Clevo P650RS-G Repaste/Cleaning Job

Hello everyone am about to perform surgical procedure on my Clevo P650RS-G (6820HK+GTX 1070)

Going to repaste with Thermal Grizzly Kryonaut from the default Arctic MX-4. Don't like the way thermals have been lately:
CPU max temp: 92 degrees after long session of bf1
GPU max temp: 90 degrees after long session of bf1 (GPU doesn't go above that it just throttles back or holds it)
BTW ambient temps are: 23 degrees

BTW these are with OC of 3.4ghz on the CPU with -140mv(max it will go without edp/current limit throttling)
and 1600mhz and 2349mhz on the memory for the GPU(boost is about 1749~1700mhz normally depending on game though Witcher 3 always runs at 1600mhz no matter what) .

Also going to check the thermal pads and if they are in good shape am leaving them the same or else swapping it for some Arctic thermal Pads.

Items used for the surgery:
Thermal paste: https://www.amazon.co.uk/gp/product/B011F7W3LU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Thermal Pads(if the stock ones are bad): https://www.amazon.co.uk/gp/product/B00UYTT3I2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Arctic clean(To clean off old thermal Paste): https://www.amazon.co.uk/gp/product/B003C2QR4G/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1

Pictures will be added as surgery goes on

Would have loved to have gone liquid metal(Thermal Grizzly Conductonaut) but not too sure about the side effects and safety precautions (don't want to kill my motherboard cos of spillage)

Side note: am still looking for a solution to the EDP throttling of the i7 6820HK hoping the repaste will maybe give it more room to breathe.


: stock application of TIM

: Stock applications of TIM


Cleaned CPU+GPU

Cleaned Heat-sink

New application of TIM
So after:
CPU = 84 degrees(About a 8 degree difference) plus way quieter fans
GPU = 85 degrees(About a 5 degree difference) plus way quieter fans
After the upgrade I can say it was worth it , way quieter laptop as fans are not working as hard and plus a few degrees lower

 

Btw any suggestions as to the best way to apply thermal paste on a laptop as I have only ever done it on desktop?

Nice job.

Probably i will need to do the same as my laptop started throttling heavily.
Any tips or suggestions? (as now you have performed it)

Also i noticed that my temperatures never go over 80 C but it throttles heavily.
So i am not sure what is wrong with it.

Also i was wondering does your laptop throttle under full load?

You can check it using MSI afterburner and some heavy load - as example Heaven benchmark or even MSI Kombustor.

Because now i have following:

Can you please also run Heaven benchmark just after the cold boot and note the result, then keep it running for 30 minutes and benchmark again and compare results?

Can you please share those results as this is what my laptop can do maximum (before it started throttling)

And the other question is - what thickness of thermal pads it is using?

 

Mine doesn't throttle but throttle depends on what throttle you are referring to, are you referring to the CPU or GPU?

 

GPU throttling.

Temperature of GPU is OK (75 C) but under full load it throttles to 1000 - 1200Mhz.
The main reason as i think is Power limit or overheating of Power Delivery elements or some other elements that can not be monitored.

I think that using good thermal pads may improve it.

When this happens i can feel that the top center of notebook is very hot - but the exhaust is not that hot.

 

Hmm pretty strange mine doesnt have that and I easily hit 87 C on full load.

Check your power supply and try and use throttle stop 'limit reasons' or intel XTU monitoring to see what might be limiting your GPU/performance

 

What thickness of thermal pads does it use?

I am thinking to buy something like this:
https://www.amazon.com/ARCTIC-Therm...1502499888&sr=1-1&keywords=ARCTIC+Thermal+Pad

But i am not sure what to buy - 0.5, 1 or 1.5.

 

According to @Meaker@Sager it varies with the position on the laptop. I got the 0.5mm but I would advice getting the 1.0mm ones as these are really thin. But ended up not using it as the ones are there are still pretty good(yours probably are as well depending how long you have had the machine)

 

Hi i have repasted with kryonaut and lapped heat sink. 4-4,1 GHz no problem for everyday usage and for now 4,3 for short cpu tests.





For thermal pads i have used RZR suggestion 0,5 and 1mm mix. Works fine

Nice job, do you have any throttling? (CPU or GPU).

 

Having applied GC Extreme and Kryonaut on my friends P650 maybe i can help you a bit

Kryonaut comes with the spreader in the packet so you could use that to spread the paste over the dies. Takes a bit of practice but if you do it right it would give you a nice spread

The other way is to just apply a drop on each die snd let the pressure of the heatsink spread it out. But with Clevo's reputation for uneven heatsinks, i would suggest spreading it out with the spreader. Worked well on my friends clevo and its holding up with pretty even core temp differentials

I have a question again, upon opening my laptop for a repaste job i found out that the previous owner had REMOVED ALL the thermal pads! ( why the f.... )
i ordered 3 sheets ( 1.5mm 1.0mm. 0.5mm ) and got to work..

However, whatever i do, i end up either with a not properly seating heatsink, or pads not touching..
Is there anyone that can tell with confidence what size(s) ( are there multiple sizes in use at the same time ) are needed for my p650RSG

I saw the post regarding the thicknesses HOWEVER:


the dude/dudette is using different thicknesses pads even just for the Vram... that can not be good?

And therefore i also do not trust his measurements on his "before" photo..

His pictures:

Before:


and after ( look at the thermal pad thicknesses of the vram.. the Vram ( BLUE PADS ) is all the same size but he is using different thicknesses pads )




my board, numbered for your convenience... if you know, please post the thicknesses for the corresponding numbers

 

I have replaced everything (except 13 - i have left the original one) with 1 mm pads. Works OK for me, but you may have a little bit different situation as all heat-sinks are a little bit different.

 

Thank you so much for your reply! Much appreciated!

Do you happen to know if #13 is .5 1.0 or 1.5 thickness? ('no shame if you don't, because all your other info narrowed down my Quest quite a lot!

Thanks from Holland! Much love

 

When i was replacing my thermal pads i have noticed that 13 was thicker than 1 mm, so i left the original one (because i had only 1 mm). If you have both 1 and 1.5 mm you can try it.

 

thanks for your reply, i have 3 different thicknesses on stock. ( 0.5, 1, 1.5mm ) i will try different thicknesses on position #13

Thanks again!

 

I ended up using 0.7mm on all places except 13 ( 1.0mm ) using 1.0mm allround caused a too thick layer of TIM ( thermal compound ) on the GPU and high idle and stresstest temps ( 50/60 idle, and above 90 and throttling when stressed )

now idle temps are 37 ish ( fans completely off ) and 75ish stressed ( automatic fan profile, max 80 percent )

 

You likely tweaked the thickness better than stock

 

I think so, but man what a headache it was.. cutting out all those squares.. cleaning the sinks. Applying TIM. Mounting the heatsink. Dissasembling the heatsink..

Above procedure times 20

But the result is excellent

 

Welcome to my world, only when I did it people got mad at me

 

We don't want people to know that Clevo has a sloppy standard now..

 

No, they just have tolerances to ensure that every reseller gets a good contact every time and with less control over the installation they tend to go on the side of caution.
