Using the in-camera noise reduction options on the 7D is a PIA. It slows the camera down. Turn them off and use a good NR program like Neat Image or Noise Ninja. Use the lowest ISO you can. Shooting RAW for long exposure pics can be great because post editing them in a program like CSraw can kill alot of noise automatically.

The in camera noise reduction only affects exposure that that 1 second and longer. It doesn't affect if the exposure is 0.9 sec or less. Page 208 of the Canon 7D v2 manual. It does it by taking a second exposure to measure the noise and read the differences between the 2 frames to save only one frame - most of the noise.

I have no experience with Neat Image, but Noise Ninja is not great because it needs a Canon 7D profile and NN has not been updating in a long time. They are concentrating on Photo Ninja as an alternative to Lightroom w/o the DAM.
