Alright theres a story behind this so bare with me  I left my house for a week and come home to see that my sisters fish tank exploded in her room later seeping a small puddle onto the top of my Dells casing from upstairs  the puddle was located on top of the case to the left of the case where there are no openings for water to flow onto my motherboard  the only thing that did have some water in was my Power supply  which was very dusty time  with the little bit of water and the dust made a pretty big mess  i left it for a few hours on is side where no water drained out  i was amazed  but when i turn it on  my cpu fan does 9999 rpm's and my power supply fan does none
