Dell Laptop manual fan control, how to access special menu.

This is very useful for me as I put a m7820 inside my precision m6400.
The top recognized officially gcard is a m7740.
I had fan control through applicaiton like MSI Afterburner with m7740.
I lost it with m7820 as well as the DELL boot screen, however with this special menu PROBLEM SOLVED.

Thank you for showing this i really do appreciate it very much. And your very welcome for the tip. I want to ask another thing about this, will the fan speeds actually stay like that at all times without "randomly" trying to spin up just while completely idle doing nothing ? It's kind of hard for me to explain, this is the other reason why I gave up and couldnt bear working daily with the E6420 laptop.
Since it's impossible to disable the BIOS fan over-riding on that unless having windows 10 (which i do NOT want) -- if i used HwInfo32 like you just showed in this video, i could force it to always stay at 2500 RPM only if i set the 2 boxes below to 0 seconds and 0 milliseconds...but it randomly keeps trying to spin faster for a momment, then back down - every 5 seconds...10..30.. 1 minute - whenever -- which is cause the BIOS keeps over-riding it i guess.
This made me so fustrated and irritated i couldnt work or deal with it on a daily basis. I'm hoping that does not happen with that hidden menu to disable the BIOS control for the M6400 ?? :( I hope this made sense.

Pretty cool! Any idea if this works with an Inspiron 2200? That is my only working Dell laptop right now!

Could you please WRITE the commands to use?? I'm trying in Dell Inspiron 5570 (P75F001) the following combination: SHIFT+FN+1,5,3,2,4 (holding shift and fn like you say) but i can't understand what button press next... My native language is Spanish... i think you say FN+R but nothing happends to me.
Please, could you WRITE the commands to use??
Thanks.

[@wowitsshit9734]

Ctrl+shift+fn held 1,5,3,2,4
Release ctrl+shift+fn now
Fn+r together open menu where can set fan speeds and stuff
