Hi Oli,

im wonder if they really disable this function. But what i also think about, sometimes this little "trick" works. Connect the Katana 3 Fan to CPU Fan connector and reset the Bios.

but lets see what we can get.

Cheers Chris

First of all - thank you for keep writing suggestions!

Oli:
Your right regarding the mainboard. I came to the same conclusion. And HP and ASUS writes that you should use the HP BIOS software. And I have the latest version.
I do not have the guts to do different.

I'll have a look at the chassic fan.

sumo:
I'll have an extra look at the BIOS.
Btw it's an old style BIOS. No drop-down.

I'll be back.

If there is no jumpder for bios reset, then simply remove the batery of your mainboard for arroung 10-20 min. Thats is in effect the same like a normal bios reset.

I switched the connectors, and it worked.
Now I can start my machine.

That leaved me with the challenge - when CPU gets hot it will start the chassis fan.
It use SpeedFan for this purpose.

So problem partly solved. Not the best solution, but for now it works.
