low cost and efficient "airflow" design

Hey there all! I just had some spare time and I decided to get my case airflow project rolling. Please see my pics (sorry about the date on the pic, I forgot to set it). It's supposed to be my prototype before the final design which is to be acrylic and velcro but this prototype works so well that I decided to stick with it (not to mention the low cost of this design, only $6 or $10 with 6A charger/converter and all connectors).

With this design, you can keep the CPU and sys temps at minimum (42C CPU 35C sys in my case, 30-32C room temperature). When stressing the CPU, the temp goes up to 48-49C (sys temp at constant 35C) and falls to 42C in less than a minute after the stress.

Hope you guys enjoy it

Hehe, interesting project. Could you please post another picture of it? I'm not sure I see exactly how it works... thanks!

Oh, and btw - check out our folding@home section, you seem like just the guy we need!

I checked the folding@home section but the common practice here is that when we don't use our PC's, we turn it off so it wouldn't be very efficient running the app. Thanks anyway Allan.

Mods doesn't have to be expensive for it to efficient. Though I must admit it still needs a little work in terms of appearance, hence the revisions.

So far I couldn't think of a better "airflow" and "airfilter" sys than this. The airfilter filters even the finest particles and there are no locking mechanism for the filter except the weight of the frame (I just cut and made a double layer out of the extra fiber-fill filter to make a "gasket").

BTW the "airfilter" that you see on top of the "portable clothes hanger" is a material called fiber-fill sandwhiched by a mosquito net and a 1"x1" moulding as the frame. For the air intake, I used a 8" exhaust fan that came with an excellent warranty of 3 years.

The "airflow" design frame is made of a 3/4" styrofoam with 2 120mm 0.35A 12V fans that I run at 9V (12V doesn't really make any difference). I connected the fans to a 6A Converter/Charger (with voltage selector) by means of a mono baby plug, speaker wire and alligator clips (much better to solder than the banana type plug).

Now, why did I do these mods? Simple, 'coz my sys is running stable and I really don't want to clean all the components that you see here all the time. Plus it's really cool

Good Luck on your Mods

Just an update I changed the wire mesh to welded wire in my sde panel styro and got a better airflow. I think if I changed the mosquito net in my main filter I could get better suction from the exhaust fan too.

BTW here's my Sandra burn in with the welded wire. If I remove it, the burn in will be the same but I like to put it in 'coz of the static/EMI (no instruments to measure it but I kinda like the way it looks anyway).

Well, the design is all about airflow to carry the heat generated by the pc out of the enclosure. The exhaust fan on top sucks the filtered air in and goes out the lower right hand side of the enclosure (where the tubes from the pc case point/exhaust). This is to reduce the air from recirculating in the enclosure. notice the placement, the fan is in the top left and the exhaust is in the bottom right.

Next is the PC airflow design which is basically pumping a lot of air in and letting it out in one exhaust tube pointed to the exhaust port of the enclosure.

You could also make your own design if you wanna suck air directly from the window
