I would like a second opinion on whether this is a noise that I should be concerned about.

I was troubleshooting an overheating problem, my engine never busted the max temp, but it would get pretty close from time to time.
Turns out my e-fans were blowing the wrong way, and I'm an idiot. So I reversed current flow through them and they are corrected now.
I took my car for a test drive to see if that fixed my heating issue, and it did (yay) but then I pulled into my garage and my engine started making a clicking noise while it idled.
Edit: If I need to take a better video just tell me
