Fair enough.
I didn't (and still don't) understand why people would buy a Nano to add too a custom loop, Why not buy a Fury X and add that to a loop instead? I can't see size being an issue as the Fury X also used a small pcb and it was faster than it's asthmatic sibling. A Nano was power limited which held it back to around Fury Pro performance levels, a water block couldn't change that.
When I bought the Nano (Jan 2016), FuryX was 50% more expensive and since I was using the Predator 360 it was still cheaper overall with the pre-filled block than buying the FuryX new.
It was with the stock tiny cooler and the single fan, that it wasn't getting the performance out, not the power. Clock for clock both cards were for same performance, if thermals weren't the issue.
Also both FuryX & Nano (only), saw a big increase in (8%) clock for clock performance with the April 2016 UEFI firmware AMD released, and higher overclocks on top.
Before that the Nano could do 1050/1000 after that 1100/1100. While the FuryX (second hand very cheap) got in November 2016, could do 1080/1050 with the stock BIOS and 1190/1100 with the UEFI. (again that was not a special modded bios, just AMD's own).
So the Nano was not that power limited as you think.
