140mm ka... macam pernah see before in garage sales lol...

iirc it shud produce around 50cfm and the brand is evercool .... lol

Actually I don't really mind about the LEDs, I just want a good fan hehe..
I'm also not a silent freak..a lil noise is okay..hahaha

What amount of CFM is considered good? 50 CFM and above?

personally i will take some mid cfm fan of around 50-70 cfm rating for my casing and also heatsink lol....

this way i can keep it silent and yet good enuf to cool things down ....

from what i remember, vizo led fan at 70cfm is already audible....

for the 140mm fan i plan to get the cm 140mm blue led 1.yeah crap leds but no choice,or any1 here can recommend similar 1 with longer lasting leds and with same or better cfm.

and how should i place the 140mm on the top of my cm690?blow in or out?here's a estimate pic of my case fan set up

top exhaust, rear exhaust, front intake, bottom intake
