WHOAHHHH 13500. haha That is a faulty sensor bro, no way it runs at 13500 and wouldn't burn out after 2days of usage. That's crazily fast. haha Is it connected to your mobo?
I realise its not going that fast it runs most of the time at about 400 rpm. And its pretty quiet. Yeah it's connected to the mobo. I just wasn't sure if this kind of faulty spike reading is common or not. The mobo is ga-z77-d3h.
