512 - rear chassis fan not detected

[megurrola]

Hey John,

I've the same problem that yo had:  moving my Kaili2 mobo to a new chassis with a low speed chassis fan caused that boot message to appear.

Tried speedfan but I'm unable to locate where in the program is located the option to increase the fan speed.

I'm using this speedfan, BTW:  http://www.almico.com/sfdownload.php Just in case you're using a different one.

Any advice would be greatly appreciated.

Thanks

John, first I noted you have been back (July 2019).

This person wants to know how you tuned "speedfan" to solve the problem.  I realize its an old 2018 message, but the OP dredged it up. I separated/sliced it off to create a new and more meaningful inquiry.

@Wb2001 Thanks for the link to the article about speedfan.

Managed to increase the fan speed following that, but after power off/power on, the BIOS message 'fan not detected' keeps showing.

Supposedly @John-Konstantin managed to make that message disappear with speedfan, but what I see ,is that after rebooting the PC, the fan speed slows again, thus making the message appear.

Of course you can make speedfan start at Windows startup, and set the fan speed to a higher speed, but I don't see the way to make that change to persist at PC boot time, when the BIOS starts.
