Question about Fan Curves and BIOS settings?
Question about Fan Curves and BIOS settings?
I think it would make more sense to exchange the single cable into one of the three slots on one of them? I’m wondering if it would be challenging to do that right now. Those three would likely connect to: CPU → Cpu_fan, Pump → Pump_fan, and RAM → Sys_fan slots. It seems their curves would differ, except for the pump which stays at 100%. From what I understand, keeping them around 90-95% is acceptable. For lower and middle temperatures, people usually suggest maintaining 40-50°C at about 20-30%, and around 75°C at 50-80%. That should keep them between 50-80% capacity. For the extreme cases, it might be even better to keep them at 30-60% maximum, especially when it’s cooler.
In terms of case fans, I’ve noticed they rarely reach 100% unless controlled differently. Based on what I found online, they’re typically set between 30°C @ 30%, 50°C @ 50%, 70°C @ 85%, and 85°C @ 100%. They probably stay within 30-60% at the highest settings. From your explanation, it seems you could likely lower them further, particularly in cooler conditions.
Regarding the up and down adjustments, some users prefer setting them higher than 1s, with the 1 and 0.7 being the longest times. This is probably to avoid sudden changes that could cause instability or noise. It helps keep things smooth.
The LFIII Pro fans are 3000 RPM so you really don't want them hitting above ~60% during normal operation. I'm not using a LFIII Pro, but I am using the P12 Pro fans on my AIO and around 2000 RPM is when they start getting
really
loud.
As for single connector versus using the separated I think it mostly comes down to personal preference and how much you want to fine tune things. If the behavior of the VRM fan and pump don't bother you sound wise with the single connector then there really isn't much benefit to using the separated connector.
Case fans can be a bit trickier, but generally I suggest running a static speed at whatever volume you're comfortable with. The case you have has good airflow so I don't really think that there's a huge benefit to PWM with case fans. Another option if you do want to go the PWM route would be to figure out what RPM is the loudest you're willing to live with and cap them no higher than that speed.
Step up/down times are completely user preference there isn't really a "you should do it this way" thing.
Exchanging cables might be a bit challenging with the pump installed, but I've managed it before. The top is simply on magnets and can be removed and returned easily, offering improved control over each component. Just adhere to the instructions—they did make some adjustments last year when I highlighted them. For more precise adjustments, you'll need to try it yourself, though most heat will still come from the GPU.
Thank you for the updates.
The stryker mentioned that the VRM fan and pump operation doesn’t really concern me, and I’m unsure if there’s a clear advantage to separating the controls except for fine adjustments. I believe I’ll keep them together on one control now.
CountMike also checked this out; it doesn’t seem too complicated to replace the cables, so I think it’s achievable if needed.
I currently configure them as I’m comfortable with Idle and low tasks, and with higher loads (higher temperatures) I appreciate your guidance in helping me understand better.
