They are supposed to speed up when the temperature goes up and then slow down when the temp goes down to lower the noise level.  No reason to expect the speed to be constant.

Monitor your CPU temperatures and see what they are.   Various utils exist like Speedfan  http://www.almico.com/speedfan.php to do this and see what the CPU temp is.  Is it higher than normal as Dr Klahn suggest or is it normal and there could another problem.
