if 5 min is your judge, I don't think it is an issue. the wires do come seperatly, and maybe feets will join in and look them up.
I have the controler on mine set a bit low. so I know it runs flat out the entier time the car is warm enough to fire it up. I also had without a controler where it just ran flat out the whole time the car is on. never had an issue. now I probably haven't kept the car running more than an hour or 2 at a time as I haven't taken it cross country or anything.
I also compared the wiring to an r-class and it seemed to be the same.
Sorry I was not completely clear in my post, I have not run it much past five minutes preferring to not tempt fate as I was unsure if the cabling will get hotter.
I am going out today to run the fan flat out by using the excellent disconnected sensor facility the PWM has.
If 'feets' has anything to add it would be appreciated.
