Probably what is happening is that the high speed is coming on and not
the low speed.  Does it sound really loud when it comes on?  If the high
speed only comes on then it is allowing the radiator to get hotter than
it should and the fan will come and and go off more frequently than if
the low speed is there.  This problem is usually caused by the radiator
fan resistor going bad.  I have these in stock if you find you need
one.  There is a write up here about how to test your speeds:

It is a simple test that takes about 5 mins to perform and will tell you
what is going on.

Hope this helps,
