New guy on the forums needs help

I don't know if condensation would be that big of a problem....

To get condensation to form on the case Relative Humidity would have to around the same as Dew Point ....

In his case it would have to be around 80-90 percent on the outside with low to minimal on the inside....
And I think with "Dehumidified" air inside he would stand even less of a chance...

I would have to say he would stand more of a chance getting condensation by "water cooling" because there is already water involved than there would be by "Air Conditioned" cooling...

Lets look at it this way... for example...

I have the AC on in my house (now) and I keep it 72deg F...Relative humidity in here is right now 25-30%

If I go downstairs (basement) I have copper water pipes that run everywhere . Right at the moment the "cold" water pipes have No condensation on them...But when the Humidity goes up to around 60-80% then I start to get condensation on the pipes... so....

I guess my point would be check the humidity of the surrounding room...if it's below 50% I would say you're goin to be safe...

I would have no problem trying this...But I do not want a hose running across my room to my PC....

Personally I would turn the AC on high and let it "chill" the whole room....

Also those little packets that come in shoes and other things to collect moisture....I'd put a few of those in the pc just to be safe...

Besides...condensation would only be a problem on initial start-up....if the AC and the PC ran all the time....they'd both be the same temp...

Karne,
Warmer air is indeed capable of holding more water than cooler air. I'm not interested in arguing the point. You can find the answer in any physics book or meteorology book. Please don't tell people this is not true. Ask any meteorologist or physicist. We try to keep these threads accurate.

To say that running cold air over warmer equipment could form condensation is false. Running cold air over colder equipment could cause condensation... would be an accurate statement.

Here is my proof: http://en.wikipedia.org/wiki/Relative_humidity

Daivd,

I concede your pointt that I was mistaken when I said that cool air over hot parts would cause condensation. Science class was many years ago for me. Sorry for the error. However the point of my last post was, using the now corrected info. the problem still exists, just in a different location. if the inside of the case is cooled too much and the air surrounding the case is warmer than inside the case, and all the needed dewpoint and relative humidy comes into play, he may run into this problem. Maybe not highly likely, but a possibility. It may in fact work wonderfully, but it has a potential concern, and he should, at least, be aware of that.

The second part I didn't make up. I came across that when I was researching this point. I provided it because I thought it would be interesting since it changed what was most of us were indeed taught. Here is the link so you can read it for yourself. By the way, it doesn't dispute your original argument. it just says that folks arrive at the the right conclusion for the wrong reason.

Whoa now, I just want cold air intake on my PC... not a physics arguement. We aren't talking cryogenics here... it's just an air conditioner.

[Karnevil9]

Hmmm....liquid nitrogen. Now that has possibilities

[RazorDX]

I have abundant supplies of it... but... have you ever seen what dry ice does when in contact with metal?

Wasn't there a post awhile back on here (by Cricket maybe?) that showed a couple 6800 video cards in sli setup that were cooled by liquid nitrogen? I thought there were pics of it and it was outrageously expensive. Anyone remember that?

Make the case a little larger and you can keep a few beers in there and let your pc serve double duty.
