Threw another fan into my computer, it is a cooler master that was originally for an intel, while it is powerful, it gets bit more then 4000 rmp :3, it is loud, i set it down so I THINK it will kick to full blast if my CPU reaches more then 45 Celsius. Btw when I first put it in I wanted it blowing towards the cpu and it wasn't, when I put my hand infront of it I accidently stuck my finger into my CPU's heatsink fan, It REALLY HURT xD
