I have seen variable speed dehumidifiers as well, I just assumed that slowing that big fan down too much to make it quiet, would hurt performance too much. I'm dead set against noise now. Some noise is quickly drowned out while gaming, but I find myself drifting away from gaming, and this system is more a jukebox/DVD player than anything these days. I guess I OC out of habit/addiction now ...but how many DVD players are on the market that do distributed computing? Those extra cycles are justified.
So I'm gonna be doing a pump replacement/ line reroute soon anyway, I might as well kill 2 birds while it's apart, and add my chiller. It's gonna be an expensive year...
