Thread: GTX 1080 FE Temperature & Power Requirements
Post: RE: GTX 1080 FE Temperature & Power Requirements
| Thanks. That helps to bring down the temp for dev3. Now dev3 is only about 6C hotter than dev4.
Any idea why the cards are running more than 70C?
Best regards,

You need to push the fans up. They should run < 70C with the fans at 100%. No, you don't need Delta fans to cool a 185W GPU, but you should probably put the s... |

More airflow? Not sure. You're not the first to complain of high temps, but so far I've not experienced them. But my chassis also push like 1000 CFM of air.

Thread: Building 4x GTX 1080 recommendation
Post: RE: Building 4x GTX 1080 recommendation
| You will need more power for your PSU as 4 x GTX 1080 FE will require at least 720W (180W x 4) and 750 W psu won't be enough.
i7 CPU should be able to handle 4 GPU. I'm using i5 and runs 4 x 1080 F... |

Thread: Building 4x GTX 1080 recommendation
Post: RE: Building 4x GTX 1080 recommendation
| I beleive 50% to 60% capacity is recommeended for PSU efficiency. So in your case you will need a PSU of 1500W / 1600W PSU.
Read here for explanation of PSU efficiency.

Is this the back panel you meant? Somehow this feels wrong and I feel dumb. I'm not sure which half of it should have been left on the card.
