I have found that there is only about 12-16mm of gap between the top of the fan and the top of my case, so its no wonder its going to full speed warp-9 takeoff velocity when doing anything cpu intensive. It sounds like its doing that tubine nose thing like when you restrict the airflow with your hand or something.

So I need one that either passes the air thru it horizontally, or one thats a lot shorter. Preferably a cross ways fan one since that will go straight into the exhaust fan...

But _QUIET_ = the case is an old low profile one I got a while back to put my firewall into before that idea fell down. I really need a lid on it before it goes in the loungeroom.

If you are handy with power tools and really want to keep existing cooling system, you may try to install something like this: (you will have to cut the lid)

I would go for a size bigger than the fan diameter (if the fan is 80, go for 120 grille). Once installed, the filter version will be higher than the surrounding surface with approx 5-6mm, I installed one of these on the side of a case of an older computer (back then the cases did not use to come with "air pipe" - or maybe I did not pay attention to that detail until I started to edit and process the videos from my camcorder into dvds and the cpu used to go as high as 60 deg C).

I am sure you can find a way to install it flash with the outside surface, but it might involve more fiddling with the grille/filter installation. And would make the filter removal more difficult, I think...

Alternatively you can drill lots of holes (in a pattern of your choice) right above the CPU fan.
But then the noise is free to go out, and the dust to go in...

I can see you posted your message at 2:04, I hope the noise from the fan was so bad to keep you awake...Wink
