Although be quiet! typically designs some exceptionally good products, it's also a 3 pipe 92mm fan class cooler, which I assume you're interested in over 120mm fan class coolers due to case clearance limitations. Regardless, the 3 pipe EKL Alpenföhn Sella and the 3 pipe be quiet! use the same problematic "push-pins" that Intel uses on their stock coolers to fasten the cooler to the motherboard without a "backplate".
Instead, the 4 pipe Cooler Master Hyper H410R RGB uses proper fastening hardware with a backplate to mount the cooler securely, whereas push-pins are notorious for being deceivingly tricky to get fully inserted completely through the motherboard and properly latched. Moreover, push-pins are plastic and are known to stretch over time, which compromises the mounting pressure of the cooler to the CPU.
Of the 3 choices you've offered in 92mm fan class coolers, I would still recommend the 4 pipe Cooler Master Hyper H410R RGB with a backplate over 3 pipe coolers with push-pins.
