M5A97 LE R2.0

I just went back to the manual. My MBs do not support voltage contol....no way to do that1

Forgive me, I am not sure I understand. You have the same MB and 3 pin fans as I do. How are you controlling the 3 pin fans? Is it just with the software or are you using a circuit? Finally, at 2,000 RPM, how fast do you think my 120s will go? @dmax Forgive me, maybe you did not understand...

With 60 percent duty cycle, do you know how much they will slow down from 2,000 rpm? The motherboards I have use 4 pin PWM control. As I understand, 2 lead fans simply run on 12 v. What you are refering to is the inertia, the startup volaage could be around 5 v plus or minus a volt or two...

I have been able to control 3 pin fans by decreasing the voltage with resistance. I assume you are talking about 4 pin fans. It was my understanding that the fans are the same in terms of their being simple DC motors, just that the PWM fans' speed is controlled by duty cycle. They have a PWM...

I have a bunch of M5A97 MBs LE and non LE R2.0 with AMD processors. I am new at doing PC builds and I bought a bunch of coolermaster led 120s that run a 2000 rpm. I want to run 4 fans intake and 3 fans exhaust. These are 3 pin fans. I have heard but am not certain, that the PWM MB control in...
