One thing I will say is that while the new NH-D15 will likely have the best performance out of the air coolers, I think it kinda looks ugly compared to the Deep Cool offerings.
I'll be interested to see the performance differences between them tho but I wish Noctua put in more effort to the aesthetics of their flagship cooler.
