Alienware 15 liquid ultra + Artic thermal pads

TEMPERATURE WHILE PLAYING GTA V

 

Good job, I really want to do this to mine but I've only had it for about a week now and would hate to mess something up.

What app do you use to monitor cpu temp?

 

MSI AFTERBURNER


please, DON'T FORGET to use electric tape if you want to use LIQUID ULTRA!!!! DON'T FORGET or you will cause a shortcircuit

 

Is there a reason why you spread the thermal paste over the cpu/gpu die and the heatsink? It seems to be too much paste.

 

no, the pressure from sandwiching the CPU/GPU to the heatsink should spread it out and fill the gaps in both surfaces.

 

in this case is absolutely necessary ... is liquid ultra ( liquid metal). It has to be PAINTED, also come with 2 brushes to do this task

 

in this case you are wrong ( this is a video posted by the brand )

 

I see, thank you for clarifying.

 

Looks great! Out of curiosity, you did take off the electrical tape after applying the Cool Labs Liquid Pro/Ultra, before putting the heatsink unit back on? If you kept the electrical tape on there, wouldn't that create too much insulation for the massive amount of heat that is generated in that area anyway?

Thanks.

 

I now use masking tape if I can't physically remove the C/GPU and heatsink from the system to apply CLU/P. I repasted my first 4 systems without masking off the surrounding area but the last few were systems I repasted were very expensive so I used tape. The tape only stayed on while applying the paste and was removed once finished.

Of the seven systems that I've applied CLU/P to, there hasn't yet been any movement of the liquid metal once it is correctly applied so I'm doubtful as to whether you need to leave the tape on afterwards. I applied CLU to a friend's system and they subsequently read speculation online that the CLU would run off the CPU and short out the components so they took clear nail varnish and painted over the surrounding components. I'm almost certain that this was a terrible idea but the system is working a year and a half later and the temps are the same - although for how much longer is perhaps the crucial question.

 

you need to keep the electrical tape, and no, the metal rectangle is the unique area that transfer heat. That is why you only apply thermal paste there and don't apply in the totally

 

i dont want to cause a short circuit, that is why i keep the electrical tape, and i followed the instructions of MR Fox, known as an enthusiastic overlocker. I saw his examples and after a year using the paste like me, the electrical tape was intact. Also my temperature is a good signal of a good application.

 

That's fair enough. My experience with applying it to 7 systems over almost 2 years is that the 'paste' won't move at all but it's better to be safe than sorry.

Just to ask, why *wouldn't* the electrical tape be intact after a year? What would cause it to not be intact?

 

i dont want to run the risk. thats all

 

You read the last bit I wrote, right? I just asked what would cause the electrical tape would not to be intact? It's in a sealed case - it's hardly going to get abraded.

 

Mmm....thanks but I know what the IHS area is. My question was whether he kept the electrical tape on over the little transistors. - It's been answered in that it was on there only for when applying the CLLP/U and removed afterward. ie...It was just used as painters tape.

Great to know....thanks for the confirmation. I am a bit surprised though considering that the tape would add a significant amount of insulation over the transitors.....

Same here....after numerous CLLP/U applications over many cpu's, it's never run off the IHS....

I'm thinking for those who've experienced that, they've applied too much.

Great thread! This is EXACTLY what I've been looking for! I'm picking up a new Dell XPS 15 9550 in a few months and I have some CLU on the way. I've read there's some heatsink contact issues with the GPU but that can be easily fixed. I'm crazy about temps so I'm going to use CLU on the CPU and GPU. My main concern was the CLU running off the heatsink and dropping onto the motherboard but this has set me at ease. I'm very involved with cooling and understand exactly how to apply this stuff. I'll be testing it out on my 2500k before I get my laptop. I'll also use some liquid nail polish to cover the caps on the GPU and leads on the CPU. Many people on OCN use LNP for their delided CPUs with no adverse results.

I'll be sure to upload lots of pictures!

 

My concern would be the heat. Heat is known to melt electrical tape. It is also known to make it gooey and over time, it will cause it to become very brittle. Personally, I would never use electrical tape on the processor like that, but to each his own.

