Hi everyone,

I’m trying to fine-tune my fan settings for a quieter system while still keeping good thermals. I’d really appreciate if someone could share their fan curves or recommendations.

My setup:

• Case: DeepCool MATREXX 55 V3 ADD-RGB 3F
• Front intake: 3 stock DeepCool case fans
• Rear exhaust: 1× ARCTIC P12 Pro PST CO
• Top: ARCTIC Liquid Freezer III Pro 240 (AIO, exhaust) (on the top side)
• GPU: NVIDIA RTX 4070 TUF Gaming
• CPU: AMD Ryzen 5 5600X (6-core)

What I’m aiming for:

• As quiet as possible during idle / light usage
• Stable temperatures under gaming load (not chasing max OC, just stability)
• Avoid aggressive fan ramping / sudden noise spikes

Questions:

• What fan curve do you recommend for the AIO pump + radiator fans?
• Should the rear exhaust be kept very low RPM or follow GPU/CPU temps?
• Any BIOS or software settings you’d suggest for smoothing fan response?
• Is it better to prioritize case airflow or let the AIO handle most of the thermal load?

If anyone with a similar setup could share their curves (BIOS screenshots or %/°C values), that would be really helpful.

At the moment my setup on fan control looks like this:

Also, one more thing I noticed that I’m not sure is normal:

I had to disable the Smart Mode in the BIOS for the AIO fans because otherwise it kept interfering and made the fans ramp up for no reason, even after I adjusted the curve there. Now it always starts at 100% until FanControl takes over. Is this bad, and is there no other way?

Please be kind; I only started dealing with this yesterday.
