HP Recommended
Product: Z4

Hello,

I added a different graphics card in an Z4 workstation and now on every boot I get the error: „513-Configuration requires a Front Chassis fan and this fan is not detected.“

This unit does not have a front fan and now I always have to skip/confirm this error with the keyboard.

Some posts suggested that in the BIOS there is a setting that ignores such post errors, but it seems there is not. At least I cannot find it.

 

I also read that those are standard PWM fans and I have some non-HP 80 and 120 fans, so I tried to connect them to the front fan header, however it seems even though the header on the mainboard has 4-pins it is not a standard PWM Header. It is missing the cutouts for the two notches.

 

Anyone know a) how I can disable this post error or b) if I can just connect my standard PWM fans by plugging it in by force and it will work? I can also remove the notches from my PWM fans..
