68-70F is about ideal for US-05 in an IPA. But she can go a few degrees higher or lower with also very good results.
Even with your Brew Jacket, try to keep your fermenter temps as steady as possible, within +/- 1-2 °F, if possible. A sudden drop in temps (such as overnight) can stall the yeast, making it much harder for her to resume, and finish the job.
So, try to find a place/area that can best provide that kind of evenness in temps.
During the main part of "active" fermentation, where sugars are being converted into alcohol and CO2, heat is being generated, so some cooling may be needed.
Before and after the "big event," you may need to add some (extra) heat to keep temps in range and steady. Especially when ambient temps are lower.
Raising the temps somewhat toward the end of fermentation will help the yeast stay active to finish and clean up.
