I have 3 4-pin led fans connected to a fan hub that came with my case, but the fan hub has a male Molex conector and I don't find where to connect it to the motherboard (msi b450 gaming plus) so I can control the speed because it's now connect directly to the PSU, should I buy a female Molex to 4 pin and connected to a fan header? It won't damage the fan header to have the hub with 3 fans connected to it?
