It will run significantly hotter, which will likely lead to premature failure.
Often these pumps are noisy because the run too hot, the impeller gets warped from the heat and becomes unbalanced. This is why some people will say their quiet one is quiet and others will say the opposite.
You've created a temporary solution to reduce vibration noise but it may cause bigger problems than it has solved.

+1 Looks like that pump has a wetsuit on. LOL
Just make sure you have a back up ready when it fails. Love the DIY
