I ordered the vantec fan from 2cooltek for $16. Well compared to the coolermaster dp5-g11 i had (same as boxed duron and boxed athlon 800) it is way better. Has a quiet sunon 23cfm on it, and is very large (more than twice the size of the coolermaster). Also dropped my temp from 52C at 800mhz to a more reasonable 48C. I'm thinking of sticking my 38cfm delta on there and see how it does. This i a great fan, i'd say better than a chrome orb from what i've read, plus you dont have to worry about killing your chip with an orb.
