I have a question though. When I power up this new unit with the paperclip trick, the fan in the psu kicks up then slows down and eventually stops. Is this normal? Are the fans on the new corsair PSU's pwm and adjust speed as cooling is needed?

Sounds like it. Does the unit continue to run and continue to deliver power? I know my older tx 750 continues to run the fan after shutdown if it's particularly hot.

Current-generation Corsair GS, TX, HX, AX, AX-i all shut the fan off for low loads.

I don't think it's PWM-controlled, but just direct voltage controlled. Most PSUs don't bother with PWM fans and just run less than 12V on the fan on a 12V-nominal fan, for most loads, like the old power supply you had. These new ones from Corsair just turn the voltage down all the way (or at least enough) to stop the fan on low loads, like some others from other brands these days.

There were probably enough users complaining about noise on GS / TX / HX for them to make this switch.
