I've had my Apollo for about 3 months now and love it. I started with Eco mode, then moved to Balanced mode and finally to Turbo mode. Temps were all good in the three modes except in Turbo, the miner temp raises to over 70c. I was cautious when I first started with Turbo and watched temps closely. After I felt confident things were good, I've left it mining numerous sites using Turbo. I'm currently mining at ProHashing and noticed that my hash rate is considerably less than 140MH/s. In fact I was sometimes averaging 115MH's on Turbo over a 2 hour span. Yesterday I dropped back to Balanced mode. I've watched the hash rate on ProHashing and the hash rate is better than when I use Turbo. In fact, most of the time they calculate it between 130 and 135 MH/s with a few jumps up to 140MH. I'm not sure why Balanced works better than Turbo on that site but I'm happy with the results and I'm very happy with the Apollo.
Thanks jstefanop for your fine work in building the futurebit miners. I'm looking forward to the next batch of Apollos.
