The Official MSI GT73VR Owners and Discussions Lounge

it's Grizzly Kryonaut and it was the worst paste I ever used.

 

There are a lot of good reports from other users of Kryonaut, maybe you got a bad batch?

 

Liquid metal then.


Kryonaut works really well with high pressure desktop mounts like my NH D15 mounted on an X99 platform. However with low pressure laptop and sometimes not very flush heatsink, Kryonaut will perform very poorly.

 

maybe, but I won't ever try it again, nor any liquid metal paste

 

So which is your go-to paste? IC Diamond?

yes

 

So, what's your experience with the time between re-pastes with ICD? Or has it had a long life for you without needing repasting?

 

I personally just use a dot/pea method since you're putting it directly on the die and not on an IHS.

 

When you have pulled off the heatsink after that kind of application, what is the spread / coverage area that method provides? Does it keep the paste from reaching the edge of the die?

 

I never had problems with ICD to be honest, put it and forget it until some users here said that it dries off quickly which is surprising to me and HIDevolution Tech Support said they never had issues with it

 

Well if you noticed how machines/assembly line applies them, they just put a ton then mount the heatsink.. thats why you see it caked up when you take it off or rather have a ton. If you just put the pea/dot method.. as long as you keep pressure on the heatsink when you do the 1 2 3 4 screw in.. it will have an even spread. If by any chance there is a tiny uneven placement.. the extra paste will compensate for that. I haven't done it to my GT73VR.. maybe when I'm bored I'll do it but on my GT72 I was getting higher temps with the stock tim then when I replaced it went down drastically and under stress test @4.1GHz never went above 75C.. and thats on a rushed up job using MX-4 lol

You really dont need a lot at all since its on the die directly (just like old CPUs w/o an IHS) and then the heatsink sits on tops of it and spreads it out evenly if done correctly.

 

Thanks, that's very helpful

I've always done the even thin spread, and then cut a edge ring around the die carefully removing about 1/16"-1/8" of paste to leave a border around the die to seal against the air - no paste touching to the edge of the mating. It's worked well so far.

I'm thinking the pea method might just do the same without the extra effort

The pressure spreads the paste but with the right sized small amount the paste doesn't squeeze to the edge. Accomplishing the same effect, no paste exposure to the air on the edge.

That's why I was asking about the coverage you saw after removing the heatsink, after doing the pea method. But, it sounds like you did it and haven't needed to go back and redo it since it worked so well the first time.

 

No, its is Grizzly Hydronaut, its a different one

 

I just re pasted my freshly built desktop yesterday as I was getting some uneven core heating, I had done the pea method with some TX-2 and the pea may have been off center or I may have applied the pressure unevenly but it didn't spread properly, I wish I had taken a picture. I then re pasted with some MX-4 and I spread a thin layer on the H212 to fill the cracks and put a slightly larger pea sized dot on there. I'm still having thermal issues and am beginning to wonder how much of a different the paste makes.

 

Yeah I guess it depends on the setup at the time. I remember doing a paste job last year with an even spread/plastic bag method and it was a real thin layer. When I started stressing the CPU it would hit 80C+ when that method worked for my 4770K so I always kept my CPU @3.6-3.7GHz because it would heat up a lot at 4.0GHz+.. repasted using pea method and load was nice at 60C~ 75C> stress @4.1GHz no prob.

If the CPU is like the desktop I check out how the die is placed and sometimes do a line method but for me personally the pea method has been my default nowadays. But again this has an IHS.

 

Read one more time @Phoenix *HYDRONAUT* is the lower end thermal paste from GRIZZLY On level with NT-H1 and Mx-4. Put it in nearest trashcan and not on your hardware

 

I remember @Mobius 1 comparing stock thermal paste to semen

That doesn't seem to be the case for the GT73VR from what I've read in this thread, am I right @hmscott ?

MSi is one of the better ones.

Though, their heatsinks being massive helps too.

 

This method works the best: =) <-- smiley face.

Nothing beats the smiley face. Just don't make a sad face as you'll gain 10C.

LOL....with all kidding aside, all this dot, pea, line method is just silly on a laptop due to it being a lower pressure mount.

Just spread the paste and have an even (slighter thicker) layer than as you would on a desktop.

I do something similar to what @hmscott said below...

Great logic and thinking -AND- this works very well.

In addition to this, I also make a little mountain toward the center so that the pressure will disburse the paste outwardly / evenly when pressure is applied.

Since the CPU is more rectangular, I make a small mountain range length wise across the die, but make sure to not extend the ends all the way to the edge. Hope that makes sense.

ICD isn't the worst paste, but it isn't the best either.

ICD's perk and claim to fame is its thickness. That's it.

There are other pastes that are better if you're not needing the thickness.

