I have temporary switched to Kano Pool to check if hashrate will increase. It looks the same as on the Slush Pool.
Done 3 shifts

your time frames are just too short.
give it 48 hours.
next what did you put the minimum fan to you had it at 100% I told you set it to 50%
did you do this?
also set the volts to 0 not plus 1
and get a dc meter find out what your psu is sending to the gear at load if it is 11.9 volts that is part of your problem.
voltage sag lowers hash rate.
also screen shot this page from kano
notice the dips some times he goes off line
some time you may go off line. the big dips were my end the little dips were his end

My miner has been completely stock since I started it up, I think the fan is on Auto and temps don't go higher than 29C.
here is my chart but don't know what it means:

I am guess it's good since it's doing what it suppose to, will be getting 2 more miners next week.
I also saw that Canaan changed the payments accepted but when I placed my order I received an email asking how you would like to make a payment.
I replied back stating I would like to do a direct bank transfer like I did with my first order, email was received a few minutes later with there banking info.
My bank sent the payment the same date and 24 hours later my order was processing, two days later it shipped and I should be receiving them by Tuesday this week.
This is my second order with them and it was quicker than the first order.
