If you have the Wraith Prism, its quite good actually. However a new tower cooler will be much more efficient.
The 120mm Fan (or fans if you buy one with two) its much larger and the airflow is better since its not downfiring like the Prism. You'll lose a bit of airflow on the VRM but its not that bad.
You can also try offset undervolting a bit on the vCore.
Good Luck
