Repasting with CooLaboratory Liquid Ultra, any tips before I start?

Good cooling and a good sample can do wonders

 

I'm gonna do the electrical tape as well. Thanks for showing that, I was actually thinking about it this morning and I'd rather be safe than sorry, especially since the heatsink assembly allows the actual contact surface to move when you're putting it back in the machine.

 

Yeah it slides just a bit but it's fine. I've repasted twice and never put any electrical tape on the CPU.

 

I never had electrical tape on it before. As long as the CLU stays put there is really no need for it. I did it mainly to see what it looks like in 6 to 12 months (depending on how long the CLU lasts before it needs repaste). I think it will be interesting to look at if nothing else... just for giggles mostly, to see if it stays in place or gets all gooey, or what. I also did it as a demonstration for those that are really paranoid about using CLU.

 

I hope it lasts longer than 6 months, its not cheap and its not easy to find. I hope my tube at least arrives intact.

I have no doubt it will. I was over 5 months with no signs of degradation (see previous photos posted). At the rate it was going, I would not be surprised if it went a year or longer.

 

I'm honestly wondering if reports of it failing weren't the old Pro stuff.

Well eventually at some point it will degrade, but that's probably after a year of hard use.

And just be aware the drop may not be as dramatic as you'd like especially if contact pressure is insufficient. I got lucky in that my CPU heatsink is most flat:


So I saw about a 7C drop in temps under load. This is important because Liquid Ultra is supposed to be spread thin on the die, so if there's not enough pressure the improvement may not be as good.

 

It's hard to say since I haven't tried the old Pro stuff... could be more durable than Pro, or could even be improper application. Depending on what system it was in where failures were encountered, unrelated things like chassis flex can result in the heat sink(s) moving and shifting around, and this will also affect thermal paste longevity.

 

From what I've read MTBF is at least 9 months. Just don't do what this Mac user did.

 

What if the tape melts and becomes stuck onto the card?

 

I was wondering about that... Google says electrical tape melts around 80C

Would this stuff work though? https://www.sparkfun.com/products/10687

258C rating on that one.

 

You're a brave soul Mr. Fox. I chickened out and just pasted with Liquid Ultra. I didn't want to take the chance of the tape melting all over those SMD components. What a disaster that will be to clean up. I wish you the best of luck brother Fox.

 

Not sure it would make any difference even if it does melt. Who knows, maybe it would do an even better job of sealing off things if it does.

A trusted technician at PowerNotebooks told me that is what they use for their in-house testing instead of the shield sold by Clevo and it works fine, so I doubt it will be a problem. I guess we will find out eventually, when I take it apart to have a look.

 

Hmmm I'll hold off until you've confirmed it's ok to use it. Are you using typical everyday electrical tape?

 

i need dis nao

 

for the cpu, clu is enaugh to apply it on the cpu or to apply also a small amount on the die?

 

Did you even bother reading this thread???

 

I read only the 5-6 pages and the last 3-4 pages...I will read them...but an image it will be better then 1000 words

 

A quick search turned up this

 

I noticed you tried the pressure paper on the master 780M. That is pretty much what it looks like with my Clevo as well -- pressure on two sides, but completely lacking in the middle. Seems like nobody can get the GPU heatsinks quite right for some reason.

After lapping my slave heatsink down I did notice a 3-4C drop in temps, so it helps, but isn't absolutely necessary (although I may have gotten lucky with my heatsink). If only I had some pressure paper on hand to see what it looks like now..

 

I found that the thermal pads cause the heat sink to lay funny in the die. But the problem is, we can't go decreasing the pad thickness as you're well aware. Shame we can't get our heat sinks to lay fully flat.

 

I was wondering if the pads were causing an issue... Hmm...

Don't think it's pads, otherwise one side would would have too much pressure while the other side would not have enough, but in this case (and my case) it's t the middle that lacks sufficient pressure.

Seems more like a concaved heatsink to me.

 

Yup, you're right... great contact on the edges and too light in the middle of the die. My GPU temps are fine, so I'm not going to worry about it unless that changes.

 

Yeah and my slave GPU shouldn't be affected by pad sizes at all since the heatsink is separated from the rest of the assembly. Just wishful thinking on my part.

Still enjoying my liquid ultra, temps are beast and are still the same. I even unlocked some new magic power out of my CPU.
I think some people should check my post here with the Ivy bridge QM CPU's

The cpu's are unlocked but still a little bit locked, you can't max out the the TDP further, only change the multiplier but nothing really much changes afterall.
Now I found a way to make them really something faster (bypass max TDP), and the benchmarks will show it!

