SFF21F will give nice performance if you decrease the input voltage (from 12v to 5/7v).
But of course Scythe KAZE-JYUNI is better than SFF series (SY1225SL12L, 800rpm but with 40,17CFM), but it is only available in 團購專區...
Also for NoiseBlocker, it is the best of all, but very expensive.
BTW, Some quiet fans are very delicate, and very vulnerable to shocks...So buying fans abroad is of some risk. |
