Thank you in advance. The goal is to engineer the fan in such a way that at a wide range of speeds (fans increase and decrease PWM as needed), the fan's performance curve exhibits a bump right where it intersects with the The reason why I set cooling seperately is because if I base the fan speeds on cpu temps only. It is stuck at 100% PWM at 70C. There is a free fan controller software that Jays2cents mentioned. Most usage you won't hear this increase. I do intent to undervolt the CPU at some point to reduce power consumption and run cooler. This will stop it hitting 100% That's mainly to do with your ambient & idle+load temps & where you set the points in the fan curves, the 'step down' time I mentioned will stop the fans instantly changing speeds due to fast fluctuations but you'd want to set the temp/fan speed ratios at a sweetspot to avoid them changing too frequently if that bothers you, you just want more 'points' in the curve to narrow the gaps between Best cpu fan curve for Noctua NF F12 chromax? I bought the Cryorig H7 on a Newegg deal and replaced the stock fan with a Noctua NF F12. May 7, 2024 · PWM: These fans are also four-pinned but are small in size and are connected directly to the motherboard, meaning their fan curve can be adjusted. Load Curve – Lets you create a custom fan curve that is related to a load sensor that iCUE has access to. I got my Ally a few months ago and just when I was getting into setting manual fan curves was when ASUS released the update that adjusted every stock setting. If there was the case that the fans were at full blast all day everyday, then that might've been a cause for concern. Jul 31, 2023 · What Is CPU Fan Curve? Before we dive into the process of changing the CPU fan curve, let’s first understand what it means. Try to set ramp up at level 1 and ramp down at max level. So you ideally need a curve that works in multi and single load scenarios. All the fans ramping up on the CPU except for the top 2 which ramp up on the PCIe 16x slot. use this at your own risk. In theory this might give an optimum quiet fan when the PC is doing light work and fast fan speed when it is pushed hard. If you modify it in BIOS, the fan Works as set, but after rebooting, the fan curve will just reset to stock. I meant a temperature which would cause problems with the hysteresis and my fan curve (turning the fan on again shortly after turning it off). Quiet Mode: The fan runs in a quieter level than Balanced Mode. I'm trying to understand how fan curves work, and if there any single optimal ones to use. I'm pretty happy with the results (even got 3'C less than before on the Throttlestop stress test). manually adjusting fan curves can be dangerous (might break your device). Dec 26, 2022 · For the right part of the fan curve, benchmarks are most useful, i. Instead of blasting air at full power all the time, a fan curve lets you decide when and how fast your fans should spin based on the CPU’s temperature.

H115i pro model, the board did not get either fans plugging in to cpu-fan 1 and pump fan 1 connector pwm mode and the three pin disconnected. Fan speed is a trade off between airflow and noise. Using the Balanced setting in AWCC my idle temps are about 40C, and under load I see highs of 70+ including some spikes to the low/mid 80s. You will see a selection of available sensors in a drop-down list just below the curve. Would the case fans then help to lower the temperature of the GPU or would it just cause the fans on the actual GPU to do less work. However, I personally find variable fan speed to be even more annoying than normal fan speed. Normally OPT_FANS are linked to thermal sensors mounted near them on the mobo. Jun 12, 2019 · Normally, MSI BIOS allows to modify CPU (and other fans) Fan Curve, but it's IMPOSSIBLE to save it. I’ve been running pretty much everything on the 15W preset but would like to explore beefier fan curves now! The ‘P’ and ‘Q’ simply come from the variable commonly used for pressure and airflow in engineering. Or, since those curves are hard to come by, simply run a stress test on your cpu and set the fans to max speed, then lower the speed and see how the temp changes. It was more like a step ladder curve, where gaming was within a certain range, minimal load was in a different range. Fans are rated for thousands of operating hours, higher or slower rpm don't significant shorten their life span. Yeah, they're 4-pin fans. A popular CPU benchmark is the Cinebench, for the GPU the Furmark is something quite simple. the problem is the mobo sees the cpu hitting 70c and bumps fan to handle 70c but by the time the fan gets there the cpu's dropping and now being overcooled. Try setting all the fans at 45% speed up to about 52 degrees Celsius. I've read nothing but horrible things about Armoury Crate and the Manual Mode for fan settings. I then call the mix function “140mm Front”. That decreased my CPU Package from 97c (max) to 86c (max). You might need something different. Apr 22, 2019 · For fun, I just changed my rad fans to follow CPU instead of Liquid, and that made my fans go to a 100%. You can still adjust the power profiles and some of my fan curves on newer bios but just not anything past 60c since the fan% is locked by Asus then. Obviously, this curve takes a lot of playing around with to suit your needs. It seems 100% CPU fan and 70% case fans may be the sweetspot for me, the stock CPU fan is loud no matter what but the thick glass muffles most of it, and at 70% case fans, it doesn't get any louder and the fans have a pleasant sleepy sound. Oct 12, 2016 · A three-pin plug means the fan is DC (= direct current) voltage-controlled. For a voltage fan that just means less voltage is output.

If they're still a ways from 80C, then lower the percentage even further. But I gotta admit that I don't know much about tweaking fan curves, so I'm here to ask if you guys think that this is ok. Maybe someone have an idea how to do it or how they done it. The highest fan speed at 4K native max settings (99-100% GPU usage all the time) is 35% (custom fan curve set to 35% at 70c), the edge temps never goes above 70 degree Celsius and the hotspot temp remains under 85c. Jun 5, 2024 · Verify fan curve settings: If your GPU allows fan curve adjustments, ensure it’s set to activate the fans at a reasonable temperature threshold. While CPU Tctl/Tdie can be disproportionally above average. My idle temps are 39°C and the 69°C was a hypothetical temperature to show how I understand the way the hysteresis works. A graph of Fan Speed vs Temperature will show up and unlike the Fan Speed meter, you can reduce the fan speed to as low as 1%. I've tinkered with the fan curves in BIOS simply to make them a bit quieter, and to set a couple of fans to the GPU temp sensor. frankly i have no idea what i'm doing since there's no documentation from asus on how to manually adjust the fan curves. Both the cpu_fan, sys_fans 1 & 2 curves are the same. We will be moving those to adjust our curve. 25% already where the temperature scale starts, usually 10 or 20°C.
