Are you using cura 2.X or 15.x? The newer versions of cura have the infill at a higher speed. I completely disagree with this philosophy. I'm guessing your infill is much faster than 70mm/sec.
Anyway, what type of printer do you have? Please update your profile settings. 70mm/sec at 200C at .15mm layers is much too fast for a um2. I'm guessing this is a um3?
Speed and temp are related. The faster you print the more heat you need. I'm sure @gr5 will copy paste a very old temp/speed table from um2 (not plus) ratios. Something like this https://ultimaker.com/en/community/16573-printing-speed#reply-111348