There are two philosophies here:

1.) Use ICD to compensate for the gaps. Quick fix. = Not addressing the main issue in the first place in correcting the gaps. (leveling out the heat sink so that it sits even as possible with the die(s) ... )

2.) Fix the underlying issue of the uneveness so that one would not have to resort to using ICD in the first place. ICD is also looked down upon as an easy flat tire fix. You know them cans that pump foam into your tubeless tire.

To each his own, but ICD can be good for its very specific application, but it is far from being the best.

Also, most of these resellers are sponsored by ICD so there is obviously an incentive there to use it.

Best option: Return to sender, but put the return address to the local land fill. LOL .... This can be said for a lot of pastes.... *face palm*

 

Agreed. Also the thicker chassis and ventilation in the GT73VR helps clear hot air faster.

So what other paste is left?!

 

Does the method really matter?

 

Prolimatech Pk-3 and Phobya NanoGrease Extreme. PK-3 is a well known paste. And Phobya is also known for their Liquid metal. Both should be tested

 

Assuming you're referring to traditional paste? If so, Grizzly Kyronaut and Gelid Extreme.

But for your targeted application and need, you're needing thick paste so ICD is your only choice, unless you want to add peanut butter to the two pastes mentioned above.

Liquid Metal wise....considering that even contact is a must, CLLU, Grizzly Conductonaut and the paste papu had mentioned. All the LM's contain the same main ingredient, but have what makes them different are the other elements / metals in them that define their uniqueness. Hence, the conductivity numbers and variances.

 

Has anyone had the issue where CPU frequency and voltage show as "N/A" in dragon center?

How do I fix it?

 

Install Intel XTU. You don't need to do anything but install it.

 

I second this.... I would not use dragon center. Just use XTU.

 

Mmm, my temps are at least 8 degrees lower than with the stock thermal paste, so it´s better on my hardware than in the trashcan. Lm is better? Sure

 

Liquid metal.

That's on a desktop CPU with high mounting pressure and larger than TDP heatisnk.

We're talking about laptops here.

XTU is just as bad. I would recommend you set the values on XTU then just exit it completely by closing the window and right clicking the taskbar icon.

LM is the only paste able to provide a significant drop in temperatures with laptop heatsinks.

 

How much lower can it get???

By the way, after this last repaste, i had a really anoying noise coming from the cpu fan. It was a high pitched noise when in low rpm (around 1200). I have adjusted the two screws of the fan and the noise is gone. I think some people had this problem and returned his laptop, so here is the solution, you can give it a try.

 

Maybe you didn't tighten the screws on the fan enough when reassemble, so when you take it out to "adjust" you're only fixing the tension.


It really depends on the specific heatsink, I don't have a unit to test with LM yet.

 

Well the use of XTU and TS is the best we've got. I would still prefer XTU over the stock apps.

Also, I'll be LM'ing the GT73VR here within a day or two.... we'll have some data soon and see what this cooling system can do. I'm optimistic.

 

Maybe, I usually check tha all the screws are tight, but anyway, I´ve posted because I think it can be useful, it was driving my nuts, hahahaha. I will read about LM and the risks. I have never used it before, but all of you talk really good about it. Anyway, this is the cooler laptop I´ve ever had. when brownsing the net my cpu stays under 30...

 

Does MSI make previous bios and EC files available should I want to downgrade?

 

No....you have to keep the backup locally, once new version released, old version not avaiblable

 

I haven't updated mine, is there a way I could make a copy and post it?

 

What versions are you running?

 

What ever shipped back in September, The laptop is packed away but I'll have plenty of time starting tomorrow to check it.

 

Maybe the image of liquid metal is bad in my head because of how bad it performed on my Clevo laptops due to the heatsinks not making great contact with the CPU and made me not think so highly of it anymore

That, and the hassle of removing it / re-applyinng it

I am really lost here right now to be honest as to what to put on the CPU/GPU

 

Maybe just try the stock paste and then only repaste if you need to? The laptop is easy to work with.

 

I was going to say the same thing.

 

sounds like a plan

 

And I expect you run max what your silicon can handle. Higher wattage = Higher temp.

I stand on this... I would let HiD test a good ordinary thermal paste and as well test with Liquid metal. Then you have got confirmed that the Heatsink fit on die is good enough.

 

Are you changing the RAM below the MB?

 

Actually I tried ICD with my 6700k early last week, and it dried up after a week or so.

 

well my order consists of 64GB RAM so the RAM will be preinstalled. Why do you ask?

 

lolzzz, yeah, I tried ICD on 6820HK and dried in 2 weeks....

 

Well if they are installing RAM under the MB the they will be re pasting, so you wont have "stock" paste.

 

my guess he is asking because 2 slots are under the keyboard and to reach there, you have to disassemble the laptop, for sure remove all HS
