This is the config i'm running on my SP20s... i'm using a PSU EVGA1300
you are drawing 24c/75f air in which is not bad for intake
you are pushing 77c/171f air out which is high , but you are pushing the gear at 1555gh.
what will you do for cooling this gear in the summer heat?
once your intake gets to 32c in the summer you will not be able to run at 1555gh.
i have an AC running 24*7 at 2 ft from the miners so they are always getting cooled air right into them..
i live in Venezuela so we always are at 32c xD
do u think i can improve that configuration ?
I would think you could. With the SP20's I have never had heat issues. Worst miner I had was a SilverFish 28 Scrypt miner first gen longer I had it more issues. I had to eventually keep a AC near it or performance would drop.
The ambient for sp 20's should be "0 °C to 35 °C". So your very very close to top end. But I'm guessing you could do more with moving air and exhust out. AC just is a little expensive to run for miners.
