bought mine with impulse. 1st batch user for Malaysia/Asia. so far is ok. no problemo.
but my friend did report his unit fan is a bit louder when we both played the same game. he bought used unit. maybe lemon unit 
now I prefer to play all my multiplatform non mp focus game on X rather than my Pro. coz the Pro is effing loud coz of the none liquid/vapor chamber cooling.
Tested it with MHW for both on Graphic mode
