    Strix Z270E MB PWM case fan issues

    Hello Community how are you?

    I wanted to check with the community to see if anyone is having the same problem as I am. I have a 7700k paired with the z270e motherboard, along with the corsair h115i. I currently have 3 case fans hooked up the the PWM fan headers. I have two 140mm fans and one 120mm exhaust fan. The issue that I'm having is that my fans are throttling from the highest rpm, to the lowest rpms. It almost seems as if whenever the CPU comes under the slightest load the fans will ramp up and then gradually go down. This will repeat itself the whole time my machine is powered on. So far I have cleared my CMOS two times. I have reinstalled windows 10 twice along with that. In addition to these things I have tweeked the Q fam control quite a bit. I have tried manually configuring when the fans whould go to higher Rpms etc... I have even tried to put the profile on silent mode to no avail. Before I have the 3pin pump connector in the AIO header, and I had the other 3 fans in the CPU header, cha1, and cha2. As part of my trouble shooting I have put the pump header in the CPU output and placed the other fam headers else where. I have exhausted all options have have sinc e contacted Asus to initiate a Rma. Is it something that I'm overlooking? The last thing I want to do is RMA my board so any helpful feedback I would be most gracious.

    Also, make sure you connect the USB from Corsair H115 to the USB fan header (ROG_EXT, , looks like USB header with 1 pin missing)
    In BIOS, I went to monitor -> Q-fan Configuration -> AIO_PUMP/W_PUMP+ Control -> Disabled, F10 and saved. I let the Corsair LINK have full control of the water cooling fans and speeds.
    I also did a QFAN Tuning in monitor and then Disable AIO_PUMP controls

    yes everything with the AIO system is hooked up correctly. I already *have two fans that are currently hooked directly to the AIO cooling system fan connectors. I do have an PWM fan splitter I'm going to try what you suggested and hook all of my case fans up the the AIO cooling system so that the corsairlink software can control everything as you mentioned.*

    I'm set up the same way and use Fan Expert to control the pwm case fans. You can adjust how many seconds of tamp up/ramp down time in the fan profiles. This controls the surge nicely on temporary CPU temp spikes.

    Thank's for the information I will certainly implement this!
