Coollaboratory liquid ultra safe for GTX 980M for clevos?

I have :

Clevo P375SM
i7 4900MQ
GTX 980M SLI

Im using MX4, already re-pasted and "re-thermalpaded" (HAHA dont know how to write this correctly) everything following all kinds of tutorials online with the right thermal pads and milimeters and everything with super caution super slow!! But I'm still getting bad temps, specially on GTA 5 REDUX MAXOUT, the results are:

GTX 980M GPU1 (Full load on GTA 5 REDUX) MAX TEMP : 77° (BAD but acceptable)
GTX 980M GPU2 (Full load on GTA 5 REDUX) MAX TEMP : 88° Terrible, it starts to throttle because of this
CPU i7 4900MQ (Full load on GTA 5 REDUX) MAX TEMP : 94° Terrible!

Not only on gta 5 redux im getting poor results, im also getting bad results on some other demading games as well.

Note: I'm using the latest bios from eurocom which is the one prema made for eurocom (this P375SM is actually an EUROCOM X7E), and I'm also playing with fn+1 full power on the fans activated, and still getting bad temps, everything runing on stock clock, no overclock at all, the only thing i didnt check yet is the vbios from the cards, I bought the cards from Mr woodzstack from ebay canada, i dont know if he puts some kind of performance vbios on the cards before shipping them, I'm using the lastest driver from nvidia.

My question is, can I apply Coollaboratory liquid ultra on the gtx 980m also on the cpu i7 4900mq? I saw it online that it's only unsafe to do it if the heatsink is made of aluminium, I have no Idea if the p375sm heatsink contact part is made of aluminium or copper, although i presume it's copper, I'm just not sure! And I'm also scared that it may damage the gpu or the processor since I'm not sure of what component It's made (obviouslly Coollaboratory wouldn't release a product that damages GPU or CPU, but since I'm a noob, who knows!! So that's why i need some feedback here!! That will give me some extra guts to try this liquid metal thermal compound!). And I saw people relating Drops of 10c° after applying Coollaboratory liquid ultra on some other stuff, like desktops parts and processors (couldnt find anything related to laptops, specially GTX 980M), pretty sure that if some youtuber decides to make an video of Coollaboratory being applied on the GTX 980M (mobile cards in general) and in a mobile processor he would suceed and get lots of attention, simply because there isnt any video of it at this present time.

Have anyone done this or anyother procedure to reduce the temperature for clevos in particular?

I notice that it's a real problem with P370 to P377 GPU 2 to overheat on some other forums, but couldnt find anyone realating the solution, I already bought a new heatsink from germany (apparently there's two models of heatsink for these models for the GPU2 and CPU), apearently I have the bad one that overheats, but since im from brazil its going to take 3 months for the new heatsink to get here.

Any thoughts or solutions? I'd really appreciate if someone can give some ideas! Thanks!

 

77 is great, and 88 is within reason (and not at the point where you should be seeing any throttling - to quote Bane: "That comes later.")

94 is steep, though, and right around the point where you might see some throttling. You can apply any compound you want, really, but be very cautious with the electrically conductive compounds (e.g. Coollaboratory).

Have you looked at the spread of your current paste? Maybe there's insufficient coverage on the die, or not enough contact with the heatsink.

 

