From what you have said am I right in thinking that it is not correct that the "chip needs to run at 75C for optimal efficiency" but more that 75c is the Max temperature?

For safty, we test it under ~ 85C, okey for some days. But ~90C is not good.
For performance, we find ~65-70C maybe better for both performance and efficiency.

Sorry to be a pain but can I seek further clarification. Understand about not wanting 85-90C but are you saying that the chips are better at 65-70C than they would be at say 45-50C ?
Rich
That is what he put. If it's long term... not sure. He has put they are working on optimizing on certain things I would guess this is in it as looking for best performance and efficiency.
I don't think you going to get all the answers you want today, but it's good to see we have a dev reading up. Likely the key to alot including best operation speed and running temperature are in the "smart speed". Which is still pretty new and were still learning about, and it sounds like it's still being optimized.
