Your 47 MH/s are fine. This is one of my water cooled Gigabyte rigs:
https://i.ibb.co/X3LGGSg/999-14-qwezrfuqtzgwije.pngThe 25% fanspeed is just a safety feature for my AwesomeMiner. It has 0 fanspeed, because of watercooled. The settings you can see in the picture. Iam using T-Rex with --mt 4 --kernel 3.
I think the speed of your GPU's depends heavily on the manufacturer and the cooling. I also have a few Palits and EVGA non-watercooled, but none of them brakes the 43-45 MH/s, even with same or higher settings and with just 50-60C.
I flashed a BIOS specifically designed for LN2 overclocking, so I have less limitations than stock cards and I can go a little higher in speed.
Of course I have a little more power consumption, but, considering the KW/h costs we have in Italy, the earnings are still more than the costs.
Anyway, I'm glad to know that I'm not doing anything wrong. Things have simply changed since the first "pills' benchmarks" have been shown.