Unfortunately GPU2 is throttling, I'm checking the clocks and frequency throttling with afterburn monitoring, GPU2 handles fine until it gets 88°, then it starts to reduce the clock to hold on 88°, then after playing 30 minutes, the GPU 2 clock goes down to 135 MHZ to hold the temperature!!! At this point GPU1 is at 50°, GPU 2 forces GPU1 to reduce its clock as well, Fps goes to 10, terrible! Since I'm scared of damaging GPU2, I turned off SLI and getting better performance after 30 minutes of gaming with just the GPU1 ON, after some research, I concluded that the heatsink that I have here is GARBAGE, this heatsink belongs to P370SM (it's written on it), it's pure garbage, there's not enough copper to handle the GTX 980M, the copper on it is not conected to itself, it's all loose,, the P377 heatsink has a lot more copper and aluminium on its sides, since I couldnt find anyone relating tests with liquid compound for the GTX 980M and for the 4900MQ I'm going to try it myself to see what happens, I already double checked, this clevo heatsink and the GPU/CPU die that I have, and they are not made of aluminium, so I'm fine as long as I don't drop anything on eletrical parts I won't damage anything, I'm willing to try Coollaboratory because it's by far the best results that I found on benchmarks online, I found some other brands as well that people said it's better than Coollaboratory, such as GELid Extreme, Grizzly Kyronaut and IC Diamond 7 (i saw this on a topic here by iunlock), but I can't find these compounds here in Brazil, Coollaboratory is the only one considered high performance that I can find here, and Mr Woodzstack said to me that the MX4 that I'm using is garbage, so... I have to try something or sell my second GPU!!

About the "pasting", I'lready quadruple checked, I Tried the X, the line, the DOT, all same results!!!

So my conclusion is : P370SM GPU 2 HEATSINK = GARBAGE, CPU heatsink is not the greatest either, about the cpu I think I can reduce to 90° with Coollaboratory, I only get 94 °temps on the CPU with full Load, on GTA 5 REDUX all max out, everything else like DOOM I get 70° for the cpu as MAX TEMPS, GTA 5 Redux is by far the most heavy thing I could find until now to test the temperatures, as for the GPU 2 it gets bad temps in any game I try.

 

So does the 7xxM series.

The only overheating I'm seeing per your post is the CPU, and if that throttles, you might see it bottleneck your 980M consequently (x1 or in SLI). You have several variables to consider, I just don't think your GPUs are suffering thermal throttling from the temps you've reported here.

Coollaboratory should get you better temps than Gelid GC Extreme and IC Diamond. Thermal Grizzly Kryonaut will be comparable to Coollaboratory, if not better.

 

Interesting, well, that's the thing, with SLI turned off I can play for hours, the fans doesnt even bother me that much with loud noise, even if the cpu gets a little high temp, it doesnt reduce the GPU1 clock, it stays at 1126 MHz without throttling at all, and about the CPU, like I said, I'm only getting 94° on GTA5 Redux, everything else stays normal, for Dying Light for instance, the CPU doesnt cross 71° and GPU 1 alone (SLI OFF) doesnt cross 78°, and for DOOM i left it for 2 hours game runing all on max, the cpu was stable on 69-70 ° and GPU 70-71° and it stayed runing at 1126 MHz the intire time, it didnt reduce not even once! It was interesting to know that Dying Light i reched 78° and DOOM only 70°. When I play these two games with SLI ON, GPU 2 reaches 88° and it starts to throttle, clock starts to go down pretty fast, not only that, it throttles GPU1 with it, performance gets worse than SLI OFF. For now I'm runing everthing on Artic MX4, if i go with Coollaboratory, which would be better for my scenario? Coollaboratory ULTRA or Coollaboratory PRO?, As soon as I get the the liquid compound and I install it, I'll post the results here with pictures (before/after)

 

GTA V is said to have some issues on the PC port. 94 Celsius is right at that point where the clocks start to dial back, and the 4900MQ tends to run a little hot as it is.

Ultra is top tier. If you're going to spend the money, not to mention the time/effort in applying it, go with the Ultra.

Great! If you're interested, a user recently posted a thermal compound roundup: http://forum.notebookreview.com/thr...e-recommendations-update-thermal-pads.796820/

 

OK!!

Thanks for the tips! As soon as I get my hands on the Coollaboratory ULTRA I'll put the results here, also when my new heat sink arrives from germany I'll also put the results for the gpu 2 temps

Thanks again!

 

Gpu 2 should be the cooler of the two so either the re-pad is not quite right or the heatsink has an issue.

 

It may be worth looking into getting undervolted vBIOSes. Undervolting can make a huge difference for temperatures.

