and the last message with attached picture.
Somebody have used 100ohm resistors instead the jumper.
Here is another thread about the same problem:

Re: HP Vectra VL400 PC - Power Supply fan error
I am having the same issue and I have followed the instruction as provided in this thread....must say thanks for the info!!But I do have some questions - how does this circuit work and why by just bridging two pin does it "fool" the bios post and also does this cicuit keep checking for the fan (RPM????) when the PC is running? Also as this is a hack will it cause damage to the board? I am interested as I intented to run this PC 24/7 as a firewall.
Thanks heaps
Peter

Re: HP Vectra VL400 PC - Power Supply fan error
My HP didn't require that. I just left the fan sensor disconnected. There is a shut off within the PS, so there shouldn't really be a monitor within the MOB logic. Must be for warranty purposes.
So if you do bypass this logic, I would not worry about it. The new PS will shut down if overheated or overloaded.
If you have the old PS, you might wish to check the load with a VOM and verify the 100 ohm amount. If you do not have the old PS or it is non functional, I would try the links suggestion.
either way, please post your findings and results here.

Re: HP Vectra VL400 PC - Power Supply fan error
I have also used a 100ohm resister to jump the pins for the PS Fan and it has worked without issue!!
(I created a small PCB to make it neater!!)
Thanks for the great advise......
