The second new device in this design.....the louvered panel directly above the Ninja. This panel is the exact width of the case, and forces any upward airflow to turn toward the Sparkle and the PSU opening. It is custom built from a large wall vent panel. The edge pieces are bent up at a 90 degree angle, which makes the panel very stiff....with no tendency to bend. It just wedges in, resting on some ledges, and held tight when the outer case panel is replaced. Comes out with no tools.
The next new device....the "maximum duct". This is made from a plastic cookie container, cut to be a tight fit running from the bottom of the case, to half-way up the Ninja. It is square, slightly larger than a 120mm fan. It also just sits in the setup without any attachment...comes right out. When the outer case panel is installed, it is held tight by a foam strip which pushes against the outer case panel.
Next the 120mm intake fan....a medium speed 120x20 mm Yate Loon from JabTech. It has the bottom mount flanges cut off, so it pokes through the very bottom of the case. This was necessary for the installation, to clear a bottom mounted PCI card. In order for this to work, the case feet were replaced by taller feet. According to previous calculations/tests....there must be a minimum of 1.5" between the fan blades and the desk-top or the floor.....for maximum airflow, with the least noise. I intend to sit this case over a wood box on wheels, with a built-in filtration system, but it can work as you see it.....with sufficiently tall feet.
How does it work? There is a P4-3.4NW in there.....idles about 65W, and maxes about 155W. Temperatures.....CPU idles about 31C @850rpms (23C ambient). Maxes about 47C @1350rpms. The Nvidia 6200 is right in the airflow path, and runs super-cool. The rest of the MB components are in the airflow path.....some air from the fan escapes out the back of the three-sided duct, directly at the board......and that's without picking up any heat from the Ninja. The heat off the Ninja has a separate path upward through it's fins.
The Sparkle sitting on top of this airflow path....cool as hell with it's perforated DIY cover. It measures around 35C running, no matter where I can get a reading. So far it's working great....I can post more/better pictures if there's any interest in this project. Working great so far...
