Heat dissipation of tubing.

post #1 of 10
Thread Starter 
I'm fed up with wrath's heat output. 250 watts running mincraft, 150 watt idle, and I don't even know what peak load does. Solution: Put radiator outside. Issue: I need 20 feet (10 each way) of 1/2' in ID tubing to reach a window and have enough slack to move the computer. How much heat will the tubing dissipate into my room when the outside temperature is 10 C hotter than inside? I have a 240 and a 320 rad to offset the higher air temperatures.

Unless the tubing is metal the heat dissipation will be minimal. Plastic is a reasonable insulator.
In radiator testing rigs they often insulate the tubing but that is for maximum accuracy rather than being necessary.

Yeah, plastic tubing will be fine I would think. And if not you could always buy neoprene tubing instead if you need to buy some anyways. I would think that might be a slightly better insulator.

I don't think there is any significant heat lost throught plastic tubing. Not enough for you to ever notice a difference.

But what bothers me is your outdoor temps.
You will have an even harder time cooling your rig with air that is 10° C hotter than your ambient.

But since you will be able to get faster fans, rads being.outside and all, I would get some really fast fans (3-4000 rpm) to compensate for the higher outside temps.

Careful, as far as I'm aware the reason people don't do this is because when the temperature of your liquid goes below your room ambient temperature, condensation forms. So if it was snowing outside, and comfortable inside, moisture will likely form and eventually start dripping.

OP is in California so below dew point temps is not likely.

Not necessarily. If that were true, that anything colder than ambient gets condensation on it, there would be a lot of wet stuff in every house!

I live in socal. My windows get condensation on the windows very rarely (2 weeks in winter maybe,) if it is an issue I can unplug a few radiator fans to raise the water temp until it isn't an issue.
