Comment quiet case water cooling (Score 1) 720

move your machine into a nice quiet understated case like the Fractal Design R4. Use a single 140mm or larger low speed fan just to move the air through the case. Then water cool it and use a large passive cooler... Something like a Zalman Reserator. Once done, the only noise will be the pump(s) and the single fan.

What I didn't say, but was intending to imply above, is that was for older engines. My new Ford 4 cyl with the polymer intake manifold... not so much. Modern fuel injection manifolds are dry, and as cold as they can keep them. Plenty of room on the exhaust manifold shield though.

Young one, back in the day.... *ripples of time*

Before fuel injection, Automobiles used a device called a carburetor to mix fuel into the inlet air stream. Intake manifolds were wet -- meaning there was always fuel in them. In order to enhance vaporization at the carburetor and prevent fuel from condensing out of the air stream onto the sides of the iron manifold, stock intake manifolds were either bolted directly to the exhaust manifold (inline engines) or had a passage running through the center of them for exhaust heat (V engines). The alternative system used passages containing engine coolant coming directly from the cylinder head. Either way, the intake manifold's plenum was always at least 200 degrees F.

So, you see, it is possible to cook food on top of the intake manifold

I get that. I was tweaked by the "as the human eye would see it" editorial statement. "Color corrected high resolution image" would have been enough.

Although, now that you mention it, I bet a oil painting done by an astronaut in synchronous orbit of Europa would be great.

So, let me see if I understand this... You have a device that needs 32 watts of electricity to operate. You're proposing we power it with an RTG, which are typically only 3% efficient at heat conversion. So that RTG has to produce at least 1.1kW of heat. You're telling me that you want to land a 1.1kW heat source on a body whose surface measures below -70C, and whose surface is made of frozen ammonia, water, methanol, carbon dioxide, and methane. Anyone see the problem here?

This. My core i7 laptop with AMD graphics and maxed out on memory, is only marginal for use doing electronic design, eCAD and PCB layout. It's OK for software compiles; but, all my projects target smallish embedded processors. Time is money... If I have to wait for something then I'm pissing away money. I have the laptop because I needed a portable machine to carry with me to customer sites.

They're not talking about the Core i3/i5/i7 mobile processors for laptops. Those are just the low power versions of the desktop processors. They're talking about atoms, quark and other processors targeting tablets and phones and small embedded applications, those designed to compete with ARM. Apple made a choice, there were options they could have used in the Mac Mini that they didn't offer.

No, if it's properly designed energy goes where the controller sends it. However, temperatures are low enough to freeze the battery, bringing it below the point where it will function. There are many electronic components that just won't work at -100C; or, will be damaged by deep cold. Heaters are critical to operation of most of the components on a deep space probes.
