Ok so Ive been reading these forums for quite a while and Im soon going to be ordering on of the Zalman VF900 VGA coolers because Im not happy with A: the noise of the powercolor stock cooler, and B: the performance of the powercolor stock cooler.

I will be buying some AS5 to place on the GPU when I install it.

My question really is, would it be worthwhile me buying the seperate Zalman VGA RAM heatsinks? do I need them? will it really make a difference to overclocking possibilities?

You get the ram sink with the VF900 its self.

They are sold on there own for people who water cool and want the RAM sinks.

They dont really give you anymore extra overclocking potential but might aswel pop them on to keep the memory cooler.

The vf900 comes with ram heatsinks, so no.. there's no need to by even more

thanks for replies though.

The VF900 is brilliant. My 7900GT idles at 34 with the fan on minimal. Its silent, and provides excellent cooling. Make sure you got good case cooling aswell mind.

I've noticed a drop in GPU core temp, and I can overclock the core further than before, however not so sure of max memory clocks, being their is less airflow. It's MUCH quieter than stock fan, but like poster said you need more case airflow to make up for the lack of exhaust. Ideally front airflow, side and exhaust fans. Otherwise the hot air will slowly rise to around CPU and start cooking that. The clear fan exhaust in my system exhausts much more hotter air than before (was slightly warm, now warmer) I wouldn't fit one in a shuttle/micro atx case unless it's a cool running card. No updated pic of 900 probably do it later..

I'm looking at getting one of these for either my current 1800xt or potential x1900xt. How easy is it to get the old cooler back on again? Take it you'd just warm the Zalman sinks up to get them of? Also is the Vf900 itself easy to fit?
