Fan Warning Not Working

[hoax32]

Hi yall!!!
Im currently working on some old PC with following issue:

It's a Gigabyte 8VM533M-RZ with the latest Award Bios Version F12a.
I have the option in the Bios to enable "CPU Fan Fail Warning".
It says that it will warn me if the Fan Fails.

Well I wanted to test that but it doesn't seem to work - I disconnected the FAN but it still boots without any warnings.
I also tried to boot with a broken fan that doesn't spin, but it still booted without giving me any warning.

It's important, because im planing on putting +3GHz CPU's in it and I don't want to risk anything....

Any idea why it doesnt give me a warning?
Is it a bug?
The Fan Controller Chip on the Board is a "SIS950/ITE8705F.

Any help is greatly appreciated!!!

the fan controller is probably broke or more likely not connected really as far as control goes but id say so long as you can set a thermal shut off point or it acts on the cpus thermal shutdown point then most cpus would survive a fan fail by shutting down anyway so your sort of safe laptops fail in this way often as the fan works but the dog hair makes it ineffective hence intel and amd put a tdp and high end temp cap which the cpu shuts down at anyway. just my 2c

How about disconnecting the fan while the computer is still running?
That should sound some alarms.
