Question About Cooling Memory on GTX 600 Cards

[Leyawiin]

I have an Arctic Cooling Accelero Twin Turbo II that I've bought and never used. I was thinking about installing it on a GTX 670 with half its memory modules on the back of the PCB. The instructions of course show how to install heatsinks on the front RAM, but I was wondering if I should leave the back ones bare or not. I have extra heatsinks and could do it, but if there is no direct fan blowing on them would it help OCing the memory? Would there be any harm in doing so?

you can leave them bare..

If you have the extra memory sinks tho.. u should go ahead and do it.
You may have some problem with the adhesive on the tape securing to the memory.

And yes u dont need a fan over it... if the sinks are good, they can do enough cooling ambient temps inside the case.

However adding a tiny fan would improve it.

Install the card, set the clock rate if overclocking, run benches and touch test the memory (or probe or laser meter). If it is not painfully hot, it does not need heatsinks, or vice-versa. You'll probably hit a clockspeed ceiling before a heat induced ceiling, I mean there probably won't be enough difference to matter unless you're modding the card for higher memory voltage.

Thanks guys. AC uses some sort of removable thermal "glue" now (you mix two packets), so they should stay put fairly well. I used this same cooler on a GTX 460 and it was fine (that's why I had some leftover heatsinks). I'll test first, but may go ahead and put them on the back modules. Sounds like it couldn't hurt.
