Apply Thermal Compound to ASUS G50VT

Recommended Posts

I wrote an article on my website and wanted to share here (you can read in spanish)

EDIT: A complete guide to disassembly the Asus G50 can be found here: http://forum.techinferno.com/asus-gaming-notebook-forum/560-official-asus-g50-disassembly-guide.html#post6282

At this time we will see how clean and apply new thermal paste to an ASUS G Series (Republic of Gamers) more specifically the G50VT X1 model, however, this process may be the same that applies to all G50 and G60 series. This laptop began to raise their temps, mainly GPU.

Before making the process of cleaning the fan / heatsink and applying new thermal paste, the temperatures were in:

Normal use:

CPU: Between 30 ° and 40 °

GPU: Between 60 ° and 75 °

Doing a "stress test" with FurMark 1.9 (only 3 minutes)

CPU: Between 50 ° and 60 °

GPU: Between 90 ° and 97 ° reaching 106 °!!

Note: Furmark stress tests performed in order to know the answer to take your 3D graphics card generation and whether it will be able to run the most demanding programs and games.

As you can see, the temp of CPU (both cores) are not unusual, tem are quite acceptable, but the GPU is too FU***** high.

After performing the cleaning process and application of new thermal paste temps are:

Normal use:

CPU: Between 26 ° and 38 °

GPU: Between 41 ° and 58

Doing a "stress test" with FurMark 1.9 per 15 minutes

CPU: Between 40 ° and 47 ° max 57 °

GPU: Between 80 ° and 90 ° with a maximum of 92 °

Playing for a while Hydrophobia Prophecy the GPU max temp was 88°

I started with the cleaning and application of new thermal paste. What we need is a tube / syringe of thermal paste, I used Artic Silver 5, a Phillips screwdriver. Antistatic cleaning cloth, a pair of coffee filters (yes coffe filters!) A lot of patience! so lets started!

You must remove the top / main deck of the machine, so you'll see the following parts that you need to remove:

post-204-14494987990513_thumb.jpg

As you can see in the image, the red circles are the screws that you need to remove in order to release the heatsink and fan. Also be sure to remove "gently" fan connector marked with the blue circle.

post-204-14494987990703_thumb.jpg

After releasing the screws and the fan connector cable, "gently" pull up the CPU headsink, may be a little stuck but do it slowly and gently. Later will do the same with the fan cooler, the fan "box" is attached to the GPU headsink through a "duct tape" so you must be gentle to avoid any damage. Once released the Fan cooler you can put aside while you go to releasing the Headsink of the GPU. In my case, this Headsink was quite stuck, but after a few attempts you finally pull up

once you've removed the headsink you now should start cleaning...the fan box has 3 screws that need to remove to be able to clean easily. Likewise, you should clean the sink grids that are filled with a lot of dust, preventing a good flow of air. This process can be slow, because in order to clean the grates you need something small to get inside and clean the stuck dusting. In my case I used a set of Screwdrivers that can also serve for other tasks.

After cleaning the headsink you should proceed to clean the processor and GPU. Both have thermal paste residue that should be removed. You can find many online methods, but the one I used is quite practical. What you need is isopropyl alcohol, Widely used in cleaning of photographic lenses and electronic contacts, as it leaves no marks and is fast evaporating. It can be 99% pure or 70%. You can use 'Q tips "for this process, wet (very little) the Q tips on alcohol and rub it gently on the surface of the CPU / GPU to completely remove the thermal paste. Must be completely clean, you can use the "technique of the credit card" which as its name suggests you use an old piece of plastic card or similar to clean the remains of thermal paste. DO NOT use anything that could scratch the surface

Once you've completed this process, the CPU / GPU will be like in the picture below (Note that I used a cloth underneath the laptop to prevent scratching)

post-204-14494987990894_thumb.jpg

The next step will be to apply new thermal paste. In my case, as I said before I used Artic Silver 5 with very good results. For more information about this product you can see the official manual here.

