It looks like you are getting a temperature reading for your CPU, so that isn't a problem... what you're apparently missing is the plug from your CPU fan to go onto the motherboard. That allows monitoring of the fan's RPM speed. If your fan didn't come with such a connector (it's a multi-colored wire coming from your heat sink, with a small plug at the end), that strikes me as quite strange... but it's ok if you don't mind being unable to monitor your fan speed.
