Nice!
The fan on example has 110CFM and 19 dBA. Can you post your temps?
Some noctua fans has only 13.8 dBA with 88CFM.
All those specs are false. Never read packaging specs, its BS
Also for OP's mod, it doesnt matter how many CFM anyway, air will just go around the HSF. Not to mention a huge dead spot in the middle.
well maybe he will post his numbers for temps and I see a two fan mod to his idea in my mind's own mind.
Some one just posted a cooling design claiming great numbers with 2 fans attached to the blades. have to find the thread.
I believe fusing this thread and the other thread adding a screen to keep kids and pets away and boom a great heater. Maybe even a food dehydrator !

Although I posted the original link they aren't my AntMiners, I have some but the only mods I have done are an extra fan for push pull cooling. I came across the picture from a GHASH.IO tweet and liked it.
So, I think with the Philipma1957 picture the AntMiner can also be re-purposed as a great looking UAV, in fact if you fitted it with wireless you could mine, fly and heat all at the same time. I think BitmainTech need to know about this
