Thx all I get the lay of the land now
For now I'm going to forget about the cpu fan and see how that goes temperature wise.
If need be I can go with a 4 wire case fan and use existing header for cpu fan and then drive case fan with something like this https://goo.gl/izUx2V or use pwm from the gpio header which will give me control via os.
