temperature controlled power with a epia tc

Ok, so I have an epic tc from a previous project that I was trying to recycle into my new car pc. However, I want to put this computer into a small enclosure in the car, and so I am worried about temperature. Only a few of the car pc power supplies/power controllers seem to have temperature sensors on them, so I am not sure how to proceed. I see two options that I have.

1. Keep the TC and try to figure out some way to control it with some combination of dc-dc converter such as the CarNetix CNX-P1290 with the Micro Shutdown Controller in line with it. This way the shutdown controller which has temperature sensing controls the power, and the carnetix filters the power to the tc. My problem is that I think there might be some problems wih the micro shutdown controller being in control of the pc, since the carnetix also has a shutdown controller.

2. Spend a lot more money and buy a new motherboard that has a normal ATX power supply and then connect something like the dsatx to provide all of the power filtering, control and temperature sensing for the whole pc. This seems like the simpler solution, but I don't really want to spend the money if I don't have to.

What do people think, will having the carnetix in line with a micro shutdown controller work, or is this a recipie for disaster? Thanks in advance.

does anyone know?

use CARNETIX 12VDC-DC. works perfect, it has metal enclosure w/fan, and temperature controller. Carputer easily survives cranking.

I didn't see anything in the product description that says that it has any kind of temperature control, where did you find this out? Is it on the CNX-P1290 model?

I have one, I actually disassembled the case, and saw the sensor. Anyway, if it gets overloaded, it will shut down. I have 60W model, and so far I had no problem with it. I keep the PS right under mu HU, it warms up, but no more than 100 deg typically.

Good to know that the carnetix will protect itself, but I was looking for something with slightly different thermal protection. I want something that will prevent the computer from even starting up if it is say below freezing, or above 100 deg. That way I won't damage the hard drive, or overcook the processor. Not sure if that is needed, but I am a little weary of having the computer try to boot up in -20 deg weather.
