From what i know, the controller just keeps an eye on the front fans-regulator ( over-voltage indicator is adjusted trough I2C bus when needed ).
The fan-regulator on the back, only takes care that the left fan runs at slower speed ( between 2,7V and 5,5V ).
Here the schematics of the board. Important info in the middle.

Thanks! I get it. If the temp is low the fan is controlled by a fixed low speed and if the temp gets high it is controlled by the SMP. Without the board it is always controlled by the SMP. So the board would normally set the fan speeds to steady lower speed.
I think we can make these boards! Another solution would be to set the RGB driver fan to steady low speed and have some tempsensor make an audible warning signal.

We could make the boards, but where would you plug it in?? Id have to swap out my whole main board from my 909 to my CineMAX to get all those extra connectors, that just plain dont exsist on the board in there now.

On the rear the board is connected to the normal fan connector and the fan is connected to the other side. All the other connectors are not used there.

Haha,
Now I can understand why I have a rectangular hole drilled into my chassis... 
And also Why I just found a black rectangular paper frame laying inside the projector... 
they are definitely brothers, probably blending twins. Anyway my switcher is different and looks like Case's.
How many hours on your counter Redfox ?
...anyway... my is still not working...

going deeply into the chassis I just discovered it has a female power cable (back left part of the chassis). I guess it has been used to power up a second device close to the projector. Redfox's and Case's Cinemax seem modded by the same person.

Hi K-L-O I also have a female power cable. I think it is used for the scaler that the seller used. I must say he splitted the mains cable on the right place before the filter and in my case it was done neatly and if I ever buy a scaler I might use it so I leave it there. In my case there is also a hdmi fitted to the rear and it is done very nice.
I know that when i just had my Cine max I had strange problems but that was because I used a hdmi input that was not perfect but worked in the end. It was a modified external moome. But once I knew I had to be patient and boot my source after the Max had booted it all turned out fine.
I am certain we will find your problem but do you have spares? A switcher from a 1209s could be fine just check the numbers and post.
This is how the scaler was fitted.

With mods, who knows what has been done to the set from a video point. As I mentioned before, I can repair and troubleshoot the two main video boards, connected with three white cables. Very few people on any forum have experience repairing these, I've done a bunch. Let me know if you want to send them in.

My fan controller in the rear is different to that one in the front too.

How many sets of yellow wires are going to your neck boards?
Pull the H board out and take a pic of that too.

Someone on another phorum saw that my switcher is probable a 1209s and yours are 909 with the 909 the cable Casey shows has to be there and it is not on KLO's max. So I say either get a 808 switcher that are nearly free or fix the cable jumper!
On the other hand my original 909 board does not have the jumper either. I just checked.

I have not checked that yet but I have just read the documentation on the AD7416 that is on the fan control board and it has a default value of 85 degrees celsius. When that temp is reached the board will take the fans out of the low voltage mode.
I guess that in the front tray that value is programmed by the controller. Therefore it might very well be that in the frontray with the wrong software the default value is set to 0 degrees or something. So I understand your observation that we need the right software in the controller to operate the fanboard in the front tray. As a trick we might try to detach the controller cable in the front tray and see if it default to the 85 degrees value 
Now all we need is boards and we might not need the software.

The software is a critical part, with my 909 software it was missing a heap of options, and the fans always ran full speed.
When i hit it with the 2.21 Cine 9 software, the fans run slower even without the extra little board in the tray. Both my controllers now have 2.21, the 909 was originally 3.12, but that is a 909 version, menus were all different, no user friendlyness etc...

What options where missing with the 909 software? Important ones? I might exchange my Cine max controller with a Seos controller to make it work in a split pack housing but if important options are missing I might regret that?

This is how we could make a simple safety fan controller.
At 80 degrees it will start an extra fan. Just set another fan at a low voltage and that is a not very beautifull but pretty easy solution with few parts.

Isnt that the control method for the vertical board fan?

Nothing i think youll miss, there were a few less options for format selection, and the shortcut keys are non functional. The warning screen when entering the service menu is not present. The fans are loud as f***. The ability to name inputs was also missing.

Possible. I picked it from documentation on the chip but thinking a little longer it is as easy to take the real board schematic and build that.
Basically it is the AD chip setup in a way that it is adressable and it takes the power from the Fan supply with a zener diode.
Then there is some stuff around the OT switch of the chip that is basically a mosfet that can pass the current and some transistors that can be pulled to get a low voltage.
The only thing is to make the print board. Perhaps it could be simple wired on a testboard.

Anyone ever flushed a BR909 controller with the Cine9 firmware ?

Case,
can the Cine9 Firmware be read out with the Barco Software (RS-232) ?
And then just flush the BR909 controller ?

I would be interested in a step by step way to flash the firmware too. I have a program Barco explorer 1.2 but it needs a pc with a serial com port I think. I do not know if those still exist?
