Fan speed cannot change the hashrate power.
this. and if your running it 40 degrees+ then youre not doing it right. read the specs. the safe max temp is 40
i adjust fan speed all the time depending on the temp since i live in south florida but I never come off 10ghs + or - a little.
I think we're talking about different things. My x10 never falls below 10.1gh on the baikal dashboard. I was talking about the hash rate reported from a mining pool.
