How to control corsair h115i fans from bios?

Hi i have a corsair h115i liquid cooler, and the corsair link runs perfectly with the app opened in windows. My issue is that i need to use linux, and i would like the fans to stay quiet, so my idea was to instead of using corsair link just connect fans directly to MOBO and regulate the fans from the BIOS. Any idea on how to do that? Thank you for your attention.

You plug them into the motherboard and then set the fan curves in the UEFI.

I know asus motherboards can do it, idk about other boards.

The problem with doing this is that you can only control them by CPU temp not water temp. Liquid cooling should not be controlled by CPU temp since the fans are actually cooling the water, not the CPU. For example, if you put a load on your CPU then the CPU temp will go up instantly, which will increase the fan speeds unnecessarily since the water has not warmed up yet and increasing the fan speed won't cool the CPU any better. The same is true when you stop a load after extended use, the CPU temp will drop quickly which will make the fans slow down but the water in the loop will still be very warm and need the fans to keep cooling until the water temp drops back to idle temps.

 

You're much better off controlling the rad fans using the water temp (using the AIO fan controller) and setting a custom curve in LINK since then it will actually be controlled by the temperature that matters.

 

Obviously that's not possible with linux but you might be able to use a custom fan controller program which can read the water temp from the AIO via the USB connection and control the fans based on that rather than the CPU temp.

Having issues with a Corsair AIO? Possible fix here:

Are you getting weird fan behavior, speed fluctuations, and/or other issues with Link?

Are you running AIDA64, HWinfo, CAM, or HWmonitor? (ASUS suite & other monitoring software often have the same issue.)

Corsair Link has problems with some monitoring software so you may have to change some settings to get them to work smoothly.

-For AIDA64: First make sure you have the newest update installed, then, go to Preferences>Stability and make sure the "Corsair Link sensor support" box is checked and make sure the "Asetek LC sensor support" box is UNchecked.

-For HWinfo: manually disable all monitoring of the AIO sensors/components.

-For others: Disable any monitoring of Corsair AIO sensors.

That should fix the fan issue for some Corsair AIOs (H80i GT/v2, H110i GTX/H115i, H100i GTX and others made by Asetek). The problem is bad coding in Link that fights for AIO control with other programs. You can test if this worked by setting the fan speed in Link to 100%, if it doesn't fluctuate you are set and can change the curve to whatever. If that doesn't work or you're still having other issues then you probably still have a monitoring software interfering with the AIO/Link communications, find what it is and disable it.

Thank you, Do you have any idea on which extra cables i need? or can you point me to someone that has done it? I think i need a cable that takes the 3-pin of the two fans and connects to the cpu fan in the MOBO.

So you need a fan splitter?

Does your motherboard not have more fan headers?
