I had to disconnect the top fan in my P182 as it made to much noise. I was not really happy with the tri-cool fans noise that came with P182 and had to replaced them with 3 year-old sleeve bearing Cooler Master fans. I replaced 8800 GT with a 9500GT card with a Arctic Cooling Accelero S1 Rev. 2 fan ...

You can get it at svc . com /ncb9225-l.html for $4.99 (remove the space)
I can't find the review, but I'll buy it to replace the fan in my Zalman 9500 to see if it can move more air but quieter.
