Also, the coolers largely obstruct the fan connector on the cards and the fan connectors are 3-pin (the board supplies 4-pin) so you'll need to connect the fans to the motherboard or something.
no need just put the cable this the original connector, take the plastic off the wire, double them and insert them on the Zamlan connector holes the apply duck tape, and if you get a fan that have 4 pins is even better
True, you could do this. But it does mean cannibalising the stock coolers. Also, I don't think the card will be able to control the speed of the fans after doing this but I could be wrong.
Whacking them into the motherboard was an easy solution for me because I had two 3-pin fan connectors on the board not in use anyway and the cards only need minimum fan speeds with these coolers (temps are 64C and 49C respectively, the hotter card is taking in air from just behind the cooler card).
I'm sure you could get a 4-pin molex to 2x3-pin fan connectors adapter and use that too and use the fan mate 2 which comes with the Zalman VF3000A to force minimum fan speed at all times.
