[REQUEST] Bios Mod for Lenovo AiO B40-30
#1
Hi all,

I had to remove CPU fan from my Lenovo B40-30 AiO (desktop) because of the unbearable noise. Confused
It works very well without it since a few months (I have removed the back cover and checked CPU max temperature which is OK)...but every time I start my PC, I have to press F2 key to confirm that I want to boot even if my CPU fan is not present.

As I often need to start my PC remotely using WOL, it can't be done anymore and stop at boot without going to Windows (unless someone press F2 key for me at home).

AFAIK, my official bios does not allow to continue anymway without fan and there is no "ignore fan error" option.

So, here's my bios backup, I've tried to find this fan or thermal control option with AMIBCP 4.53 but I don't really know what to do or which parameter I should change.

Thanks in advance,
Regards,

Don't you ever think replace a new fan??
When this message show it mean fan was broken ,so it bring noise.
You could try insert other fan to test.

Hi @genius239,

Thanks a lot for your reply but I don't really want to replace with a new fan.
First, because my PC works flawlessly without it (core i3-4160T) since a few months, summer season included.
But also because I would like to avoid unnecessary fan noise, even when it was new my (cheap) AiO PC makes too much noise for me.
I'm aware that it's not recommended to work without CPU fan but passive cooling using only heat sink without back cover works great, I'm only doing Internet and office things.
Regards
