Installed Asus PC Probe v2.14.01 and it didn't sense my Sunon case fan connected to my P4T fan header. Un-installed v2.14.01 and installed v.2.14.04. Version 2.14.04 sensed the fan but had a problem with it because it was spinning at 2087 RPM and that is below the 2200 RPM minimum. There was no way to lower the 2200 RPM minimum so the silly thing just kept beeping until I had it stop monitor that fan (which defeats the whole purpose). PC Probe also doesn't like monitor settings of 1024x768 with large fonts. I guess it's MBM 5.08 for me! Overall temp readings where just about the same.
