Hello
I have this fans
Silverstone Tek 140mm x 38mm Fan for CPU Cooler and Computer Cases Cooling FHP-141
but Antminer on 350 mhz have the 75-78C temeperature
More overclocking is impossible
but the sound is much less
but the room quickly heated as the air coming out is much hotter
if you look at what i posted i also use a delta fan with 151 CFM as push i wouldn't use the Silverstone alone or it will get hot fast and I use the Silverstone on the P setting not Q .
