GTX 470 SLI Heatsink/Fans

Ive got 2 GTX 470's running in SLI. I have a water cooling loop that I've researched and is all good to go however its going to cost me about 800 for everything which isn't exactly in the budget right now... could anyone point me in the right direction for some good aftermarket bolt on fans for these cards so I can keep them at a decent temp in the meantime?

probably not worth it, very few after market air coolers will run well in a SLI config, you might aswell put up with the hot temps until your water cooling loop is ready.

I had 470SLI for a while and it was just too hot (and more power than I needed). I much prefer having just one card because I can slap a 38mm Delta on it without having to worry about space
