i was rearanging my wires in my case and i accidently hit my tt volcano 11 fan on my cpu and it made this terrible noise so i instantly shut it off and i looked and i brok a blade off the fan how stupid of me i hat that fan anyway
but why are you poking around your computer while it is on? well i do it too so i guess im calling the kettle black. My favorite fan is the vantec tornado. It is a bit loud but you get used to it.
or you could dump the volcano 11 cause they are loud for what they do and get a areo cool deep impact now they are quiet even when you have both the ally fans hookedup and at full power!........plus it looks very nice too!
That is a crap heatsink Id get a Zalman 7000 Al/Cu instead; return that Aero 7. They are not worth the money, especially not the lite. If there were a puke smiley I would use it now.
