Windows 10: CPU fan running at full speed in Windows 10

Hello, everyone.

I have posted this in other forums, too, in the hopes of getting some ideas.

I recently installed Windows 10 on a desktop computer and everything went as smoothly as it could have, with no problems at all. So, motivated by how well everything went with that computer, I decided to upgrade Windows on a laptop as well. The laptop is a Toshiba Satellite L855, with an Intel Core i3-2370M processor.

The upgrade process on the laptop also completed successfully. Now both computers have Windows 10 and so far it has been running... fine.

The only unusual thing I've noticed with the laptop is that the CPU fan wants to run at full speed all the time, even though the computer is never used for any "processor-intensive" tasks. The normal activity on it is browsing the web, watching videos, playing music, writing text files and really nothing more than that.

I immediately found this odd and I have come to the conclusion that something in Windows 10 is responsible because:

a) This never happened in Windows 7, which was the previous operating system the computer had, and

b) This doesn't happen when I start the computer and go into a different operating system, namely Ubuntu.

Well, thank you everybody for reading and please give some advice if you have any. Surely I'm not the only one who has run into this situation.

Anyone got any joy with Win 10 running fans at full speed?

CPU fan running at full speed in Windows 10 Solved - Windows 10 Forums

 

Fan noisy, loud and fast after installing Windows 10

I've checked the drivers and I'm using all the latest versions. The problem with manually limiting the CPU fan speed is that you risk damaging the CPU and/or motherboard if you are running processor-intensive tasks that really do need the fan to run at
full speed.

The only thing I changed to bring about this problem was to install Windows 10. I'm sure that if I went back to Windows 7 it would stop. Therefore, it is Windows 10 that is causing it. I

 

My laptop fan also seem to run more, not all the time, but more. Have not had time to research.

 

Know that:
The speed of the CPU fan is controlled not by Windows but by the controller on the motherboard and is based on the temperature of the CPU. So it would be obvious to this old tech, that your Windows 10 is running the CPU more than your previous OS. If you've been Overclocking your CPU, STOP IT!

Go into the task manager, (CTRL + ALT + DEL) and look at the CPU usage. That might give you a clue as to why the fan is running so much. There are many things that run in the background, like Services you don't need, that can be shut down to minimize CPU usage. That's one of the things I do in the first five minutes, after I install a new OS. Get rid of the redundancy and CRAP running in the background to improve system performance. Then set up Windows to use all the cores in the CPU, and modify the Registry to load the Windows Kernel into RAM memory on Boot-up.
These are all things I've been doing for about 15 years with several different versions of Windows. Works for me!

Good Luck!

One thing that seemed to ramp up the CPU use and fan is a process called Runtime Broker. Run the Task Manager and see if that's the case on your systems. With the RTM version of Windows 10, Runtime Broker doesn't seem to misbehave like it did on earlier previews, at least on my computer. But some have reported it is still causing CPU use of 20% to 40% on their systems. If it is a problem, you can disable Runtime Broker in the registry. If anyone needs the detailed instructions for doing this, I will post them here on request.

 

Also, there's now a handy Startup tab in Task Manager, so you can stop apps from running at startup.

Another potential solution to your fan problem is to stop acting as a P2P server for the rest of the world's Windows 10 installations:

• Search for “Check for updates” in the Start menu.
• Under “Windows Update” choose “Advanced options.”
• Under “Choose how updates are installed” click “Choose how updates are delivered.”
• Disable the toggle under “Updated from more than one place.”

 

The pink elephant in the room, for many of us anyway, is 'Cortana'.
I don't want it, I'll never use it, and I don't want it running in the background, but...
even after I've turned Cortana OFF, it's still loading into ram memory and taking up 33.1mb of valuable ram.
It's the second largest user of ram on my PC, With Firefox being #1.
While the Runtime Broker is only taking up 2.0 mb of ram.

My next step is to get rid of Cortana, completely, totally and 100%.......GONE!

Cheers mates!

In task manager right-click Cortana and choose 'Open file location' to find out where Cortana's folder is. Rename this folder (add .bak to the name), it will fail and show a 'try again' dialogue, end the Cortana process and quickly press the try again button before it starts up. No more Cortana.

For Firefox get the Memory Fox add on, you have to have it's green button showing but besides that it owns for freeing Firefox memory, usually takes my Firefox memory down to 3MB when idle...

 

This I want to know more about.

 

One thing that might help is adjusting how Windows 10 handles updates. Go to settings/update and recovery. Select "advanced options" Select "choose how updates are delivered." From here you can toggle the slider off, or select the local network only button.

 

Hee Hee!
I tried that, but at 72 I'm not fast enough to kill Cortana before she re-runs herself..... so.....
I Opened up that "Open File Location" and found the two files (actually folders) that Start with....
"Microsoft.Windows.Cortana" and I opened the first folder, Took Ownership of it and deleted it. *Party
NO Problemo!

Then the second folder has all the .dll files in it. So I just renamed every .dll file to .ddd.
Rebooted the PC and VOILA!...... Cortana was no longer running.

I'm pretty sure some scripting Guru will write a VBScript to do what I've just suggested.
Then we can just run the one little script, and NO MORE CORTANA.

With some experimentation, it might be found that just renaming one or two of the .dll files would do the trick.
That might even be done with a batch file.

Pause:

Well, I just fired up Laptop #3, and sure nuff, Cortana was running, as seen in Task Manager.
So I Right Clicked on Cortana and "Open File Location". Then I changed just one .dll file.....
"Cortana Core.dll" to "Cortana Core.ddd", rebooted the PC and Cortana was NOT RUNNING any longer.

Success at last!

Now it's off to bed! Y'all have a great TGIF day.

Thank you all for taking the time to reply and thank you for your ideas.

I want to say that I never meant to imply that Windows 10 had simply "decided" to increase the speed of the CPU fan. Logically, if the fan was speeding up it was because the CPU was working harder, which made its temperature go up, and it was trying to cool it down. I wanted to determine what was the cause of the increase in CPU utilization, which caused the increase in temperature, which in turn was causing the increase in fan speed, and I said it was something in Windows 10 because it didn't happen in the other operating systems I had worked with.

I did try some of the things suggested:

* I had noticed before that Cortana is always using up some memory, even though I did not enable it when I upgraded. So I did what Nus said and changed its folder name to prevent it from running.

* I changed the "Updates from more than one place" option to OFF, as suggested by PRMan.

* I even disabled the Windows Update service completely.

* I tried looking for and updated graphics driver, as was suggested in another forum, but found none.

However, none of those things was the cause of the problem. Checking the Task Manager I found two background processes called:

From Microsoft Background Task Host

and

From Microsoft Download/Upload Host

These processes are both located in the C:\Windows\System32 folder and their files are backgroundTaskHost.exe and BackgroundTransferHost.exe, respectively. At the time of writing this I have no idea what they do or what they're for.

All I know is that, normally, the CPU use in my computer is under 10% and whenever these two processes pop up, CPU use jumps to as much as 60 - 80% and remains in that range, even if I'm not doing anything else. Then, when I kill the processes, the CPU activity decreases and, naturally, the fan slows down.

So, as much as I wanted to blame Cortana, she was not the wrongdoer... These two blokes are.

In any case, does anybody know something about these two processes? How to disable them or prevent them from running, maybe? Even after I kill them, they briefly pop up in the Task Manager from time to time.

Thanks again.

 

I had the same problem with my laptop but after deleting the windows old files it some how fixed this problem just use disk clean up and use the advance settings to delete these files safely

 

I will get rid of those files
