Dissecting The X1900XTX Stock Cooler....
Since I took off the stock cooler to replace it with the vf900 I decided to take apart the stock cooler and see what makes it tick inside...
The cooler... still in one piece..

The back of the cooler.. You'll see five little screws, these hold the base and top together..
Now it's easier to get laid on the Internet then to unscrew those screws.. I actually had to use near brute force to get them out...

The base of the block which makes contact with the GPU.... You can see it's machine polished but it could be much worse... *cough*Big Typhoon*cough*

The noise maker.... (??)

I wanted to know if the cooler itself is that loud or if there are other factors which makes the Boeing 747 take off noise... so I hooked it up on a 9v battery..

Yes there was some noise.. but definitely not the noise you normally hear. far from it actually...
If I had to label it it would be quiet/slightly audible <30db...

Next was to place the fan back in the white casing and let her rip again...

Noise levels did increase a fraction but still nowhere near the 747 noise...
I had only one option left which was to cover the bottom of the fan top.. I used a plastic transparent plate to cover the top and instantly I was welcomed with the familiar 747 noise..
Sorry for the bad pic but I only had smoked acrylic....

The noise definitely is generated by the very narrow opening between the base plate and the plastic white cover.. It has to suck the air through the tiny opening which cause the noise...
One makes you wonder what effect it would have if you create a bigger opening.. you will lose a lot of the effect the fan creates probably.. but I'm not sure about that one yet...
