PWM fan hub: reasons to use over mainboard fan connects?

Featured Replies

MSI Pro AMD5 board that has enough fan headers to cover case fans etc.  The Phanteks case I am using came with a built-in PWM fan hub which I've never used and near as I can tell the only reason to use it is to keep wires from my 6 case fans on the back of the motherboard where the hub is affixed rather than in the main case area.  Any other reasons to use this over direct connects to fan connectors? 

Cheers

If using RGB fans, can be useful for controlling RGB on all fans (matching or synchronous colours) assuming the rear fan hub is an RGB one. It does help keep the front side neater. Downside is that all the fans connected to it are usually controlled as one. That means you cannot set individual fan speed curves for those fans. If plugged into separate headers on the m/board you have more control. That’s because the UEFI BIOS sees the rear fan hub as a single fan, Also nothing wrong with using the rear hub for some fans and the front board connectors for others. Always a good idea to connect CPU and water pump fans to their dedicated front side connectors regardless.
