ok well i tested it just now and its how i thought
, the psu is the thing generating the noise. I dont udnerstand how it can be this loud when a 120mm fan on full is quieter than this 14cm fan, its ment to be temperature controlled but it is pretty loud i think its not working correctly. Im going to take it out of the case and double check though.
edit, after taking out of case and clearing out the dust it still is loud, the fan is a constant 100% as far as i can tell, its ment to have a silent tempersture control which in my opinion isnt working. Think its worth emailing xclio?
