Then using a computer it tells the arm above the reflow board to melt/suck the solder at set vectors on the board. Then after the board is cooled the port will be able to be pulled out.
There are a few problems he highlighted to me about my theory of removing one port.
Due to the way the twin dvi ports are set up there is no way to remove one without the other unless you are willing to cut through the mounting plate.
The mounting plate is a large plate that bridges both dvi ports together and is soldered directly to the board. This plate is used to stabilize the port otherwise it would just flop all over the place. It is also where the standoff's are screwed into when you screw in your dvi cable.
The plate can be seen in the following photos:
Here is a picture of the soldering welds for this plate:
He mentioned that there is less risk that the card won't work if the primary DVI port remains intact, but other than that he would not speculate further on other topics surrounding the BIOS of the card. So he has left me with a few options to think about as follows,
1) Cut the port out leaving the first port entirely attached. This includes cutting through the support plate. Not an easy cut even with tin snips, best bet would be laser cut.
2) Remove both ports, cut the support plate and reattach the first port.
3) Remove both ports and hope the bios of the board doesn't notice.
4) Remove both ports and use a donor single DVI port from a nvidia card (I have a 280gtx that would work for this). This will conserve the stock ports should they ever need to be put back for warranty purposes.
I'm still thinking about it and will make a decision soon. Either option 3 or 4 look the most promising but understandable that option 3 would not work for most.

You can connect it via USB directly to the motherboard, via aquabus to an aquero 5 front panel or just to a fan header on the motherboard.
If you go the usb route you can watch the flow rate in real time using their application, set up monitoring and so forth.
If you go the fan controller route once configured with usb you can set your motherboard to shutdown if the flow stops.
has some of these coming in (Sergui sent me an email late last week) if you're looking to buy them in AU.
In other unrelated news, ordered a crimping tool from MDPC-X
this morning which has shipped. Apparently the best
crimping tool in the business.
In the meantime I'm currently using one of theseEdited by soth - 10/22/12 at 1:57am
