[Liquid Metal Showdown] Thermal Grizzly Conductonaut vs Cool Laboratory Liquid Ultra / Pro

Most likely a heatsink with uneven contact with die. Liquid metal will never work as expected if the heatsink isn't in good condition and with good fit on die.

 

Just opened it, one screw got loose and lm paste got dry and really thin, but it looked fairly even, exactly as outstanding initial results indicated.

Did i put too little of it? Or do you think i can blame everythig on a lose screw? Also, any tips to remove liquid metal from copper? It got stuck really hard on heatsink surface, i cleaned silicone already.

Sry for typos, i'm really bad at typing on smartphone.

 

Most likely the loose screw. This is equals poor fit on the die. Try something similar like this http://www.frozencpu.com/products/1..._-_30mL_XC-01.html?tl=g8c123s1486&id=uzrm5A76 But you will get a discolored heatsink anyway. Remove what you can accomplish, then apply new metal. And dont forget tighten ALL the screws

 

I don't get it, i used torque tool to tighten those screws and both base and screw is in good condition. And yet somehow i got screwed over, pun intended.

 

You don't need torque tool to tighten those screws. Use common sense and all will be good

 

That's true, but I just happen to have one, because I work a lot with small mechanics.

 

If you're more hung up on getting the right torque, you might forget to tighten all the screws

 

Phuk, found the reason, crappy plastic washer broke and fell off other four are also really fragile, this **** really blindsided me. Why would they put such crap in 1200€ laptop?

 

Everything works fine now, thanks for tips and moral support!

 

Plastic washer on what? What did you do to resolve, did you remove the other washers or replace them all with something else?

 

Plastic washers on heatsink like those

Usually they are durable, or so I think, I only opened like five different laptops, this was only one with this problem. I replaced them with metal washers.

 

Oh noes

 

You can use this, apply a bit of pressure and scrub off the layer.

With your laptop's heatsink being that small I wouldn't doubt that you'll still get overheat on some situation though.

 

Okay I am back.

I repasted with Conductonaut, changed pads, installed 3 more fans on the U3, had issues with laptop not even booting, GPU problems, fixed it all, and dear god am I making a thread about this.

@iunlock I will try to keep the same thread construction as yours has, but dear lord did I do a lot of things wrong. Won't be surprised if my GPU decided to join the afterlife at a random point sometime in the future.

Will try to make it today, literally spent 2 hours on the laptop yesterday, and another 2 today.

 

Good stuff...and I know that feeling. I go 10-12 hours straight with a unit. It just depends how messed up it is.

 

Same here, I've probably invested 12-15 hours on my unit now getting the paste and seating of the heatsink correct! Opened it up and stripped it down 3 times now...

Well with the combined time, I spent 8 hours - tops.

Otherwise I am fast about these things, maybe I should be more careful tho..

 

And as promised, (poor iunlock here I am spamming his threads) I made the thread about my repaste http://forum.notebookreview.com/thr...-to-liquid-metal-msi-ms-1762-tray-mod.801300/

 

Good stuff and good job!

More content and resources is always good.

 

Hey Iunlock, just seeing if you offered repasting for people for a fee?

 

Sexual favors if your a women! lol. Joke. Yes a small fee is required.

 

to be honest I heard it was men

Finally, people are catching up!

 

Hey guys! Just wanted to revive this thread.

I'll have a new XPS 15 here in a few weeks. Wondering if anyone has taken steps to protect the liquid metal from dripping out of the CPU/GPU area from pumpout? I know the exact amount to use from previous desktop experiences with CLU....however, I wanted to see if anyone took additional steps above and beyond the normal protection of components on the substraits...

 

Did that include using the super 33+ tape? That's mandatory! Also CLU is thicker than most LM I've heard so you should be fine!

According to most people that have used both Grizzly and CLLP/CLU, the later two are thicker and the chances of pumpout if you haven't secured the heatsink fully are lower. Still doesn't hurt to fully tighten the heatsink down and use some electric tape on the die

 

Use CLLU, don't skimp and buy the CLLP.

 

Unfortunately the best i can get without importing is CLLP or Kryonaut for regular paste. And given how bad the currency situatuon in my country is, buying from amazon doesnt sound like a good idea now

My question is: is it safe to use liquid metal on a laptop that will sometimes be transported/shipped in Winter?
So the laptop might go down to 0-5 C. I have read that LM is for 10C+ operation only. But what about storage?
Could it become solid and splitter off the CPU potentially causing short circuits on the laptop mainboard later?

