Fighting the heat in notebooks

Recommended Posts

Hello ive 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 with out opening the computer, for those who arent 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 RESPOSIBILITY 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

 

nvidia-system-tools-overclock1.jpg

 

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/

 

Kombustor.jpg

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.:hyper:

 

 

 

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.

111018r4m49phmhb29b84a.jpg

 

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

1_body.jpg

 

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

ThermalCompoundApplied.png

 

 

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 pattern for an even spread.

 

really hope this helps you and good luck!

i do it every 6-8 months or so, but if you live in a dusty area you may need to do it more often.

Just in case you didn't already know don't place your laptop on the bed or carpet as it not only clogs the vents but it sucks up dust.

I did this the other day on an M17x R3. Repasted the CPU and GPU with no problems whatsoever. 

 

Whilst the laptop isn't any cooler while idle it's noticably more silent, and cooler under load.

easier airflow, at least it wasnt for nothing haha

Thanks OP.  Going to mess around with settings later as the fans have been kicking on more. 

Anyone know about undervolting the graphics card in a y500/750m.

becareful with undervolting too, you can still damage.

try MSI after burning and enable unofficial overclocking and see if you cant undervolt with that

OR

use nvidia tools

http://www.nvidia.com/object/nvidia_system_tools_6.06.html

and you can undervolt in there. remember to take it easy and slowly k?

Thanks for that fan info killerii, but thats alot of dust, I started using vent filters on my laptops and cleaning the fan has been alot less in dust and frequency. My Alienware M18x 18.4 hasn`t run hot at all but my Asus G51Jx can heat up a cold cup of coffee in a 1/2 an hour.2016-07-31_16-07-53_709.jpg2016-07-31_16-08-59_487.jpg

@Mr. Fox

Instead of creating new topic, will continue the topic about heat.  I have a 680m that I want to properly get thermal pads and paste for.  It seems the top 2 choices for the GPU Thermal Paste (TIM) is Artic Mx-4 and Gelid GC Extreme (saw IC Diamond 7 but also saw warnings with use).  I know the difference between the two is minimal +/- 1-3 C (I don't plan on any massive overlock, I might bump up the clocks by 50mhz at most if at all) however I am sure the generic stuff included with the card wasn't really great.

 

I saw that @killerii shows just putting a pea size drop on the CPU, but does that apply to the GPU.  I don't remember whose video I watched (want to say Eurocom but could be wrong) where they show dragging the tip so you apply a thin line down the middle of the GPU.  Which is right, a pea or a thin line?

 

Finally the pads is what has me worried.  I have seen mentioned pads needed range from .5, 1 and 2mm (as mentioned or hinted to in all the various post here on techinferno.  Obviously by looking at the card itself you can see the memory is very low, so I would assume 2mm on those, .5 on the highest parts (those odd colored squares with the little chips in between) and 2mm on the outside edge of the card.  I see that the FujiPoly is majorly expensive.  I have "sticky" fingers as I had issues with putting the pads on.  So I wasted some pads.  So I am have seen Laird, 3M as options for pads, any others advised (I saw the instructions for putting actual heatsinks on each part, but that is probably beyond my capabilities at this time (parts so small compared to laptop).

 

My 680m, running the Uningine Valley Benchmark with:

AWM17x R4, with original 3pipe 100w Heat Sink and proper x bracket

DX11

High Quality

Tesselation Normal

Stereo/MultiMon - disabled

AA off

Full screen with system resolution (system is 1920x1080 I would think).

I got a score 1011, min/max 7.5/90.9, fps 40.1 the card hit 66c and no higher (please note it is MSI 4gb in a AW M17x R4 and it has only been in the system for a week - so I know the thermal paste and pads aren't  at their peak efficiency yet).

 

Any advice would be of great help.

be careful with this vent lifters that may keep the dust out but they them selves are also a restriction

either is fine. the idea behind it is that you don't smear it around on the surface creating pockets of air that become an issue with heat transfer efficiency. the pockets of air become super heated and hold that heat between the processor. the line or the pea is likely a similar amount just on an angle.

also its not a case of more is better when your talking about thermal paste.

I knew that but I wanted to make sure the other method showing a line of thermal paste was correct since I followed that for my initial pasting (I didn't order the pricey thermal paste until I knew the GPU would work in my Aw M17x R4 (I know it should but didn't want to spend it on the paste that can't be returned).

 

In regards to cover, that is true.  I know I asked Coolermaster since I have their HAF-X case about adding better dust filters to the outside, but they said the point of the HAF is High Air Flow, you just have to clean the grills more often and putting things on the back would reduce the flow of heat out of the case.

      Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?

      Over the last 10 years I've found laptops throttle the processor speed in order to keep fan noise down. I prefer the fan to run noisily, and the processor to run at full speed. I've developed tried and true mods for lappies and have demonstrated their effectiveness.
       
