    Question Help...I think my CarPC is doomed....

    Ok, first I want to thank this board. It's been an awesome trip to build a car pc, but sadly, depending on what feedback I get from this I may have to remove mine. I live in the Des Moines, IA area. I've been having temperature issues recently with my system, but with temperatures climbing into the 90+ range I can't even get my system to stay running for 5 minutes. My system specs are as follows:
    • Biostar IDEQ 210M barebone Small Form Factor P4 system.
    • Pentium 4 (Socket 478) 2GHz (or 2.4...can't remember at the moment
    • 2x DDR RAM sticks (Can't remember the configuration 2x128 or 1x256, 1x128)
    • 80GB SATA hard Drive in Aluminum Removable Drive Rack (Compusa rack)
    • 2GB SanDisk UltraII CF card (boot device EWF enabled) with IDE adapter
    • M2-ATX power supply (damaged automatic startup/shutdown controller)
    • *onboard audio connected to JL Amp
    • *mic, VGA, and USB cables run to dash to connect to:
    • Mic - RadioXtreme radio
    • VGA - 7" generic touch screen
    • USB - USB Hub
      • Touchscreen
      • RadioXtreme
      • CD/DVD Combo Drive
      • Extension wire to inside of car
    • USB Hub and CD/DVD drive are powered by a custom built 12v->5v (regulated DC-DC) power supply in the dash (POL PS Construction was built by an engineer for me)

    What happens is on a hot day the system will usually start up fine but then at some point the entire system locks up on a hot day. After reading arround on the forum I'm not entirely sure if this could be my CPU, RAM, Hard Drive, CF card, or Power Supply. I am however worried about some things I've seen about the M2-ATX recently. I purchased mine shortly after they were released and see that other people have had trouble running a P4 on them. Mine has been running fine so far (with the exception of a short blowing out the startup/shutdown controller).

    What I'm asking is if anyone else has had this kind of heat problems with their system, or specifically with the M2-ATX. I have a bad feeling that if I have to replace the power supply then I'm going to have to just pull the system. I'm buying a house at the end of the month and getting married in September, so I have no money for a new $200 power supply (now looking at the Dsatx and opus). Thanks to everyone for your input and help...I'll continue to contribute whenever I can.

    Cool

    Get some monitoring software, so you can check if the temp is the problem, their's alot of little Software you can install to check the CPU load and Temp of all components. That could give you some hint....

    here's some SW that I use for this im sure some people here have some better ones....
    -aida32 , Free, very very light, good reports and live monitoring
    -SpeedFan, Freeware, monitors voltages, fan speeds and temperatures in computers you also can change fan speed (if supported by hardware) so it could help you....

    hope it helped!

    If this is just a temperature issue just try modifiying your enclousure to dissapate heat batter.
    Add a intake and exhaust fans. *the key here is intake*
    I know a lot of peoples problems is that all they have is exhaust fans. Intake fans help a lot in some situations.

    Also check and make sure its just not shutting down because of the processor overheating. If its the proc it could be u have a poorly mounted/TIM'ed processor/heatsink. If all else fails you can undeclock it and lower the voltage therefore lowering the heat output.

    From what I remember the P4 series were basicly small nuclear reactors as far as heat output goes *especially the presscots*

    Thanks for the suggestions so far. I've got to find some time to take the system out and work on it. I tried aida32 and speedfan. They can't read the sensors correctly, the temp just jumps around or disappears. I just moved and I'm moving again and getting married soon so I've got NO time on my hands... Thanks, and if anyone has more suggestions I'd love to know, or it's going to have to come out soon...

    Thanks!

    You just have a crappy carPC proccessor. I have no idea what made you choose that. Anyways, sell that processor on ebay, and buy a more efficient one. usually you can get equal money for a desktop P4 as well as a mobile P4, or for a bit more an embedded solution. Also have you tried adding fans (as above intake and outake) or at least removed the side cover?

    I am almost certain it is a temperature thing given by you saying this only happens when it is hot out, and that you are using a P4. Also, personally I think it would be better to run a P4 off of an inverter than an M2. The M2 is flaky at high load, which you have. An inverter sucks, but it sucks and you know it always will. And M2 will work until it dies, and when it dies it takes everything it can find with it. So be careful.

    Thanks 2k1Toaster. I'm going to try the inverter idea in the next few days. I can't believe I didn't think of that. The Pentium m idea is good too. I hadn't realized P.M. 478's had gotten so cheap on eBay. I do have one other option though. I see the mp3car.com store is running miniITX/Ampie/M1 barebones on sale right now. Surprisingly enough, if I can budget for it, my fiancee said I could look into switching to one of these. This would solve my m2 issues as well *assuming the M1/miniITX works better than my M2/iDEQ does*. My only question is how well will this run RR flash based skins? I am currently using CDR's MC2 skin and want to switch to his new one when it's done. I tried Freedom 2.1 while it was still available but it was too slow on my system. Also, I'm open to suggestions as to which mobo/bundle is better and why. I haven't had much time to research the miniITX yet, and they were much more expensive back when I started this.

    You can have the best of both worlds. There are itx boards out that support P4-M as well as Core 2 Duo if you want. I got my P4-M itx really cheap off of eBay. And it came with free RAM!

    Any via will be slow with flash. So if you want the FU skin (hehe ) then no via boards.

    i have a via mounted inside an ampie case, connected to a m-2 atx. This thing gets up to 170 or 180F, when it is 90 degrees out because my trunk is so hot. Then it just continuously reboots. Any ideas to cool this thing down. I tried venting the trunk into the cabin via a solar panel and 90mm fan but it doesnt seem to be working. I really dont want to move the computer because its already mounted and wired really nicely. Any suggestions?

    I don't know how common it is, but my car has an intake duct on both ends of the trunk, if you have something similar, maybe you could pull in from that. An intake fan on one, and an exhaust on the other side
