    Ever since i updated my laptop to windows 10, the fan has been running on full speed and i am not running anything intensive (just firefox), task manager shows some microsoft background task host and i really don't want to change back to 8.1. I wonder if any of you have that problem.

    Model: Lenovo G510
    Cpu: Intel Core I5-4200M @2.50ghz
    Graphics: Amd Radeon HD 8570M (1gb)
    Ram: 4gb DDr3

    I got a Surface Pro 3 and got the same complaint as you since upgrading to windows 10, was thinking of going back to 8.1. Then I saw your post.
    Yep the tablet gets very hot and the fan is whirring away and all I'm doing is browsing on edge.

    How long has it been since you installed windows 10? There is some extensive post processing that takes place after the upgrade that could take up to 8-12 hours depending on the system.

    When I updated one of my Lenovo's an application called Lenovo companion popped up. This creates the link for Lenovo software and driver installation. Just curious whether you installed this or not.

    The fan on desktop PC also goes at 100% during idle time. It's ridiculous.

    Well i am putting my computer at power saving mode and the fan is all normal but still its quite an inconvenience cause that means i can't do emulation like i normally do. Plus have you guys checked the temperature of the cpu, i use open hardware monitor and it showed my cpu temp around 85C but ever since i put it on power saving it went down to 64C. I wish i did that earlier cause it was running that way for the entire day. well i hope my laptop's fine

    Hello.
    Same problem here on my HP Pavillion laptop since I installed Windows 10.
    I tried updating all the drivers without luck.
    Just waiting for a solution.....

    well i think i have discovered the root cause of this its the runtime broker application. Whenever your fan speeds up just go to task manager and end the process, i know its inconvenient but what to do, lets hope microsoft fixes this soon

    Same happened with me and my Samsung laptop. A quick fix is to go to your system settings and turn your battery saver on. It'll dim your screen and hit your performance settings but if you're mainly just browsing it couldn't hurt. The second you flip the switch you should hear your fan start to ease up. Hope this helps.

    No problems with my Lenovo Y50-70 2015 model (I7-4720HQ, GTX 960M, 8 GB RAM). I do have a strange problem that the start menu and some other taskbar apps don't work once in a while. A reboot helps but it's so annoying.

    Mine is doing this today too. I installed Windows 10 yesterday. It ran OK yesterday, then this morning the fan won't stop. It is ridiculous. I have a Alienware Desktop. Ran fine on Win 7, ran fine yesterday on Windows 10, today the fan will not stop. There are lots of complaints about this, I really hope this is fixed soon.

    UPDATE: Well after several days of this it has finally stopped maybe it was just post processing.

    I've turned on High Performance from the Power Options control panel and it turned my fan to quiet. Even my battery is somewhat better.

    Same problem with my HP Elitebook but searching around my laptop I found that the WMI provider host for all network related activity was constantly draining 30-50% of processor power. Looking around a bit further I noticed that the culprit was the HP network app, and after shutting that one down my problem was 100% fixed. Worked for my HP but I guess problem could be similar for other systems.

    There seem to be a few culprits for this issue, on a few Surface Pro 3's (But also on some others it is "Runtime Broker", the thing to do is to open task manager and have a look, if you see Runtime Broker using 10% or more CPU try shutting down the process, if the device responds to this, try turning off what appears to make it go into overdrive.

    Go settings/system/notifications and actions and turn off "Show me tips about Windows".

    This simple action sorted the issue out on my Surface Pro 3, my wife's Surface Pro and a few other machines that have responded on a couple of other posts regarding overheating.

    Given it is such an easy thing to try, what have you got to lose, but no promises because other factors could be causing the issue for you, but it certainly worked for me.

    the fan is controlled by the BIOS, but the BIOS is corrupted by windows 10
    after i upgraded it has set the password in to my BIOS which i dont know why!
    Windows does not accept that, but truly it has corrupted the BIOS with the paswort wich i have never set.
    so the fan runs at full speed all the time, and any thing else will go wrong as you can not control it anymore.
    anyway it is a good thing as long as the Windows 10 does not stop the fan from runing and burn my CPU

    Literally just figured this out. I have a Samsung Ativ Book 9 (i7), and since the update with Cortana, the fan has been revving up and down constantly - every second it goes from 50% to 100% fan speed when usually the fan doesn't come on at all, and if it does it comes on at about 30% speed for two or three seconds and turns off... Anyways, uninstalled just about everything because it was driving me mad, and disabled literally everything I can think of, still did it from the moment I turned the computer on and even before I signed in. Found the culprit:

    CORTANA. And it didn't work just to turn her off in the settings... Because she was still running under task manager, what I did was fiddle with the security settings to take ownership and set permissions to modify files under Cortana's file location, and I renamed the 'core' dll so that it wouldn't function. As soon as I did that, fan turned off, and after I restarted it now works as before.

    I'm extremely relieved. Hope this helps people reading this too, because I haven't seen any proper write ups on this save for one other person on another forum which gave me the idea.

    Thanks. So what is the dll file name, and where is it exactly?
