Interesting! I'm just looking at the fans in my Indigo 2 right now and the Octane hdd and cpu fans are identical to the psu/gio and cpu fans in the I2!
I found this fan http://www.overclockers.co.uk/showproduct.php?prodid=FG-011-SY&groupid=701&catid=57&subcat=820 , which matches the 56CFM maximum of the Panaflo but is a couple of dBa quieter.
Have you found anything specific for the cpu fan yet? I've found it hard to get specs for reasonable 60x60x10mm fans - though there are lots of 60x60x25mm models out there. Also, you can use a 3 pin fan but just don't connect the yellow wire - it's just used to read the fan speed that's all.
