Note that the Fr33Flow is just a block - the pump is added separately so you can choose whatever pump you want. Many pumps come with a 4-pin molex for power anyway and just use a 3-pin fan-style header for monitoring. So, it depends on which pump you choose and that pump may be too powerful for an AIO header anyway. AIO headers, like fan headers, are often capped at 12 watts and DDC pumps can draw as much as 18 watts.But, there are pumps out there that are either powered by a fan-header style connector or they are low enough in power draw that they can be rewired to do so. In that case, as [USER=10551]@PBJ[/USER] mentioned, a dedicated AIO header isn't really all that special beyond the default speed profile assigned by the BIOS.
