For 35 USD a fan, I could buy an equivalent number of proper server-grade fans, a frequency-selectable PWM controller, and some 18 AWG wiring and still come out on ahead on cost and performance. Or just get some Phanteks T-30s that are still slightly cheaper in both single and triple packs.
But again to be fair to Corsair, kudos for bringing in another stator vane fan into the 25mm consumer market space. I'm interested in their pure airflow and airflow in pull config behind a filter performance, where the stator vanes would theoretically shine in focusing and throwing the air further. I'd also like to see what Noctua, Be Quiet, or Phanteks could do with stator vanes, or if Silverstone would modernize their Air Penetrator line with stronger performance.
