With the new thermal design of Zen4 I thought I would test something that at first seemed counter intuitive but has worked well over the past 3 days.
In the bios of my x670e-e Strix board I set the Q-Fan profile to custom and held fan speeds to 30% until the CPU reached 80c when I pushed to 70% and finally 100% at 95c.
I’ve had much less oscillation with my normal idle temps at 42c and generally I see the CPU push to the mid 60s when launching a heavy app like photoshop. This is certainly a different take than prior builds that included fan tuning with the goal of offsetting heat production vs soaking heat to a known and accepted thermal maximum.
This build may move to my Phanteks Evolv-X and if so I will certainly move to a 420mm AIO with the hopes of near silent operation until the 80c mark.
