have already reset the SMC and LANDAU.

• HP Pavilion g7-2240us Notebook: fan run continuously?

  I took my laptop yesterday after he had the replacement hard drive.  I've been setting up since and I noticed that the fan turns off ever.  I don't remember what is the case of the previous two years.         Is it OK?  Here is a way disable manually?   What should I do?

  It should run all the time to avoid the accumulation of heat, but not 100%.  Change your profile settings to yield power or Power saver.

• ProBook 6545b: ProBook 6545b fan runs continuously on the average speed.

  The fan on my HP ProBook 6545b worked at all average speed for the past 6 or 7 hours I had it lit.

  I looked at performance monitor and the CPU is a little more than 50%, most of the time.

  I checked the process in the Task Manager tab and see nothing unusual.

  Any ideas what the cause, other than dust in the fan?

  Thank you.

• the fan runs full speed at the beginning upward

  HP Pavilion p6-2037cb bought 19/01/12.  Windows 7.  There is no error message.

  When I turn on the computer after it has stopped all night the fan running at full speed.  This has happened several times in the first month.  The first time, he stopped himself after a few minutes.  Then I learned to stop it by restarting the computer simply.  It still works, but what was once happen one or two times a month, happened twice in two days then you worry I the problem worsens.

  It never happens when I use the computer because I don't do anything that requires a lot of cpu or causes a warm-up.  I just surf the web and send e-mail.  No games or videos or TV.

  If it's a problem of connection fan I would like to know the nearest repair service.  I would rather that ship it.  But I can't find a list of authorized warranty repair service center.  I followed the links on HP Support Assistant but got sent to a site that does not list the pavilions.

  I need to know why the fan runs full speed at first upward and where to repair close to where I live.

• Battery Tecra M11-130 with not power and the fan runs constantly

  We are having a problem with the battery on one of our laptops. When left for an hour or two the laptop turns off because the battery is dead. We have mounted a battery new but still only get about 1.5 hours.
  In addition, the fan runs continuously. I looked at the PC Healthcheck software which shows as follows:
  * Power *.
  Other costs 14%
  40% of energy consumption system
  Good battery
  * Temperature and fan *.
  CPU temperature 67%
  System internal temperature 56%
  88% fan speed

  I would like suggestions.

  > We have mounted a battery new but still only get about 1.5 hours.

  1.5 hours is a common value, you should consider that dough working time depends on its portable use.

  Battery needed to dump a lot faster if the CPU would be stressed out a lot in your case, that something could run in the background, lose power CPU performance and the dough.

  In addition, you said that the fan runs constantly this could discharge the battery too.
  Therefore, it would be interesting to know what process emphasizes the central unit.

  Start the Task Manager and check the processes tab. In the CPU column, you can find the process that emphasizes the central unit.

  In addition, to change the settings for the CPU performance and cooling of the activities in the options of Win 7 powers that would help to increase the performance of the battery.

• Satellite Pro A120 - cooling fan runs constantly

  Hello

  Bought a satellite pro A120 "Intel centrino duo" in January and for the last two weeks, the fan runs continuously. Even when the cold portable OS, it runs complete but even just word processing or done yesterday it runs very hot. I need to access the fan to have a look for dust etc but I couldn't for access!

  If anyone knows how that would be great. Either that or somebody can suggest any way to stop the laptop gets so hot. I tried on mode low power - without change, and it also works on different surfaces, but no change.

  Any help much appreciated. Thank you

  Hello Dougie

  In my opinion you should not do much and check anything because your laptop is new and under warranty. If something is suspicious to you, please contact your dealer local or much better is to contact directly the authorized services.

  Explain the situation and let it check your laptop.

• Why the fan on my macbook pro continue to run at a fast pace for long periods?

  The MacBook Pro mid-2010

  OS X El Capitan, 10.11.3 version

  Processor: 2.4 GHz Intel Core 2 duo

  Memory: 4 GB 1067 MHz DDR3

  Graphics card: NVIDIA GeForce 320 M 256 MB

  163 GB available

  iWorks ' 09 has been upgraded to the latest versions

  No new upgrade is available for the system.

  My Question: Why the fan on my macbook pro continues to run at a fast pace for long periods?

  I guess that the fan runs constantly, because the CPU is working at a high rate. I rebooted several times but without any resolution systems. At the bottom of the computer is very hot at times so place the laptop on an object that allows good air circulation. This problem occurs intermittently every few weeks or more. I wonder if it is downloading an important upgrade, do a scan of viruses, or by working as a bot. Lights for hours. Currently, I estimate that it has worked rapidly to possible 6 hours. Thank you.

  It will usually be to dissipate internal heat from running resource intensive applications.

  Download and install a temperature/speed control application.

  Open the activity monitor all THE PROCESSES and CPU to display values between high and low.

  When the fan speeds up, post pictures of both for review.

  Also run Apple Hardware Test:

  Note that an error free AHT is inconclusive.

• Why the execution time increases with a while loop, but not with "run continuously?

  Hi all

  I have a problem of severe weather that I don't know how to fix it because I don't know exactly where it comes from.

  I order two RF switches via a data acquisition card (NI USB-6008). One job at the same time can be selected on each switch. Basically, the VI created for this feature (by a colleague) resets all the outputs of acquisition data and active then those desired. It has three entrances, two chain simp0le controls and a cluster table, that contains the list of all the outputs and some practical information to know what is connected (specific to my application).

  I use this VI in a complex application, and I have some problems with the execution time, which increased whenever I said the VI, so I did a test VI (TimeTesting.vi) to determine where the problem came. In this special VI I record the execution time in a csv file to analyze then with excel.

  After several tries, I found that if I run this criterion VI with the while loop, execution on every cycle time increases, but if I remove the while loop and use the funtionnality "Continuous run", the execution time remains the same. In my high level application, I have while loops and events, and so the runtime increases too.

  I someone could explain to me why execution time increases and how can we avoid this? I have attached my VI test and the necessary subVIs, as well as an image of a graph that shows the execution time with a while loop and «run permanently»

  Thanks a lot for your help!

  Your SetReset_DO VI creates a channel whenever it is called.  And that you never delete a task.

  When running continuously, that it's as if it only runs once and LabVIEW has internal mechanisms to close references that will not be used again.  When a VI is used as a Subvi, LV does not know if she will be called again, and lacks these things until the first level VI stops. You have a memory leak.

  Just as you open and close your file outside the loop for, create your channel out of the loop.
