FAQ
Should I choose an AIO or custom loop?
For this CPU, a robust 360mm+ AIO is minimum. Custom loops offer superior performance and aesthetics
What radiator size is recommended?
A 360mm or 420mm radiator is highly recommended for sustained performance and thermal headroom
Can I use air cooling for this CPU?
Air cooling is strongly discouraged. This CPU requires advanced liquid cooling to prevent throttling and ensure stability
