I use the NZXT Sentry 2 one right now, and I've had it for almost 2 years now and I've had no issues with it. I use it with 5 fans.
I suggest going with maybe using yours or the NZXT Sentry Mesh Each of these have 30 watts per channel and which means they can support more than 1 fan per channel if you buy Y-cables to split them up
