Hi,

I have problem with 2 Cooler Master Jetflo 120 fans noise. First fan is connected with 4 pin to motherboard and I set it to silent option in BIOS but this fan is still loud although it runs at 1100 rpm. Second fan is connected with 3 pin 1200 rpm silent adapter to motherboard (because I don't have one more 4 pin on motherboard) and it is still loud as the first fan. I tried to reduce first fan with programs but it didn't change anything. Can somebody help me to reduce loud fan noise?

Second fan with 3 pin 1200 rpm adapter is slightly noisy from first fan but if I find solution how to reduce first fan speed I will buy cable spliter.