      I have two Lenovo W541 laptop workstations with I7-4940MX processors and discrete nVidia graphics. On one I overhauled the cooling. Copper shim between CPU and hsf, AS5 on both sides. Shims between hsf and inductors near CPU and gpu, and shim on the gpu.
       
      Used 'thinkpad_acpi' Linux kernel module to set fan to max speed. Ran mprime (prime95 for Linux) AND Unigine Heaven, alternating,  to cure the AS5. Then ran mprime. Temps were slightly high. But laptop processors tend to run hot. 
       
      The I7-4940MX is a 3.1 GHz, 4.0GHz. Turbo processor. The modded machine ran at 3GHz. continuously running mprime, for weeks. The unmodded machine with the same max-fan-speed software tweak and stock thermal-interface material, throttled to 1.7GHz.  at the same running temps.
       
      Clearly, laptop manufacturers are robbing performance off the top, by inferior cooling hardware and materials. Granted, getting the cooling mod to all fit together correctly with smooth, flat surfaces requires hours of work and materials not normally found sitting around the house.
       
      I normally do not mod the CPU die. I abrade copper surfaces down to 1500 grit paper, and then polish with scapings from a bar of buffing compound. Everything is done on 1/2" plate glass to maintain flatness. The final mirror polish is done with the compound granules on a clean, damp cloth.
       
      Desktop processors mostly have slightly raised corners, so smoothness is not as much of concern. You're going to get thermal-interface compond completely covering the center of the processor. The ideal is to fill the microscopic gaps between the cpu die and the hsf, but where there is metal on metal, have it be. 
       
      Metal to metal provides 100s to 1,000s times the heat transfer of thermal paste. But, on a desktop, there are more effective cooling solutions than moving air. Most user are satisfied with their laptops, because the processor doesn't run full speed long enough to make a difference.
       
      But I enjoy tweaking, and I do processor-intensive work, like batch editing 100s of large images, video rendering, security testing, password recovery, network testing; that are all severely compromised by poor, stock laptop cooling solutions.

      Bios Release Version – v2.0.0
       

       
      Updated or Modded Items:
      A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 AND FULL CREDIT GOES TO HIM FOR UNLOCKING!)
      SVL7 Also created the PRR2.EXE tool that allows you to flash the new bios by unlocking it.  (FULL CREDIT GOES TO HIM FOR THAT FILE PRR2.EXE)
       
      Here are ALL the things I've added, modded, and enhanced on this bios -
      I've added FULL LEGACY SUPPORT ON THIS BIOS with ONE or TWO CARDS (SLI).  You can FINALLY use Win 7 OS on your machine and run the 900 series GPU's! 
      This is a MAJOR breakthrough!
       
      LEGACY SUPPORT Confirmed.  Works with 900 series GPu's in single OR SLI formation Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132 Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132 Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6 ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated GOP Driver for Intel Sandy Bridge CPU Updated GOP Driver for Intel Ivy Bridge CPU Updated MAIN GOP Policy module for the m18xR2 Eliminated some code that wasn't used in the m18xR2 Updated CSM Module (v2) Streamline some coding to make mod(s) run a little more efficiently (v2) Added FPARTS.TXT to rar file in v2. (I had forgot to add it in v1) v2.5 to be released shortly.  I've updated a few more modules that I didn't realize could be updated.  (It's only 3 modules, but it's still an update!)   It should be released in about a week.  Hope this helps ya'll!  
      Instructions to flash:
      Use a flash drive to create a boot disk into dos Unzip ALL files into the root of the flash drive (flash.bat, r2final.bin, fpt.exe, flash.bat, prr2.exe, fparts.txt,m18r2.hdr, m18r2.hdr.bin, readmefirst.txt) BOOT INTO DOS – Note, that when you set the bios to legacy in order to boot into dos, you MAY have to reinstall OS!  (Just be prepared to reinstall no matter what) Once you boot into dos, run the file flash.bat It will unlock your bios (THANKS TO SVL7’s BIOS UNLOCKING TOOL – ALL CREDIT TO HIM FOR THIS TOOL!) Let it flash… Reboot your pc, and enjoy the MASSIVE updates!  
      Be on the lookout as I do plan to release newer version with more updates in the future.  However, it wont be for at least a few weeks as I'm now working on legacy support for the m17xR4 and several other systems.  So please be patient!
       
      ENJOY!

      Hello, A couple of days ago I got a new GPU but when I installed it into my computer I was unable to use it but now I know why. When checking the device manger I went into the events tab of my GPU when I went to view all events, I noticed an error it said " event 411 kernel PnP " and It also said Problem Status: 0xC01E0438. I believe this is why my GPU hasn't been working on my PC. If you know how to fix this problem or have info on how to fix this problem that would be greatly appreciated. I'm also using a EVGA NVIDIA GeForce GTX 1660.
