Hehe, this reminds me of some aerodynamics testing I've tried in my Silverstone TJ09B/W.

Things I tried (the case MUST be closed, and you must have a window for these ideas to work; either that, or you must have x-ray vision LOL):

Incense smoke through intakes (doesn't really work, though, if your fan is really powerful, as this disperses the smoke far too much for you to see the air flow pattern).

Strips of paper or light plastic (like from a shopping bag) taped at strategic places, which should show how the air is moving.

Remember, the case MUST be closed for this idea to work. An open-sided case doesn't work because the case is a closed system; the internal aerodynamics are completely different with the side panel off.

Hope this helps!

(By the way, I own a CM690 too. When I get pictures of that rig, I'll post them here. )

LOL

Incense smells great! And don't worry about your computer retaining the smell. It won't.

use some primer first. then use engine paint. i like dupli color low or semi gloss paint. its like $5.5. here in the US

so I had an idea. I think I'm going to clean up the fan mounts on the top of the case (cut them away), and then add a window with a single 120mm fan in the middle. Definitely haven't seen that done yet. probably going to paint some of the plastic trim on the case white to give it a little more definition too. should end up pretty neato. will post pics as a work on it.

ok so if iandroo is willing to be brothers in paint, I shall paint the plastic trim white. As for the window mod, behold:





I didn't actually do any work to the chassis or clean up the plexi or plastic, so there is still a fair amount of cutting and sanding to go, but you get the idea.

before I installed the window, I covered the top and ran orthos for 4 hours. Temps (with the standard room temp) stayed the same for the most part. At one point ambient was 2c higher, but the processor temps and all other temps remained the same. I think it had to do with how my computer was setup previously compared to now. It's sitting on the ground and only about 4 inches separate the rear of the case from the wall, so I think a few factors effected the results. Still, I didn't, and haven't seen any significant temperature change. The way my hs/f is designed (open) it draws air from above below and behind, so I'm pretty sure having those top fans running just created unnecessary turbulence and ended up canceling themselves out as far as efficiency. I'm still not sure about the white trim, I just want a little bit more "flair" on the exterior to balance the windows and blue paint. It's between that and some sort of graphic next to the side panel window. And if I do that I'll probably add a large graphic to the other side panel too. What? I have no idea and am open for suggestions on both the paint and the graphics.

I did the fan bay mod today but was so excited to get it back together I forgot to snap a pic, even had the camera on the table with me

Overall I'm not happy with the fans I got so I just ordered 4 Yate Loon 120mm x 25mm UV Reactive LED Fan - UV Blue (D12SH-124UB). The specs said 89cfm but they are also supposed to be pretty bright. Once I get them in I will put 2 of them on the front and 2 on the top! The CM690 should be lit up now!!
