Default Re: Engine Temperature

I run hot when on trail... I've noticed it seems to be a combination of fan CFM and water pump rate. If I sit at idle in 100 weather the gauge will creep upwards toward the red zone... If I run the engine at around 2K rpm, in neutral, the temp comes down. Does the fan run faster at higher RPM??? or is it constant RPM??? I know the water pump runs faster pushing more coolant thru radiator... It's never overheated but you can tell that it's damn hot. Wonder if higher CFM electric fan on other side of radiator would help...
