Summary

The CR-200B has two fans doing basically one one job. Replace both the 5015 radial and 4020 axial inside the case with a 12V 120mm axial. I mounted pushing air out the bottom so less chance for cool air to introduce into the printing chamber. If you have a decent 120mm fan, it should have enough CFM to pull the heat out.
