Most mobo fan headers are capable of providing a max current of 1.0 A. You claim your mobo manual says yours can do 2 A. I cannot find that in the manual. I used the link you provided to get the the web page for that mobo, and thus to its manual. p. 14 says nothing about their capacity. The ONLY place I found a 2 A spec is for the plain RGB lighting headers. If the 1 A limit applies, do NOT try to exceed that - you will permanently damage your mobo fan header. Your option, then, would be to plug only ONE of those fans into each of two separate SYS_FAN headers (you have three of these). Alternatively, if that leaves you with not enough headers for all your case fans, you can use a fan HUB that gets more power from the PSU, and can get speed control from a mobo header.
