Hello,
im looking for some advice or experience on the MMCP, which is covering the PCB on my GTX 980 Classified. I am about to install my Morpheus Core Edition on the GPU and cant decide what to do with that plate, leave it or take it away.
 
Atm i think i am gonna put the heatsinks on the Plate, as direct as possible over the mosfets and memory. I suppose the plate will be pretty hot, especially over the mosfets and as long as something is hot, it will work to put a heatsink on it, right? :)
 
I will use a piece of copper plate (0.3mm) for the VRM Mosfets and the small Aluminium heatsinks that were included with the Morpheus over the memory chips.
 
 
What do you think? Do i need to remove the plate for direct contact? As long as the heatsinks will bring a few degree less temperature i would be happy. I suppose that the pads that EVGA uses between the chips and the plate are decent enough, same goes for the contact. At least thats what i hope.
 
For the case i take the plate of, i would have to use my own Pads and i dont know if they are good enough. Bought them in a PC shop, it was the only piece available, 80x80mm with 0.3mm thickness. Pretty cheap, 5,95eu from "Akasa"
 
next problem with the mosfets on the classified is, they seem to be double lined...14 mosfets and each one having "a little sister" a few mm next to it. So i cannot use the Aluminuim VRM heatsink given with the morpheus, which seems pretty nice. I would screw off the black pins and just fix it with the pads. But like i said, its not 1 line of mosfets, but 2.
 
Someone can share some own experience maybe?
 
 
thx and greetings from Germany

    I don't see how the cooler is going to fit since it's only compatible with the 650, 650Ti, 660, 660Ti, 680, 760, 770, 780, & 780Ti.

    Morpheus Core Edition is going to fit. The 4 holes are the same size (distance) as earlier cards.  Atm the Morpheus is still attached to my old card. But i already saw and read about some mods with the Morpheus. I know, when you look at the compatibility list, it only shows up to 780ti. Dont know why, maybe they havent updated the info yet or the problem lies in the VRM Cooler, But the cooler itself should fit...
     
    If it does not i will have a sad christmas....

    I'd just put the heatsinks on the plate if they will fit.

    Heatsinks on the plate? This could get interesting but I don't see how it could hurt anything unless there are clearance issues with the added thickness of the plate.

    I dont see any danger in putting it on the plate at all. I just dont know if it is as effective as the usual Morpheus-Surgery.

    I think you'll be fine putting the heatsinks on the plate although I've never seen it done before plus keeping that plate will help to keep your video board from sagging.

    if you look at the plate, right over the 14 Mosfets, the layout is a bit unfortunate, theres only a small stripe really covering the VRMs, because theres a cutout to the left and the right, only a tiny piece of the plate left to spread the heat. So i expect this piece of the plate to be the hottest, it might really work well to just put the VRAM cooler on top of it with very thin Pads. The memory shouldnt get to warm anyway. I will have to use the touching-method to find out if it works. As long as the attached pieces suck some heat and get hot it worked out i guesss...
     
    what do you think will happen if i lift the plate? Will the pads under still be intact and ready to use or will i have to replace them because the contact is broken and they are not sticky anymore?

    IDK, I've removed these plates to reapply TIM to the GPU when necessary but never used new thermal pads during reassembly. I never had any problems using the old pads again but someone else may disagree with me.

    depends on spacing to gpu an rest block ? or air cooling
     
    can use non-conductive TIM paste for broken pads

    I would just leave it were it is, looks like the airflow should be good enough
