Are you sure you have the model# correct? The Sunon online catalog lists 
a KD1208PTS2 (note the transposed digits) with a speed of 2700rpm, 
36.5cfm, 31dbA, but only 1.6W (not 2.2W). These are sleeve-bearing 
units; if you can get ball-bearing units, they should last longer.

On 01/06/05 06:22 pm Don{ald} O. Woodall tossed the following 
ingredients into the ever-growing pot of cybersoup:

>      I am trying to replace 2 80mm fans in a Cidesign 3540
> 4 bay external 3 1/2" hard drive case.  The Cidesign PDF file says the
> fans are blowing 18CFM.
> 
>      The Cidesign case has 2 proprietary power supplies in it and they
> only provide a 2 pin connector for the fans to plug into.
> 
>      The fans are "SUNON" KD1280PTS2  DC12V  2.2W
> 
>      When I went to   www.sunon.com  I could not get in the
> front door to learn:
> 
>       1. the rotation speed of the fans
>       2. the CFM of the fans
>       3. the decibels of the fans
> 
>      My ambition, desire, goal; is to reduce the noise level
> of the case from what it produced when I got it used, broken, and
> incomplete.
> 
>      Let the ideas come pouring forth.
