THX a lot!

 

Really looking forward to see your results!

 

It took me about half a day of disassembly, playing and getting the fit just right from scratch the first time. More pads on mine of course

 

Any idea what the optimal thermal pad thicknesses are for the unified HS? I have a set of 0.5/1/1.5/2/3/4/5 mm pads.

I was considering following this image and reducing the thickness of each pad on there by 0.5mm:

 

Usually that is not a bad guide to follow, that extra 0.5mm can make a 12c difference.

 

THX for the guide, I have been waiting for similar thermal pad instruction for a long time!
BTW, you chip voltage also spikes under lite browing or non-load situation. As I have seen I have the latest stock bios (it has "stylenote" boot screen) may be with other bios it could be eliminated...

 

OK ran some quick tests before and after installing the new heatsink: https://imgur.com/a/fSJ5E8X

TL;DR higher temps in CPU-only load, lower temps in GPU-only and combined loads. Overall I would say it's a win and worth the $60 I paid.

 

What IHS did you get exactly?

EDIT: Nvm you are talking about the "heatsink", the shared cooler type right?
And what about the IHS in your signature, did you post any printscreen of before and after?

 

Heatsink, not IHS.

Yeah sorry, i edited my post...
What about the IHS, do you have results from before and after?

 

Unfortunately I do not, the only thing I changed this time was the heatsink.

 

Maybe the bigger brother will get one too.

 

If you want a more unified HS, you could get the P775DM2/DM3 one. Not sure why you would though, as both CPU and GPU are likely to run hotter. 2 of the heatpipes are shared between components and puking heat onto each other, instead of CPU and GPU each having 3 separate heatpipes.

Spoiler: P775DM2/DM3 HS

Spoiler: P775TM/TM1 HS

The upgraded P75xDMx/P75xTMx HS is more similar to the separated P775TMx one, and that to me is is only a good thing. The CPU running hotter in CPU-only loads is a trade-off I'm can take for lower temps in GPU-only and combined CPU+GPU loads.

Spoiler: P75xDMx/P75xTMx stock HS

Spoiler: P75xDMx/P75xTMx upgraded HS

 

Another benefit to the new HS is one of the previously uncovered GPU inductors can be cooled because now there is a heatpipe going over it that you can bridge with a thermal pad:

 

And what are your experiences temperature wise? 70USD investment is more than ok, if it has significant contribution to lower the temps. I cannot wait seeing some results.!

 

I'd rather have the inductors left open if possible, they are best left alone generally.

 

Look up.

 

Why is that? The inductors on the P775 and P870 are fully covered, only this model has that one inductor uncooled.

I also added a thick thermal pad (3mm) to this part of the GPU so that it touches the heatsink, no idea what that component is though:

Spoiler

BTW, what's with the CPU socket not being centered between the heatsink screws on the P75x and P775?



Seems like a great way to ensure that the IHS sider closer to the GPU has less pressure, which I confirmed with pressure paper. I had add toothpicks to that side and screw them in tighter so that pressure was more evenly distributed.

 

My bad, sorry! You have used TGC on cpu amd gpu? The combined temps are convincing!

 

Yup Conductonaut on everything.

 

OK, I am going to order one! 70USD on ali + free shipping, based on your test - thx for your work btw - its worth it!

Could you share how you have masked around the gpu? I am always afraid using TGC on directly
thx

Has anyone tried P775TM separate heatsinks on the P751TM/P751DM2 models?
I want to see how they fit in the chassis, of course the rear side from the bottom cover should be modded, and will be somehow like on 17" model (a better look).

 

Hello everyone!

Currently I am using a Clevo P751TM1-G.
Can I fit a EKWB EK-M.2 NVMe heatsink on my Samsung SM961 m.2 SSD if it is located in the lower bay, right next to the 2.5" slots?

Thank you for your help/answer in advance!

 

Inductors have no moving parts/active components, they don't need a heatsink generally. Where you see them cover d is where something has to reach round them generally or for aesthetic reasons.

 

It has a backplate which could be a problem, but I think it should fit.

I also wonder if any of these fits, second one lacks RPM sensor pin...

 

That looks like the controller will be in the dead spot on the fan and it will mostly cool the flash which does not want to be cooled lol.

 

A couple of thin heatpipes might help a lot, or thin copper vapor chambers under the cooling ribs. Anyway active cooling is a most, so the small vent is what I need.

 

Adjusted pad thicknesses a bit and did paper clip mod on the GPU, dropped GPU temps a few more degrees: https://imgur.com/a/gQu6PZI

I think I'm done here. Time to overclock the GPU and record some updated gameplay footage!

 

Very respectable I look forward to your results.

 

Videos won't be finished uploading until tomorrow, but meantime ran Heaven with +160/+500 OC, max GPU temp 83C after ~20min. Sat at power limit the whole time and max GPU power spiked up to 200W. This heatsink is doing work!



As a baseline, this is with my GTX 1080's usual undervolt of 1848MHz @ 0.913V:







And for @Danishblunt , this is with the GTX 1080 overclocked +160/+500:







Resulting gains over my stock (undervolted) profile are on the order of 5-7%: https://imgur.com/a/y2dZmXs

Personally, I don't think it's worth overclocking the GPU. The performance increase is so marginal due to the 190W power limit. 7% is the best case scenario, and even then it's typically only attainable on the first benchmark run when the GPU is at its coolest and boosting the highest. The margin of improvement declines over time due to Pascal's hardcoded temperature compensation algorithm dropping the core clock as the card heats up.

