Noctua isn’t alone in the premium performance fan department anymore. Phanteks t30 and the new be quiet silent wings.

Personally I like the phanteks t30 they sport a slightly wider blade than traditional 120mm fans, so they’re already cheating the competition a little but at the end of the day they push more air but with their design they might not fit every application particularly in some cpu coolers where you might have a fan sandwiched in between two radiators. The fans themselves are of a much tighter tolerance than you’ll find in just about any ABS fan, glass fibre reinforced material is very recognizable across all three of the aforementioned manufacturers in their premium line and it has less play than ABS which you might find in an RGB fan. Both phanteks and be quiet have 3000rpm models a feature which is obtrusively loud to use but a nice to have just in case you ever repurpose your fans for anything else like making your own little server room or a drying cabinet, while the ceiling of 3000rpm is completely impractical for daily use I find my t30’s do hit a nice balance at 1800-2000rpm in my closed case with noise comparable to my old Corsair fans clapped out at 1400rpm while also pushing more air even if the rpm’s were even.
