Sifus...want to ask: I'm using centurion c-5 that comes with 120mm CM fan (1200rpm with around 40cfm, i think), but i decided to change the fan with better "ump" to evercool 120mm fan with 2000rpm & claimed 70cfm...so will this fan give better airflow? BTW i also added evercool PCI fan...

there is something i want to ask...

I bought a 120mm evercool case fan as rear fan while the stock 120mm CM fan (that comes with the C5 casing) i put it in between 5" bay to use as intake fan...however i realized that the RPM for the CM fan is slower compare when it is used as rear exhaust fan...the CM fan was spinning around 1200rpm (when used as rear exhaust fan) now only spinning around 800rpm (front intake fan)...I connect the CM 3-pin to the mobo directly, @ 4-pin that says "sys_fan"...can anyone know why the rpm is slower? I don't think stock 120mm CM fan have thermal sensor...

if I connect directly to power supply, will the 120mm CM fan spin at max rpm?

thanks, I'll try to connect the fan direct to the PSU...
