They are just as loud, but personally speaking the pitch on the fans is much more tolerable than the SP10.
Hey Matt/bobsag3 when are you finally going to send me my refund Minersource (Miner Hosting LLC) promised twice??
I was told to receive a refund on May 22, 2014 and on June 30, 2014.
I ordered on November 2013. Your company still has my $844! I told you I would be fine if you would just send me 1 BTC and it's done. I've been waiting more then 6 months now... 
Please send the BTC to: 15TrStnmq3G3NymjDQGPKfvGKGtd9x9945order number ending with: R....24732
to bobsag3 if this is a legit complaint please fix it.
@ Dallas5 hopefully if you are legit bobsag3 and thomas will pay you. you can then buy an sp20 for the refund.
Thanks, I've been waiting for a refund from Minersource for several months, I've tried everything and don't know what else to do, $844 is just to much to give up and let them have it. Shitty thing is more then 6 months after my order was cancelled and I was promised to receive a refund on two occasions they still tried to ship the now worthless blackarrow X1 miners.
Sorry for posting here, I will leave this thread alone. As I said I'm running out of options and I can only remind them in the hope they will do the right thing.
