    PIC'S-WuNgUn gets started on the carputer (H2O and all!)

    Okay...finally got some time to work on the actual heart of the in-car system...the PC itself! (Time, because the car is in the shop!)

    Mounted up the water blocks (yeah, it's liquid cooled...what'd you expect!?), riveted out the mainboard tray, mounted the pump, etc...
    From here, I think I'll wall it in with clear acrylic...at least the front and back side. And this is going to sit in the spare tire well...









    Note the tubing and the spiral anti-kink sheathing match the body colour of the car As do the VGA and north bridge water blocks...

    And of course, the center piece of the whole system...the ASUS Xonar D2's...one for the passenger, one for the driver...
    4 channels each for front/rear high/low network (active), plus another channel on one card will do the center/VU meters and on the other card, the sub out channel...

    nice... what'd you use for the liquid cooling apparatus? and what was the damage for something like that? (if you dont mind me asking)

    I thought about doing liquid cooling in my carpc, but since I live in chicago I'm afraid that it can and will freeze the liquid in the winter (even though the coolant has a lower coefficent of freezing it can still freeze). And when water freezes, it expands, and may cause a leak in the plumbing.

    I'd be more worried about the engine block myself...
    And I live in Canada, so I'm no stranger to cold weather...
    I think when I park the car for the winter, I'll pull the PC out, even though I'll probably be running 50/50 coolant.

    you are going to get air bubbles in your system that will eventually kill the pump just due to the normal road shunts and bumps

    Have you thought about going away from ethylene glycol antifreeze to propylene glycol? We've run it at 100% (no water) in Michigan and Chicago. It's more expensive, but you're not looking at a large quantity for this . . .

    We like being able to eliminate water in the system, because propylene glycol is non-corrosive. We've used Sta-Clean; other brands are Prestone LowTox, NEO, and AMSOIL.
    .
    If just enough is really good, then too much ought to be perfect.

    This is why I'm using a resevoir and an filler neck

    There is also the matter of exposed aluminum and (possibly) having two dissimilar metals in the loop...
    The ethylene is rather 'thick' as well...
    I might go for some fluid designed for PC liquid cooling...if the freezing point is sufficient.
    I was contemplating having the whole tray, water-loop and all easily removable for winter storage...

    Having no water -- using just propylene glycol -- eliminates the dissimilar materials issue. Pure propylene glycol isn't so much more viscous than water that it will create a problem, and it won't freeze in the temperatures you'll see.

    Whatever coolant you use, if you do choose to add water, use distilled water and you should see less corrosion.
