Question Can sata powered fan speeds be controlled?

[Proprietary Software]

My case has 4 preinstalled fans wired to a hub that is powered by sata. Can the speed of these fans be controlled? I have a msi motherboard, and in the bios, I have the option to set a speed curve for them. But I am not sure whether the curves will work.

If the hub's only input is a SATA power cable (no 3-pin or 4-pin fan cable) none of the connected fans can be controlled via the BIOS or any software.

Are there adapters I can buy though to convert sata to a 3 pin?

bios controls the fans that are using the mother board fan headers . where you buy a pc with fans connected to a sata hub sounds so strange to me hehe. i would replace the fans with some better ones and use the mother boards fan headers that way could have more control over them.

could you take a picture of the hub that the fans are connected too ?

thinking the hub mite be connected to the mother board maybe so it mite have some way to control them using the bios 🤔

pwm on a fan just means it has a extra wire (signal) making it 4 instead of 3. pwm stands for pulse width modulation lets a mother board control the speed of the fan . were as the 3 pin fan has no signal wire so it basically goes at 5 v or 12 v making its speed non controllable unless the mother board supports voltage controlling. sata direct current unless the hub is connected by some thing to the mother board or usb or some thing i would think it just runs them at a set speed

it depends on the hub

Tell us what case maker and exact model number. Then also tell us maker and model of you mobo. Then we can look up details (rather than guessing) and advise.
