need help choosing a 92mm cooling fan for my rad



i will keep it in mind thanks

 
The Delta fans are usually good. Delta has been making fans and power supplies for, maybe, longer than just about anybody else in the business. And I suppose if this unit is a server in a location where nobody will have to listen to it then this one would be a good choice due to it's high CFM and dual ball bearing design.

However, be aware that the decibel level is TWICE that of the Noctua fan I linked, plus another 8db on top of that. Ball bearings, while being very long lived, are also tremendously noisy versus the sleeve, rifle and fluid dynamic bearings used on most consumer PC cooling fans. So if it's going in a desktop or workstation, the Noctua would be a much better choice and is around the same price.
