Water Cooling With A Car Radiator

sH4RD writes "Why go out and buy a water cooling system when you can do it with an old car radiator? That's exactly what One of The Twelve figured when he used the radiator from his brother's 1979 Toyota Corolla to cool his system. His Athlon64 3000+ can hit 2.5GHz smoothly now. Check out the original forum post complete with benchmarks."

    I really appreciate that he still used a glycol/water mixture. Pretty unnecessary, but certainly a nice touch.

    Radiators were made to have a flow of air over them, so putting a fan blowing over that thing would greatly increase its cooling abilities. Of course, he's still stuck with old shitty car parts under his desk...

      I don't think you really understand. A fan can only help a radiator bring coolant to ambient temperature. If this radiator already provide 200 times the required cooling then adding a fan isn't going to make it "much" cooler, probably not "any" cooler.

      Glycol is neat, but it isn't without problems.

      I was talking to an engineer who retired from PAX, but now does solely contract work.

      Anyhow, apparently there is a problem they found out with glycol. It coats the metal surface and of course transmitters produce lots of heat. So after a period of time this glycol coat solidifies. It becomes an insulator.

      I guess not so long ago, they finally started diagnosing OLD dead transmitter tubes. It is expected to burn out at some point in its lifetime and normally a diagnostic hasn't been done.

      Though there isn't a replacement yet for glycol as the tubes and compoenents were designed with its characteristics in mind.

      Though given he is not going to be using this system for a decade... it's just an interesting point to note.

    I hate to sound like an elitist, but this is fairly common practice for water cooled PC's. Except most people tend to use smaller heater cores. That, and tend to buy them new and clean.

  3. Would a five gallon bucket been easier? by MyNameIsFred · · Score: 4, Insightful

    With the amount of coolant in the radiator, would it have been easier to use a five gallon bucket? It's not like he's really using the radiator's fins.

      Quite possibly true. Also, car radiators are intended to work better on a moving car, in order to transfer the heat to the air that flows through it. Unless you dropped it from a tall building, a PC would have a hard time reaching the same speeds.

    why not use whatever they use to cool nuclear reactor cores to cool your computer

    It's water, but it's too expensive and hot for you. It's de ionized and monitored for purity so that nothing plates out and it does not eat your cladding, that's the costly part. But, under pressure, it's hot enough to light paper on fire. That's a little too hot for your little cpu.

    I'm not a car mechanic. Duh.

    Do not, learn not. Your loss. Ask yourself what's the worst thing that can happen. If you can live with that, go for it. If not take steps to mitigate the worst. If that's not enough, then you might not do it.

  6. Re:I was considering this... by Lisandro · · Score: 2, Insightful

    My main concern, besides noise, it's that it introduces another "break point" in the system; which means i'll have to monitor the waterblock temperature constantly (extra circuitery). Not only in case the fan dies; also if the pump dies, or the radiator becomes clogged. Besides that, it's all advantages.

    Other thing i considered was a smaller heatsink inside a pipe with two fans blowing, again, at low voltages (5-9 volts). If the sink is large enough this would work quite nicely, but dust acumulation is a concern.

    I'd much rater use solid aluminium sinks but those are quite expensive, so i still really don't know what to do with the whole thing.

    Can it be the "New" Beetle? Those are liquid-cooled and have radiators.

    They're not Beetles. They're bastardised abominations from the land of marketing. They're just VW Golfs with a funky shell on top --- decent enough cars in their own way, but if you want a Golf, just buy one.

    It ain't a Beetle if it ain't rear-engine air-cooled.
