Just in case anybody's interested I had a play with TDP reduction to see what the best performance would be with reduce power usage, heat, wear and tear etc... on my 1070.

At stock I get around 367 Sols/s with the new release. Reducing the TDP gives the following:

TDP Dec.	Sols/s
0%	367
10%	363
20%	355
25%	350
30%	343
40%	317

I've gone with a 25% reduction in power usage which only reduces Sols/s by ~5%.
