CPU Fan Going Crazy After New GPU

[Asherim]

I recently upgraded my graphics card at the advice of another member here from a GTX 660 to a GTX 970, while it has vastly improved my performance, my CPU fan now will run louder and faster than ever before if I open up any games, even if they're on the same low settings that the 660 could run no problem. I looked into SpeedFan but I'm still fairly new to it, so now it spikes for about 5-10 seconds of really high RPMs then goes back down to nearly nothing. From what I can tell my temperatures aren't even super high or anything, usually hanging around 60's in heavy load situations and maxing out at 70 or so. Any explanation or help would be appreciated.

Stock fan is the problem, the FX series had garbage stock fans.

Hyper 212 evo, Cryorig H7 are good replacements.
