RX480 mining ETH, some tweaks for cooler running

So the ambient temps are up and this was keeping my RX480 up at 89C running ethminer. So bouncing off the thermal endstops which is something I was not too happy with.

I have the reference RX480 with blower cooler (As in the picture) so they do run hot but this is still far from ideal.

Going into wattman I mad a few tweaks and the temps down to constant 80C, far better. The changes where:

• Fan on manual with 1500-2800 as the range
• Temps with max of 85C, target left at 80C
• Power limit at -2%

The core clock is now sat at a solid 1266 so less power draw and cooler for the same results of about 24MH/s on ETH :)

I tried above 2800rpm for the fan but you soon move into leaf blower territory so I feel this is the best compromise so far.

BTW: If you missed my last post on this, Enable Compute in workload or you will only get about 16MH/s
