@campbell87 said in Superpi case - shutdown script not working.:

the only difference on this case, is that the pi is powered by the case, so my power cable goes direct into the case, and not the pi.

Sorry did not get this.... The old case was not directly wired, so there was no plug to put on the GPIO header of the Pie?
Can you send a picture of the old case please?

Your description of the new housing is the usual wiring. But nice you get it working now :-D
Which script did you use now? If you use the crcerror script then you can terminate any running emulator by pressing reset button.

@Swedishkiller12 Undervolting a 12V fan on the Pis 5V or even 3.3V pin is not going to give you any benefit. In fact it most likely is going to move a lower volume of air then your 5V fan on the 3.3V rail.

Fan noise really comes down to two things. Air turbulence (fan speed/fin design) and ball bearing quality/noise.

Spinning your fan slower and having an adequate passive cooler on the SOC is likely your best bet.

Have you measured/logged temperatures while under load? If you can do this while running on the 3.3V pin and are staying below the ideal max of 70C (this is not the absolute max, but rather the safe longterm max for most models) then you should be fine.

I sent an e-mail to RetroFlag the other day describing the issue and from looking at the photo of the wires I sent, they said the colored wires were in the wrong position. They apologized then gave some directions on how to take the wires out and what the proper color order is.

I tried taking them out of the black plug but it seemed a bit of a hassle. Fortunately a replacement case arrived from Amazon today and the colored wires in the replacement case are in the correct position. I rebuilt my RetroPie and the shutdown and reset worked right away :). Thanks again for the help.

tldr: Original case wires were messed up, replacement worked.

As it turns out, the board with the safe shutdown circuitry was missing a resistor near the fan header, so the path that needed to be made to induce the script was not being completed. Retroflag was kind enough to send a replacement board, and now it works perfectly. No script modifications required. See the included picture for details.alt text
