Well, the general opinion that swayed from "The chip will burn" to "fine with any cooler" is quite extreme :- )
Of course the chip won't burn but throttle but performance difference won't be minimal at all in multi-threaded performance.
There is big difference in general use (games, media) where few cores can clock very high leaving the rest docked or clocked lower and thus maintain high performance (FPS,etc..) despite overall throttling, but mixed workflow like Corona Interactive will suffer lot more.
Powerful cooler is always good idea and there is reason why coolers are rated for some particular TDP (Noctua has the best publicly available list of this).
Even when you power limit (or/at same time voltage limit) keeping the CPU well cooled maximizes your performance. You paid a lot of money to leave it on the table.
Reason to avoid Enermax is because they have the highest fault-rate in industry. If you have 3000 USD PC, you don't want your liquid cooler to grow shit inside, lean or just explode the pump outright.
They simply produce crap products, it's that simple.
