now see this photo. this is a huge mistake that bitmain did. if that jack was ½ inch taller 2 silverstone fans would make this gear really easy to mod.
I have complain about this more then one thread and others have mention this. So someone dropped the ball here.
Especially since this miner has 600 watts of heat to dump not 400.
The sad part is they decided to use 1 fast fan. This was in my not so humble opinion a fuck up on their part.
I thought I would tame the sound of this miner with no real effort and I would like it better then the sp20e. I will need to work hard to make the miner quiet. Just think slap on 2 silverstone fans in 2 minutes and boom a quite or at least a pretty quiet miner with little or no effort. Right now I unplugged the crazy loud stock fan and I am using the silverstone as pull. very nice no issues. but I downclocked to freq 225
I have a new mod in mind for the noise but that will be on tues.

Are you sure that the network port if blocked if you use the Silverstone 140mm fan? I've replaced the front fan on my S3+'s with the Silverstone 140mm fan and it goes just to the bottom of the network port and with a unsleeved network cable it fits fine. If the S5 is the same as the S3 as I suspect, then it should fit even if others have said it doesn't. If it's just at the edge, shaving a mm off the fan should work also. With one in the front and rear, it should be able to have the Quiet setting on the fan for both and still have enough airflow (hoping).
