Raijntek Morpheus II + Vega = hotspot problem

Stop your griping and sell the gpu.

I've finally got it God damn, it was so hard to do this simple job.
I'm sooo happy, though something is wrong with fan speed now as both fans runs at highest possible speed all the time (Be-Quiet Pure Wings 120mm 2000RPM), though they run at 550RPM in idle before and I haven't changed fan curve/profile. Need to check it, maybe a restart will fix it, but at least I don't need to disassemble the heatsink for fixing it and in worst scenario I can connect them to the mobo. Cheerz



I've used Arctic Cooling MX-4 and as told before used about 1,5-2g paste spread on entire chip, quite thick layer. Then I've reassembled the biggest heatsink for VRMs with new thermal tape and started to screw the card onto Morpheus with 2 screws (until they stopped) which are farthest from the PCI-E slot and then other 2 screws (until they stopped) which are closest to the PCI-E slot and then tightened all in a cross pattern.
I've used stock X bracket, Morpheus screws with springs without plastic mylas. Hope this will help for someone who had same nightmare as me.

The card stay with me but when it struggle again or the performance will not be enough I'll go NVIDIA. It's been too bad experience to trust AMD GPU anymore. Thank to you everybody once again.


The problem with fans has been fixed. It's working awesome now. 1st fan is a 3pin fan and 2nd is 4pin PWM. I've done a small mistake and connected 3pin fan through a 2 to 1 splitter to a connector with 4 cables and PWM fan into the splitter connector with 3 cables.

The whole Vega graphic card lineup is an evil lineup to deal with, or something is really really wrong with the card or with the cooler itself. It's a hopeless card, so far... ZERO ENJOY.

I've refitted it 10 times now, and still can't get this shit to work. I've changed thermal paste from Grizzly Kryonaut to Noctua NT-H1 (applied a little bit more paste as per some tips) and the hotspot temp went down from 105-110C to 95-98C at its highest. Sometimes, while playing CS GO in 1440p hotspot went down to 75C for 2-4 seconds and then back to 95-98C in just 1 second. I haven't seen so much throttle though, but clocks varied from about 1210 to 1360MHz. The same was in Unigine Heaven. All other temperatures were at 60-65C. Then... I've underclocked P7 to 1100mv and P6 to 1050mv, raised power limit to +50% and... hotspot temperature went up to 110C in just 1 second and stayed at that. I've also tried with the Gelid GP-Extreme Thermal Pad 1mm 12W/mK and temperatures looked exactly the same as for the Noctua NT-H1 thermal paste, with an exception for 4-5C higher temperatures other than *hotspot in stress*, in both idle and stress.

I don't know what to do next I'm sooo pissed of because of it. This card is an expensive story and waste of time. I've got it for 200$, but could rather buy a new RTX 2060 with an aftermarket cooler instead of the Vega crap, Morpheus II crap + fans, couple of thermal pastes, thermal pad, new screws with springs and plastic mylas imported from Raijntek in Germany. I've already spent about 340$ dealing with it.

I've bought Arctic Cooling MX-2 and MX-4 pastes for testing as the price of them were under 1$ per gram and I think I put whole 8g MX-4 tube on the freaking core to sink it in and say bye to the card and go buy NVIDIA instead. It's starting to go on my nerves. It's the last AMD GPU I've ever bought...

If it is a reference Vega 64 I would have no issues taking it off your hands. That way you could get some money towards whatever card you want.

Had exactly the same problem and I sorted it out also in combo Raijintek Morpheus 2 + rx5700 (bios mod to XT), so i´d like to share a little "how to mount Morpheus II + rx5700XT", because both cards are very similiar and I guess you can use the same method on both of them
btw: Due to binning my rx5700 is performing little worse in terms of temps than a true one

1. Buy "push" fans, that are able to push the air through the body of Morpheus II - I have 2x 120mm Noctua 1700 redux
2. Buy some thermal paste that is on the thicker side - I used MX-4
3. Buy some silicone and plastic washers


Washers are very important - they will not only increase the mounting preassure, but thanks to the flexibility of the silicone, they will also sort some of inaccuracies in pressure.
Something like this:

And now to the mounting:
1. Use more paste than it is recommended by Linus and other youtube gurus (for rx5700 I used about 2 drops of the size of the pea) and spread it evenly, dont use "drop in the middle method" - the process of cooler mounting will screw that up and make it uneven
2. rx5700 core is very small, so the heat transfer from something that small is complicated. So use thermal paste also on the metal square (i dont know what its called) around the core - Morpheus´s contact plate is big enough to have contact with this part as well.
2. Avoid using the back mounting bracket that came with morpheus II - if you have one, then use original one with a square hole in the middle and if you don´t, than pull of the rubber cover and use thick thermal pad instead - the rubber is to hard and could destroy back of the core.
3. Now to the washers - put them between the back mounting bracket and the head of the screws. I wont tell you how thick and how many, because i learned, that different types of rx5700, vegas and VII´s have different hights.
4. And now probably the most important part: Count how many times you turn each screw. if you dont, youll end up with uneven mounting, which is the cause of 110°C + hotspot.
5. And obvious - do not overtorque the screws

So to the conclusion - Washers + counting how many times you turn each screw are the key.

