Guys,

The temps on the 6x zotac 1070 minis on this onda D1800 board is bordering on unacceptable for me.
Acceptable to me is all cards running equihash below 65C. The hottest card#0 ~ 68C and card#4 ~ 66C.

I already put a 9inch industrial fan(45W) blowing directly from the back. The fan is centered on the card#2 and is blowing from the back to the hot aisle/section of the room.
The hot aisle/section has a 14" industrial exhaust fan taking the air out. This creates negative pressure.
There is an open window to the outside beside/near the exhaust fan.
We stick on some insulation board/material so as to funnel outside/colder air away from the exhaust fan so that it only exhaust hot air and hopefully the colder air will circulate to the cards.

Suggestions to get the temps down would be appreciated.

I have a 8 x 1070ti with less than an inch gap in between, running cool 55-65c, with a 20" floor fan blowing air from back to front.

Point the fan to the top part of the GPUs - the heat is likely coming out from the top more than the front outtake.

OR

get a few Scythe fans to draw out the hot air from the front - I think Phil has a good example of this in last few pages (maybe in the previous thread)
