Hi,
I'm having the exact same issue with my SH67H7 (same board as SH67H3) / i5-2500 / SSD Crucial M4.
I bought a Noctua NF-B9 and later a NF-B9 PWM when I realised that I bought the wrong fan (non-PWM) to replace the original noisy fan.
Like you, when I assembled the box, I only mounted the CPU, the RAM and the SSD to get the system working quickly.
When I remove the original fan and plug the NF-B9 PWM, the fan rotates for half a second and stops, and the system doesn't boot. If I plug both the NF-B9 and the NF-B9-PWM, the system boots but is of course noisy (the NF-B9 is at full speed as it is pluged on the 3-pin connector).
The amperages are :
- AVC fan (original) : 0.41A
- NF-B9 : 0.12A
- NF-B9-PWM : 0.08A
Then, I found and read this thread.
Like you suggested, I tried to add a HDD and a DVD drive, but the shuttle still does not boot...
I understand that the shuttle performs an amperage test at boot to ensure there is a fan connected. What I do not understand is why a HDD or a DVD drive would change the amperage on the FAN connectors, as I would plug it on normal Sata power connectors...
Could you explain your solution?
Thanks a lot !
