I was curious, as I have seen some tapes that said OK for GPU, RAM, etc, but said specifically not OK for CPU. I am unfamiliar with the tape you listed. If you have used it for CPUs before, should be OK, I would think.
You may already know that Khadas has a fan kit for the Vim, in case you want to keep small and tidy. 
You may also want to consider this when choosing a heatsink.
Hope you get it resolved.
Note: I do not have these accessories.
