80mm Fans < 25mm thick

[emogoch]

Are there any any 80mm fans out there that are less than 25 mm thick? I have an Antec P180 case, which has that duct that sits right about the Gfx card. However, cause my card is somewhat tall (7800GTX), I can't fit a standard 80mm fan on the outside of the ducting, and having it o nthe inside severely limits airflow (as there's only lik 2 mm clearance between the fan and the top of the duct. Thanks

The Evercool Thin 80 x 15mm fan might work for you. (Model EC8015M12CA).

I found one at http://www.performance-pcs.com/ for around eight bucks.

Keep in mind that the air flow will be quite low for this less than 30 CFM as the pitch of the fan blades are reduced due to the 10MM depth reduction.