 

this electrical tape is for high temps

 

People I know over at Overclock.net use liquid nail polish as I said earlier. I'll be using it on my xps 15 when I get it... I've got some CLU coming next week.


Both CPU's have nail polish over the transistors to prevent shorting.

I've read that nail polish melts around 120C so its pretty safe temperature wise...

 

Wait, so you douse the transistors around the die with nail polish and leave it there? Or do you clean it up once you're done applying the paste?

 

I'm fairly sure he means to leave it there, I have a couple of friends that have done the same.

 

Huh, is nail polish fairly thick? I always thought it was watery and would just flow off if you tilt the surface. Also, what do people recommend to use to clean off stock paste that is stuck between the gaps in the transistors?

 

ArctiClean. ..it's two bottles, #1 and #2.

Great stuff.

Kinda, it thickens pretty quickly, though it depends on the brand according to my girlfriend!

 

I've got an endless supply at home...well it sure seems that way...

 

Uh, if I used pink nail polish the coloring won't damage anything right? Maybe change all the lights to pink so my laptop feels better.

 

i am not going to trust the life of my notebook on a cosmetic item .... i am a mechanical engineer and i prefer industrial stuff. like this tape that resist 130°C

Electrical tape sounds more appropriate for the task, but I just feel like it'll insulate the heat.

 

you saw my temperatures ? looks like insulation ?

 

Ah guess not. If you don't mind, could you run realbench (from asus) and do a stress test for 10 minutes and monitor with something like hwmonitor so I can see the max peak temps? Kind of hard to tell with afterburner. Just want to compare it to my temps after applying gelid paste.

Also, for the tape, it looks like you just tape it RIGHT up to the edge of the die? And you surround both dies?

 

I put tape on everything with metal color ... around the cpu and gpu chip. I thought that the pictures were enough specific
i am going to do the test ...

 

The pictures are pretty specific, but just needed that redundant confirmation before I attempt. Looking forward to comparing temps! Include both CPU and graphics if you can. Thanks!

 

15 minutes stress
test


i have an undervolt and a mod multiplier ... because i found that the max freecuency that the cpu can reach without power limit throttling is 2.9GHz in four clocks. i forget to take the gpu temps ... i have a Overlock in my gpu +150 core +400 mem... i am going to repeat the test, but this time with stock gpu and stock multiplier cpu. right ?

 

I have my cpu set at 40 multiplier in bios. You can keep your gpu at your o/c settings since voltage is the same. My cpu has 0 offset for voltage. I have the 6820hk cpu which I think you don't have since your die looks longer than mine when I took my a17 r3 apart. Which cpu is yours? I'll attach my after temps with gelid paste applied. This is after 15 minutes of stress test, multiplier of 40, no voltage offset for cpu, gpu is +135 (can't go higher with afterburner) and +200 memory, no voltage offset.

 

i have a i7 4710hq ... weaker cpu and hotter ( you can go higher using Vbios mod from premamod.com like me) and wtf say dell xps ?

 

now everything in stock mode

 

Well you convinced me to switch over to liquid ultra. Your hotter cpu and your gpu both run cooler than mine. Maybe I put too much paste, I dunno, but good stuff! Real bench is unrealistic as the system is never pushed that hard in real world scenarios, so that's some mighty fine temps.

 

i made the test again with my own cpu multiplier ( to prevent power limit throttling) and my undervolt, with the gpu oc ( this is a lie XD **** i forgot to apply the OC XD lol )

 

Is it required to paste the heatsink in addition to the cpu/gpu die? On the heatsink it's almost like a blind paste as you don't know exactly where the heatsink will connect with the die. Also if you double paste on heatsink and die, wouldn't that end up being too much paste?

 

No need to put any paste on the copper heat sink. I've looked into this a ton when I was repasting my gaming desktop rig and from what I've seen it makes no difference at all.

There is the theory of putting a little on the heat sink to fill in any micro grooves etc...however, the paste will fill those in regardless so it's not necessary to "tan" the heat sink...ie. ..lightly brush thermal paste on the heat sink. ...no need.

Just make sure the heat sink is very clean and you'll be good to go.

Ah, I'm just concerned that since every video I've seen, people are spreading the paste extremely thin and am worried it's TOO thin and won't make contact with the heatsink.

