That's a card cooler - it may also help with overall cooling if there is a side vent that it can draw from, but it's main function is to direct airflow to tightly packed cards, or to operate in tandem with some of Zalman's "fanless" coolers.

The alternative is expansion slot extractors (like the Akasa listed on the same page) - beware though some take liberties with the "single slot" form factor - or maybe the cards next to them do, so that they will NOT fit between two cards.
Also, some slot extractor fans clog up very easily - I was pleased to find a slim one, but the idiots used blades more like a fan than a blower, so it tended to pack itself full of muck.

I'd check for a front fan mounting position - a lower front intake fan not only gets the air moving in the case, but brings fresh air in - something that Zalman will only do if there is a side vent.

Thanks.
Yeah. True on that circulation issue. I have a fan in the back of the case, that sucks out air.
What I need, is some flow over my V2-Sli setup.
I am planning to buy some low profile heatsinks for the cards and glue them on the chips as well.
Probably get a fan for the front of the case and have it running slowly to get a tiny bit of cold air in.
And then mount that card-fan as well.

Many, many people have used V2-SLI setups without having to buy expansion slot coolers.

I use these http://www.xlr8yourmac.com/voodoo2/coolers/ but they aren't exactly easy to find anymore.

what are those types of coolers called on the first post? i've been looking for a type like that but when I search I just get slot coolers.

I don't think they have a name other than the product number.
They are made by zalman.

I know... V2 no need for fan.

On the other hand, I like cooling and for me, the V2 in SLI runs just a bit too warm.
I really wan't to lower that temperature a bit, and possible prolong the life of my V2's.
