DiabloII, your sorta getting the wrong idea about OC. All those fans you posted, where hideous. Those fans wouldent drop your temps yo. Those are all looks. Sorry to be so blunt, but those arent the fans your going to need. First, if you want a glowing fan, just get a grill.
Never get anything under 60mm fans. Stay with 80mm, or ideally 120mm fans. Myself, i dont own a single 80mm fan. I have 7 120m fans in my case. Im going to post a 80mm fan, witch will be a moderate fan.
Heres the 80mm.
Now if you want some real cooling, here are the 2 best 120mm fans on the market. Those are the ones i use.
Those other fans you origially posted, had around 20-CFM. Thats how much air gets pushed, the higher the better. Normal is around 50-CFM. The RPM, is obviously how fast the fan is spinning, witch also has alot to do with how much air gets blown. That 80mm fan i posted has 50-CFM.
The first 120mm fan i posted has 108-CFM, while the other has 125-CFM. So thats pretty insane, they do alot more work.
