step 1 - design the upgrade - designed a shroud to hold two quieter fans that pushed more air;
step 2 - cnc the piece - 6061 aluminum block. Notice the bevel...
.
step 3 - spice it up... my buddy milled out part of the plastic fan casing so the fan would blades would sit flush with the adapter bevel. Subtle touch but it looks awesome!
Step 4 - hack the shroud - we cut the openings bigger. Going from 60mm units to 92mm units.
old fan;
Step 5 - drill and tap holes... secure the adapter
DONE!
soooo....how quiet is it? Its not silent but thats because the back pressure from the air hitting the aluminium sub frame. Its loads quieter than it was before - anyone who says the fans in the ATI units are quiet is a liar - they need to hear my modded unit to understand what quiet is. These fans push out 2-3x more air than the old fans.
Cabinet fans are now annoying though. So those will be swaped out with a couple noctua 120mm units. After that - the only thing making noise will be the damn vortech and the air intake on my skimmer.
special thanks to my CNC Guru Blob-79 for hooking me up huge on this project.
