problem with CPU fan showing 0 RPM

[sudeki300]

i have just finished installing windows 7 on my new titan xenomorph, but now i get a green box in the bottom left hand corner telling me that the CPU fan is running at 0 RPM. when i look in the asus pc suite it shows the fan spinning at around 796 rpm's then it will suddenly go red and show 0 again. i have tried to update my bios but the problem is still there. i took the side off the pc case and the fan on the CPU heatsink never stopped spinning even when the message was on screen telling me that it was not spinning. this is also for the chassis fan, that always shows 0 RPM. is it possible that the sensor have come loose in transit and juts need to be replugged. i'm just nervous as this is my first ever big purchase on a pc tower and just want nothing to go wrong. thanks........................sudeki300

thanks to everyone for their replies. i'm using the asus suite II, it guess it will do no harm to select it to ignore the fan RPM. just saves getting the message on the screen every few mintues....................sudeki300
