What the best off-shelf fan controller that can handle 2 or more fans per channel?

I have scythe UK 3000, one on each channel, its been runing like this for months and no problem at all

How much are the UKs undervolted? I think that's the deciding factor, minus the lemons that some of the early adopters got

Yep, the less you undervolt, the less heat dissipation the components need to do.

thanks for confirming that. I'm seriously considering slapping some small ram heatsinks to the Kaze master...I think the 4 black rectangular thingies next to the fan headers get pretty hot, but I was just wondering if anyone had any luck cooling other parts since the entire panel got pretty hot in my case
