My X2 started to make a strange noise from the controller box when powered up. The noise was like a bearing going bad, sometimes very loud, sometimes lower and usually after several minutes it would disappear. I didn't think there were any moving parts in there until I removed the cover plate and discovered the cooling fan was the culprit. A quick shot of lube between the housing and fan blade and all is well again.
I haven't checked the voltages, but I suspect a computer fan would be an easy replacement in the future. Another thought occurs that I could put a second fan on the opposite side blowing in to aid cooling.
