Case Fan Setup on Mining Rig

[skyglin]

Hello Guys, I need help on how to connect 6 of 3-pin or 4-pin case fans to a mining rig. Do you connect to the PSU or the motherboard? What adapter can be used to supply power to the fan and control the fan speed?

You can safely connect to either of them. In case you want to control fan speed, connect it to the motherboard as connecting it directly to PSU will make it run at a constant speed.

How do I connect to the PSU? Since PSU does't come with 3-pin cable, any adapters I can buy for 6 fans?

Buy an Adapter... e.g. 4 pin Molex to 3x3pin fan connectors.

You can buy 3 to 1 or 4 to 1 adapters to allow you to plug multiple fans into one motherboard header. You can also buy 3 pin to molex adapters to conenct directly into your PSU. I would expect that you will want to run the fans at 100% speed in order to keep your GPUs cool so either option will work equally well.

These Arctic F12 case fans are pretty quiet and move allot of air. They're my current favorite for affordable, quiet, and powerful airflow 120mm case fans. https://www.newegg.com/Product/Product.aspx?Item=9SIA2W047R6527&cm_re=Arctic_case_fan-_-1YF-000P-00017-_-Product
