Morpheus II Vs. MK-26

Hello all,

I'm playing with the idea of purchasing an aftermarket cooler for my GIGABYTE 1080 Ti Gaming OC. The temperatures with the stock cooler are acceptable, but they're not great by any means. It's overclocked to its maximum potential currently with a 120% power limit. My card will reach a maximum of 75°C during gaming with the overclock applied. That should tell you that my 1080 Ti is throttling, and indeed it does throttle during gaming. I really don't think my card will last for many years if I push these temperatures at this rate.

Can you slap these coolers on a 1080 Ti? If so, which cooler is better? I have plenty of room for it in my bench case, and I do not use any PCI-e slots other than the main one for the graphics card. I plan on using two PH-F140HP fans from Phanteks on them. I have these same fans on my CPU cooler, so I think having all the same fans would be awesome. Thanks for any help!

AMD 1800X w/ Phanteks PH-TC14PE (3850MHz, 100MHz BCLK)
G.SKILL 3200MHz CL16 16GBx2 (3066MHz, 14-14-14-14-28-42-4-6-24-1T)
GIGABYTE GTX 1080 Ti Gaming OC (2038MHz, 5940MHz)
ASUS ROG Crosshair VI Hero (BIOS v6301)

I put a Morpheus II on my Gigabyte 2080 today... huge temp drop. Should be a similar situation as yours. See post here for specifics:

@Advil000 Okay, thanks for the advice. Would you happen to know if the Morpheus can support 140mm fans? I'll be using the PH-F140HP fans from Phanteks. I know the MK-26 can support 140mm fans.

Does anyone happen to know which of these two GPU coolers performs better?

The clips on the Morpheus are for 120mm fans, or fans with the same fan hole spacing. You could technically mount a one of those round frame 140mm fans. The cooler itself is like 250mm long, so a pair of 140mm fans will overhang more than a bit from all sides. Also, the way the cooler gets mounted on the card there is not much clearance to the motherboard. The 120mm Cougar Vortex fans I have on mine end up touching my motherboard's heatsink, preventing me from installing larger fans.

Both coolers should be comparable. If you really want to use large fans go with the MK-26. Keep in mind that even 2x120mm fans will be far better than the crappy stock fans on your GPU.

What he said.

I didn't even realize the MK-26 was still around.

Personally I'd go with the Morpheus II which is a lot newer design than the MK-26 from 2014.

The other thing I did was pick the bare nickel plated finish. Reason being if I get brave enough to put the liquid metal on for a few more degrees it's got the best surface for it. I have no idea what the black coating is or what is under it.

But if you do get the MK-26 please take a few pics and report back! Someone has to be the guinea pig or no one learns anything.

I thought the only vga coolers still in production were the Morpheus and the Acceleros. In any case, I should have a Morpheus arriving today for a 1070ti as well, one thing you should check is the PCB design. If the gpu itself sits closer to the video outputs, you might have issues with clearance. AFAIK it fits on reference 1070's and 80's, if the Gaming OC is a reference one you should be good.

Well, what do you guys think? I really don't know. I found the following link that compares the two GPU coolers in what seems to be a very thorough and detailed test (more test details on next page too). I'm definitely set on getting 140mm fans though. I want my system to look absolutely bonkers with the amount of 140mm fans it'll be equipped with. I'm going to use the extra brackets and accessories my CPU cooler came with and throw on another PH-F140HP on my CPU cooler too just because.

Please check out my photos below. If I go with the Morpheus II, do you think the 140mm fans will even clear my SATA interfaces and the chipset heat sink? Also, would the PH-F140HP fans only be hanging off one side of the Morpheus II, or can you center the two fans towards the center of the Morpheus II so it doesn't look as bad (so that it hangs off a bit on each side)?

@Advil000 I'll definitely take some pictures and show what I did to get it all assembled. That's if I can make the decision on one or the other!

PS: The cheapest I can find the MK-26 is for $40 total. The cheapest I can find the Morpheus II for is $68 total. If I'm stuck having to go with the MK-26, I wouldn't mind at all given the price difference even though it's slightly inferior to the Morpheus II according to the reviewer linked above. I've read some forum posts here from members that stated they're very close in performance anyways so I don't know.

MK-26 looks very thin compared to the Morpheus. I can't believe they get similar results.

I've got a MII on a 1070. I believe 140 might end up to be louder in this use. Your problem with cooling is keeping VRMs cooled. GPU is not a problem, mine goes 42° max. I imagine I could run it passive and still get a good temp with caseflow. Only the board really need fans.

Speaking of VRMs, did you manage to mount the larger VRM heatsink, or had to settle for a bunch of the smaller ones?

140mm fans may not fit. As I wrote earlier, the 120mm fans I have on my Morpheus already hit the chipset heatsink and even cover all of the SATA ports. If you really want to be able to mount 140mm fans go with the MK-26. However, that heatsink is slightly older so look out for compatibility issues.


Both heatsinks have 6 heatpipes. The Morpheus is longer while the MK-26 is wider. Both are comparable in performance, but adding different fans will make a difference. The Morpheus is very easy to mount compared to the Arctic Cooling units I have used in the past.


As for the VRM cooling, it's a bit of a problem. 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.
