I was having having the same "problem" with mine.  Whenever I stayed at around 
140/150kph, the gauge always went above the halfway mark.  Per my mechanic, 
the fan switch isn't working properly, the fan does come on but not at 
"highspeed".  He's changing the switch right now actually, hope *it* was the 
problem.  The switch itself doesn't cost a lot, Can$12.  It's a fair bit of 
work tho, as I beleive the rad needs to be removed. (?)