There are different methods for applying the thermal paste, you can find videos on youtube like this

I applied the Artic Silver 5 method. Do not apply too much or little thermal. The recommendation is to cover the entire surface of the CPU / GPU evenly to avoid the so-called "air bubbles" Do NOT use your finger to apply the thermal paste, because the human skin contain grease and this will contaminate the electronics surface. For that we will use coffee filters in our finger, and gently apply it the thermal paste.

The purpose is: the thermal paste is a driver which sends the heat from the CPU / GPU to the heatsink and through the fan, this hot air is taken out of the laptop. If exist "air bubbles" well...no good thermal conductivity, so: high temps, that's my explanation, let's see the Wikipedia: The thermal paste, also called thermal silicone, or thermal grease is a substance that increases the conduction of heat between the surfaces of two or more objects that may be irregular and do direct contact. In electronics and computing, is often used to help heat dissipation of components through a heat sink.

A hair, piece of lint, and even dead skin cells can significantly affect the thermal interface's performance

An important point to note is that any thermal paste need a break-in period can be a couple of days or a week depending on computer use. By this, temps will decrease gradually, so if you dont see a big difference in degrees after apply new thermal paste take it easy, you must give some time to adjust.

Remember to monitor temps to confirm that you did a good job. To do this you can use programs such as HWMonitor

Here is my temps on HWMonitor

NOTE: I know, my english sucks...but I try :) ..take care and be safe!

Thanks for sharing man! good job with the temps, what I do to apply the thermal paste is to have a drop at the size and shape of rise and let the pressure of the heatsink and the heat to take care of the rest, no spreading or anything, works best for me so far, after tests I found the proper amount too and I don't see any paste outside the die either.

that kind of methods are also effective...i know that...applied the method of spreading because it is one of the recommendations of AS5 for Core 2 Duo processors

Have you tried any other compounds like shien etsu, OCZ freeze or MX-4 for comparison reasons?

from what i've seen others posted is AS5 is not as good as other paste on the cpu but for gpu its on par with everyone else. i also recommend the line/dot method too, the spreading method works also but have a higher chance of getting air bubbles.

I had an Asus G51 that had a similar layout and I put sinks on the GPU/CPU heatsinks. Also cut a hole in the bottom cover and put a mesh there so the fan could breath and it improved cooling quite a bit.

i have had this laptop for a few years. it's just poorly designed. there is no way to make this laptop run cool when running a game.

i have cleaned the laptop and re-applied thermal compound as well. no real difference except it's cooler when not running games.

if someone wants to cool this laptop and it's past their warranty, i suggest replacing the intake fan and perhaps making custom heatsinks.

the best thing to do with this laptop is to use power4gear hybrid utility that comes with it to crank down the maximum processor state.

or you can do like me and run it with the back off. that reduces temp significantly

Of course, but also attracts more dust!!! ;)

I realize that this thread is old, but I have taken apart and re applied the thermal compound. Heat is a big issue just running and this seems to help, however any thoughts on why my fan/heat sink is so noisy now? I've checked the screws and everything is tight, but its a horrendous noise that really disturbs the rest of the users around. I can slap the computer near the heat sink and the sound stops for a moment, then its back.

Anyone with thoughts?

you need to replace the fan cause it's starting to fail

just the fan or the whole heat sink assembly?

Sweet! Thanks for the help. maybe I can get this machine to be worth turning on again. Appreciate the assist!

Agree...this machine is not noisy like you said...and like @StamatiX said you need to replace ONLY the fan

You need to check if the noise had it before or after you changed the thermal paste. Check that you have not left a misplaced piece

Good luck!

The stock fan in your laptop is most likely a Delta KDB05105HB “7F36”fan. You can replace it with a more powerful fan, which came by default on the Asus G51j and vx laptops. This is the model number of the upgraded fan; Forcecon DFS541305MH0T “F8U5". Google that and you can find it for cheap. The Delta is a 13 fin fan, the Forcecon is a 17 fin fan. Moves more air but fits right into your existing heatsink and plugs into the motherboard for power.

okay i had a similar issue and I was on Google Chrome browser. I tried on another computer and in Chrome and the issue was gone. I tried Internet explorer assuming windows pc... and my issue went away... I have not gone back to chrome for viewing TI on my computer since though so i am not sure if a clean install will fix it am do for a windows clean install anyway.

