Mitsubishi Carisma - Cooling Fan - mark193

Hi all

My cooling fan been running now and then during the colder weather recently, usually when the air-con is on.Is this to keep the air-con 'bits' cool with it running so much ?

The temp gauge sits plum in the middle as it's always done.

No loss of coolant - car runs great - mpg OK - compressor kicks in and out as it should (is that right?) as the RPM'S rise and fall when I'm sat at lights etc -

Any advice would be welcome
