FAQ
What cooler type is essential?
A high-performance 420mm AIO liquid cooler or a custom water loop is absolutely mandatory for this CPU's thermal demands
Can I use air cooling?
No, air cooling is insufficient for the Threadripper 9970X. It will severely throttle under any significant load
Is case airflow important?
Absolutely. Excellent case airflow is crucial to help your liquid cooler dissipate heat effectively and maintain optimal performance
