Do you have it on a switch.

 

At the moment I just plug the power into a constant live before I drive.

I'm thinking of wiring it into an ignition live rather than getting a switch that you need to plum into your water works so it picks up the temp and tells the fan to come on.

 

What's the harm in having the fan on constantly while the engines running as opposed to just when it gets hot ?

Personally if it's an effective fan, i would possibly suggest almost over cool things. certainly longer to heat up to operating temps.

Minimum temp for effectiveness is around 70 odd degrees, i think about 75.

The electric sub fan kicks in at 95degrees. with a koyo,slam panel and efficient cooling system you should be running around 80 degrees.

I have a Spal electric cut in switch which kicks in at 85degrees, though nowt else is fitted yet :D you can buy these on ebay, from spal online shop or maybe ask Luke to sell you just the electrical side of his kit.

IIRC most electric fans are NOT reccomended for continuous use. IMO You need a thermostatic switch in the system