 

Here is what I posted in the Sky X9 review (page 5 here: https://biosmods.wordpress.com/2015/10/21/sky-x9/) showing IC Diamond versus CLU versus delid w/ CLU.

 

Nice results!

What about the GPU? Did you apply CLU on the GPU as well?

I notice on the forums that ppl are only using CLU on the CPU, is there a reason for that? I also notice that Eurocom released some models with CLU applied, but only on the cpu... is CLU bad for mobile GPU?? After googling this alot i barelly found people using CLU on the GPU (and only found one or two examples on desktops GPU), I don't understand why use IC Diamond on the GPU if the results are clearly better with CLU...

 

The main reason for this is the inconsistencies found in the Clevo GPU heatsink. It seems the surface of GPU heatsink is not a truly flat plane. CLU works best when only a thin amount is used. However due to these larger based gaps ICD works better (as it is a bit thicker) in filling is the gaps leading to better cooling for these heatsinks.

Now, if you wanted to lap the GPU heatsink to make a better plane, then there's no reason one couldn't go with CLU everywhere.

 

Lap the GPU ?

 

Primarily because heavily overclocked CPUs are more difficult to cool than GPUs. I have used CLU on GPUs before. It works fine, but CLU is more expensive and it was never necessary to achieve the results I desired. You have to be extra careful because of the surface-mounted components around the perimeter of the die. If you cover them with electrical tape, silicon sealant, varnish or a plastic shroud it eliminates the risk of using it on GPUs. The other thing about using it on GPUs is there are numerous other components that get super hot on GPUs and using CLU on the die doesn't help keep those components from getting too hot. If you're going to do any extreme GPU overclocking, you'll need to use AC cooling to keep the entire GPU cool to avoid slow-cooking the GPU to death. When you're cooling with AC, the CLU is not necessary. Any kind of serious overclocked GPU benching I do with AC cooling. The rest of the time I run my GPUs stock. I overclock my CPUs 24/7. I literally never run my CPUs at stock clocks.

 

Hah! Missed an important word. Lap the GPU heatsink, of course. Thx for pointing it out. Updated my last post.

 

Based on my own experience, CLU is vastly superior in every measure, including the fact that it just about lasts forever. Other pastes do not. CLU only dries out if it gets exposed to air when the heat sink fit is poor. Other pastes either dry out or pump out, whichever comes first, and seldom last me more than a few months of heavy overclocking. In other words, there is no reason not to use CLU.

 

@Mr. Fox, do you feel the quality of these GPU heatsinks match up to prior components? Seems like @Papusan and others were having a hard time due to the plane quality. (Hope I'm not misremembering)

 

Both no and yes. No because of inconsistent quality control and careless assembly. Clevo heat sinks are made well, but sometimes do not fit well. The inconsistent fit is their Achilles heel. When they fit right they do a very nice job. When they do not fit well, they are ineffective.

The exception is the smaller laptops, which seems to apply to all brands. In the quest to make some smaller, thinner and lighter laptops, the heat sinks are often too small to do a wonderful job even if the fit is perfect. They would all build better products if they just ignored the silly kids that are OCD about thin and light and made them all thicker and heavier to accommodate larger, heavier heat sinks with thicker plates, more pipes and larger radiators. Form factor is the Achilles heel of thinner and lighter laptops. The quest for thinner and lighter is the enemy of stronger and more powerful.

 

Thx. So it's the fit, and / or sloppiness of the mounting. Gotcha.

I was picturing some bumpy or warped sinks. Maybe with the P870DM3 vapor chamber - because there is so much surface area, there is more of a chance of this, and I was projecting that to the sinks as a whole - which is incorrect.

Thx, again!

