It stroke my mind that during my 52500 km (~32500 miles) on my 2011 Ninja 250R i never noticed any sound from the cooling fan, ever.

These days several new temperature records were set throughout Norway (in Scandinavia), where temperatures got above 32 degrees C (90 degrees F).
Normally the air temperatures would probably help a lot in cooling down the engine at our latitudes.

The 250 has a temperature gauge instead of the fuel gauge found on many bikes.

Some times the engine temperature went to around 60 % of full scale, while it normally stays around an estimated 15 %. Think I must have shut off the engine from time to time, when it was at at least 40 % of full scale (temperature).

When does the fan normally "kick in"? Do you find it strange that I never heard the fan, taking into account that I'm far from deaf ? ;-)
Any simple way to check if the fan COULD possibly run, without letting the engine run hotter than what is "healthy" for it?

Thanks!
