5 x sapphire rx 470 nitro 8gb temp

hi
I have just started mining with 5 x sapphire rx 470 nitro 8gb in windows 10.
here is the info of the cards:
gpu 1 : temp 74 c fan speed 38% , 109watt
gpu 2 : temp 74 c fan speed 40% , 106 watt
gpu 3 : temp 74 c fan speed 36% , 99 watt
gpu 4 : temp 74 c fan speed 38% , 106 watt
gpu 5 : temp 74 c fan speed 43% , 110 watt
my average hashrate is 128mh
Is the temp ,fan speed ,hashrate and the power consumption of the gpus ok ,or do i have to tweak(fan speed,voltage,...)
Thanks
