Ive just installed an Arctic Acelerro Extreme 2 on a powercolor 6950. I haven't placed any heatsinks on the RAM because the adhesive that was supplied was not sticking them effectively. Ive put the new cooler/graphics card inside a fractal define r2 case, Im pretty sure I would not be able to get it out of the case again because Ive had to force it in!
My question is, are the RAM sinks nessersary, and can I do without them? The card didn't have any RAM sinks to begin with.
Sorry for the long winded question.
EDIT: I will not be overclocking the system.
If your using a full body cooler you don't really need the RAM heatsinks.It will be fine.
