    Ok, So I have the Dell Inspiron 7570 (i7) and a great laptop it is. I only have one annoyance and that is when the laptop is plugged in, the Fan is working at 100 % and can be very noisy, when power is unplugged from laptop and it is running on batteries, fan slows down and is a quite beast again.

    I have tried a few option to resolve my Dell Laptop loud fan noise, like changing power options from Dell to Balanced, also tried various Bios updates and power options within BIOS, cleaning air vents etc. all to no real effect.

    For myself, usage of the laptop lightly,  the following option worked for myself (not for gamers and heavy usage) but for general streaming and the occasion outlook/forum work, this kept the fan under under control and CPU and GPU seemed to not lag to much.

    • Right Click BTTM right of screen Power Icon and select Power Options
    • Select Dell Power plan
    • Select  Change Plan Settings
    • Select Change Advanced Power Settings
    • Then go to Processor Power Management
    • Select  System Cooling Policy > Plugged In and change from Active to Passive.

    This has effect of slowing CPU down before it needs to increases Fan Speed.

    So, good for browsing etc. but as said above, not suitable for gaming etc. and when I do need the extra CPU processor Power over a longer period of time, I just switch back to Active


    Edit: a an update, this method for reducing fan noise seems to work well, CPU still goes to 100% when it needs to, but seems to use the CPU more gently over a slightly longer time period  to avoid generating extra heat so fan is ticking over at low revs etc.
