From the video description:
“We interviewed one of Noctua’s technical team members (Jakob Dellinger) to discuss the challenges and troubles of focusing entirely on performance for a cooling product. This video goes over fan behaviors like tensile strength, endurance, aging, creep, and cooling characteristics like blade tip distance from the frame and blade passing harmonics. The video is a surprisingly transparent insight into what Noctua has been dealing with for 8 years now as it has attempted to reinvent its most popular product, and the company now thinks it has an NH-D15 Gen2 and “Next Gen Fan” nearly ready for primetime.”
Exactly why I went for a custom loop after years of saying I’d never put water in my system. Now my GPU is cooled by the same fans as the rest.
I’m not certain, but I might have gotten lucky with just how silent the pump I got was (a low noise oriented DDC from EK – can’t remember the exact model right now).
