Cooling idea, see if im crazy

[crossedup]

Okay, been thinking about this for a bit and have possible solution before getting the water cooling going.

Going to be summer soon. My 2 Barton rigs have okay temps right now but in a few months it will be up to 90's here in NC and i want to keep them cool. Starting plans now.

Went to the hardware store to check on some ideas, pic shows preliminary of one idea.

Going to add a pipe on the bottom of that thing and run it through the floor to the underside of the house. Even in the summer its nice and cool down there. The pipe length wont be but 4' or a little less.

Already figured out how to mount a fan on the end. The one i have on there now doesnt push enough air so i will get another one, was just testing the mounting.

Fan on the inside of case in the back, screw part of pipe through a hole in the back of case then elbow fitted ( as shown )and finally pipe added ( not shown, havent bought yet).

Will the extra addition of 30 degree cooler air in the dead of summer probably make any differance?

Should i keep my pipe radius the same, go up or go down? Was thinking keep it the same myself, smaller i wouldnt get enough air to make it worth it. Bigger and it wouldnt be able to pull enough.

Just comments before i try. Point out any flaws. BE NICE.

I am going to put air filters on it so no bugs.

It ought to help, Mama spider may wish to cohabitate, so the filter is a good idea. I would also do a dry run before cutting the floor as tubing/pipes will sometimes resonate and make a much louder noise than you would expect. If you can get the cooler air directly to the HSF it will be more effective than simply running it into the case.
Just my 2 cents.
Enjoy!

You may want to go up in pipe diameter. Remember, any bends will effectively double the pipe length as far as pushing air goes. I. E. one 90 deg. bend in a 4 foot pipe will make it act like 8 foot.


Guess you don't plan on moving the unit much do you?

Might want some sort of screen on the lower end also, rodents love small pipes.

30 degrees cooler, now there's a good deal if you can make it work.

Good luck with this idea

[Vampiel]

That should work.

[crossedup]

Thanks guys, no not really going to move it much Lep. If i do another one will take its place so thats no trouble.

Another thought, if i have enough fans in the case blowing out it creates what, negative pressure? If this is the case then i could almost do away with the fan blowing in off the inlet pipe as the fans all blowing out would pull in enough air anyway, has to come from somewhere and that would be easiest place.

Enough fans blowing out as in 2-80 mm on side, 1 92 mm on top and 1-120mm in back. Think this would be adequate?

[Vampiel]

It would suck it from the pipe (ok maybe I should re-phrase that). I would try it with and without the fan, see which works better. It's hard to say which one would work better, the best way to find out is to try it.

[leprechaun_40]

I'd run it with the fan, the exhuast fans will be pulling air in around the drives, next to the case sides, etc. You'll need something to push that cool air into the machine.

[Vampiel]

Im leaning more toward the fan as well, but you can find out for sure by trying both approaches. leprechaun_40 judging from one of your previous posts it sounds like you have some HVAC experience?

[leprechaun_40]

Vampiel, nope, but I have a friend who does

[Vampiel]

AH HAH, this kind of gave it away...

"Remember, any bends will effectively double the pipe length as far as pushing air goes. I. E. one 90 deg. bend in a 4 foot pipe will make it act like 8 foot. " <---- BTW this is TRUE crossedup

You may want to go up in pipe diameter.

Thanks but remember i have to go through the floor with this thing and my wife aint really happy about it as is. My rig is on the floor so i can hide it behind it.

Once i come out of the case with the pipe and turn 90 degrees and go through the floor the pipe shouldnt be but 3 foot or so. The one i have in the pic is 1-1/2" internal diameter. Ill try it with this one first and see what happens, can always make the hole bigger if success is good.

Its going in my rig pictured here
in this thread, the second one, the one with the red fans. Going to figure out exactly where to mount the pipe soon.

Hopefully i can complete work this week end while the wife is out horseback riding.

Would it be possible to add a fan to the end of the pipe thats down in the basement to help blow air into the pipe? That might help also. But to be honest, I'd go with water colling before I drilled a hole in the floor that big just to help keep my computer cool.

[Happy Joe]

I believe that Johnny F. is on the right track... with a pipe that small and the bends you might consider both a fan blowing in at the bottom and one sucking out at the top to help make up for the restriction, bend etc. I have noticed that sanitary fittings usually have a greater bend radius and would probably impead the flow less.
A good scrounger can reduce the cost of water cooling very significantly (to slightly more than the cost of a good (expensive) HSF (or less if you make your own waterblock).
Enjoy!

[crossedup]

You are all right, im afraid, after much thought.

What chance does a small fan like that have at pulling in cool air when there are all those larger fans trying even harder to blow it back out. Seems like a futile effort.

Am going to rethink the idea a bit.

You are right with the water cooling Johnny. Would rather do that but this seemed much cheaper. ( Have $2 in it so far.)

Got any good info links on that Happyjoe? I think that is my next step.

I'd definatly add the fan... Sure creating a vacuum will suck air up, but a fan would help out a lot...

Think of it in terms of cars... You've got naturally asperiated engines that basically are able to intake air by creating a vacuum. Add a turbo or supercharger to force the air into that very same engine and you've got yourself a CONSIDERABLE power boost.
