Issues with the fan curve affect performance and efficiency.
Issues with the fan curve affect performance and efficiency.
Hello, your AIO fans are fluctuating during gaming or browsing. You've adjusted the fan curve and timings but still see issues. Checking your BIOS settings on the attached image might help. For your system (13900k, Arctic Liquid Freezer II 420 AIO), consider MSI Z790 Tomahawk support. Let me know if you need more guidance.
Get FanControl from @Rem0o – simpler, more user-friendly software that works without needing a restart or BIOS setup. Adjust settings instantly.
I agree, you're not mistaken. The software is much more user-friendly, and being able to adjust things on the spot avoids the hassle of restarting. I also think percentages are simpler to manage than dealing with step-up and step-down timings. That's why I suggested it as part of a solution to address the problem mentioned.
Thanks for your feedback! The step-up time is already at its limit. I’m unsure why 0.7 is the maximum value. Asus offers a fan smoothing feature, but in this MSI BIOS there isn’t anything comparable besides the step-up time setting. You might want to adjust the curve near the peak of the thermal profile. Since you connected it to the pump header instead of the CPU, it’s not causing any issues. This approach should help you avoid extra background software. I hope you can get it working in BIOS—your preference for a clean setup is clear!
Consider placing the pump in the header and keep it running at full capacity. For fans, opt for a low-speed idle around 40% to minimize noise during acceleration. Avoid sudden jumps from 0 to 20%, then 30%, etc.; instead, start increasing gradually from about 50°C. Once reaching higher temperatures, apply speed changes in steps of 15–20°C. The maximum speed should match your CPU's thermal limits, which for a 13900K suggests keeping it between 90–95%. I also recommend using FanControl since the BIOS interface is quite poor.
For my AIO the pump and fans are merged into a single header. Changing it would require a complete overhaul, which I don’t want to do.
Did you connect the pump and fans to the same header using a splitter? That’s not recommended—it can cause high current on one line. Since the pump uses a 3-pin PWM, it’s not adjustable anyway.
