I think HR-03 rev.A [not plus] could fit on 8800gt

the 8600GTS stock cooler installed perfectly on an 8800GT. The small dab of thermal compound I applied spread pretty evenly with the pressure applied with the stock 8600GTS heatsink. Therefore, I am reasonably sure that any cooler which is compatible with the 8600-series will also be compatible with the 8800GT.

if you have an 8800gt, you should measure for those dimensions