      Hi all,
       
      I'm debating whether or not to replace the thermal paste in my Lenovo y510p. I've started overclocking a bit, and I have an external fan, but I would like to not have to run the fan as fast because it is a little loud. I have been reading a bit about different thermal pastes, and I'm wondering if there is even a big difference between stock thermal paste, and something like the liquid metal from thermal grizzly. It sounds like it'd work better, but I don't want to fall for a good marketing scheme. If anyone has experience with this and has or hasn't seen big differences, your input would be greatly appreciated.
       
      Thanks in advance!

      Thermal Paste Complete: Mandatory. Not an Option.

      * Don't mind the MX4 LOL that was just left over from something... How about that toothpaste that is rated at 401w/mk...which happens to be the thermal conductivity of copper.
       
      Greetings,
       
      I will be repasting the P775DM3 very soon and will be posting up the results w/ a lot of pictures for your entertainment. My liquid metal paste of choice will be Grizzly Conductonaut, however, I'll be experimenting with other pastes as well to satisfy any curiosity as to if one can get by with just traditional paste. (Highly doubtful, but I am curious about GC.)
       
      Traditional paste wise, I have a feeling that GELid will hold up pretty well.
       
      While I'm at it, I'll also be replacing the thermal pads. Depending on how warped the heat sink is, I have pressure paper handy to be able to test the contacts of the die and IHS against the Heat Sink. If needed, I have copper shims standing by of varies sizes from 0.1mm to 0.3mm+ ...
       
      Below are the conductivity numbers for the top Liquid Metals and Traditional Paste:
      (As we know the numbers don't mean everything, however, from all my tests done so far, Grizzly Conductonaut has always topped CLLU by an average of ~3C. Results may vary and it can be the case where it's the other way around. However, the thing here is that with these beasts, every drop in C's count. It could make all the difference.)
       
      Liquid Metals:
      Thermal Grizzly Conductonaut - 73 W/mk
      Coollaboratory Liquid Ultra - 38.4 W/mk
      Coollaboratory Liquid Pro - 32.6 W/mk
       
      Traditional Paste:
      Gelid GC Extreme: 8.5 W/mk
      Grizzly Kyronaut: 12.5 W/mk
      ICD: 4.5 W/mk
       
      ------------------------------------------------------------------------------------------------------------------
       
      Project 775 Journal:
       
      Straight out of the Box:
      The temps when running OCCT on the CPU reached 99C on all four cores. Even on F1, the CPU temps all maxed out. Yikes right? As for the GPU, when running Unigine Heaven and Fire Strike the Temps were also in the high 80's and 90's. Repasting is a must IMO. 90C's is not okay and there's no justifying that. I know it's such a shame on Clevo's part for poor QC and lack of engineering (as demonstrated by the crap ADDA fans that are used), but it is what it is. If you want something to just work out of the box without any modding, then a DTR is not for you. Simple as that. Yes, it should work within normal operating temps right out of the box, of course, we would all agree. A DTR is for enthusiasts and those who have the willingness to get under the hood. Some of us thrive on this fact, while others don't, but at the same time this doesn't give Clevo an excuse to go cheap on us.
       
      Project Delid + Liquid Metal Magic: (9/22/16)
      The Repaste and Delid are now complete. I've been gathering temp data non stop, along with fine tuning the machine to find where it is the happiest. The temps have been amazing and I'll be posting up a full review shortly. - Stay tuned...
       
      Fine Tuning: (9/25/16)
      It's been a blast fine tuning the beast and I think I've got it to near optimal range. The CPU is a winner in the silicon lottery, thank goodness. I'm holding 4.6GHz @ -200mv Core / -200mv Cache and it's very stable with gaming, running benches, video encoding etc...As for the GPU, it's a working progress. After about 100+ runs...yes really of fine tuning and recording data on a spreadsheet, I think I've found the GPU's sweet spot. It's not a massive overclocker chip, but it's good enough to get a great boost out of it. Then again, my expectations are very high so anything sub par is not good enough. I'll be running more benches tonight and hopefully the tuning will pay off to take the #1 spot int he P775DM3 Class for Fire Strike, Unigine Heaven, Cinebench R15, Time Spy, wPrime (already recorded and sitting at #1 in this class) etc... I'll keep you all posted!
       
