It really shouldn't matter as long as the solder joint is still good and the capacitor itself is not damaged in any way. Put it through a pretty good battery of stress tests to try and suss out any issues, and then you can go from there. If you run into issues, you can work with the reseller you bought it from if you're within their return period, otherwise I should be able to set up an RMA for you.
If I'm gonna do an RMA. Do I need to return the MOBO first?
I tried to test the CPU using OCCT for 2hrs. The highest temp it registered is 80C. And IDLE is about 40. Is that normal?
Although I haven't encountered any restarts yet.
