2 lesser cfm in push/pull or leave stock?

post #1 of 4
Thread Starter 
so i just bought 5 of these from a fellow OCN'er (couldnt resist the price )
Lian Li LI121225BL-4 120mm Black Case Fan, 3-Pin Regulator Connectors.
# Speed: 1500 RPM
# Airflow: 56 CFM
# Noise: 24.7 dBA
# Power: 3.24 W

i plan on adding 2 to the bottom of my sig rig as intake, one on top next to the stock 140mm as exhaust, and was thinking about removing the Slip Stream 120 PWM that came with my cooler and adding the remaining 2 for a push/pull since i read you dont really want to mix and match fans in a push/pull config. my question is, would i see any better temps with two 56 cfm fans in push/pull or should i leave the stock 74.25 cfm sycthe?

The cfm is'nt amazingly important for a heatsink or radiator,you need to find out which have higher static pressure.The more static pressure the greater the force of which the air passes through the fins,hence better cooling.

Ehume informed me that the Lian Li are garbage. I was close to buying it from him, but the prices/performance of the Yate Loons were too tempting.