When overclocked, I actually saw it drop to 1835MHz, which is below my normal undervolt of 1848MHz, in a power-hungry game like Sleeping Dogs with 4x SSAA.

Not to mention, the fluctuating clock speed as the GPU bounces off the power limit constantly causes uneven frame pacing, which makes the experience microstuttery. A locked 1848MHz @ 0.913V is an overall smoother and better experience than the imperceptible few frames per second increase (sometimes) you get from overclocking at the cost of microstutter.

 

When playing with power limits operating at a lower voltage/slightly lower base clock often wins due to a more stable clock.

 

Agreed, stable is better than fluctuating every 1 to 2 seconds. I'll leave the core undervolted and maybe keep the memory at 11GHz, although the gains from overclocking just memory are even smaller, like 1-3%.

Not a fan of GPU Boost 3.0 at all. I still much prefer the older unlocked vBIOSes with GPU Boost removed and unlocked power and voltage limits where we could lock in a rock stable core clock.

 

The old system with a power limit would have been similar.

 

@yrekabakery

Really good job! Nice vids and +rep!
Would you like to share also OBS/GFE settings (alongside your beautiful position and colors of OSD stats)?

 

Very jealous of the interesting and useful upgrades by @yrekabakery to his system. Nice job! I am not nearly confident enough in my tinkering skills to ever try such a thing, but love reading about others doing such things.

With that said, I've become aware of a temperature issue in my own system that either is new, or not something I'd previously noticed, and wanted to ask about it here. While scrolling through the sensor readings from HWInfo during a recent 1.5 hour gaming session, I noticed that my PCH sensor temperature seemed very high, compared to any other temps in the system, and thought I'd post it here and ask if I should be concerned enough to seek a solution, or whether this is not enough of an issue to worry about. Here is the screenshot of the PCH readings:



During the same session, no CPU core was ever above 75C (average in very low 60's), and the GPU was never above 85C (average in the mid 70's). Fans were on Auto, CCC set to Performance mode, and Windows 10 power plan on Balanced, slider at maximum performance. Fans were audible but not really noticeable above the game's audio over the speakers. Exterior of the system remained cool to very slightly warm.

Bear in mind that I don't even know exactly what the PCH is (I know the acronym stands for Platform Controller Hub, but that's the extent of my understanding), or where it would be found on this system, so I'm pretty low on the knowledge curve on this particular issue.

 

The PCH is the chipset and controls the I/O like USB, SATA, NVME etc. It's not actively cooled.

 

Thanks!

What settings do you need? I used the default Modern OSD layout and added GPU voltage and power, and CPU VID, using the HWiNFO plugin in Afterburner.

PCH is the Z370 chipset, it's a chip on the motherboard that manages data flow between CPU, RAM, and I/O devices (storage and peripherals).

The PCH on this system is on the underside of the motherboard. You can see it here, it's the silver square in the center, right above the CMOS battery. The actual chip itself looks like this, but on our system it's covered by a foil heatspreader.

Unfortunately I can't tell you how my PCH temps compare, because my PCH sensor doesn't seem to work. It just shows 0C all the time:



The PCH is supposedly good up to 110C, so while yours is pretty hot, it's not at the thermal trip point yet. The 97C may have just been a brief spike, whereas it normally sits between 80-90C. That being said, the PCH is usually stressed the most during I/O-intensive workloads rather than gaming.

I know you're not keen on tinkering with the system, and as someone who's done it before, it is a bit of an involved process to get the keyboard and top panel off as there are a lot of screws. But what some people have done is taken off the foil and replaced it with a thermal pad to passively cool the PCH using the metal panel and keyboard as a heatsink. You can see here how there's actually a cutout in the plastic shielding for the PCH. I didn't do that to mine though because the PCH is right under the "L" key on the home row, and heating up the keyboard where my fingers usually rest when typing is a big no-no.

 

Thanks for the explanation!

 

Any idea what the difference is between the
P750tm1
P751tm1

Is it like a heatsink cooling change or something else I'm just curious

 

Nope, just different global markets...same laptop.

 

A different keyboard, that's all:

 

I like the look of the bottom keyboard. Any website i could get it from?

 

The resellers of regions that use it would be the ones to check.

 

We are ready for i9-9900K and i7-9700K, now testing 8C/16T BIOS to verify proper operation and thermals. All of our Sky "C" series models would support both of these CPUs.

[links to own site removed by moderator - read forum rules]

Please note that if you plan to use new 8C/16T 9th gen CPU, you would need to update to 8C/16T BIOS with the older CPU (i.e. 8700K) first, then after successful BIOS update, change the CPU to 9th gen, otherwise the system won't POST.
We expect to formally launch 9xxx series CPUs in late October, for pre orders you can check with our Sales Team

Is the bios downloadable for public? thx

 

What's the difference between the P751TM and P775TM audio/speakers? Subwoofer for the P775TM?