My max temps after 1 hour of playing Witcher 3 on max with 100+fps (Fans are running on 60% or so) :
Gpu: 66°C
Memory Junction: 78°C
VR VDDC: 63°C
Hot Spot: 85°C
VR MVDD0: 52
VR MVDD1: 50

PS: I wont share any pictures - I panicked, when i saw 110°C hotspot and my card looks like an abomination littered with aluminium and copper heatsinks.

Reading that you finally fixed the problem pasting the chip with a thick layer thermal mud. I was sort of curious why it needed a 'thick' layer. Could it be that the HBMs and the GPU are at different heights? Or could it be the 'short' corner on the HBM side offset the 'X' bracket.
Hey, not because I don't like playing with mud, I've done some pretty muddy jobs, Lol. Most I have say is, good mud's pretty forgiving stuff.
Years before, I had problems mounting a gpu water block. I found out some AMD HD7950s had the gpu chip seated lower in the die ( or the die was way taller than the chip). So the cooler sat on the die, not the chip.
I solved the problem putting a copper shim between the chip and the cooler head. This way the water block sat on the chip without contact with the die. Yeah, That was a headache centering the copper shim on the chip so it didn't touch the die. I ended up trimming the shim as close to the chip's dimensions. Had mud on both sides of the shim so it was a real slurry job.
The reason I trim the shim was I wasn't sure the gpu, copper shim, die and water block had proper ground, that one would short and fry the board. I got a small box of that junk in my closet for that stuff.
I've also got a Raijintek Morpheous 2 for Vega64 sitting in my closet. After owning it for a year as my next project, I've been reading up and watching videos to make sure I get it right, too. I don't wanna get a larger box for my 'junk'.
I'm glad you guys started this post. Can't thank all you enough.

Do you have a reference Vega 64? I thought the VRM heatsink didn't fit on the card. So you used the x bracket from the original cooler with the screws from the Morpheus, correct? Did you apply all the heatsinks or just on the mosfets? Any info would be appreciated I'm trying to lower this hotspot temp.

Last February I finally got the Morpheus out from under my bed and installed it. I got tired of the Covid kids staying home beating up all us regulars on CoD WW2. Well, that became a weekly learning experience.
At first I was able to achieve fairly good clocks @1750 mHz and temps @ 35/40c. I thought this was sensational so I started fooling around with it some more, driving the clocks up to 1800mHz. It couldn't believe the performance. But alast, all was not stable.
I was seeing... and that's about what it was. Black screens to the desktop/freezing and the crashing secrets of VEGA-Morpheus 2. I seen temps rise past 82c before I shut everything down. And went back to the Sapphire64 stock clock setting @ 1635mHz and started over again. Now the highest stable clock is 1700 mHz till I can find the problem.
At Mem 1085 mHz (still a little low), pwr @+37, it's barely pushing 40c with the power limit +50% and temp @ 85c. Fans are 95%
This is my budget rig

Alphacool GPU copper ram heatsinks 6.5mm x 6.5mm (1pks)
Gennel thermal conductive glue 10 grams (Do not use this glue as thermal mud for CPU or GPU)
I'm looking to upgrading the UPS. It's a little lower than my psu output. It's kinda regulated me to play games with lower gpu settings.
My rig is so budget. I bought a discontinued case and used the thermal mud that came with the Raijintek Morpheus. I also use Gennel Thermal Conductive Silicone Plaster to attach the smaller heatsinks into place. I had to shave the tops of the SD ram heatsinks under the Morpheous GPU bracket as they were too tall to fit. It's nice to have a Dremmel tool.
I use a razor blade to spread a thick, even coat of mud across the gpu and HBM2. Judging from everyone's experience of getting the heatsink on the gpu was a ceremony of hit and miss. I consider myself lucky to re-install it twice.
You guys are the best. Thanks for all the info you guys produced on this thread. It helped me get my Morpheous 2 in decent running order.
However, I did buy premium heatsinks to replace the thermo strips on all board compliments (like MOSFETS, ). I'm sure it didn't make much of a difference but centering and pasting the GPU did.

Hello. I tried the stock xbrace with my Morpheus cooler and it was so much pressure it shattered the silicone killing the card maybe with a bolt and nut to carefully tighten the xbrace to the card. I'm going to buy 1080ti for 700 dollars in the gpu shortage and cry my eyes out as I play all my games with higher fps and no crashing. Officially team green for life. I wish I gave up sooner and sold it while it was working
