could i take a small freezer and cut two holes in it, put a hose from the hole to the intake fans on my computer?? would humidity be a problem?
 
yes, the cold air will have moister in it and it will condence on the hot conponits in side the pc.
 
Freezers/fridges are supposedly de-moisturizers, and when you close the door on it it takes the moisture out. so its SUPPOSED to work according to "professionals" that i talked to (yah right).

but i still wouldn't trust it. what happens when you open the fridge door and all that air comes into the fridge, you get more moisture. i dont think the fridge can de-moisturize the air as fast as it comes in, especially with a heat source the size of your computer sitting in their.

try it with an old computer first if you want, i'm interested in the results.
 
Okay, the air coming from the freezer will be dehumidified, just look at any psychometric chart (it will, of course have some moisture in it, but for that to condense the temperature would have to go even lower). The problem that could arise would be the cooling of the room temperature air which can have a substantial amount of water vapor.
 
I don't really know if that would work. The way fridges and freezers work is they pull the hot air out of it leaving just the coldness, or something like that.
 
do it man who cares if you screw it up then no1 else will try it! :D

4w4k3 is rigth try it on a old computer if you are serious.

*shudder* :D
why is it that you wanna do this? hahaha, seems like you have a little to much time man . lol

Or he wants a cool (as in temperature) computer. Just look at vapochills.

If you really want to do it safely, I could probably come up with a few ways that would prevent any condensation, or else, as was mentioned, you could just try to do it how you originally planned and see if it works
 
im intrigued as to what your methods are

Basically monitoring the temperatures at a few places and doing some calculations with a psych chart. Then assume reasonable ambient temps and humidity ratios/relative humidities. Do some mixing calcuations somewhere in there.
 
haha, i was thinking of just putting a small freezer next to my computer, and cutting two holes, one in each side, then taking rubber hoseing and connecting it to one hole, then fasten it in front of one of the fans(mabey both), i dont know if it would cool the air fast enough though, im not worried about condensation too much,(cold air holds less water, warm air holds more) as the air heats up, the humidity should go down since it can now hold more water, if you know what i mean. the main reasons i want to do this is-
1. its fairly cheap, i have a small freezer already, all i have to get is some insulated air ducts,
2. ive been overclocking everything (ram,cpu,video card) and it gets pretty warm,
3. i like my room about 80, so the air going in to the computer is pretty warm to start with,

haha, i just got an idea, i could seal up my computer really good, and have the inside refridgerated, insted of just blowing cold air in, i could put the cooling unit from the fridge into the computer, hmmm case temps of 0 celesus.........

That’s what I was assuming you would do. I was just giving a safe way to do it; probably overkill though.

I would actually be concerned of the opposite – that the fans would not be able to pump well enough. You’ll be adding a bit of fluid resistance to the air flow (friction factor = 64/Re for laminar flow) both on the intake and exhaust (I’m assuming you’ll be exhausting back into the freezer)

As I said before, the cold air isn’t what you need to worry about. It’s the warm air that can have a significant humidity ratio (more relevant here that relative humidity). As this air is cooled to its saturation temperature water will condense.

How warm is warm?

Damn that’s a warm room. I like to have mine at ~65F if possible.

Maybe if you can think of a way to perfectly seal it so absolutely no outside air gets in.

If you really want to do something with your freezer (and don’t mind tearing it apart), use the compressor to build a direct die vapor compression CPU cooler. You can only do so much with case temperatures and at some point you need to check if the HSF is the limiting factor.
 
I would recommend exhust to the room, and take fresh air in to the freezer to cool as it probably wont cool the warm air from the case fast enough and the room would be a few degrees cooler,
also try putting a filter of those anti condensation crystals in between the freezer and the comp, this should absorb any residual moisture as most will be removed in the freezer, this works for me in a fog chiller so i dont end up with puddles, just remember to renew or dry the crytals about once a month.

That really depends on the heat load of the computer and the ability of the freezer. One reason for exhausting to the freezer is that the air would already be dehumidified (at least somewhat compared to ambient), so there wouldn't be too much worry about the air being dehumidified inside the freezer.

Desicants (those anti condensation crystals) might help, worth a try at least but their performance can be quite limited and a pain in the ass since you have to constantly replace them.

Ehh, just try it if you think it will work. Just be aware that you're taking a risk in doing so and don't be too suprised if something goes wrong.

Those are only single-phase change units right?
