  2. CPU Fan runs constantly

    Hi,

    We would like to know the following information to assist you better regarding CPU fan issue.

    • Does the fan runs constantly fast or do you hear any noise?
    • Have you tried updating all the drivers of your computer?
    • Have you tried any troubleshooting steps before posting this concern? If yes, what are those?
    • What is the memory/disk usage in task manager?

      You may check this by typing Task Manager in the search box
      and hit Enter. Check which application
      is taking more memory or disk usage.

    Looking forward to your response.

    cpu fan running

    Cpu fan not running on cold boot

    Thanks for the feedback.

    The system has four direct fans that are part of the case.

    Four fan headers on the motherboard, two are three pin, two are four pin,

    cpu 1 x 3pin, system 1 1x 3 pin, system 2 1 x 4 pin, power 1 x 4 pin.

    Cpu water pump is connected on cpu header, cpu fans (2) are connected to system 1 header ,other fan is connected to system fan 2 header, nothing is connected to the power header.

    1300 w psu, system is under one year old.

    The cpu fan has a fan curve of + 25 % in bios.

    The fan has never been set to run in pmw or manual.

    Environment ambient temperature is on average 50 to 70 f

    When the cpu fans do not run it shows in the bios as such.

    Basic io points to a faulty temp sensor on the main board or

    temp not high enough to kick the fans on?

    Update; cold booted the system, fans run then stop, core temp is under 9 degrees celsius in the bios.

    As soon as the cores hit the 9 degrees celsius mark, both fans run normally.

    This was not going on until the january 2016 updates and I believe it is windows power management that is causing this issue.

    Using a uefi bios that supports win8 as natively but set hat to other os s because I did not know if setting that would be good or bad for the os, hardware, drivers or software.

    Still need so help on this.

    Update two.

    Bios settings for the cpu is clocked at 4.0 ghz.

    According to task manager and speccy the cpu is clocking up to 4.7 ghz ( turbo boost).

    When cold booting and going into the bios and change anything or just exit out, I receive

    a bios warning message about the system not able to boot.

    Options are load default options, load optimized options, enter bios; select enter bios, save and exit and pc boots fine.

    The os is very stable at this point and can not figure why the bios boot strap is having so many issues detecting and keeping the settings but once the handoff is made it is fine.
