Yes, its what I recommend.
I understand with these fans an S5 will run quiet and cool. Will the stock fans run equally cool albeit louder?
Stock will likely still be cooler as its just a crazy amount of cooling. The advantage of SP120s is they are much quieter while still keeping the S5 in an acceptable temp range at most ambient temps.
But then again the user netcoingeek indicated two different fans completely and keeping temps 60-62. We need real world environment to see which fans really work before spending any money on them. Is anyone here currently using the Corsair high pressure static fans now? Also, are there screw holes on the other end of the box to install a fan and is there an extra fan connector inside the miner to connect to? Is it a PWM connector that controls the fan?
There are holes on the back side of the miner to connect a 120mm fan to it.
Actually both the front and back plates are exactly the same, just that the "front" one has the controller with LAN and LEDs.
There are 2 PWM connectors on the controller.
Though the web interface has indicators for 4 fans, are the other 2 the 3pin ones on the side?
