Pros: Great performance, aesthetically appealing to the eyes.
If you get these fans for a radiator, I suggest also getting a fan shroud, that will reduce some of the noise and improve performance even more so. If you just want to use them to push air in/out of the case, if that is your thing, sure, overpowered.
The amount of air it moves is just outrageous! Do you even need fans this strong? At top speed, it was pushing a gale of wind through a radiator, as if the radiator wasn't even there. Totally overkill!
But the noise! If you think one is noisy, try 4 of them at top speed. I was reminded of the engine room of a container ship when it's at idle in a dock. If you don't know what I am talking about, go YouTube it. The container ships when they move around with their engine running, you can speak words, and nobody will hear it; in fact the sound level is deafening literally. But at least when the engine is idle, you can shout and somebody actually hear you. I don't think these fans are that bad, but honestly if you try and game with 4 of them roaring next to you, you will probably feel like you are gaming in the engine room, next to an idle diesel engine for a container ship. Of course if you have nothing impeding the movement of air out of these things, then it's not going to make as much noise, obviously low turbulence of air.
I recommend you have a method to control the speed, so you can change between performance and silent mode. I got a fan control box to tame this beast, and I think you should too!
