I think the RAM I have is DDR333 Micron, but i cant remember. I underclocked it.

The HDD is a toshiba 2.5" low RPM (4500 RPM I think, came outta my laptop) Its in a morex 3688 case.

Are you using the MSI 6215 BookPC as your carPC ? I used to have lots of problems with it hanging when the ambient temp went up to 50C. I tried all kinds of stuff - better HSF for the CPU, adding a cooler to the Northbridge and Southbridge, heating individual components on the motherboard with a hairdryer to see which one was heat-sensitive etc. In the end, I sold the BookPC and got a mATX board as the damn thing was heat-sensitive everywhere !

Edit: Oops - I just re-read the thread and realized that you have a VIA.

I had a bookpc in there, but now I've got an M10000.

I cant remember having these problems with my bookpc, but that was a while ago

Hmm, going back to your first post, 90F really isnt all that hot. Whats the cpu core temp when the case is 90F? And is that 90F from a temp probe? or the onboard temp diode? Or simply the temp in the car? I have systems which I'm happy when the case temp is only 100F. And shchua had a really good suggestion, try to isolate the problem with a hairdryer/heat gun. And as odd as it might sound, have you tried running the system with the case top off?

You mean a bong cooler? heheh. Yeah, that'd be a riot sticking out the back end of a car. I can see it now..

ME: What's that problem officer?
OFFICER: What's with the doo-hicky hanging out of your trunk?
ME: Wha..?
OFFICER: You know, that contraption with the water vapor coming out of the top of it.
ME: Oh THAT! It's just my bong.
OFFICER: Oh REALLY... Please step out of the vehicle. While your at it, keep your hands where I can see them.

I can see how you could get lower than ambient temps with it, but it's impractial (except for the die-hard overclockers out there).

On that note, you've seen the new Zalman Reservator? Looks interesting. It'd have been better if they made it hollow though (instead of a tube with fins, make it a RING with fins on the outside and the inside).

jeezus, that thing draws 4.4A!
and, the hot side gets to be 156F while the cold side is at 50F. Without ventilation, that ain't gonna work

AHEM!!

... and you guys thought I was nutz for suggesting water cooling.

I present to you somebody who's done it:

Yes! It wouldn't work too bad if you had a good place to mount the radiator. That is the first problem to get over.
