You didn't state which Lian Li case you have. However, you did state you have 4 fans. I'll assume you have the stock 80mm ADDA fans. They supposedly flow about 35cfm each. I'm also guessing you have 2 fans in front and either 1 exhaust and 1 blowhole or 2 exhaust fans. Here's my choice if noise is no issue:
It's the 80x80x38mm Vantec Tornado fan. 5700rpm 84cfm and a loud 55dBa
You don't have to buy the fans here. I just used the web site as an example.
You can not use the motherboard for power. The fans pull too much watts/amps! (9.1w/.76amps)
You might also consider a fan control option. I had one of these and it was really loud and 4 of them will get good air flow, but keep the neighbors up!
I hope this helped, :-)
