1600SC rear fan too fast

I've noticed the rear fan in my 1600SC seems to be running much faster
than usual, though I don't have logs to know what the baseline is.
Here's the sensor output (using OpenManage Linux kernel plugin)
Front FAN RPM = 1721 RPM
Rear FAN RPM = 3375 RPM
CPU 1 FAN RPM = 3125 RPM
CPU 2 FAN RPM = 3183 RPM
CPU 1 Temp = 87.8 F
CPU 2 Temp = 84.2 F
Planar Temp = 82.4 F
The server is rarely under any load and the planar temp has kept
pretty constant... so it seems to be running abnormally fast. I
recently shut the server down and cleared the little bit of dust that
has collected, but no change in fan speed. The server has a single
power supply and the case is fully closed.
First, is the fan actually running fast... should I worry about it
failing? Second, what can I do to troubleshoot?
