Well, maybe you haven't finished the first draft yet.
What kind of editing ideas are popping up? The "cooling phase" is used to get a fresh look on your manuscript, so you are able to find wholes in the story, more spelling mistakes you would have missed otherwise, passages that do not read fluently and so on.
But if your ideas are about changing the story, adding a scene or two, asking "should she really kiss him in chapter five", then it could be that you put "The End" on a not yet finished story.
(Besides that, keep in mind, that this cooling phase works for a lot of writers, but that does not mean it is the right tool for you.)
Nevertheless, you need to get your head free of this stuff. As a writer to get your head free you have to write it down. You do not need to change anything on your first draft, just take a piece of paper or a text file and note down what you want to do. The thing is, that you also have a lot of garbage in your head, and you have to note that down too, to get it out. Otherwise there is no room for the good stuff.
So, I advise you to just note down your ideas and wait a little bit longer. In two days if you look on your notes and say "I have to implement that to the story" then do it. If it is "Why have I ever thought this is important?" then don't.
I forgot to mention, that starting a new project is also a good idea. Then you have something different to think about and can the other draft rest. Not to mention, if you really want to be a writer, you should write. Which means, start a new project.
(Oh, and congrats for finishing your novel.)
