Hi everyone.
I've just got my Define 7 XL case yestoday and installed all my components. The case came with 3 stock fans that are installed. I purched 3 noctua NS-12A FLX fans on the side and installed them in the front, and moved the 2 that was there to the back top. So i got 6 fans in total in my case.
I'm using the Define fan hub that is pre-installed into the case where there is room for 6 fans. The fan hub is conected by PWM cable to the CPU_FAN header, and the CPU fan is connected to a specific CPU fan slot in the fan hub. It's installed as Define recommends.
Now to my problem.
The 3 stock fans are running fine during boot and the rest of the time including with load. My noctua fans on the other hand is spinning fine when I boot my PC, but begins to stop a short time after i reached the desktop. I've tried to put some load on the CPU and reached around 40-50 degrees but the fans still won't spin. I have checked the BIOS settings for the CPU (which i assume is the control for the fan hub now that PWM cable is plugged into that header) and it looks fine. I can even get the noctua fans to spin in different speeds (alongside the stock fans) when changing the settings while I'm in the BIOS. I can hear and see that they ramp up.
(The noctua fans is connected with extension cable + RC10 low noise adapter, if that has anything to do with it?)
Also ALL fans are 3 pin, not 4 pin PWM.
I've been thinking that this might be a power problem?
I've got an OLD 500W supply for this system:
1x Intel Core i5-9400F
1x Arctic Freezer 7 Pro
1x ASUS ROG Strix B360-F GAMING, S-1151
1x Corsair Vengeance LPX DDR4 16GB 2666MHz (2x8GB)
1x MSI 1060 6GB Gaming X
3x stock 140mm fans
3x Noctua NS-12A FLX
1x Kingston SSD
1x HDD (old, brand unknown)
I hope some of you got any suggestions.
Best regards.
