I’m not sure what info I need to provide so I’ll try my best:
I have 2 fan headers on my mobo. One is for the liquid cooler fan on the radiator. The other, I just recently bought a fan hub, and connected it into sysfan2.
Problem: I have 4 fans connected into the fan hub. When I go into bios, And try to set fan curves, I guess the hub overrides it because they constantly spin at the same rate no matter the bios settings. Is this something software fixes?
This depends on the fan hub. Is the fan hub connected to a 4 pin fan controller? My fan hub came with the case, meshify s2. It connects to the pwm 4 pin cpu fan and it connects to additional power off of the ssd power connectors. My cpu fan connects to the fan connector 4 pin. My case fans connect to the 3 pin. Cpu fan connector on mb sends tells the fan hub how fast to spin and the hub sends that data to all fans.
A 3 pin fan connector controls the fan speed by the amount of power it sends. Obviously, 1 fan connector cannot give enough power for all the fans on the fan hub so the hub should be connected to additional power. This means, a 3 pin connector cannot control fan speed on a hub but a 4 pin should be able to if the hub has a 4 pin connector
Sorry should have linked it. DEEPCOOL FH-10 Integrated Fan Hub, Powering up to 10 Fans (3-pin Non-PWM or 4-pin PWM), Occupying only One 4-pin Motherboard Header https://www.amazon.com/dp/B077YHLDSP/ref=cm_sw_r_cp_api_fabc_D8sYFbYNW5C9V?_encoding=UTF8&psc=1
Should mention the cpu fan header is taken by the AIO as well in its correct position.
From the description, your connecting the fan hub to a non pwm 4 pin. Is your sysfan2 a 4 pin pwm header? The only part I’m not sure, the 4 pin connector for the hub does not look like a 4 pin connector or a 4 pin connector without all the pins connected.
Have you tried to connect to liquid cooler fan and connect the radiator fan to the hub?
I am not aware of any software that can fix that. The hub spins all the fans at the same speed based on the inputs of the SYSFAN2 header.
Does your motherboard have a CPU fan header? You should probably connect your AIO fan to the cpu fan header. That would potentially free up the space for SYSFAN header
