Yes, you'll likely only have CHA_FAN1 and CHA_FAN2 available on that Motherboard.

You can use a y-splitter like these to connect two fans to a single header. Just don't connect more than two fans to one header as they have a limit of 1A total power delivery and each fan will use up to 0.3 amps or more. Ideally you want both fans connected to a single splitter to be of the exact same type and model.

You may need to double check if your existing fans use 3 pin or 4 pin connectors too.

Here are some 3-pin splitters also - in a pointless but fancy box!

Thanks for the reply the fans that are connected too CHA_FAN1 and CHA_FAN2 are the ones that come with the case. How would I find out if they are 3pin or 4pin? Also could I connect a fan to the M.2 Header ?

I can't tell what type they are - I'm not familiar with the Airguide fans and the ones that the case comes with I think are different from those you would buy separately.

Simplest thing to do is take the plug of one of them out and check I would have thought?

I don't see any reason why you couldn't use the M.2 header actually. It's rated the same as the other headers and control is independent and is configurable from Q-Fan within BIOS or via whatever other application you might use for Fan Control.
