Those speeds look more correct -- guessing now that #1 and #2 are your 200s, #3 is the 120, and #4 is the 230. I'm wondering now if you were in Silent mode starting out.
I have mine on the Standard profile with PWM enabled, and the 200s here spin at about 350-400, just for a point of reference. Still unnoticable under the CPU and GPU fans as far as sound goes.
