The slim fan should be fine. A part of the shrouding for the AC condensor fan needs to be cut for the wastegate to have room and the main AC line that runs between the fans needs to be bent out of the way. So, yes, I am still using the stock fan and I just had to cut a little part out of it.

Also, I forgot that the upper bracket that holds the radiator on needs to have a little part cut out where the screw goes in so that it can be pulled back a little bit.