      ------------------------------------------------------------------------------------------------------------------
       
       
      Please post your results using the format below in order to keep things uniform and organized:
       
      >>> Before repasting, please run the benches and record your temps for a base. <<<

      I've seen a few people asking about heat and I thought I would chime in and say a few ways to keep down the heat! There are a few ways you go about this without opening the computer, for those who aren't to sure about taking a screwdriver to their laptop it may help you. In saying that, if your fans are dirty then this will not help you at all.
       
      I TAKE NO RESPONSIBILITY TO ANY DAMAGE HARDWARE! ANY CHANGES YOU MAKE ARE AT YOUR OWN RISK!
       
       
      INCREASING THE FAN SPEED
      to control your fans use this
      http://www.hwinfo.com/download64.html
      this is a free program that alot of people use on various computers. it work on alienwares well but im yet to test ROG and MSI with it.
       
       
      its pretty simple to use
      install it and get to this page and click on the sensors button

       
       
      then on the next screen click the small fan icon at the bottom

       
      unless you want to manually adjust your fan between each time you play click customer auto and you can edit it from there
       

       
      UNDERCLOCKING
      download and install NV tools it can manage fan speeds too but its not always 100% in laptops
       
      http://www.nvidia.com/object/nvidia-system-tools-6.08-driver.html
      on the left hand side, under the performance tab, select device settings
       

       
      now just slide it back in small steps until you are comfortable with the temps. remember that if your computer blue screens it DOES NOT mean your computer has been damaged. it is simply a way for the computer to avoid damage.
      adjust the slider in intervals of about 15mhz to be safe and click apply each time. 
      start on the core clock and finish on the memory. Every now and again it is good to check on your progress to see how far you need to go. (more on this later)
       
      MSI after burner is a good one too
      http://www.guru3d.com/files-details/msi-afterburner-beta-download.html
       

       
      again the fan control is a bit hit and miss with it but it can control your clock speed. ass per the program above keep going untill you hit a STABLE setting you want.
       
       
      TESTING
       
      here we will look at the new GPU temps after the tune.
      MSI Kombustor is a great way to test your heat. 
       
      http://www.geeks3d.com/20150710/msi-kombustor-v3-5-2-64-bit-v2-6-0-32-bit-download-gpu-stress-test-benchmark/
       

      click on stability and watch the temps. if you see any artefacts stop the test and increase the mhz by 15mhz each
       
      fur mark is the one that i use to test the heat of my alienware
       
      http://www.ozone3d.net/benchmarks/fur/
       
      aim for about 70-75*C.
       
      hope this helps you a bit.
       
       
       
      PS avoid EVGA's tuning tool on alienware i have heard it can brick your LCD!
       
      CLEANING THE FANS
      Just for the sake of it ill give you a few tips on cleaning your laptops fans out.
       
      assuming you already know the basics of using a screwdriver to open a laptop ill cover a few things to help you.
      REMEMBER, IF YOU REMOVE THE HEATSINK YOU WILL NEED NEW THERMAL PASTE!
       
      compressed air is a great way to remove dust and id recommend having a can of it over a compressor. The reason being is that some compressors can fill with a bit of water and can spray it directly into the computer.
      you can spray the air into the vents and while it wont really "clean" it it may open enough room for air to pass out. i DO NOT recomend this however.
       
      after opening up the computer and removing the fan take a paint brush and clean the entire fan, get as much of the dust out as you physically can. 
      you can use toothbrushes too if you dont have anything else.

       
      make sure you clean the grill behind the fan too as that is where the dust usually builds up.

       
      removing this dust and hair is the most important part of this clean up.
       
       
      now on to thermal paste.
      remove all the old thermal paste from the heat sink and the CPU with a dry cloth then, use isopropyl alcohol to clean the rest.
      some people seem to think that more is better but this is completely not true! if you put a large amount of thermal paste on the heatsink you will actuall have hotter temps.
      this is due to either:
      A ) the heatsink is not geting enough connectivity to the GPU as the layer of thermal paste is too thick
      B ) too much of it creates small pockets of air, these air pockets become super hot and that causes more heat on the GPU
       
      the correct amount is roughly the size of a pea

       
       
      even that is boarderline too much.
       
