removing radiator cooling fan

I don't know if this is considered an add on, or a take off, but I removed my fan off my nissan 4x4 pickup last year and added an electric fan. I have found I rarely have to use the electric fan unless I am doing a lot of idling, which I try not to do anyway. the truck comes stock with a 160 degree thermostat. I might even consider swithching to a 180 degree thermostat since the truck runs so cold even without a fan. If I switch thermostats, I will probably switch to evans waterless coolant. I run it in all my diesel powered rigs, and like the protection it gives at higher temps.
