    EK eVGA/XFX 790i Chipset & Mosfet Waterblocks

    Does anyone know if EK's current blocks work on the new reference 790i boards?

    The SB hole spacing looks like it hasn't changed from the 780i...which means there is an EK solution for that. Not sure about the NB and Mosfets?

    The NB will be simple chipset block...
    The Mosfets will have to be different, special made...

    Do you need any measurements for the Mosfets and SB blocks? Or can you verify that there is something in the works?

    The NB blocks dont have much space...
    So if you have about 1/2" tubing it will ba hard to mount the compression fittings.

    I have to tell you that till now we have made 3 blocks with measures from another guy and 2 of the blocks did not fit once we made them so we had to repair them or even have to made new parts.
    It was S-MAX block and MAX-EX block. So we have decided to make the block only when and if we have the hardware in our hands.

    That sounds logical ... but I do hope you're able to get one of the 790i boards, as many of us would love to have EK blocks. Actually even more interested in a waterblock for the 9800 GX2. If we didn't have the distance/customs issues to deal with, I'd gladly ship my motherboard and video card to you to use for your measurements and testing!

    Nice, what about 790i NB blocks? I know you said its a standard chipset block, but by that did you mean one of the current chipset blocks you make fits it, or that it will just be a standard single chipset block when you make it?

    Really looking forward to the 790i NB/Mosfet blocks.

    The 790i NB and SB will not be a problem.
    The mosfets could be made very soon after I get the motherboard.
    And as soon as we find space in the capacities...

    The good news is that BOTH the NB and SB hole spacings are the same. As you can see from the pics below both are ~5.5cm apart.

    NB


    SB

    the NB is still different though. There is no second chip for that 780i block to cool, I dont know if that will be an issue as the block was made to cool 2 chips and the 790i only has 1 for the NB heatsink/block to cool.

    We have a winner!

    Based upon my measurements I sent a message to Eddy for clarification. He said that the NF4 rev1.1 has a fitting range from 49,5 to 60,5mm so it will fit both the NB and SB chips.

    Note, the NB/SB 1 will NOT fit b/c it only measures 53mm. A minimum of 55mm is needed to work.

    So...all we need are ViperJohn's Heatsinks for the mosfets or EK mosfet waterblocks and it's a rap!

    hey guys, been running this board over the weekend now and I wanted to let you know some things...

    priming for HOURS @ 450 FSB, the NB/Mosfets don't even get warm! they are cool to the touch

    this chipset doesn't have the heat probs the 680/780 did and I'm thinking watercooling the board is seriously unnecisary.

    these GX2s on the other hand...

    Does anyone know for sure if the MCW30 will work on the NB/SB? It sounds like it would, but I want to be certain.

    Also, are there any mosfet solutions yet? Thermalright? How about these?

    The MCW30 will physically mount on either the SPP or MCP of a 790i with some "buts".

    On the SPP you would still need a mosfet cooling solution and my Vcore mosfet heat
    sinks for the 790i are not available separately.

    On the MCP there would be no water tube clearance, even with 5/8" OD tubes, with
    air cooled GFX cards that use a two slot cooling solution.
