The manual says:
The fan connectors support cooling fans of 350mA~740mA (8.88W
max.) or a total of 1A~2.22A (26.64W max.) at +12V.
and while I don't understand how there can be two current limits,
you are running at less than both of them, so it should be OK.
The first limit is 'per connector', the second is for all the connectors
together. Three fan connecors, 740mA each gives 2.22A total. Why they bother
to give the second figure is that on some other board models, the total is
less than 3* the rating of the individual connectors, so they have 'got into
the habit' of giving both figures.
