Okay so I know when the G5 first came out there was some talk about the HDD being too hot and people relocated the sensor till apple released a software update that lowered the temp threshold. Well, I have a newer dual 2.7. The HDD are way hot. After tons of reading I decided to bite the bullet and just try to relocate mine. Well apple learned we were moving the sensor because they made it SUPER difficult to get. It is barely visible about the slot A HDD on top sticking to the metal shell, right where the fan blows on it. My sensor never read more than 86.5 degrees F and the fan RPM never moved above the slow idle of 1000 RPM. Well after about 45min of using a paper clip to separate the sensor from the roof of the case I got the sensor. I pulled it out from above there and the sensor cable gave resistance. To not break the sensor I unlogged it from the cable and then looked at getting the cable to release. There was tons of slack before the cable went up above the HDDs but it seemed to loop and then come back out to plug into the sensor. Upon closer observation the sensor has a 5 wire plug, but the wire before going above the HDD is only 4 wires. So my best guess is the 5th wire is a ground wire for the sensor and that it must have been attached to a nut of screw which was keeping the wire from letting go. Now of course I only found this out after yanking on the connector real hard, hard enough to strip it from the wires. So i know have a G5 that doesn't have a hooked up drive bay sensor. What I am asking for is a wiring diagram and or pictures real close up of how the wires hook up to the sensor. Are they in order, do they cross over each other, is the 5th really a separate ground wire. The wire is super small and i don't think i can solder it, but I can figure something out, I already removed the metal clips from the connector, so i can use the plastic connector to insulate the wires from each other. I have no way to know which side is which, as its just a black wire. Anyways, I'm kinda bummed, as now without a sensor the fan spins at 1000 RPM, which is what it used to, but if the drives get too hot the fan wont know to spin up, which it never ever did, so I guess I'm just where I was. I'd love to rewire the sensor, or even "hot wire" it so the sensor thinks it is hotter then it is, Any ideas are welcome. please help, the sensor is the same as the older G5's and says Apple Computer Inc 2003 on it. Just need the wiring diagram, and any tips on dealing with the super small wires. Thanks for all the support, and I'd be happy to fix this a software way instead by editing the drive bay sensor fan controller file, I just don't know where that is. Okay, thanks again!!! -CJ P.S. Please ignore any confusing language, as this was written at 4:30am and I'm kinda bummed out.
