Too high price, i need it just for few photos.
my Bvision needs no cooling on the ram even at 100Mhz,above 100Mhz their start to get warm,but this is a on going project & will post when heatsink is needed when temperture is too high.
Yes, CVision ram cooling is not required.
In addition, the radiator is not a solid under the fan:

Most of the air flow goes to the left, through the cooling fins under the video chip, and smaller - down through the holes. that's enough, that would cool the memory, if I overclock it.

So there is no need to grind the base of radiator or underlay plate that would make contact with the memory.
