Question about what unisink would fit a GTS250

I think the 9800GTX+ unisink will fit on the GTS250 with 512 MB's of video memory. I think the most video memory a 9800GTX+ had was 512 MB's. Will this unisink also fit on a GTS250 GPU card with 1 GB of video memory (1024 MB's)

The reason I'm asking is I've read where the PCB on the 1024 MB video memory GTS250 card was a 1 1/2" ich shorter than the PCB on the GTS250 card with 512 MB's video memory

Thanks for any answer
