Hey guys,

I did my research and no solution yet. It's a brand new build and I'm still very new to this. As I said the cooler is a corsair h110i gt, the mobo is a Asus x99-a us 3.1 and the case is a Phanteks Enthoo evolv atx which came with a pwm hub. The cpu cooler is a 3 pin connecting to the pwm, which also has the case fans plugged into it. The pwm is powered by the sata cable connected to the PSU and the cpu cooler also is powered by anothet sata connection to PSU. The pwm circuit has a 4 pin that is connected to the cpu fan connection on the mobo.
Things I have researched have lead me to believe that the fan speed of the cooler is too slow which pops up the error so I have tried the following, I have tried to change the rpms to 200 and even "ignore" and I still get this error. I have played around with different rpm speeds and other settings and still no solution.
The weird thing is, all fans are running and all the temps are reading as optimal. Sometimes if I turn it off from the back and let it sit for a bit, it's boots to windows like everything is fine, but if I shutdown or restart, the error is back.

I hope I have provided you guys with enough details. I plan on taking it to a local computer store that fixes PC's if I can't figure it out. This build has been really frustrating and I'm really desperate here, hope you guys can help?

Thanks.

With that system the design concept is that the PWM Hub is plugged into the mobo's CPU_FAN 4-pin port, and the hub is connected directly to the PSU via a SATA power output to provide the power to all its fans. There are two functions that use the CPU_FAN connection: supplying the PWM signal from that port to the Hub, and returning a fan speed signal from the Hub to the mobo. Its is IMPORTANT for his last function that you follow the instructions exactly.

There are two connections to make to the Corsair H100i unit: a SATA power connector to a PSU output, and a 3-pin fan connector to "any motherboard 3- or 4-pin header" according to the H100i's manual. Well, "any" is not quite right here. That line from the H100i MUST go to Port #1 of...

How about you plug the system up like is listed in your CPU cooler manual and try again? Most likely the hub isn't passing through the right fan information, and you should never use a hub with the CPU fan pins anyway, most mobos have extra pins for case fans, use those instead (for everything but CPU)

Well, "any" is not quite right here. That line from the H100i MUST go to Port #1 of the PWM Hub, the one that is white. This is the ONLY port on the Hub that can send its fan speed signal to the mobo, so it is vital that the item connected to this Hub port is the CPU cooler system.

You also must have the CPU_FAN Mode set in BIOS Setup to the default setting - that is, in PWM Mode with Automatic control used. This ensures that the Hub will receive a PWM signal and that all the fans connected to the Hub will actually be controlled by CPU temperature. Don't forget that the H100i unit also needs a connection to a USB header on the mobo, and that its radiator fans must be plugged into sockets on the H100i's pump unit. Finally, there is a software app for the H100i that must be installed so that it can do its own automatic control.

Thanks for this detailed reply, I'll make sure to try all the things that are mentioned when I get home from work. Lets hope this is the last of my problems...

UPDATE: Thanks again for the solution. I connected the cooler 3 pin to the white pwm socket and boom everything works. Thanks again!
