NIGHT STALKER
Morning madness once again, Byrd's daily dose of What did you do today is to blame.:
"840AV innards (which has a Rocket 40Mhz downstairs which I put a fan on nearby for that)" got me thinking about the backplane squirrel cages for PCs. Couldn't find a small enough blower for the application so I tore a very cool PC VidCard's heatsink off for some caffeine deprived playtime . . .
. . . HeatSinked 33MHz CPU is in the Q605 and the cooler is mirrored to to bottom, so bear with me . . . []
In my piccie searches for backplane plate blowers I found a very rough example of the printed RocketNozzle housing I'm proposing:
Of course it's the wrong kind of fan unit altogether, but imagine it in NuBus backplane slot configuration with rectangular opening and my SCSI II cable protruding from the center.
RocketNozzle(c) would work much better without the SCSI II daughtercard, dunno if the DSP board would cause less constriction and turbulence, but every Rocketeer lusts after the daughtercards. Therefore the cage would surround the connectors and have an ultra-thin laser cut picture window bolted down to the clear filament printed baseline assembly.
Intake would snug up to the heatsink along its bottom edge and block left and right edges to pull air straight down and across across the turbine bladed heatsink. Lasercut clear plexi cover abuts the daughtercard PCB window and the bottom surface of the cage would be modeled so as to all but touch the Rocket's PCB and any component along its underside.
Gotta check clearances, but one long plexi window allowing air to pass over the solder side of the daughtercaud PCB would be perfection. Should work out!
Of course I inevitably ran into some laptop blowers that might be better, that or a higher capacity, right size unit from an IMac or the like might be better. But the muffin thing is just too cool for school. []
Then again if the topside is open and bolted up to the picture window . . . LEDs shining out the @$$ end of your RocketMac anyone?. h34r:
