Why don't you first try it out with just the single fan?

Unless you are already having thermal problems the 1 fan might be all you need.

it's thermal throttling

If its thermal throttling then you might want to check the thermal paste application. The U12S is a very good cooler and should work well enough to cool a stock 10900k. Worst case scenario you should buy an identical fan to the one on the other side of the cooler. https://www.amazon.com/Noctua-NF-F12-PWM-4-Pin-Premium/dp/B00650P2ZC. Also make sure that the fan direction is correct. Always troubleshoot before buying something new.

Temps? Voltages? Are you running everything stock? Adding 2nd fan doesn't improve things so dramatically that it would help. But
if you want to try, any 120mm fan works. So one of your cade fans?
