I understand that only the BX series of panaflos supports RPM monitoring, however, I didn't get one. So, now that I have CPU fan RPM monitoring disabled in the bios, do I just leave it be? Can I hook up my CPU fan to a fan controller? What are your thoughts?

Yup! Just disable RPM monitoring and go. That's what I did. RPM monitoring is a joke anyways when you have a fan controller (well I guess if you get an expensive one, it's good to have, but when you get a cheap one like mine then all you get is knobs).

Here's an interesting thought, confirmed through personal experience.

Some fans -- such as that which you mentioned -- do not come equipped with speed monitoring (the yellow wire).

Yet, connecting such a fan to the CPU_FAN header of your motherboard will still allow you to vary the speed with software like SpeedFan. Speedfan allows you to set the minimum fan speed at a percentage of the maximum value. If the maximum value is accurately reported by the manufacturer of a fan without rpm monitoring, setting the minimum value with SpeedFan simply changes the voltage or pulse-width-modulation of voltage, and you should be comfortable knowing the approximate minimum fan-speed setting by multiplying the chosen percentage value by the rated maximum fan-speed.

I basically agree, but monitoring the speed of a CPU fan is not exactly a joke. I appreciate the BIOS refusing to allow the computer to POST if it detects no rotation of that fan. If I disable that feature, my CPU might get dangerously hot before it turned itself off.