Hope some people can use it .

Yeah I see you've increase the Reference Clock (BLCK) in XTU. Alot of members have been doing this for some time. Thanks for sharing your findings. On a side note be careful using too much as it overclocks everything in your system, not only the CPU. So if you are getting strange errors you've likely over done it.
And yes! Liquid Ultra is awesome isn't it

 

I applyed also CLU on cpu and gpu the temps droped around 5 degrees at cpu and 4 degrees at gpu...so from 81 to 76 and 81 to 77 compaired to Polimatech pk-3.
I want to see your electrical tape job MR FOX

 

Nice results. Good job! You can see a picture of it in post #446.

 

Cant see the electrical tape, only the sli connector

 

Its this post http://forum.notebookreview.com/ali...a-any-tips-before-i-start-45.html#post9723407

 

AA
The black one around the cpu... I thought you will put something on the heatsink over the cpu
like here
http://forum.notebookreview.com/alienware-17-m17x/747353-mod-heatsink-alienware-r3-r5.html
I wander if I put only thermal pads on the heatsink on the cpu....I dont know if you understand me, so is the cpu + thermal paste +heasink close the screws and then thermal pad...It will make a diffrence?

 

If you're talking about adding copper pieces to the heat pipes, its unlikely to be beneficial unless a fan blows directly on it. The heat still has to go somewhere so if there is a fan blowing on that area, placing some copper heatsinks will help to dissipate heat otherwise it's going to get trapped and make temps worse which is why I removed the extra copper heatsinks from my Sager because I don't have a notebook cooler.

CLU makes a BIG diffrence on my laptop I will only change the cooler master pad vents to 3x 120mm vents and hope to get 2-4 degrees out of it and that's all.

 

Hi everyone I am new here and I own an Alienware 18.

I need help, because I have just ordered the CLU and I have been reading up the forums here to get some tips. About time I ask, is it worth applying the CLU on the 780M SLI? Also, are there any safe tips to prevent accidental spilling of excess thermal compound on the board and heat sink, because the video of Galium weakening Aluminum given by Mr Fox kinda scared me on whether its worth the risk to do it on the GPUs

Thanks
Jasper

 

I applyed on gtx 780m CLU, and the dell service guy apply a LOT....but he spread it and didnt apply also on the heatsink...only on the gpu...I have room temp of 29 and gpu doesnt go over 70 gaming , I am VERRY pleased with CLU. recomend
If until now there is no probleme only low temps...it means that CLU is good?!

 

Wow, CLU Impressed me. Thank you guys, especially Mr. Fox

Room Temperature in my room was 25 Degrees Celsius

Updated my AW 18 Bios to A09.

When I use Hwinfo to blast all the 3 system fans, I ran Heavy Load (CPU Loader) and FurMark GPU. CPU was 100% and FurMark was doing a 1920 X 1080, 8X MSAA Burn In Test.

The temps were..

BEFORE (Stock Thermal Compounds)
CPU Max: 100 (Thermal Shutdown)
GPU 1: 80-83
GPU 2: 80-85

NOW (CooLaboratory Liquid Ultra)
CPU Max: 75 degrees
GPU 1: 60-65
GPU 2: 60-65

WOW!! INSANE TEMPS ON A LAPTOP!!

 

Don't run Furmark if you want to keep your GPUs alive, I don't know how many times it has to be said before people will understand that.

Congrats on the temps, very nice indeed.

I don't remember seeing anyone mentioning this before, unless I missed it.

Have any of you tried this?

Amazon.com: Coollaboratory Liquid MetalPad 3xCPU / 3xGPU + Cleaning kit: Computers & Accessories

I wonder how this works in comparison?

 

Not sure anyone has tried it to see how it compares. I see they have Liquid Copper now as well.

 

It's a silicone paste with nano copper particles. So easier to apply (more like normal paste) but not as good as liquid metal.

 

I wonder how mercury would work. It's got to have all the liquid metal pastes beat for sure lol.

 

Especially in brain damage.

 

Edit . Don't try this . It will Definitely ruin your system .

 

Here is a little comparison. :thumbsup:

I boought a 680m off eBay yesterday and the person I bought it from suggests I use cool laboratory ultra metal over ic diamond. Is it worth the risk using a conductive compound to get cooler temps or should I just buy some ic diamond?

 

I advice not to use Ultra metal on GPU, if you apply little more amount of it on GPU it may damage it. ICD is excellent for GPU.

 

What about CPU?

 

It's depends which CPU you got, for Sandy and Ivy bridge not much risk. But for Haswell you got to be careful as it may damage it cosz there are some metal contacts at below die.
