CPU overheating due to new GPU

I recently upgraded my graphics card from a GTX 1070 to a GTX 2070 Super. In doing this, my CPU is reaching temps of 70 degrees C when I game. As soon as I noticed that this was happening, I’ve stopped gaming until I can figure out the problem. I understand that the new GPU is pulling too much power causing the CPU to overheat, but what can I do to solve this?
My CPU is a Intel Core i7 7700
My GPU is a EVGA GTX 2070 Super
Cooling system is a basic water-cooling system that came pre-installed to the PC.