 

if the temperatures some time are 0 and 5°C is better to use Thermal Grizzly kryonaut, you have a lot of reasons to note use liquid metal

edit: a friend use to travel with his msi and i repasted his laptop with conductonaut too, everything run very well until he let his bag fall, and the laptop receive a big hit on a corner. when we disassembly the laptop, i could see little pieces of metal like 1/16 part of a dot on the motherboard. we have to clean the little dots and re-apply the thermal paste

 

Hmm. That is not good. He got lucky it didn't fry the MOBO.

 

he didn't use the laptop because we suspect something with the paste could happen

 

They alone will make me steer clear of it. I have a tube of it and was going to repaste it with it but I will leave my Grizzly Kryonaut paste I did last month alone. Not worth it for me as I am always carrying my laptop around. Thanks for the info

 

you can send te tube to me XD hahahah

 

Even with a sudden drop the heatsink would need to be pretty dam lose to allow for this. Do we have any estimate of the viscosity of liquid metal? We could perhaps create a mathematical model to estimate the amount of force required to get it to leak out due to a fall with various mounting pressures.

Honestly I would love to see someone compress 2 pieces of metal maybe in a vice or something with liquid metal in between. The vice could compress the plates to various psi levels for testing. Then drop and shake ect the thing around and see if you can get anything to leek out. I think an experiment like this could put to rest a lot of fear that people have about liquid metal and provide a lot more actual data of how the materials behave under various stresses. Hell you could even take an old cpu and heatsink to make it more realistic.

Hopefully someone with some liquid metal lying around will like this idea and try it out and post some results.

 

It probably came from sides, not between die and heatsink.

 

FYI. Grizzly Conductonaut is wetter in consistency than Liquid Ultra. Hence a bigger chance for leakage. Several have actually experienced leakage with use of Grizzly Conductonaut.

But now it looks like Coolaboratory has changed a bit on the composition of the Liquid Ultra or maybe a bad batch. Aka Liquid Ultra is more like Grizzly now. Not a good move as Liquid Ultra was a better choice. The difference in temp between those metal wasn't big.

 

only 1°C better conductonaut, i tested it on my model using both metals
also you are right, Liquid ultra tend to stay more in place than conductonaut, but i feel like conductonaut have a better life span because it never become solid at all

 

some people complaint about liquid ultra dry with time, i can't ensure that :S i have only tested conductonaut for long time

 

I have still same old application of Liquid Ultra from early February 2014 (AW17 - 4930mx). No degradation and still nice temp. All depends on how good the HS fits on die.

 

You could put a sample in a glass and see how long before it loses its properties exposed to air at room temperature.

I remember years ago the first gen metal TP stuff was actually a solid thing that would heat up and fuse to your die or something crazy. What ever happened to those.

 

This is an excellent post. Thank you @iunlock for putting in the time to explain everything.
I am going to be re-pasting my Sager 8672/Clevo P670SG (i7-4720HQ and GTX980M) with Conductonaut. Will post results soon after. Currently, my CPU temps are reaching 96degC under load. This is with IC Diamond (applied by xoticpc, 2.5 years ago during the initial purchase). Have you seen any degradation of Conductonaut on your build? Any idea what happens with Conductonaut, if it's sitting at low temperature (Below 10 degC). Read somewhere, that below 8 degC, Gallium solidifies and expands. I don't expect the laptop to be in freezing conditions, but it would be good to know.
Any other additional tips/recommendations (other than in this thread). Will be using 1mm Gellid Extreme thermal pads too (12 W/mK, $6 for 80x40mm sheet).
What do you think of using clear nail paint on exposed metal on the die's. Should be as effective as 3M Super 33+. To be safe, thinking of using the tape in conjunction with nail paint.

Thanks...!!!!

 

hahahah dammmm sounds dangerous, like the indium that intel use on his Xtreme processors or ryzen on his new X chips too

also they add something like silicon on the metal parts :O i wish all cpus come with that and so, we could apply liquid metal without any fear

 

@Papusan i would like to see a ryzen cpu on the tornado F5

 

Does the conductonaut corode the copper heat sink?

 

Copper no effect at all. Though it'll stain it a bit.
Only aluminum heatsinks are a problem as far as i know.

No, but will Kill Aluminium in short time...

Info for all of those of you who complain that ICD scratching die, and that you should avoid this nice thermal paste. Die withstand more than you think View from 4.10
