Is there an aftermarket cooler for 2900XT

I have a HIS 2900XT and as it has the stock cooler/hs on it, it is the noisiest component in my system.
I have seen aftermarket coolers starting to emerge for the newer 3 series cards and 2600 but not the 2900.

Anyone know if one is either currently or shortly to become available?

Those used on the 3 series are generally compatible with the 2900 as they apparently have the same mounting holes (same as the 1900XTs). Something like that mammoth AC S1 or the ThermalRight HR-03 (both will need a fan) should work fine.
