Dps to Hot need help

Have a 2010 650 and ride 90% of the time on the min setting but when in slow technical stuff or just working in the yard the motor gets very hot and causes the check DPS light to come on this is the only issue I have with this machine. Have been reading about people putting a new fan controller on causing the fan to come on more often I’m considering going that root. I’ve also read about people removing the inner fender plastics allowing the dps unit to breath more does that really work? If so why are the new 650 g2 all closed up with plastics and have no issues? What should I do to fix this. Machine itself never has overheated just check dps light has come on. Turn bike off then on and it’s cleared for about 5 min light comes back
