Can I reposition an already placed CPU cooler? [urgent]

I’m putting my new pc together and I think I put the Freezer Pro 7 aftermarket cpu cooler facing the wrong direction. Since nothing is in the case so not connected, can I just remove and rotate the cooler and put it back on again? Or will this mess up the paste that’s on the cooler? The paste already came applied to the cooler. I assume since it hasn’t melted since it’s not connected, I can just remove and replace without cleaning out any paste?
