Sometimes higher rpm fans need slightly higher voltage to start moving as they typically have a slightly higher starting rpm. Did you try adjusting fan speed manually to 100% to make sure it’s not a dud? If you can control fans in bios that would be a good place to troubleshoot.

Very nice. Glad that worked out

Unless you're talking about a super small VRM/MOS fan that your motherboard should have, I don't know what cpu fan you're talking about. These are the only fans I know of in the system: Top Fan VRM/MOS(tiny and exhausts out rear IO) Power supply GPU has 1 on each side of where the radiator attaches I plugged my top fan directly into the motherboard CPU Fan header so maybe doing this would help in your configuration. I have a different motherboard and GPU so maybe my config file won't be ideal for you but if you still want it I'll send it.

Exactly how I have mine setup. Fan Control embarrasses everyone else's attempt at a fan software.

That could definitely work. Post back here if it does as I’ll probably be doing the same if I manage to get a 3080.

If you mean i164 then that has a z370 motherboard which does not support PCIE gen 4 (which is what that drive is). The drive will work but it will function at PCIE gen 3 speeds. This is still plenty fast it just won't support the highest speeds the drive is capable of. If you want to take full advantage of that NVME drive you would need to swap in a newer ITX motherboard (which would then require a new CPU and probably RAM). The DP extension cable is part of a little proprietary box that attaches to the inside of the case and connects to the gpu's outputs. This is not upgradable unless the newer systems use boxes with same length cables and same screw mounting points and you can find someone selling that specific part. Another option is to remove that little proprietary box all together and run your cables through the gap it leaves inside the case and plug directly into the gpu. This would mean you can't plug and unplug the DP cable unless you take the system apart and you'd need to find a cable that is flexible enough to plug in since it is very limited space.

That’s the only fan I have it controlling as it’s the only case fan in these systems. The top fan technically cools the cpu and gpu by pulling air in through the passive radiators on each side. Look for a tear down or review of these systems if you haven’t seen how they are built. The GPU fans still function autonomously using their default behavior in my system and that has been perfectly fine. I set mine up the way he did in the video only exception being I added SSD temp for my NVME since it gets pretty warm. So I have 3 inputs(cpu, gpu, and ssd) and whichever requires the highest fan speed takes priority.

I did this with a z590i Unify motherboard that has Thunderbolt 4, took some BIOS changes but they work now. It sucks the first time you tear the system apart but it's doable. After that it goes much more quickly. You have to remove pretty much everything from the system and I recommend removing the front and rear panels as well(be careful not to break the clips). The case is weird but it's still just a computer case so most parts will fit(ITX motherboard, SFX power supply, 140mm fan). Stick with LPX or other low height ram for radiator tube clearance. If replacing the GPU then card dimensions will be important. I think max length is ~268mm and if you remove the radiator(since it's almost impossible to adapt to a different card) it might fit a 3 slot card but easily 2 slot. If you upgrade to a motherboard/gpu with PCIE gen 4 the gpu riser cable will need to be replaced as well otherwise you'll have gen 3 speeds.

I also upgraded my fan in my i165 to the ML Pro and it's the same noise until it reaches a higher rpm than the old fan is capable of, at which point it is obviously a little louder and cooler. I think the ML Pro might be what comes with the newer Corsair One systems though so you may already have it. Personally I am very happy with it and am not looking for a replacement. If you run a stress test and it gets to 2000 rpm's then it's safe to say that's what you have. There's also a chance that it is software limited to not reach max rpm to keep noise down.

The software Fan Control on Github does exactly what you describe. My system is silent and ramps up for cpu/gpu whichever is higher as needed based on the curve I set. I know you don't need it but I'm trying to spread the word since it's perfect for our systems. Getting away from icue was the best upgrade I've made. Hoping it helps someone.

I did some stress testing with the default fan curve just to see how it would perform. CPU test thermal throttled due to fan taking so long to spin up and never reaching a fast enough RPM. GPU test ran ok with the exception of the system blinking red lights every so often while spiking fan RPM to max for emergency cooling then dropping it back down once its "ideal" temp was achieved. It did this over and over again and while it did not thermal throttle it was very annoying. For anyone wondering here is how I setup Fan Control with the caveat that I do not have iCUE installed and will not reinstall it to test it. I unplugged the top fan from the pump connection and plugged it directly into the CPU fan spot on the motherboard. I installed this software and made a custom curve for the CPU, GPU and NVME drive separately based on the temperatures and sound level I desire at specific loads. I used CPU Package Temp, GPU Temp, and SSD Temp as my temperature signals. Then I made a Mix-Max curve based on all 3 I previously made(this makes more sense when you're looking at it). This now uses the Max Fan rpm called for at any time by any of the 3 components I set up. Another change I made is having the fan decrease in speed more slowly when the temps drop to help eliminate some heat soak after an intense workload. This also helps prevent the fan from jumping around in RPM's as much. It is perfect for me and infinitely adjustable on the fly. I have no use for the coolant temperatures or pump rpm's but they are still visible in HWiNFO64 if someone wants to stare at them. The little fan on the 2080ti heatsink still functions just fine on it's own adjusting as needed.

I honestly couldn't tell you how it will interact with iCue as I abandoned that software as quickly as I could. I think if you are able to see the sensors in HWinfo64 or a similar program you would be able to use them to trigger the fan curves. Someone would need to download this software and check to see if the temperature readings from the gpu/cpu show up and are configurable as sensors(I'd bet they will). I personally have been using pumps and radiators from both versions of the C1 mixed and matched with no issues in my builds. I have the pumps running directly from the motherboard and they are at a static speed with no noise or performance penalty in my case. Top fan plugged into the cpu fan header and then use this software to have the fan ramp up with signals from both gpu and cpu whichever is higher takes priority.

I’m not sure if it’s been posted on this forum yet since I’ve been away a little while but the software called Fan Control that jayztwocents did a video on 3 weeks ago is perfect for our systems. You can have the fan ramp up based off of multiple inputs and fine tune everything. Works really well for me since I’ve replaced every single part except the passive radiators and didn’t want to deal with the old software and it’s “nuances”. I quoted you because you helped me in the past and seem to be on top of everything Corsair One related. I’d add a link to his video or the GitHub download but I think I remember something about not posting links for some reason.

Does anyone know it? Don't have originals and need to order some.

I'm saving that as a last resort but happy it's an option. I'd really like to preserve the efforts they put into designing the cooling in these cases. I know they've made the cooling brackets for 10, 20 and 30 series but you can't source them outside of buying a full system. I haven't decided on a gpu yet because I was hoping to find one of those brackets and just get as best I can to match it.

Very much appreciated information echosierra. I think they may be the same length as well even though the newer models have the motherboard and gpu orientation flipped. Going to order a 200mm and give it a try. Now if I could figure out what everyone's been doing with their HG10 style cooling brackets, can't find them anywhere.

I've got an i145 case that I'm building in and need to order a PCIE riser but I don't know how long I need. Has anyone already done this and know a length that works? Or can someone measure theirs so I can get an idea of what length before folding will be required. I'd like to avoid buying the longest I can find and having a bunch of excess blocking airflow.
