We'd need a lot more information on what material, temp, speed, kind of fan used, etc etc to be able to help you here, but sure you can try slowing down to see if that affects it.

better than CFD or water dish tests is an actual print test, such as the Shuriken D85. Chirpy has a good writeup on it. https://github.com/chirpy2605/voron/tree/5937508fad2eead9a7e3a68b8d60f6e527e56548/general/Duct_Testing the important thing to do on htis test is to get your print time under...
