It's a great Idea............. kv
Thanks it's always good to hear positive feedback. There is enough space left to fit 2 medium sized turkey

So are you ignoring the discussion about the freezer "exhaust", or did you miss it? Inquiring minds want to know!

Hey guys I think I found a cure for cancer while I was attempting to clean my humidifier.







I don't think that even e-coli or cancerous cells would survive in that sh*7.

By the way, this looks like a good heat conductor what do u think if I add some of this "alien lifeform" to my coolant ?

Yeaahhhh, I wouldn't do that... lol... it might end up building up inside your pump.
The best coolant to use is 100% or 99.6% as close as you can get, Ethanol. I.e. Methylated Spirits. It won't conduct and it wont freeze until -114°C and it won't boil until 78°C, but under pressure the boiling point will be raised.

at first the cooling system that you made looks nice
personaly i would not realy worrie on the hoses that you used as long there is no mechanical stress in the system
that means also that with temparatures of -10 the cooling fluid still have to be fluid, vodka is nice to use doesn't freez up if your pump stops running and keeps everything inside your cooling system clean

the only thing is that plastic hose (doesn't mater which plastic) don't realy conduct the heat/cold that good
you could use better copper tubing or aluminium, your local aircon technichian deffinetly has some scrap lenkts that you can use also a good one is Stainless steel (but hard to bend in the shape you want)

still i am suprised that your room is heating up that quick How big is your room (cubic meters)????

and your computer works with a CRT monitor or not ?

i doubt that prolong the life time of the hardware is one of the main reason

if you don't change annything the computer and hardware is still running after 10 years (i live in the tropics and the computers here does) at that time you're using already a long time something diffrent

Still than nice system

How are you going to keep the pipes cool?

Plastic can get very brittle and shatter in cold. Have you ever tried to use a vinyl extension cord at -20?

Monitor the condensation on the outside of your tubes carefully, especially in the summertime. You don't want the innards of the computer to get moist. Excess humidity may not be a problem for you in the dryness of winter, seeing as how you already use a drum type humidifier to try and compensate.

If your cooling system is split between elevations (upstairs/downstairs) keep in mind that the coolant pressure in the system will be higher at the lower elevation-downstairs. If the coolant has the specific gravity of water, a 10 foot change in elevation will cause the liquid pressure at the lower point of the system to be about 5 psi.

Add a coolant reservoir at the highest point. Centrifugal coolant pumps generally have a hard time if any air in pipes accumulates at the top.

Did you discover that guck in your humidifier while investigating the possibility of running the hoses through the air ducts? Man, throw that humidifier away. I bought one just like that when I lived in Winnipeg. We were getting sick quite often until I discovered that bacteria and mould infested gelatinous slime in the humidifier.

Looks like your stove was recently raised. I did the same thing too, with the 4 inch board nailed at the bottom. It was too low to be kid proof. And that Jana box? I haven't seen the Jana brand for years. I thought they were out of business.

EDIT: Oh, I just remembered - in case of leaks, Propylene gycol is not toxic. Ethylene glycol tastes sweet but is poisonous to pets. Major liver damage.

Actually the mold can Mutate your DNA and Cells become Inefficient during reproduction. There by compromising your immune system response and it's all down hill after that..................... Trust me I know.

Like a domino effect then age progressive decease's now take a whack at you and boom your buggered up.

God, quit handling that sh.....t* makes my skin crawl.

Wow u mean that yellow goo in my humidifier isn't a birthday cake left over by previous tenants ? Would have been nice to know, before I used this as a spread fro my peanut butter sandwich. This makes me wonder bout my cat that went missing a few days ago after I fed some of this humidifier stuff to it. Come to think about it, there is a strong smell coming from underneath the fridge...

I forgot to mention that I am going to implement a 5 gallon tank into the system. The tank will sit in the bottom of the fridge. Water entering it will precool before heading off to the radiators. I can eliminate any air in the system by adding more coolant to the tank as the pump circulates it from downstairs. I have to be careful as not to turn off the pump while the plug is out, otherwise the pressure from the top will cause water to spill out of the tank.

Here r some pics of the tank:


The plug you see screws into that whole (Yes I will put some teflon tape around it)




Just a shot of plumbing on the side of the fridge

Thanks for the suggestion. Do you know where I can obtain it ?

Well I lied about a room. The place I am in is more of a closet where Santa keeps his midgets

The room is 9 x 15 feet with 8 foot ceiling. I have a 22" LCD monitor that produces very little heat. Perhaps the heating up of the room has to due with the steam released by my body during competitive game play (especially when I am not doing 2 well ).

Oh, and I see no reason for using metal tubing inside a freezer as it will not add much of a performance boost (two triple 120mm fan radiators are enough I think). Besides, I am trying to avoid mixing different metal to prevent corrosion.

What for? The pipes are PVC; there is no need to keep them cool. If there is any condensation forming on the outside, I will wrap some insulation around them.
