If your card uses a stock PCB layout the large VRM heatsink included on the Morpheus will fit, but if it doesn't you will have to make do with the smaller heatsinks. For my card I had to use the smaller ones with tape. Temps. are worse than stock but don't seem to cause a problem.
That's actually good to go in my case. I intended to custom cool it from the get go, so I went with a reference PCB (MSI Aero) not only because the blower cards are cheaper, but also for the higher compatibility.

I used the large VRM heatsink but I still installed other heatsinks on the chokes and the components near to them. I had to stuck the large heatsink between the PCB and the Morpheus using thick thermal pads. It holds well and I believe it does some job. Alternatives to the large heatsink are bad because you can only use small heatsinks on the components where the large heatsink is meant to go. So if you have to go this route I would recommend using aftermarket copper heatsinks. They dissipate much more than the aluminum ones.

My method for mouting the large heatsink is pretty easy. I've seen someone else used a plastic tie going around the PCB.

Yeah, I've seen the ziptie method as well. Haven't thought about using pads to compress it against the main heatsink though, I'm assuming they sit millimeters apart then.

I used the thick thermal pads that came with the stock cooler. One strip between the heatsink and the PCB and then two or three between the two heatsinks on each side. You have to be carefull when you do the installation so it doesn't slip and move the small heatsinks.

Sorry for hijacking the thread yet again. I'm currently mid-installation of the Morpheus, and I'm brainstorming with a 3rd idea for the small components cooling. After disassembling the 1070ti, I see a full aluminium plate covering memories and the VRM set. Here's a photo with the blower fan already removed, also having side-by-side a rough idea of the Raijintek heatsinks I'd need to use.

Here's the problem: on the VRM side, while the MOSFET's are all neatly aligned, the remaining extra chips are a bit all over the place, so I'm sure I'd need extra smaller heatsinks for individual components. On the factory plate, that finned heatsink at the right is fixed to it, and not directly cooling any component. How feasible would it be to use the factory plate to cool memory chips and VRM's, with the Morpheus' fans directly blowing air on it? On quick testing, it looks like the Morpheus will fit with the plate in place, if I remove that finned heatsink (and judging by the 2 spots of black goop I see at its base inside it, it seems it's glued in, rather than welded).

Yeah that's what I did on my Xp. Got some pliers and ripped off the heatsink, but on my card there were two tabs poking up that I had to dremel off as well. I don't see those on your baseplate, so you should be good by just ripping off that heatsink. Also keep in mind that the Morpheus can sag a bit near the end so you may have to bend it upwards slightly.

VRM and VRAM temps will be slightly worse than going with the included heatsinks, but it's a lot easier to install and maintain. You might be able to find an extra cooler+baseplate on ebay if you want to revert to 100% stock.

Both the MK-26 and Morpheus II are good heatsinks, and both are dated designs, especially the latter. The Morpheus style heatsink was originally from the Logisys VC6006 Dracula which came out around 2005. Mk-26 is 2012. Only difference between the Dracula, M1 and M2 are the accessories and mounting plates. The Core edition is a powder coated + clear coat which makes the heatsink fins twice as thick, but does not hinder performance surprisingly. MK-26 black version was done right with electroplating.

Keep in mind that the review Herooftime posted is using the same 120mm fans on both coolers. The M2 doesn't officially support 140mm fans, and the MK-26 is wider to accomodate the width of a 140mm fan. Because of that, the 140mm fan will utilize some more surface area on the MK-26 which should drop temps a bit more, though it's still going to be really close to the M2 overall.

The Gigabyte 1080ti gaming does not have a baseplate that covers the VRMs, but does have a VRAM baseplate. You'll have to use the included VRM heatsink to cover the mosfets back there.

They are both decent but have endless compatibility issues due to heatpipe clearance of components especially VRM. Morph is 120mm MK26 is 140mm. When installed they take about 4 slots + 1 slot for intake space. On top of that you have to sort out VRAM and VRM cooling... It is better to buy a beefier heatsink GPU right away than to pay extra for aftermarket and DIY it. Considering prices, some people opt out to go hybrid instead and it's easier to install.

What is the best RTX 2080 for using with Morpheus II? I figure out the stock PCB with stock fan headers (FE for example) is not good, because its header is not standard (fan+RGB silly design).

Well... I've seen 2 different cards taken apart.

The EVGA cards might have a sub-plate for cooling at least some of the board components that can be left on.

On the other hand, Gigabyte has the easiest total disassembly of all of them. About 7 easy screws on the backplate and everything comes off.

As for fan headers that's going to be a problem on most of them. I just plugged the fans into the motherboard and set the fans to ramp with MB temp. Why? Because I can control the fan speeds in general by setting fan curves on the MB. The cooling is so good As long as the fans are running at any decent RPM at all the card won't reach 60C. It doesn't have to be rocket science. Any why put the fan power load on the graphics card connectors if there's no point?
