What is the maximum speed you use TY-143 fans at on MK-26? I'm guessing about half speed is more than enough.

If you are using more rpm than that your case is probably not supplying enough cool airflow to them. 2x TY-143 2500rpm 130cfm each is 260cfm of airflow through the MK-26, so case intake fans need to be flowing at least that same 260cfm to them (plus whatever airflow your CPU cooler and any other component coolers are using) .. at a guess your case needs to be flowing ab out 400-500cfm to be able to supply cool air to components.
(I have found cases usually need to flow 120% to 150% more than component airflow to receive air less than 5c warmer than room when all components are at 100% load)


You might find below link to how airflow works and how to optimize case airflow of interest.

This is the fan curve I'm using. Realistically, since temps are so low the fans never exceed 60% speed. Thanks for that link! Very interesting read.

Yeah, having those TYs at full blast is probably not doing much, except maybe being very good at blowing heat away from the VRMs. The TY-143s on my NH-D15 "cap out" their cooling capacity at around 1500rpm. Going any higher does not cool any better at all. This is with two PH-F140MP at full blast. Adding a third or fourth intake fan "unleashes" the TYs.

Because the limit is not airflow but getting heat away from dies and getting heat away from transistors to the heatsink through the die. Many large coolers are cold yet your core temperatures are high, the bottleneck is elsewhere and not in fans or fin area.

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.
this article (https://www.hardwaresecrets.com/prol...oler-review/7/) has the MK-26 beating out an Arctic Accelero Xtreme III by 5°C in temperature delta,
an Arctic Accelero Hybrid by 4°C and a Gamerstorm Dracula by 3°C (this last is very similar to the Raijintek Morpheus).

The Gigabyte 1080Ti Gaming OC has a portion of the heatsink that contacts the MOSFET's through a thermal pad. My Gigabyte 1080Ti Gaming OC fried after replacing the stock heatsink w/an Accelero Extreme III, I had glued heatsinks on all the MOSFET's and some caps. A component on the backside (which I have yet to identify) of the PCB blew on boot (i.e. when not overclocking).

One of Doyll's recommended fans. I have one that I've never been able to use because a noctua NF-A14 ippc3000 fit better w/my phanteks phtc14pe.

I might be using a custom VBIOS, and I'm eyeballing the Palit 350W VBIOS after getting this cooler situation sorted out. I took pictures of the stock cooler and made sure that I'll be cooling exactly what the factory heat sink was cooling too. If it's not clear using just this picture alone, see my previous post a few posts back and see where I've placed the heat sinks in the other picture to get a better idea.
Here's the part that blew, it looks like a transistor since it's a three terminal SMD.

With the card pushed harder, (2.1ghz/1.093v) it still never exceeds 50C (at 24C ambient).
Those are amazing temps for a 2.1 Ghz. overclock. It takes me 1.181V to get to 2152 Mhz. and that throttles if I exceed 63°C. I wonder if you could get to 2.2 Ghz. at higher vcores. The airflow you're getting over those copper heatsinks on the VRAM probably provides secondary cooling to the GPU as well.

Does the backplate of your 1080Ti AMP Extreme have any thermal tape between it and the PCB? I remember my 980Ti AMP Extreme didn't.

It's a shame I never got around to updating this thread with my results. If I can, I'll come back another time with an actually detailed post.

To summarize my results, I got around to slapping on two white Phanteks PH-F120HP fans that I had purchased from Phanteks. They come with the PH-TC12DX cooler, but I got the fans separately from the cooler for a cheaper price thankfully. I won't go into detail what I covered with heat sinks. I will go into detail (with pictures) as to what I covered with heat sinks later. I assembled everything together and run the fans off of the motherboard's fan headers. Fan speed is set to auto, and they rarely exceed 1000RPM. They're much quieter than the small triple-fan setup that the stock GPU cooler came with. I genuinely cannot remember how much of an improvement I noticed in raw temperatures, (I will give exact temperatures later) but they rarely exceed 60°C if I remember correctly.

The following is what made me happiest the most. Stock coolers are much more of a drawback now than ever before (if you have a lower end flavor of whatever GPU you have). GPU Boost 3.0 throttles the GPU heavily due to high temperatures. Without touching anything else and simply slapping on the full new cooling assembly, my core overclock went from 2012MHz to 2038MHz (two bins). I was finally able to finish off overclocking the memory too and stopped at 5940MHz. Of course, my 3DMark score went up but I genuinely can't remember by how much it went up when I was doing all the testing. It's been too long for me to remember such small details. Like I said, I'll try to gather up all the information I had previously and will share it all at a later date. I can definitely confirm everything stayed absolutely stable. I do not experience crashing whatsoever in any game that I play, on top of the countless hours I put into making sure it's stable like this.

There's two major issues that upset me about the assembly. Not enough full-size heat sinks for the memory chips, and the full-size heat sinks not fitting under the heat pipes of the Morpheus II in the first place. I had to file them down two to three millimeters in order for them to sit under the Morpheus II's heat pipes when mounted to the GPU.

EDIT: Just ran 3DMark and GPU temperature peaked at 63°C. Max power drawn was 316.5W (127% of 250W). Will update with gaming results later.

EDIT 2: Played PUBG for over 1.5hrs and attached a picture showing peak values for temperature, power, clocks, etc. I was watching which bins my GPU was sitting at when I was playing PUBG, and I can firmly say that it was staying at the top two bins (2025MHz, 2038MHz) 95% of the time. Fan speeds show peaks of 1,225RPM and 1,207RPM. I genuinely never noticed them get up that high, but HWiNFO doesn't lie so there you have it! They must be quiet regardless.

Thanks HeroofTime for posting your results.
So, are you happy with your two white Phanteks PH-F120HP fans on cooler?
