Does anyone know what the difference in pressure is (inches or mm h20) across the Antminer S9 when running at full rpm?
I found the specs of the fans (QFR1212GHE-SP01) and the CFM vs deltaP and am trying to calculate the actual CFM through the miner when running at full RPM.
THX
It's around 188 m³/h.
I thinking about use some
Prolimatech Ultra Sleek Vortex 140mm, I know that its 166 m³/h, but I'm talking about ~20 dBa at full speed instead of ~75!
MrKaizer I'm wondering where you found this information, just for my reference? Seems like it is reasonable, based on the fan chart for the model QFR1212GHE-SP01 that comes with the S9, that CFM would correspond to a differential pressure of 18 mm of h20 or so, and falls right in the middle of the chart for the model.
