So the display I am using is also a fan controller a friend of mine gave me a while back. It is a Scythe KAZE MASTER ACE 3.5" Bay Fan Controller. I simply disassembled the whole thing and carefully broke a piece off so that I knocked off 3" of metal so I am left with approx .5" of hardware to realistically fit in the PS3...I will post pictures tomorrow.
After looking up the unit turns out that it does use the molex cable but can be powered by either 12v or 5v. Considering that it will be displaying 2 temps and regulating two fans (considering using one for the PSU) is it better to go 12v?
Also to get this fan controller to work I had to rig a regular pc fan connector in place of the PS3 fan connector. By doing this I no longer have PWM regulation and I do not have a data cable to give the rpm data which normally would be displayed next to the temperature. So I have tested this out and all works fine I just need to find a place for the display and the best alternative to power it. I am currently using a pc psu to test the efficiency of the fan controller but would rather not need an additional PSU.
