Is it normal for the fuse to be warm to the touch on high clock? I have 2 cubes, one doesn't like high clock, the other one seems ok but the fuse is warm to the touch. I have only had it on high clock for 4 or 5 hours now after running on low for a couple days, but I don't know if I should leave it on high or not.
It pulls more power through the fuse on high, so, yes, I'd expect it to be a bit warm to the touch.
Not overly hot, but if it's slightly warm, it's not a problem.
