    Intel little valley was running for me @ 65c under full load with no problems... it seems like a much more viable solution

    Yes, lower power consumption lower heat generation.
    These are great things to consider and useful, but the original poster is concerned about operation in a car that is already HOT.

    The answer is reduce the temp in the parked car. Like txspazz suggests, keep the car cooler.

    Yes, you should search... and Yes, It has been covered before!

    my point was really that the little valley runs pretty hot in the scheme of things (at least in my really small itx case... about 150 degrees hence maybe he could use that particular board or a board similar that can work up to a temp of 85 celcius

    You can do a volt mod on the little valley board to drop the cpu voltage a little and reduce temps a bit more. I did the mod on mine and dropped load temps by around 7c. Dropped the voltage from 1.35v to 1.14v.

    I just share the problem: I believe my last HDD was toasted by high summer in-car temperatures, and unfortunately I replaced it with an identical drive because I had it on hand. AMD Duron: rated 85C, M2-ATX: 85C, WD400BB HDD: 55C!
    I remember last summer the case temperatures were in the low 60's at times, at least one time it was 69C in the case. It's a slim (read: cramped, poorly ventilated) case and of course the M2-ATX doesn't have/need a fan, leaving only the CPU fan swirling air inside the hot case inside the hot trunk. I went and got a an 80mm case fan, but it's not very powerful and there's not many useful places to put it in the cramped case. I might go shopping for a smaller one or get creative with that case and the power drill...

    I have the Travla C-150 case and it has **** poor ventilation by default. What I did was near the top (also front) is cut out 2 x 60mm fan holes and mount a couple high speed 60mm slimline fans. Works perfect and they move a ton of air through that little case. It's a bit on the loud side, but since it's in the trunk you can barely hear it in the cabin.

    Going H2O isn't a LOT of money, is far more efficient, and just plan looks cool!
    Water cooling is great, makes for a nice, quiet, cool desktop PC. In fact, my desktop is water cooled, and is so quiet, the loudest thing on it is the hard drive....

    For a carPC, it's rather risky, and really unneeded.

    Why would I say risky? Well, whats the biggest problem with a water cooled PC? Leaks. Yes, leaks. In a desktop PC, you can use good barbed connectors, and nice, tight clamps, and not have to worry about leaks. In a carPC, you can use these same things. However, the constant vibration will eventually cause something to get a bit loose, and then you have your leak, and a short, and then quite possibly a nice little electrical fire.

    Un-needed, because you can make a nice powerful carPC using low heat components. use a mobile processor (I use a Core Duo, there are even better nowadays), and use a midgrade graphics card that doesn't put out a lot of heat, and you will have more processing power than you will ever use in a carPC.

    But hey, if you want to get all complex and run water tubes all around, and all that, to solve a problem that does not exist, have fun.

    How about having a switch so that the PC doesn't turn on the ignition and then when the car is cooler (from AC or moving), just turn it on with the switch.

    Someone suggested measuring its current temp, I'd agree with that. See where your at right now before choosing a path...

    No solution is really going to get cooler than the ambient temp around the PC enclosure.

    Right now it sounds like the ambient temperature in the vehicle is the primary issue. As such I would perhaps suggest one of the solar powered ventilation fans that I've seen around (JC Whitney perhaps) that you stick the solar panel on your dash and it powers a small fan, enough to ventilate the interior and keep the car from getting stupid hot.

    As some else said you could also install Peltier coolers (on chip/die) that were watercooled to see more immediate results. Peltiers get cold/hot in a matter of seconds. However if the ambient temp in the vehicle is still beyond what the PSU will operate at modifying chipset/die/cpu cooling is a moot point.
