hello guys i need some help here about a silent fans. I need to replace the fans of my case lian li pc 50 r because they have the freaking red led on all the time. i was thinking to a way to turn them off but the only thing that come in my mind is to cut the led loose! lol So i thought that probably the only way is to buy 4 new fans. i heard that noctua are the best in silent fans. What do you suggest? this is my fans configuration now: -2 x 140 mm 1000 rpm on top of the case. -1 x 120 mm 1200 rpm front case. -1 x 120 mm 1500 rpm back case.
