btw, while i posted i had options to post sticky and announcement, for a sec i though i had been given mod status , i think you need to check the permissions in board control for the hardware board as normal users have some extra options they shouldn't
Well, fan adapters give you one or the other. If you are running a low performance fan, the noise won't increase, but it will push out more air; if you are running a high performance fan, the noise will decrease, but it will put out as much air. This is because you are running a given amount of air through the smaller hole size, except it is eased into the increased pressure (vs. larger hole). I would just suggest getting out the Dremel and increasing the hole. Heck, just put a window in while your at it.
vee...I seem to be getting mixed signals...or I am just plain slow. At first it apprears that you are talking about a fan adapter on the heatsink for your processor...and later you seem to be talking about a blow hole. I am concerned with the heatsink on the processor...fan adapter...putting a bigger fan on with lower decibel, but higher or equal CFM