 

Exactly! After researching alot, I found out that there's two heatsink models for the 2nd GPU for Clevos P370 to P377, I got unlucky, I have the bad one, here's a picture that shows the difference betwen the good one and the bad one (the one that I have is the one on the left):


(credits for the guy who took the picture, I got this picture in a forum couldn't find the author post anymore to give him propper credits, sry...;/)

I have the one on the left, it's all loose (not conected to itself), and it clearly has less copper and aluminium, this bad model is more rare than the good one on the right, here's an youtube video of a guy ( GenTechPC) using the bad heatsink with two GTX 680M (apperently this falty bad engineered heatsink it's bad not only for the GTX 980M, but for all GPUs) :



Put on : 8:00 and pause, you'll see that the guy's ( GenTechPC) 2nd gtx 680 is at 93°! And the 1st GPU is at 73°. Put on 10:34 and pause to see that he's using the bad version of the heatsink. Even tough the guy is saying that the temperature is fine, I desagree, it's terrible!

In this video by Igor Barin, you can see how this sistem (P370 to P377) is supposed to be runing:



I don't know if he's using a cooling mod or a cooling pad or CLU, etc... but we can clearly see in his video that the 2nd GPU temp is lower than the first one, which leads me to presume that he has the good version of the heat sink.

The main reason why I'll be appling CLU is to keep my P375 cool on stock clocks, I don't plan to overclock, it's runing hot as it is (STOCK), I'm using MX4 right now and I'm not getting good results, I'm now sure it's because of the bad engineered heatsink, but I already ordered a tube of CLU, I'll be testing it and posting the results here, and as I said previously I already ordered a new good heatsink from germany, I'll be posting the results of it as well as soon as it gets here!

Thank you all for the comments!!

 

CLU may not help, or may even be worse with the bad heat sink. Save the CLU for the new heat sink. ICD is the only thing that might help the bad heat sink while you are waiting for the replacement. CLU is only effective in cases where the heat sink fits properly.

 

Thanks again! I'll do that! But I'll already apply on the cpu to see if gets better, the CPU is only getting bad temps on GTA 5 redux, on any onther app or game it doesnt cross 78°

 

Nabbing hookers and outrunning the popo is very CPU intensive.

 

Pretty much!!!! Not just CPU but GPU2 as well hahaha

 

My new heat sink finally arrived from Germany (I bought it from CEG), and....... IT'S AWESOME!

No more overheating on GPU 2, reduced to 70°C FULL load using MX4, Coollaboratory liquid ultra that I ordered should be arriving until this friday, I'll test it first on the CPU, and see the results, then GPU1...then GPU 2...but yeah... It's comproved, that BAD heatsink is terrible!

If someone is having the same issues with overheating on GPU2 for clevos P370 to P377 you probably have the heatsink on the left:



If you do have the heatsink on the left you're probably getting 83-88° on GPU2, I advise to buy the heatsink on the right from CEG, they were awesome to me, they even sent some candy (I was really surprised with that!), I'm really happy with this purchase, thanks CEG!

 

Yup, CEG are the place to go for Clevo parts! And they always give some candy with anything you buy from them

 

Well I guess this is the conclusion!

Liquid Ultra Finaly arrived, and.....AWESOME! Got great results from it.

I safelly applied with tapes around the die (cpu and gpus)

Results are:
(GTA 5 REDUX ALL MAXOUT) after 30minutes

CPU (4900MQ)
MX4 : 94° (max temp)
CEG thermal paste that it came with the heat sink : 84° (max temp, it was also a good improvement over MX4)
Liquid Ultra : 75°!!!!!! (max temp)

GPU1 (GTX 980M)

MX4 : 80° (max temp)
CEG thermal paste that it came with the heat sink : 75° (max temp)
Liquid Ultra : 70° (max temp)

GPU2 (GTX 980M) (NEW HEATSINK)

MX4 : 77° (max temp)
CEG thermal paste that it came with the heat sink : 75° (max temp)
Liquid Ultra : 70° (max temp)

So yeah, liquid ultra is doing fine on my rig, I was scared to apply it because I saw lots of people saying that they damaged theyr stuff. I guess as long as you don't hurry and be extra carefull you're good!

Btw I have no idea which paste is this that CEG sent to me (it came with the new heatsink), it has a code on it : 6-47-P1578-020, it's also pretty good, and as for the MX4, after all the results... All I have to say is : GARBAGE (at least for my rig).
