My current rig has:

  • 1 x Vega 56 blower
  • 1 x EVGA FTW2 1070
  • 3 x RX580 Nitro +
  • 1 x RX580 Red Devil

It's nice and I can mine either Ethereum with the hybrid Claymore miner or ZCash (albeit I still need to tune it because it crashes).

Unfortunately, the airflow is messed up:

  • Vega blows towards the rear
  • Nitro+ blow towards the front
  • The other two are OK with no discernible preference.

So, I thought of adding fans to build a specific airflow, but I'll need to build more rigs with homogeneous cards :)

HTH.
