I understand that u can play a pwm 4pin fan to a regular 3pin slot...but if i do that does that mean my pwm fan will run at full rpm at all time?
 
Solution
yes and yes. the 4th wire basically controls the power pulse length. remove the wire and you remove that control so the fan will only spin at full speed.
