Can you use FanXpert 2 on, say, a P8Z77-M? What I mean is, is it just a question of the right software or are you stuck with FanXpert+ on that mb?
I tried Fan Xpert 2 on the P8Z77-M Pro for a few days, but reverted back to Fan Xpert+ because I didn't like the results. My case fans use 3-pin connectors, so when I replace them with new PWM fans, I'll give Xpert 2 another go.
What were the results that you didn't like?
There seems to be a lot of conflicting information about Fan Xpert+ and Fan Xpert 2. Do you mean to say that Fan Xpert+ cannot do voltage control of 3-pin fans?
Fan Xpert 2 was giving me crazy test results. All three case fans were showing vastly different numbers at high percentages. For example, one fan was showing 1158 RPM at 90% and another was showing 878 RPM. Also, the three standard Asus fan settings in Xpert 2 were not my cup of tea. All the fans were the same make / model.
I recently installed three Scythe PWM fans and gave Xpert 2 another try and was very impressed. My story may just be an anomaly, but I wasn't happy with Xpert 2 when using 3-pin connectors. I'm very happy and impressed with it now that I have PWM fans.
