Ultimate PC Exhaust Fan

thingiverse

Ever wished your PC exhaust fan was just a little more powerful? This shroud allows a Honda Accord (Euro) blower fan to be mounted in place of a standard 92mm case fan. Power draw at full speed is around 250 watts, you'll want a brushed ESC, ideally with a BEC for your microcontroller, to control this. Unfortunately, the interface for that and for PC fan control are different, so you'll need some form of Arduino or other microcontroller as an intermediary. Power can be taken from your case power supply: 8 pin PCI-E connectors are rated for 150w, so you'll need two. In some left-hand-drive markets, the part 194000-7402 may be available, which appears to be very similar, save for the fact that it has a different connector and spins in the opposite direction. I haven't checked in any great detail, so there may be other less obvious differences. If you are using this fan, you will need to mirror all 3D printed parts. ## Pros: * Can move more air than anything anyone can sell you * Allows easy connection to 4 inch/100mm ducting for exhaust system * Watercooling is unnecessary when you're changing the air in your case every half second ## Cons: * RGB is not supported yet * May overload your power supply * Shrieks like a mad banshee Still not enough airflow for you?
