Ok my computer isn't running hot I just want to do this to see how much it will lower my temps.
So my plan is to attach some type of 3inch or 4inch duct over half my ac vent in my bedroom and run it into my pc case.
My case has an intake right above the CPU fan on the side of the case.
So I will run it the duct from the ac vent in my room to that intake (about 8 ft).
That way the ac will blow right in the side of the case ontop of the heatsink and fan.
The ac temp is 73F or 23C. So it should work rather well.

Now the issue I have is what kind of duct should I use. I went to a hardware store and they had 2 types of duct
1st is aluminum 4inch wide /8feet long (flexable dryer duct) $9
2nd is rubbery/plastic; 4inch wide/12feet long (flexable outdoor drain extension) $8
They both flex about the same.
I can't decide which one will work better
The aluminum or rubbery/plastic one????
Pretty much the only difference is the material.

Well, let me chime in on this.

One word: Yes it works.

Yes you COULD have condensation, on the OUTside of the PC.

All you will be doing is cooling the ambient air temps. If you pipe the cooler air into the PC case, the components and case would be cooler than the ambient air temp. if the humidity in the room is high enough, the exterior of the case could sweat, just like a soda on a hot day.

When you turn the PC on, the interior parts (CPUand GPU mainly) will increase temps ABOVE the air, and if the air doesn't cause condensation from just being at ohh say 50F then the PC parts won't either.

The interior of the case (parts) will be below the room air. Hopefully the AC unit your going to use pulls a LOT of the moisture (humidity) out of the air and your not at 60-80 % humidity already

Yes it works, yes you could have condensation, you have to try it yourself for your situation.

Pretty cheap to try? Go for it.

EDIT. Just remembered. Hard drives aren't made to run at low temps. What about laptops? When is it bad to use a laptop in the winter? I don't own one and live in the desert, so it's nothing I know about.

EDIT again. Just reread your original post. The difference will be ver y very very small, your not using very cool air. Try it, but you'll maybe see 2-3C diff under load, and you'll need fans to help pull/push that air.

If they are equally flexible and easy to install, the more durable is the better choice.

Why even waste time on this? Can do something more productive? The results won't delight you and you'll probably be pissed.

I doubt the temp of the air coming out of the vent is 73F. Perhaps you mean the thermostat is set for 73F.

The AC will blow somewhat colder air than that into the room until the temp hits 73. If it used 73F air, the temp would *never* get down to 73.

^Good point. Also what happens when the AC turns off once the temps are reached?

@OP: It's been done and it works OK but you'r better off with water cooling.

Hehe. He is back to cooling on ambient 73F or so air. Where he will remain likely half the time.

Which is why this isn't really a very good idea.

Not to mention he needs to remove the duct when the system switches to heat :) .

Ok ok give me a break. It's an experiment.

Hey, you'll notice up above I didn't try to shut you down. The basic idea is good; thinking it further through shows its not so effective. But you don't find out how to think things through without experimenting.

Anyhow, you may find another use for directing that cool air. Your PC is expelling heat in a specific spot in the room . . . and my guess is that's nowhere near the thermostat . . .
