if u dont mind it being ugly as hell, slap on a 80mm fan on the heatsink.
throw away those plastic and the built in fan.

i bet the cooling would be much better.

i believe the mounting holes should be standard right?
after all its an abit siluro vga with the otes on it.

i used an abit siluro ti4200 before...im not sure if has 4 mounting holes but the stock cooler was still good. sorry but i cant help you in finding the right heatsink. if possible, stay away from the cm coolviva..they are crap..rm 45 for heatpipe solution, u know why la so cheap.

i think a vantec cooler would suffice in this case. its not that hot and i've seen vantec coolers running on the 9700's which is freaking hot compared to the ti 4200
