GMT800 vs GMT900 Electric Fans
Does anybody know of a difference between the generations of fans? I know there is 2 difference motor setups. 500 and 700 watt I think it is.
But the GMT900 are PWM controlled where GMT800 are a single speed but controlled by a Series/Parallel relay setup.
Setting up a couple turbo trucks and going to try the Dorman 902-310 SSR on them and ive got a set of 2006 fans to test them on.
Wondering if they changed the motors for PWM or are they the same?

Other than blade differences I do not know any difference.

The GMT 900 fans are pwm? I didn't know that. Well, I don't much about the 900s. 🫣
So since they are pwm, are they like variable speed then? I'm thinking of how the alternators that are pwm controlled from the ECU...