      Dont spread it around instead place your heat sink over it as even as possible and screw it down in a X pattern for an even spread.
       
      really hope this helps you and good luck!
       
       
      Continue discussion in original thread here.

      hi all thats my first post here and iam very happy cause this site has hold out so much good information about my dell laptop that i didnt know... i have a dell inspiron 7720 with a gt 650m and i try to do the best i can to keep my gpu cool cause some times it reaches 93 c ... so i was wondering if it worth the time and the work to put thermal paste at the gpu ? has any1 from you do this work befor ? it has considerable effect at the temperatures or there is no need to try it ? also i must say that i have an arctic cooling mx-4 paste but i had buy it 10 years ago is there any problem with this ?
    • By schranzmaster
      • Why should I repaste my Notebook?
      I think that picture says more than any words can say.

      There is to much thermal paste on the thermal surfaces.
      To get the best temperatures as possible, you need a good-pasted system.
      • What do I need?

      - time
      - a bit ''sleight of hand''
      - screwdriver
      - something to remove the thermal paste (I used ''ArctiClean 1 & 2'', for thermal material removing and thermal surface purifing, alcohol should also work)
      - a lint-free cloth
      - a good thermal paste (IC Diamond or Arctic MX-4, i used the one from Arctic)
      - good thermal pads (with at least 6 W/mK thermal conductivity is nice)
      • How to do
      You have to remove the following hardware of the Y580 for repasting:
      • Battery pack
      • Hard disk drive(HDD)
      • Optical drive
      • Keyboard
      • Keyboard bezel
      • System board
      ... You have to remove these screws:

      Be really careful with removing the keyboard. Do it very slowly and smooth and nothing will broke
      This is how the Y580 looks like without the keyboard:

      The same applies to the keyboard bezel. Remove it slowly and smooth, be careful
      The Y580 after removing the keyboard bezel:

      Remove the two screws and you can take out the motherboard
      This is the motherboard with the fan and the two heatsinks for the CPU and the GPU

      • The repasting
      - remove all thermal pads
      - remove the thermal paste
      - clean all components until they ''shine'' like that:

      - after the cleaning replace at first the thermal pads at the back of the GPU (backside of the motherboard) like me:

      - take the new thermal paste and reapply the paste to the core of the 660m and to the CPU
      - place the thermal pads to the parts that I marked, there were the pads placed from factory:

      • The result

      For the testing i modified the vBIOS of the 660m. I rised the core-clock to 1,2 GHz and the memory-clock to 2800 MHz. I also modified the voltage. No overvolt, but i modified it that the voltage stays always at 1,1 V.
      The GTX 660m stays steady at the 1,1 V and it's maximum clocks of about 1200/2800 MHz.
      And for the CPU (i7-3630QM) i always use ''ThrottleStop 5.00'' to get the maximum performance and steady 3,2 GHz on all cores.
      -> My system is throttle-free thats why it can become really hot
      • The temperature of the 660m goes now to a maximum of 70 degrees celcius.

      Before the repasting the absolute maximum temperature for the gpu was 87°C high. (with my overclock)
      • The temperature of the processor, the i7-3630QM, maxes out at 78°C.

      Before the repasting the 3630QM maxed out at 98°C with throttlestop set at 32 multiplier, 100% clock modulation, 100% chipset clock mod and BD PROCHOT turned off.
      All in all, the time you have to spend on reapplying the thermal paste is definitely worth it.
      Lower temperatures means more stable overclocks for technique-enthusiast's or higher life-time of the laptop for the ''normal'' PC-user.
