Hi, I'm going to buy a fan, but I'm not sure whether to buy the Cougar Vortex or Cougar CFD.
The thing is, the cfd says that it works by HB while the Vortex by Hyper-Spin. Sincerely, I don't know what HB stands for, I suppose is Hydraulic Bearing or sth like that, but I don't understand how it works neither.
If someone could help me I'll be very grateful.