With that said, how did you clean the brush after use? Would the spatula spreader that came with the gelid kit work? Or does it have to be something rough like a brush or cotton swab?

 

Upon all the real world tests I've seen and have performed myself, using a little more (slightly) is preferred than using too little. It's important to keep in mind that the thermal pastes purpose is to fill in the gaps and to provide efficient heat transfer. Therefore, I've always wondered, would too much of it become an insulator at some point?

According to all the tests, the extreme ones done on purpose where people would glob a ton of paste on the cpu etc....it made no difference. - this is not to say that overloading the paste is a good thing.... however. ...

It boils down to being application specific. Since our 14nm skylakes die has a much smaller surface area, we wouldn't use a traditional pea size amount like we would with the 4th Gen cpus. As a rule of thumb, I've just divided the amount according to the size decrease. So about half? Around there....mmm. maybe less...even half is too much. Just start with a size a little more than a rice grain and go from there.

Now the whole dot vs spread method etc. ....this is completely subjective. I can only share how I do it....

For bigger dies I use the pea size dot method.

For my skylake AW, I've used the spread method. Make sure to only use one side of the applicator and in one direction from inside out.

TIP: While making sure all the surface area of the die is covered, I've found it best to leave the center area a little thicker so when the hest sink sits on it, it'll also spread outward to give you the peace of mind that there's enough...also make sure the layer is even as possible everywhere else, except the center area where you can leave it slightly thicker.

Just to throw my experience in.

I just got my syringe of CLU yesterday and applied it to my i5-2500k desktop CPU. The whole point of "painting" the CLU on both sides of the heatsink and die is to ensure there's proper "wetting" of the two surfaces. Gallium/Indium/Bismuth/Tin liquid metal does a very good job of "wetting" metal surfaces, which means they stick to the surface rather than bead like a drop of water. If you take your time to paint on the CLU or CLP and properly wet the surface with the TIM, you shouldn't have any problem using too little...only if you use like the entire tube then you'd use too much. I used just barely enough that would cover the entire heatsink area that makes contact with the CPU and the CPU its self.


Take a look at my CPU. Instead of using the brush that the CLU comes with, I just used the tip of the syringe and just swirled the paste till it covered the entire area. That way I'm not wasting paste that gets stuck on the stupid brush it comes with. Some people might use the brush but I found it better to just use the syringe head and not waste any of the super expensive CLU.

Conversely, I also applied CLU to the surface of the heatsink. I wanted to properly wet both surfaces so when they join, there's no gaps.


Before in the same benchmark with using PK-2 thermal paste I'd get 66-67C across all 4 cores, now I won't even reach 60C. Pretty stunning results I believe.


Overall I used about 0.5g of the 1.5g tube on my desktop CPU. I'd imagine you'd use that much for both the CPU and GPU of a skylake laptop and mid size graphics die from Nvidia.

Overall I'm BLOWN AWAY by the difference when using CLU. I've NEVER had temperatures this low with my overclocked 2500k. There's no doubt now I'll 100% use CLU on my XPS 15 once I get it. I believe this is a "must have" for laptops... With a low pressure heatsink on the CPU and GPU and contact issues in a laptop, IMHO CLU is designed for laptops...

 

Nice pics! Never thought of spreading the paste with the syringe itself. Was wondering how to clean the brush after. I would not use a cotton swab like some of the official videos show. Way too much risk of cotton pieces coming off. So your temps dropped even further from a previous paste job. Imagine how much diff it would've been from factory!

 

Yea, I'd just use the tip of the syringe. It was the easiest for me and you'll have very little, next to no waste.

I'd use it on my old dell xps 14 but I'm selling that here very soon so its kind of a waste. I can't wait to see the before/after on my Dell XPS 15 9550 once I get it. I'm sure its going to be night and day difference, not only that but it'll probably cut the fan speed in half.

 

Everyone using electrical tape as well yes?

I'm not too fond of clear nail polish...

Also have been looking into some high grade electrical tape that can withstand 130C+ ...not that it needs that ceiling, but it's always good to have the assurance.

So far from what I've seen, taping over seems to have zero impact on any heat issues due to insulation.

Additional thoughts?
