proper gtx 780m thermal pad thickness/placing on m18x r2?

Hello!!

While i wait for a pair of gtx 780m cards to arrive i want to ask about where to place and proper thickness of each thermal pad on the gtx 780m . A while back i burnt a few cards because this issue and i dont want it to happen again , there are so many thermal pad manufacturers with different thickness and i dont know which one to buy in case i mess up the pads that i already have placed on the heatsinks . so far i have found this post :

http://forum.notebookreview.com/threads/aw-18-780-thermal-pad-thickness.749932/

I dont know if the same placement / thickness applies for the m18x r2 though

 

Hey

Look at this post - http://forum.notebookreview.com/thr...80m-780m-in-m18xr1.770145/page-3#post-9910840

Also note that heatsinks size varies from each other. Sometimes you will need to stack 0.5mm to 1mm to fill the gap. They are never identical.

 

thanks for the info , is that a gtx 780m on the picture? thermal pad thickness schematic is for an m18x r2 cooler?

 

It's probably M18xR2 heatsink but M18xR1 has same thickness. Im using modified AMD100W M18xR1 heatsinks with GTX 880M and they work flawlessly.

 

That is the basic layout but cover the entire multiple black component section towards the top of the card.. Pads of 0.5mm and 1mm thickness will be needed..

 

Here you go...

 

ok understood !!

thanks for sharing !! now i know exactly what to do !! i am guessing this layout applies for both right and left side correct?

 

Yes, that is correct.

This quick 3 minute video demonstrates how superior the liquid metal options are compared to ordinary thermal paste, including the excellent IC Diamond thermal paste. Coollaboratory Liquid Ultra, Phobya Liquid Metal and Thermal Grizzly Conductonaut are all excellent options that produce similar, if not identical, results.

WOW !! seems Conductonaut is the way to go, amazing temps !!, is that a desktop cpu and the non m gtx 980? . what tool did you used when applying thermal paste ? is that a q-tip?

one more thing , all the above information will work with gtx 675m heatskinks?

 

Be careful with Dell GPUs and using liquid metal pastes.. They aren't as protected as Clevo ones.. Just use Helix GC extreme.. Easy to apply and is extremely good too..

Conductonaut comes with the special cotton swab for applying it and alcohol wipes for cleaning up the old paste. See more detail over in this thread: Thermal Grizzly anyone?

Yes, the EUROCOM Sky X9 is a wicked beast. It has a desktop 6700K CPU and one of the GPU options is a 200W GTX 980 desktop GPU on MXM. It just doesn't get any better than this as far as laptops go.

Yes, you can use it on 675M heat sinks, just apply it only to the copper plate, not the aluminum.

Put some electrical tape strips or use silicon sealant around the die on Dell GPUs to protect the surface mounted components. Here's a photo of what I do with electrical tape... works great.



Here's the whole album to look at: Coollaboratory Liquid Ultra Application | Imgur - Mr. Fox

 

I wouldn't recommend using CLU unless you are very experienced person.

 

nice !! this type of cooling compound lasts as long as conventional paste?

thanks for the advice

 

Longer... much longer. Based on my experience and others using CLU.

 

It is however not worth using it and bricking your GPUs if you are a noob at repasting.. GC Extreme FTW!

 

yeah ... good point though , ill keep that in mind however the possibility of lowering the gpu temperatures with liquid metal compound is so sexy. i will practice with an old laptop i have and use mr. fox electrical tape trick and see how it goes , i have two gtx 280m cards and one gtx 675m that will serve as guinea pig xD

 

It really isn't worth it.. You don't even OC much.. The 1-2C difference between Liquid Ultra and GC Extreme is not worth it...

 

There's no reason to be worried about it if you are careful. I would not recommend it to a sloppy or haphazard person that breaks everything they touch. As long as you don't get it on electical contacts or aluminum, it's no more dangerous than anything else. People that cannot follow directions or dive into uncharted waters like a bull in a china cabinet are dangerous no matter what they are doing. If it's not one thing it's another, LOL.

I tried Gelid GC Extreme and it did not even come close to cooling a heavily overclock 3920XM or 4930MX CPU as well as Liquid Ultra. It was a good 8 to 10°C hotter at 4.7GHz with the Gelid GC Extreme on both CPUs. Maybe at lower clock speeds it's only a couple of degrees, but definitely liquid metal shines at higher overclocks. I also found IC Diamond lasted me a lot longer on heavily overclocked GPUs than the Gelid did. The Gelid did an awesome job at first, but then got dried out and crumbly after about 3 or 4 months of heavy duty overclocking. That happened to me with 780M SLI and 980M SLI, so I just stopped using it because it was not durable enough. It does cool really well in the beginning. I was initially really pleased using it on my GPUs.

Maybe I am just such a big fan of it because I push my CPUs hard all the time, whether I need to or not. I've literally run the Sky X9 CPU at 4.7GHz with c-states disabled since the first Prema beta BIOS mod. So far today, it has been running for 12 hours non-stop at 4.7GHz and core max is 72°C in HWiNFO64 and the idle temp as I am typing this response is 50°C. Pretty hard to beat results like that.

 

im not that noob on applying thermal paste , the issue i had was with the pads but that off the way and with the information i have i think is worth trying so ill give it a go !! thanks guys for your comments !!
