Is there any kind of PWM fan controller that I could purchase to manually control the fan speed of a Baikal X10? I would imagine they make something like this for different types of fans/motors. I've looked on eBay, but they are a lot of circuit boards, and I'm not sure what to get. I purchased a Noctua NA-FC1 from Amazon, but the connectors don't match; it's more for computer fans. Thanks.
