Ducting update.

NICE WORK MAN

[Avid6eek]

Nice work compy....those temps will only get better as we get further into winter. If I had a setup like that I'd probably spend my night doing some overclocking. I think it's supposed to get down to around 10-15F tonight. That could get me another 1000 3DMarks.

i chaged my duct a little. Right now I got 1 tube going from the window directly on to the cpu heat sink. There is a 120mm @106cfm blowing into the tube,and the 35cfm on my aeroflow. Current out side temp -2C (28F) and my cpu temp is 16C (61F) and dropping, system temp 8C (46F).

Good job. I saw the picture when you 1st showed us. Poor-man cooling-Great. My P4 is @ 18C idle, no outdoor intake duct. No heating yet, but I live in Texas!

[ari4324]

LOL its gonna get down to 65F here

[CompSnake]

its -6C right now, and im running a system temp of 7C and a cpu temp of 15C. its kinda hovering around there, if it gets any colder ill let cha know.

[CompSnake]

Oh and as soon as i hooked up the duct there was instant frost on it, im gonna hate to see whats its like at -20C

[CompSnake]

6C, 14.5C

Dont ask my temps<img src="i/expressions/face-icon-small-blush.gif" border="0">

Be careful, Compy. Heat-Bad, H20-Worse

[Avid6eek]

As long as all the air inside the case is coming from outside, then the frost will stay on the outside of your case. You should use insulated ducting when it gets really cold. Also, using noise dampening mats will double as insulation for the case. The inside will stay nice and cold.

I have to give you some credit, you have bigger balls than me for trying something like that compy, but it is a great idea. I would just be too scared that there would be condensation forming inside and then everything shortcircuiting and being destroyed.<BR><BR>But as I have been thinking about it, the only problem I can forsee is on a day with a high humidity . If the fan sucks the air into the case and causes it to condense into water. But that is only under extreme conditions do I see that happening. But one way to eliminate that is by having the fan blow the air uphill, that way if any water vapor does condense it will just roll back out of the duct. Maybe even putting a piece of foam or something at the end of the duct, which would catch all of the condensed water before it went into the pc...<BR><BR>But like I said earlier, great idea compy, way to make a very cheap and very effective cooling solution!!

[Avid6eek]

Stangz....for water to condense, the surface it's touching must be lower than the dewpoint of the incoming air. This will not happen in the winter, because the computer components will always be warmer than the air coming into the case. The opposit will happen on the outside. There the dewpoint of the air inside the house is higher than the temperature of the case, duct work. This is because the air being drawn in is much colder. The only condensation Compy will see will be on the outside of the case. The air inside the case will be extremely dry. <BR><BR>The opposite will hold true in the summer. If he draws hot air from outside, and the inside of the house is air conditioned, the condensation would occur on the inside of the case. Of course, that is where you would run into a few minor problems <img src="i/expressions/face-icon-small-wink.gif" border="0">

I might put a duct to run hot air out my window

[stevo909]

compsnake, how is that possible? Your 120mm is blowing into the duct atone end, and yoiur heatsink blowing into the duct at the other?>??????? wouldnt the air just.....collide?

[Ginsu543]

At least they should... but then again, when I was a noob, I didn't know which way to put the fan, either. I had to read up on many overclocking sites before I figured that out.<BR><BR>But yes, cpu fans should blow <b>down</b> onto the heat sink.

[stevo909]

duh is right, i hahahahahaha i think mynes blowing out........hahahaha how can i change that??? just unscrew it and fliper around<BR>

[Ginsu543]

Yup, that's what you do. Just unscrew the four screws, flip the fan, and then screw back in. Should be a snap! <img src="i/expressions/face-icon-small-happy.gif" border="0"> You need to turn the fan around because you want to push air through the fins on the heat sink to draw heat away from them.

[danny16866]

yea thats what you do......just make sure that its actually blowing out before you do anything

[stevo909]

okay honestly, i never even thought of that. I thought it would come standard already blowing in to the hs, but myne was not????? WTF???? honestly havent touched it since i cleaned it hahaa<BR>

[Ginsu543]

Stevo, did you buy your computer pre-fabbed or did you put it together yourself? Or did someone put it together for you?

[stevo909]

i put the comp together, cept for mobo, cpu, and hs becuase i wanted as3 but i didnt know how to put it on etc etc. haha i changed it and now im getting temps of like 50*F and around 18*C lol

[Wolfgang]

Yes Shiznit. You put a cold drink outside on a warm day and condesation occurs. Im the paranoid type. If he has an out duct, that will form ice on the outside. This can build up until it reaches back into the duct and the warm air melts it...dripping down on his machine.<BR><BR>Im just saying be careful, sheezz.
