I'm speculating that the technical specs for this year may have exceeded Zepper's off-the-hat common-sense based on last year, just as they did mine.
I don't know about the ABIT motherboard. Unless I should do it for you, go to the motherboard manual, find the section on the fan plugs, and see if they give an "average per plug" amperage spec and a "cumulative" amperage spec.
My mobo is a Striker Extreme, and it has eight fan plugs. The manual says that each plug is capable of handling >= 0.32A @ 12V and less than 0.80A @ 12V. It also says " . . . or 7A @ 12V total." By this, I've verified that they mean that you could put a 0.90A fan on each of four plugs, and still have only used just short of four-sevenths of the motherboard's fan capacity.
What I meant about Zepper's remarks is this: My last build was used an ASUS P4P800SE motherboard, and its cumulative fan-amperage spec was around 2.5A. Until two months ago, I had assumed that this was what I could expect for the Striker, but consulting the manual made it clear that newer boards are a whole new ball-game.
As he said, you can splice fans together if you splice them in parallel. I urgently recommend that the fans spliced together be of the same make and amperage-draw. It is convenient to do them in pairs. So if you had two Panaflo's rated to draw 0.6A of current, you would get a total of 1.2A pulling off one plug, and unless your mobo manual says otherwise about an individual plug's limit, the effective limitation would be the cumulative fan amperage for all plugs combined.
But here's the rub. If you splice them together and you want tach-monitoring of fan-speed, you would leave one fan's tach-wire disconnected and only connect the tach-wire for a single fan, or you would run the combined fans off one plug with one tach-wire attached there, and use up another fan-plug for the monitoring wire from the second fan.
If I'm mistaken about this, someone should correct me, but I'm pretty sure of it (having done these things.) In your case (ha-pun), and if it were me, I'd use the limited number of fan plugs for your more powerful fans which you want to spin up with temperature, and then hook the slowest, quietest fans to the power-supply directly. that assumes that you have thermal sensor wires that pair with the fan plugs, or that most or all of the fan-plugs can be thermally controlled off the motherboard. Otherwise, you might be wise to look for a fan-controller.
But in all cases (including the CM 830 and "pun again,") -- follow the KISS principle.
