I need to know about fan brands b/c I KNOW NOTZINK

[SirDennis]

I'm planning on getting some fans to fill up the holes on my case. What are the advantages and disadvantages of all the fans out there?

There are different answers to your question. It depends on what is more important to you, i.e. flow rate vs. noise level. The higher quality fans will tend to be ball bearing because they have a longer lifespan than sleeve bearing fans. From my research Panaflo fans are ultra quiet and high performing. I've also used Sunon fans and find them to be quiet and reliable. If you're concerned with noise try the listening room (http://www.sidewindercomputers.com/tecar.html) so you can hear what different types of fans sound like. It also lists the important details like flow rate (cfm) and noise level (dBA).
