super cool air? how would you use -50 degree to cool your pc

My brother lives in colorado, up in the rocky mountains in gunnison, at 8000ft above the sea...

Their AVERAGE winter termperature is -50 degrees Celsius. Everything is snowed up in winter.

I was wondering how residents of places this cold might PRACTICALLY use the cold air to cool a PC for extreme overclocking.

The biggest problems I forsee are:
1. Ice could pile up and prevent air flow.
2. Ice flakes could be drawn through intakes and the like into the computer where they will melt into water and damage components.

Any ideas on this?
 
Condensation could be a big problem trying to use the air directly. I assume they have to use a humidifier to keep from dessicating at those elevations and desert like humidities. Maybe liquid cooling and put the radiator in a mix of outside/inside air at just above 0 deg C.

.bh.
 
I would use liquid cooling. Put the radiator in a box or somewhere where it wont ever go below the freezing point of the coolant (like a garage, or attic). Of course you might end up with quite a long coolant hose......lol!
 
you would need: water cooling + ANTI FREEZE coolant 😀


Put the radiator outside for ultra quiet operation and -50f sweetness


actually im pretty sure you wouldnt need a radiator at all, 3/4" ID hose for a few feet outside should be able to cool its quite well since its so damn cold.

thats exactly how they use it.

But some take it even further. They dig about 50-200 feet underground and use the frost point temps of the earth.

They use copper coils and bury them. The temp down there is very very cold, and it maintains that temp yearly.

Of course you'll run into a few major problems. One is condensation. The temps of the coolant will most likely reach below 0 at some point in time, and your tubes will condensend. So your going to need to tweek your coolant.

If your thinkn about poping the computer outside in the sub degree temps, then i would not recomend that. You'll most likely condensend somewhere and short something out.
 
So the only practical way to do it is to "water" cool it with antifreeze and place the radiator outside?

anyone knows of a reasonably priced commercial cooling solution that can survive those temperatures?

You dont really need a radiator, just some tubing outside in the snow or on the ground since its damn cold out.
 
would you need to use the special CPU protection that they sell for phase change / cascade cooling (liquid nitrogen cooling)? since the water will be at -50 degrees? I would assume so...
 
Yeah... condensation is not your friend. Coating your mobo/assorted parts in acetone or dielectric grease helps though, from what i hear.
 
As was suggested above, maybe there is some unheated attic space as you don't really want to be using -51 directly. You want to keep everything just above freezing so you don't get so much condensation. Anything colder is more hassle than it's worth, except for something like a Cray.

.bh.
 
I am crazy! oh wait you said cray, nm 😛

But really the biggest problem I see is that the outside temp fluctuates... if you do set it up like you would a phase change cooler then you can really get phase change temps without the expensive equipment... but the temps will rise on hot days and dip on colds... so you will have to constantly adjust your overclock...

I would think it will be more work to run antifreeze tubes to the attic compared to placeing a computer against an outside wall and going straight through the wall, with a special drill and the like you could use a one foot tube to get it out (hang a heat sink against the wall on the outside?)

Does anyone know of a board that can set clock speeds based on the temperature? ie, you make a chart where based on the CPU temperature it increases or decreases the OC?

Sure about this? Anything below the frost line in a given area does NOT freeze, and is not super cold. Anything above the frost line is subject to below freezing temps. That is why folks bury lines and tanks, etc, below the given frost line in a given area - to prevent freezing.

Regards,
 
CV has it. The temps in deep caves are about the same year round and certainly not below freezing. And the ground below the surface doesn't usually get as cold as the air. Air that is free to move gains and loses heat relatively rapidly while air sealed in a space acts as an insulator.

.bh.
 
Yeah. The deeper you go, the warmer it gets. If you go deep enough, you can easily pump water down there and turn it to steam to run a steam turbine and generate electricity. If you are willing to go deep enough.
 
go down deep enough and you hit LAVA...

Indeed the frost line is the point at which it is no longer sunject to freezing.

If you dig the pipes deep then it DOES cool... in the summer... in the winter it heats. Basically the temp in the ground is about constant at that depth, while your home temp fluctuates.

I would have to say no to that and for a very important reason. First off it is impossible for the average Joe to dig that deep.

And at that depth you have hit water. My dad had a well drilled so that he could have water, on top of a HILL that he lives on. That well is 160ft deep, and the well casing is about 20ft into this cavern of water. That means that the pump is submerged in 20ft of water.

Also it would take a loan to be able to dig a 200ft hole. Because our well cost my dad $6,000.

In reality its more like 5 to maybe 15ft, and I doubt if it would be that deep.

No offense, just letting you know the facts. When it comes to actual work like construction, mechanics, and etc. I know more that than the average person.

i would like to see what happins when you coat the MB with acetone.... hmm... corrisive liqwid on elctronics. great idea. I think there are a lot of exagerations here. i do not belive that there is anywhere in the usa where the tempatures avarage that. we hit -20 for on mabye 3 or 4 days every year. one of those sometimes reaches -30 or lower. I am going to guess the avg temp there does not go below -2 or -3 degrees F.

wont work on quads.

Its been shown and proven that TEC's wont work very well when you amp the voltage on a quad north of 1.5V

Anything south or at 1.5V, high end water can get close to it, so it defeats the whole point in tecs.


And a quad north of 1.5V+ will draw near 300W of heat. If you know your TEC's then you know what happens at that point. :X

Heres an article where someone actually messured the heat output.

"The closed horizontal loop is placed below the frostline (1 to 2 m underground)."

your correct.

However on the history channel, i saw a document where they were digging 50-200 feet for a good geothermal tap. Also i remember them talking about good taps being that deep, and costing thousands and thousands of dollars.


Im not saying this is a route for the average joe. Because of course its not, but im just mearly stating what ive learned and seen.


I hate to quote something on hardforums but he knows the simular setup routine.

That link is info on how to heat and cool your house.

I saw the same thing the other night. In the summer it keeps the house cool, and during the winter it keeps the house warm. Now during the winter I would have to doubt that they use just this method. You would still need a heat pump.

I think I'd want to moderate the use of extreme temperatures. One guy buried a large sealed reservoir underground, running the hoses into the house. Another guy laid 1/2" copper tubing across the sunniest part of his lawn, burying it about a foot down. He would run the sprinklers in the evening or early morning, so the ground would still be wet during the hottest part of the day. And another guy just built a low-wattage evaporative cooler with some 4"PVC, Y-elbow, a shower-nozzle, and some wadded abrasive pads or other filter material, and some carefully-coiled 1/2" copper tubing.

The evaporative cooler idea could be improved by putting the cooling-tower outside the house, using a separate loop to circulate the CPU-loop through a bath of evaporatively-chilled water.

But it would have to come indoors when wniter temperatures dip below freezing, or find some mechanism that would introduce temperature-controlled amounts of warm water with the cold water.

😛

well someone asked how you would utilize it. Yea it keeps the house warn duing winter, they say something like temps are kept at a solid 55F all year long. Which is about 14-15C. That being said i dont mind my coolant being 16C-18C. 😛 My coolant currently is at 22C. Dayam funky weather.

Who heard of it being 90F in november? Welcome to Cali. :T
